Ammonium Lauryl Sulfate (ALS)

Ammonium lauryl sulfate (ALS) is the common name for ammonium dodecyl sulfate (CH3(CH2)10CH2OSO3NH4). The anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. The combination of nonpolar and polar groups confers surfactant properties to the anion: it facilitates dissolution of both polar and non-polar materials. Ammonium lauryl sulfate (ALS) is classified as a sulfate ester. Ammonium lauryl sulfate (ALS) is found primarily in shampoos and body-wash as a foaming agent.[1]/[2] Ammonium lauryl sulfate (ALS) are very high-foam surfactants that disrupt the surface tension of water in part by forming micelles at the surface-air interface.

Action in solution
Above the critical micelle concentration, the anions organize into a micelle, in which they form a sphere with the polar, hydrophilic heads of the sulfate portion on the outside (surface) of the sphere and the nonpolar, hydrophobic tails pointing inwards towards the center. The water molecules around the micelle in turn arrange themselves around the polar heads, which disrupts their ability to hydrogen bond with other nearby water molecules. The overall effect of these micelles is a reduction in surface tension of the solution, which affords a greater ability to penetrate or "wet out" various surfaces, including porous structures like cloth, fibers, and hair. Accordingly, this structured solution allows the solution to more readily dissolve soils, greases, etc. in and on such substrates. Ammonium lauryl sulfate (ALS) however exhibit poor soil suspending capacity.[2]

Safety of Ammonium lauryl sulfate (ALS)
Ammonium lauryl sulfate (ALS) is an innocuous detergent. A 1983 report by the Cosmetic Ingredient Review, shampoos containing up to 31% Ammonium lauryl sulfate (ALS) registered 6 health complaints out of 6.8 million units sold. These complaints included two of scalp itch, two allergic reactions, one hair damage and one complaint of eye irritation.
The CIR report concluded that both sodium and Ammonium lauryl sulfate (ALS) “appear to be safe in formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin. In products intended for prolonged use, concentrations should not exceed 1%.”

The Human and Environmental Risk Assessment (HERA) project performed a thorough investigation of all alkyl sulfates, as such the results they found apply directly to Ammonium lauryl sulfate (ALS). Most alkyl sulfates exhibit low acute oral toxicity, no toxicity through exposure to the skin, concentration dependent skin irritation, and concentration dependent eye-irritation. They do not sensitize the skin and did not appear to be carcinogenic in a two-year study on rats. The report found that longer carbon chains (16–18) were less irritating to the skin than chains of 12–15 carbons in length. In addition, concentrations below 1% were essentially non-irritating while concentrations greater than 10% produced moderate to strong irritation of the skin.[5]

Occupational exposure
The CDC has reported on occupations which were routinely exposed to Ammonium lauryl sulfate (ALS) between 1981 and 1983. During this time, the occupation with the highest number of workers exposed was registered nurses, followed closely by funeral directors.[6]

Environment
The HERA project also conducted an environmental review of alkyl sulfates that found all alkyl sulfates are readily biodegradable and standard wastewater treatment operations removed 96–99.96% of short-chain (12–14 carbons) alkyl sulfates. Even in anaerobic conditions at least 80% of the original volume is biodegraded after 15 days with 90% degradation after 4 weeks.
We've put together some information about Ammonium lauryl sulfate (ALS) and SLS which will hopefully be useful for you.

We get a lot of questions about sodium lauryl sulphate (SLS) and Ammonium lauryl sulfate (ALS). We would like to reassure you that our safe, natural shampoos are all Ammonium lauryl sulfate (ALS)-free and SLS-free.

We've put together some information about Ammonium lauryl sulfate (ALS) and SLS which will hopefully be useful for you.

WHAT MAKES SLS IRRITATING?
Although sodium lauryl sulphate (SLS) and Ammonium lauryl sulfate (ALS) have similar sounding names and are both classed as anionic surfactants, they have different molecular structures. SLS is a comparatively simple molecule and is therefore quite small in size.
This gives it the ability to penetrate the outer layers of the skin, particularly when used in conditions which encourage the skin's pores to open, such as when in a warm bath or shower.

When SLS penetrates the outer layers of the skin in this way, it comes into contact with more delicate cells that are in the process of being formed in the dermis.

Ammonium lauryl sulfate (ALS) is here that the irritation associated with SLS manifests itself, resulting in reddening and erythema of the skin.

A is an anionic surfactant from the group of alkyl sulphates, INCI name: Ammonium lauryl sulfate (ALS). Ammonium lauryl sulfate (ALS) is mainly intended for personal care products. It has the form of a clear, viscous liquid in colour from colourless to light yellow. The active substance content in the commercial product is around 27%. The microbiological purity of the product is ensured by the addition of sodium benzoate.

The main advantage of the product is the preservation of washing and foaming properties even in the presence of excessive amounts of sebum. ROSULfan A has a much higher resistance to hard water and, at the same time, has a much lower irritating and drying effect compared to Sodium Lauryl Sulfate. In compositions containing Sodium Lauryl Sulfate and / or Sodium Laureth Sulfate, the use of ROSULfAN A reduces the irritant effect of these surfactants. This is especially important in delicate shampoos recommended for sensitive skin.

The product is completely biodegradable and meets the criteria of cosmetics and detergent directives. It also has the Ecocert COSMOS certificate for cosmetic ingredients.

In the construction industry, it is used as an ingredient in agents reducing the weight of drywall, as well as air-entraining and plasticizing admixtures. However, in emulsion polymerization, ROSULfan A provides excellent stabilization of the polymer dispersion at lower pH ranges. Thanks to its use, it is possible to control the particle size, including acrylic, styrene-acrylic systems, vinyl acetate homo- and copolymers, VaE type dispersions and PVC emulsion.

What Is Ammonium lauryl sulfate (ALS)?
Sodium lauryl sulfate and Ammonium lauryl sulfate (ALS) are widely used surfactant in shampoos, bath products, hair colorings, facial makeup, deodorants, perfumes, and shaving preparations; however, they can also be found in other product formulations.

Why is it used in cosmetics and personal care products?
Sodium lauryl sulfate and Ammonium lauryl sulfate (ALS) are surfactant that help with the mixing of oil and water. As such, they can clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away or suspend poorly soluble ingredients in water.

The safety of sodium lauryl sulfate and Ammonium lauryl sulfate (ALS) has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel on two separate occasions (1983 and 2002), concluding each time that the data showed these ingredients were safe in formulations designed for brief, discontinuous use, followed by thorough rinsing from the surface of the skin. In products intended for prolonged contact with skin, concentrations should not exceed 1%.

More safety Information:
Sodium lauryl sulfate and Ammonium lauryl sulfate (ALS) may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European Union .

Is there any truth to the Internet rumors about sodium lauryl sulfate?
Since 1998, a story has been circulating on the Internet that states that sodium lauryl sulfate can cause cancer. This allegation is unsubstantiated and false. In fact, in a 2002 safety review, the CIR Expert Panel assessed all of the data on sodium lauryl sulfate and concluded that “[n]one of the data suggested any possibility that sodium lauryl sulfate or Ammonium lauryl sulfate (ALS) could be carcinogenic. Despite suggestions to the contrary on the Internet, the carcinogenicity of these ingredients is only a rumor.”

Ammonium lauryl sulfate (ALS) & Your Hair: Ingredients and Advice
We often buy shampoo without really knowing what’s in it.

We may have been seduced into said purchase because of an attractive price, an online ad or a recommendation from a friend. Or – and let’s be honest here – simply because we liked the design and colour of the bottle.

It can be very disappointing to discover that, after a few times of using it, our hair does not feel its usual, silky self. We notice a crispiness, lesser defined curls, perhaps even damage. Naturally, this will get us thinking about our choice of shampoo and whether it’s really the right fit for our hair or not. Upon studying the ingredients listed on the bottle and trying to figure out how beneficial or harmful they can be to our curly hair, we are faced with many terms we are completely unfamiliar with.

Among them, we have several types of sulfates, the different types of which can be just as difficult to identify.
One of these sulfates is the Ammonium lauryl sulfate (ALS). You have probably used several products containing this sulfate; it is common in all types of beauty and cosmetic goods including shampoos, but also toothpaste, body gels and soaps. It is a widely used ingredient in these kinds of products, not only because of its cleansing properties but also because it is very economical.

There is a lot of speculation about this particular sulfate and its effects on our hair, with many sources advocating for its use and many others warning us against it. In this article, we’ll get to the bottom of this common shampoo ingredient and its characteristics.

What is Ammonium lauryl sulfate (ALS)?
Ammonium lauryl sulfate (ALS) is an ammonium salt. Although it is originally derived from the coconut, it is commonly created in laboratories for its use in all types of products. As is true for every other sulfate, Ammonium lauryl sulfate (ALS) is a surfactant (“Surface active agent”) – that is, an active agent that creates tension between two surfaces.

In the case of a shampoo, Ammonium lauryl sulfate (ALS) is used to create foam once it comes into contact with water.
This foam helps to wash away grease and dirt in general, as well as to maximize the cleaning efficiency of the product. It also has a psychological, commercial component to it, as many users believe that, the more foam a product generates, the more cleansing it is.
Ammonium lauryl sulfate (ALS) is an improved form of Ammonium lauryl sulfate (ALS). The suffix, “eth”, comes from the added oxygen through a process known as ethoxylation, which makes this agent softer and more water-soluble.

This addition has proven to be a solution against sulfate residues that persist in the skin after washing your hair, and provides a milder, less aggressive agent.

Is Ammonium lauryl sulfate (ALS) Safe to Use on Your Hair?
The problem with sulfates and the foam they create is that they do their job too well. A sulfate basically acts as a detergent that eliminates dirt when we apply it, but also our hair’s natural oils.

As such, it can eliminate our hair’s natural protection. This becomes a problem when using a shampoo with Ammonium lauryl sulfate (ALS) on a regular basis. In this case, we are not leaving these natural oils enough time to form again.
When used sporadically, this sulfate is considered to be gentle on our hair and skin. If used excessively, though, Ammonium lauryl sulfate (ALS) – and all sulfates in general – dry out our hair, to the point of causing skin irritations and even the apparition of dandruff. It also makes our hair that much more brittle.

In the long term, it may not only affect our hair’s health but its colour, too. In the most extreme cases (and, generally, mostly among men), it can lead to hair loss.

HOW IS Ammonium lauryl sulfate (ALS) DIFFERENT?
Ammonium lauryl sulfate (ALS), by contrast, is a slightly more complex molecule and is physically larger with a heavier molecular mass.
This means that it is more difficult for Ammonium lauryl sulfate (ALS) molecules to penetrate the outer layers of the skin and so reach the delicate underlying layers of cells.

Due to this difference, Ammonium lauryl sulfate (ALS) is regarded as being considerably less irritating than SLS – on a scale of 0 to 10, where the potential irritancy of water is 0 and that of SLS is 10, Ammonium lauryl sulfate (ALS) scores around 4 – clearly far less irritating than SLS.
SLS AND Ammonium lauryl sulfate (ALS)-FREE SHAMPOOS

What is Ammonium lauryl sulfate (ALS) and SLS, and what is the difference between them?
Are you the type of person that looks and questions every ingredient in the products you purchase? Don’t worry, that’s a good thing! We’re happy to know people care about what they are in contact with, and we’ve definitely gotten a few questions about our ingredients as well. Which is why we’re here to give you the low down on our Lunette Feelbetter Cup Cleanser and the surfactant we use in it — Ammonium lauryl sulfate (ALS) (ASL), and compare it the one we don’t use, Sodium Lauryl Sulfate (SLS). Try not to get tongue twisted ;)

What is Ammonium lauryl sulfate (ALS) and SLS, and what is the difference between them?
Ammonium lauryl sulfate (ALS) and Sodium Lauryl Sulfate are both anionic surfactants. English, please? A surfactant is a compound that decreases the surface tension between two liquids, a solid or a liquid, or a gas and a liquid. They often act as detergents, foaming agents, and more by helping to mix water with oil and dirt so they can be washed away. Science rules. ASL and SLS have similar-sounding names but what makes them different is their molecular structure.

Although there have been reports that SLS is carcinogenic, there is no scientifically proven link to it. Many reports on the Internet cannot verify this argument with convincing scientific evidence. In fact, cosmetic products in the European Union must comply with strict guidelines and prove their safety before they can be sold.

The flip side of why someone would be against these surfactants is that, because of their efficacy in high concentrations, they are particularly irritating to the eyes and skin. This is being emphasized again and again by most opponents. News flash — all surfactants used are usually harmful to the eyes, whether they are SLS, Ammonium lauryl sulfate (ALS) or other compounds. However, Ammonium lauryl sulfate (ALS) has been found clearly milder than sodium lauryl sulfate in irritation tests

In an article of the "Cosmetic Ingredients Review", only six complaints were reported for shampoos containing up to 31% Ammonium lauryl sulfate (ALS) with 6.8 million units sold. The Cosmetic Ingredient Review report also states, that "Sodium Lauryl Sulfate and Ammonium lauryl sulfate (ALS) appear to be safe in formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin.”
Usually, you only come in contact with surfactants for a short amount of time, like when you’re washing your hair or cleaning your menstrual cup. In this short contact, which is then rinsed with water, the risk of irritation is very low.

Why aren’t we using “soft” surfactants?
A current trend is to use ingredients that are made by marketing campaigns to sound "soft and gentle" and "used earlier". Therefore, in natural cosmetics, for example, glucosides are used, such as Coco Glucosides, Lauryl Glucosides, Decyl Glucosides, since glucosides have a glucose, i.e. a sugar base.

Other alternatives, than glucosides, are weaker in foam than sulfates and harder to thicken. Therefore, cleaners containing sulfates, on the other hand, can easily be thickened to gel without the need to use thickening polymers or gums which, can easily leave a sticky feeling. You don’t want a sticky cup, right? ;)

In order to clean the Lunette Menstrual Cups thoroughly, we have chosen Ammonium lauryl sulfate (ALS) for its effectiveness as one of the ingredients in our Feelbetter Cup Cleanser. Ammonium lauryl sulfate (ALS) leaves no residue on the surface of the cup, and Ammonium lauryl sulfate (ALS) is recognized by the "Allergy, Skin and Asthma Federation" as an ingredient in cosmetic products. Many people still confuse Ammonium lauryl sulfate (ALS) with the "infamous" Sodium Lauryl Sulfate (SLS). The second surfactant we use is called cocamidopropyl betaine. This surfactant is preferred in natural cosmetics, but Ammonium lauryl sulfate (ALS) does not work well enough alone, so we paired it with the more effective Ammonium lauryl sulfate (ALS).

If this little science lesson has got you curious about our Lunette Feelbetter Cup Cleanser, you can buy one on our website! Ammonium lauryl sulfate (ALS) doesn’t contain any artificial fragrances — instead, it’s scented with lemon and eucalyptus oil, selected for their purifying and cleansing properties!

Ammonium lauryl sulfate (ALS) Usage And Synthesis
Chemical Properties yellow viscous liquid

Uses
Ammonium lauryl sulfate (ALS) is a surfactant with emulsifying capabilities. given its detergent properties, at mild acidic pH levels it can be used as an anionic surfactant cleanser. Ammonium lauryl sulfate (ALS) is considered one of the most irritating surfactants, causing dryness and skin redness. Today, it is either combined with anti-irritant ingredients to reduce sensitivity or replaced with a less irritating but similar surfactant, such as Ammonium lauryl sulfate (ALS).

General Description Light yellow liquid. May float or sink and mix with water.
Air & Water Reactions Water soluble.

Reactivity Profile Acidic inorganic salts, such as Ammonium lauryl sulfate (ALS), are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid.

Health Hazard Contact with liquid irritates eyes and may have drying effect on the skin. Prolonged contact will cause skin irritation.
Fire Hazard Special Hazards of Combustion Products: Toxic oxides of nitrogen and sulfur may form in fires.

The product has the ability to produce dense and stable foam, which allows fine and evenly distributed air bubbles to be obtained. Due to these properties, ROSULfan A is used as the main ingredient in cleansing cosmetic products. Ammonium lauryl sulfate (ALS) is dedicated to shampoos, body wash and shower gels.

The product is completely biodegradable and meets the criteria of cosmetics and detergent directives. It also has the Ecocert COSMOS certificate for cosmetic ingredients.

Are Ammonium lauryl sulfate (ALS) and SLS safe to use?
For decades, sulphates have been in the focus of critical parties, even though they are an incredibly efficient fat remover and create a ton of foam. They are considered as environmentally friendly, as they are very quickly biodegradable and won’t typically cause any allergies. Sulfates are recognized among others by the Asthma and Allergy Society in all countries and therefore widely used in most shampoos, sanitary cleansing gels, dishwashers, etc., to dissolve fat the most effectively.

Glucosides are much weaker in foam than sulfates, and they are not as easily thickened as sulfates. You then need polymers or gums as thickeners. However, polymers are banned in natural cosmetics and substances that are permitted in natural cosmetics, such as xanthan gum, cause the gel to leave a sticky feeling on the skin.
Other alternatives, than glucosides, are weaker in foam than sulfates and harder to thicken.

Safety Information:
The U.S. Food and Drug Administration (FDA) includes sodium lauryl sulfate on its list of multipurpose additives allowed to be directly added to food. Sodium lauryl sulfate and Ammonium lauryl sulfate (ALS) are also approved indirect food additives. For example, both ingredients are permitted to be used as components of coatings.
The safety of sodium lauryl sulfate and Ammonium lauryl sulfate (ALS) has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel on two separate occasions (1983 and 2002), concluding each time that the data showed these ingredients were safe in formulations designed for brief, discontinuous use, followed by thorough rinsing from the surface of the skin. In products intended for prolonged contact with skin, concentrations should not exceed 1%.

Ammonium lauryl sulfate (ALS) is also important to consider that not all shampoos include the same proportion of sulfates in their composition, though the percentage does not always appear among the ingredients listed. A good measure of their quantity is to study where they are positioned in the list of ingredients: the higher they show up, the more prominent they are in the product.
If you have curly hair, Ammonium lauryl sulfate (ALS) is important to try to keep it as hydrated as possible for glossy and well-defined locks. Even so, it may not be the best idea to completely stay off sulfate-based shampoos, to achieve a good and deep cleaning of the scalp and hair. Try to incorporate a shampoo containing Ammonium lauryl sulfate (ALS) into your haircare regime once or twice a month tops and stick to a sulfate-free shampoo for regular washing.

When deciding on whether to use a shampoo containing ALES or not – and, if so, how frequently – there are two pointers worth mentioning. If you have dyed hair, you should try and avoid using shampoos containing sulfates, as it can wash the colour out. The same is true for swimmers who frequent the beach regularly since the salt exposure will work cleansing enough. also makes our hair that much more brittle.
In the long term, it may not only affect our hair’s health but its colour, too. In the most extreme cases (and, generally, mostly among men), it can lead to hair loss.

How & When to Use Ammonium lauryl sulfate (ALS)
If you have dry hair or sensitive skin prone to irritation, you should try to avoid shampoos that include the most aggressive types of sulfates. These are (from most to least harmful): sodium lauryl sulfate (SLS), Ammonium lauryl sulfate (ALS), sodium laureth sulfate (SLES) and Ammonium lauryl sulfate (ALS) (ALES).

Even so, this last one is not as aggressive as its lauryl cousin and, when used moderately, shouldn’t have any adverse effect on your hair.
If you have naturally oily hair, you may find that you need a sulfate-based shampoo to clean your hair properly. This may also apply to styling products such as hair gel or creams you use frequently.

Not all sulfates are as strong as Ammonium lauryl sulfate (ALS). There are other sulfates, such as Sodium Coco Sulfate, Cocoamphoacetate and Sodium Cocoyl Glycinate, that are becoming more and more present in different shampoo brands and that are not as strong as Ammonium lauryl sulfate (ALS).
