Production

SLES is prepared by ethoxylation of dodecyl alcohol, which is produced industrially from palm kernel oil or coconut oil. The resulting ethoxylate is converted to a half ester of sulfuric acid, which is neutralized by conversion to the sodium salt.The related surfactant sodium lauryl sulfate (also known as sodium dodecyl sulfate or SDS) is produced similarly, but without the ethoxylation step. SLS and ammonium lauryl sulfate (ALS) are commonly used alternatives to SLES in consumer products.Sodium laureth sulfate (sometimes referred to as SLES) is used in cosmetics as a detergent and also to make products bubble and foam. It is common in shampoos, shower gels and facial cleansers. It is also found in household cleaning products, like dish soap.Sulfate is a salt that forms when sulfuric acid reacts with another chemical. It’s a broader term for other synthetic sulfate-based chemicals you may be concerned about, such as sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES). These compounds are produced from petroleum and plant sources such as coconut and palm oil. You’ll mostly find them in your cleaning and personal care products.

USES

The ingredients SLS and SLES are most commonly found in personal products and cleaning agents such as:

liquid soap
shampoos
laundry detergents
dish detergents
toothpaste
bath bombs
The amount of SLS and SLES in a product depends on the manufacturer. It can range from small amounts to almost 50 percent of the product.Some sulfates occur naturallyTrusted Source and are found in water. Along with other salts and minerals, they help improve the taste of drinking water. Others are found in fertilizers, fungicides, and pesticides.SLS is what’s known as a “surfactant.” This means it lowers the surface tension between ingredients, which is why it’s used as a cleansing and foaming agent.Most concerns about SLS stem from the fact that it can be found in beauty and self-care products as well as in household cleaners.Sodium laureth sulfate (SLES) is a surfactant with a similar chemical formula. However, SLES is milder and less irritating than SLS.Removing dirt from clothing, dishes and our skin is an important part of daily life. From soaps and toothpastes to laundry detergents many products foam when used to unlock their cleaning action.

Sodium Laureth Sulphate (SLES) is an anionic surfactant used in cosmetics for its detergent properties. It is therefore very present in shower gels and shampoos. It is produced from Sodium Lauryl Sulphate (SLS) by ethoxylation, a very polluting chemical transformation, which is why it is prohibited in organic products. Sodium Laureth Sulphate is reputed to be less irritating than Sodium Lauryl Sulphate although the latter is more natural and authorized in Organic, it is the chemical transformation that has softened it and increased its foaming power.

Sodium laureth sulfate is a surface-active agent or surfactant. All surfactants are partly water-soluble and partly oil-soluble. It is this quality that allows oil and water, which normally don’t mix together, to become dispersed.

Description
Used at above minimum concentration, the surfactant molecules become organised in a structure that can trap oil-based dirt from hair, which allows the dirt to be rinsed away. Foam is not responsible for removing dirt, but it allows the hands to work the product through hair or across skin. This helps the mechanical removal of dirt.

Used primarily as a detergent cleansing agent. Can be derived from coconut. It’s considered gentle and effective as typically used in cosmetics products (typically facial or body cleansers and shampoos). Despite the name similarity, sodium laureth sulfate is NOT the same as sodium lauryl sulfate. The former is a milder cleansing agent due to a higher amount and different chemical structure of the fatty alcohols required to manufacture this cleansing agent. The safety of sodium laureth sulfate has been reviewed by numerous industry experts and deemed safe as used.

How It Works

Sodium laureth sulfate works well as a foamer, cleaner, and degreaser. So, if you are using a product that produces lots of suds, bubbles, or foam, it may very well contain SLES.

Cleaning Uses

Sodium laureth sulfate is often used in laundry and hand dishwashing detergents. In addition, it can be found in cleansers, carpet cleaners, toilet cleaning products, stain and odor removers, all-purpose cleaners, etc.

Other Uses

Sodium laureth sulfate isn't just limited to cleaning uses, it can also be found in plenty of personal care products, such as shampoos, facial cleansers, make-up removers, soaps, body washes, bubble baths, and even toothpaste.

Sodium laureth sulfate is a surfactant derived from ethoxylated lauryl alcohol. It is a cleansing and emulsifying agent that is sometimes contaminated with toxic impurities like 1,4-dioxane.

How to tell if a product has sodium laureth sulfate
Sodium laureth sulfate may be listed on ingredient labels under different names including: alpha-sulfo-omega-(dodecyloxy) poly (oxy-1,2-ethanediyl); dodecyl sodium sulfate, sodium salt; PEG-(1,4) lauryl ether sulfate, sodium salt; poly (oxy-1,2-ethanediyl); sodium polyoxyethylene lauryl sulfate; .alpha.-sulfo-.omega.-9dodecyloxy)-, sodium salt; poly (oxy-1,2 ethanediyl), A-sulfo-W (dodecyloxy)-, sodium salt; poly (oxy1,2ethanediyl); polyethylene glycol (1,4) lauryl ether sulfate, sodium salt; polyoxyethylene (1,4) lauryl ether sulfate, sodium salt; sodium PEG lauryl ether sulfate; sodium polyoxyethylene lauryl ether sulfate.

Sles (Sodium Laureth Sulfate) is commonly defined as a surfactant. Sles (Sodium Laureth Sulphate) enables the material produced to foam due to its chemical properties.

Sles (Sodium Laureth Sulfate) has similar properties with SLS (Sodium Lauryl Sulphate). But SLS is more irritating than Sles (Sodium Laureth Sulphate). This is why SLES was developed.

Sles (Sodium Laureth Sulfate) is an anionic surfactant. Such surfactants reduce the surface tension of the water. For this reason, Sles (Sodium Laureth Sulphate) thus reduces the amount of work required for the formation of the foam and increases the stability of the bubbles in it.

However, removing dirt from clothing, dishes and our household surfaces is an important part of daily life, so it’s important to know what you’re really coming into contact with. Many cleaning and personal-care products, from detergents to toothpaste use surfactants to unlock their cleaning action. When used with water surfactants foam and give a product the ability to remove dirt.

One surfactant that helps products clean in this way is Sodium Lauryl Sulfate (SLS).

Another ingredient with a confusingly similar name: Sodium Lauryl Ether Sulfate (SLES) is also found in cleaning products. You may also see it simply called Sodium Laureth Sulfate, with “Laureth” serving as a contraction for the words “Lauryl” and “Ether.” Like SLS, SLES is used for its emulsifying abilities and serves as a super-effective detergent and cleaner.

While the names of these two cleaning agents and their functions may seem interchangeable, there is a distinction between the two — and a reason why you should opt for products that use SLES over those that use SLS.

Sulfonic acid is a compound with general formula RSO2OH, where R is an aliphatic or aromatic hydrocarbon. It is a derivative of sulfuric acid (HOSO2OH) where an OH has been replaced by a carbon group or a compound where a hydrogen atom has been replaced by treatment with sulfuric acid; for example, benzene is converted to benzenesulfonic acid (water-soluble). Sulfonic acid has a sulfur atom bonded to a carbon atom of a hydrocarbon and bonded also to three oxygen atoms, one of which has been attached to a hydrogen atom. Sulfonic acid is acidic due to the hydrogen atom, stronger than a carboxylic acid. Sulfonic acid is one of the most important organo sulfur compounds in organic synthesis. Sulfonic acids are used as catalysts in esterification, alkylation and condensation reactions. Sulfonates are salts or esters of sulfonic acid. Sulfonic salts are soluble in water. Sulfonic acid and its salts present in organic dyes provide useful function of water solubility and or improve the washfastness of dyes due to their capabiltity of binding more tightly to the fabric. They are widely used in the detergent industry. Alkylbenzene sulfonic acid is the largest-volume synthetic surfactant because of its relatively low cost, good performance, the fact that it can be dried to a stable powder and the biodegradable environmental friendliness. Sodium lauryl sulfate (SLS), prepared by sulfation of lauryl alcohol and neutralisation with sodium carbonate, is another common surfactant which has an amphiphilic properties due to C12 chain ( lipophilic) attached to a sulfate group (hydrophilic). This bifunctionality in one molecule provides the basic properties useful in cleaners and detergents. SLS is used as a wetting agent in textiles, foaming and cleaning agent in detergent, cosmetic emulsifier, and sometimes in toothpastes. Sulfonate cleaners do not form an insoluble precipitates in hard water. Ammonium lauryl sulfate (ALS) is a structurally related compound, replacing ammonium group for sodium. They have same applications. But they cause skin and eye irritation, and are therefore not useful in in products that are on the skin for a long time. The ethoxylated SLS and ALS are less irritant on the skin; sodium laureth sulfate (sodium lauryl ether sulfate, SLES) and ammonium laureth sulfate (ammonium lauryl ether sulfate, ALES) which are prepared by addition of ethylene oxide. SLES and ALES are used as a foaming and viscosity builder in shampoos and personal care products (such as bubble bath, shaving cream , ointment, and tooth pastes sometimes) particularly of low pH products. One more common feature of them appears to be the compatibility with other surfactants.

Mainly found in items that are formulated to clean our skin, teeth and clothes, sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) are just a few ingredients that are added to a range of everyday products. Often confused due to their similar names, there’s a big difference between SLS and SLES.

Both made by mixing lauryl alcohol with sulphuric acid and adding sodium carbonate, these sulphate compounds known as surfactants and can be found in many soaps, toothpastes, shampoos and washing liquids that are widely available on the high street. Surfactants mean that a little product can go a long way, all while other ingredients work to nourish, clean and protect.

With their main use to create the well-known foam we all know and love, these lather-creating extras also enable the core ingredients of products such as shower gel, toothpaste and washing liquids to be dispersed effectively across the entire surface area.While both are added to create foam and help to produce a cleaning action, the two ingredients are very different.If you suffer from comedones (more commonly known as whiteheads or blackheads), SLS has also been identified as a key player in increasing the number of these found on the face and body.

Now we know a little more about SLS, sodium laureth sulfate (SLES) is created through a process called ethoxylation (any product ending in -eth has also been through the same process) where ethylene oxide is added to change the makeup of the compound.Safe to use in bath & body products, this process means SLES is much gentler to use on both hair and skin and doesn’t strip the epidermis of any excess moisture, leaving it feeling soft, smooth and nourished.

Here at Bubble T, we choose to stay far away from SLS and use SLES in our shower gel, body scrub and foaming bath jelly to create the foam and lather we all love. When mixed with ingredients such as bergamot oil, orange seed oil, fruit extracts and tea-based infusions, SLES acts as an extremely effective addition to these products.

On the high street, you will find SLS or SLES in many products, including:

Soap
Shampoo
Body wash
Toothpaste
Washing liquid
Shaving cream
Mouthwash
Bubble bath
Moisturiser
Sun cream
.. and many more

Sodium laureth sulfate, an accepted contraction of sodium lauryl ether sulfate, is an anionic detergent and surfactant found in many personal care products. SLES is an inexpensive and very effective foaming agent. SLES, sodium lauryl sulfate, ammonium lauryl sulfate, and sodium pareth sulfate are surfactants that are used in many cosmetic products for their cleaning and emulsifying properties. It is derived from palm kernel oil or coconut oil.
Its chemical formula is CH₃(CH₂)₁₁ₙOSO₃Na. Sometimes the number represented by n is specified in the name, for example laureth-2 sulfate. The product is heterogeneous in the number of ethoxyl groups, where n is the mean. Laureth-3 sulfate is common in commercial products.

Sodium Laureth Sulfate (SLES) is a liquid surfactant used in high foaming cleaners. Foam stability in the presence of soap is much improved over other anionics, therefore this product is recommended for cleaning products containing soap as an ingredient. This product is milder than the SLS.

It is generally defined as a surfactant. Sles (Sodium Laureth Sulphate) enables the material produced to foam due to its chemical properties.

It is an anionic surfactant. Such surfactants reduce the surface tension of the water. For this reason, Sodium Lauryl Ether Sulphate increases the stability of the bubbles in it by reducing the amount of work required to form the foam.
They are organic molecules with a water-hating end (hydrophobic) and a water-loving end (hydrophilic).
Sles can be derived from coconut oil.
It is a chemical that is used extensively in the manufacture of detergent and detergent derivatives.
Sles stands for Sodium Lauryl Ether Sulphate.
It is a water soluble chemical.

Usage areas

It is used in the production of liquid dishwashing and machine detergents, technical cleaning materials.

It is used to reduce surface tension in cosmetic cleaning products such as shampoo, soap, shower gel and bath foam. It is preferred for this process as it is easily diluted with salts and has a good foaming character.

It is used in toothpaste production.

HOW IS IT PRODUCED?

SLES is actually made from SLS, which goes through a process called ethoxylation. SLS can be made from petroleum oil (via the OXO process) or from coconut or palm oil (via the Ziegler process). In both processes, fatty acids are extracted and converted into fatty alcohols, then sulphonated into a crystalline salt. Ethoxylation is the process of reacting ethylene oxide with a chemical to make it less harsh and is widely used in surfactants in the cosmetics industry. Ethylene oxide is a colorless gas with a sweet odor. It is primarily used in the production of other chemicals such as SLES and antifreeze.
In another explanation, SLES; prepared by ethoxylation of dodecyl alcohol. The resulting ethoxylate is converted into the half ester of sulfuric acid, which is then neutralized by converting it into the sodium salt. The product has good dissolving power, favorable hard water resistance and high biological degradation. It also provides formulation and manufacturing convenience. Additionally, it provides some degree of thickening in the final product formulation.
SLES is essentially a synthetic soap. It is an extremely inexpensive and effective surfactant and foaming agent and is basically the chemical used in your soap or shampoo to make it lather.
SLES has a lower degree of skin irritation, ease of squeezing, and insensitivity to hard water. It also has very good properties, is inexpensive and readily available and is therefore easily used by manufacturers.

Used at above minimum concentration, the surfactant molecules become organised in a structure that can trap oil-based dirt from hair, which allows the dirt to be rinsed away. Foam is not responsible for removing dirt, but it allows the hands to work the product through hair or across skin. This helps the mechanical removal of dirt.

Sodium laureth sulfate is an opaque, thick liquid. Its consistency varies, depending on the concentration level.

Sodium laureth sulfate gives thick rich foam and it cleanses the hair. Its thorough action dissolves dirt and grease effectively. When other ingredients - such as sea salt - are added, hair gains volume, body and shine.

Its chemical formula is CH3(CH2)10CH2(OCH2CH2)nOSO3Na. Sometimes the number represented by "n" is specified in the name, for example laureth-2 sulfate. The commercial product is heterogeneous, both in the length of the alkyl chain (12 being the mode of the number of carbon atoms), and in the number of ethoxyl groups, where n is the mean. n=3 is common in commercial products. SLES can be derived from ethoxylation of SDS.

Sodium dodecyl sulfate (also known as sodium lauryl sulfate or SLS) and ammonium lauryl sulfate (ALS) are commonly used alternatives to SLES in consumer products.

Sodium laureth sulfate (SLES), an accepted family of sodium lauryl ether sulfate (SLES), is an anionic dental and surfactant found in personal care (soap, shampoos, toothpaste, etc.). SLES is a cheap and very effective directing agent SLES, sodium lauryl sulfate (SLS), ammonium lauryl sulfate (ALS) and sodium paret sulfate are the effective ingredients used in the effective way and to obtain the emulsion. Those who like soap.

Until recently, one of the most popular cosmetic raw materials, especially among washing cosmetics, was Sodium Lauryl Sulfate (SLS) – a sodium salt of lauryl sulfate. This material, however, was characterized by a significant degree of skin irritation, a relatively low aqueous solubility and limited possibilities to thicken the cosmetic formulation. Today, SLS has been mostly replaced by its ethoxylated derivative - Sodium Lauryl Ether Sulfate (SLES). Despite concerns over the safety of SLES coming from scientists and research groups; These chemicals continue to be the darlings of manufacturers of household products because they're cheap and they perform a simple task really well. They make long-lasting bubbles and it's hard for us to get away from the idea that more bubbles equals better cleaning power. As a result SLES is used in hundreds of products, from dishwashing liquid to shampoo.

Viscosity behaviour
One of the most remarkable characteristics of this type of surfactants is its rheological behaviour.
Aqueous solutions of salt-free ether sulphates have only very low viscosity which strongly increases if a small amount of electrolyte is added.
Alkylether sulphate solutions of 28 % strength and an initial viscosity of about 100 mPa s can be thickened to viscosity values of more than 200000 mPa s by an addition of about 5 % sodium chloride.
With an addition of electrolytes aqueous solutions containing 10 % synthetic active agent attain viscosities of more than 20000 mPa s.
This allows solutions with low synthetic active agent concentrations but having high viscosities to be produced.
The increase in viscosity with increasing electrolyte concentration up to viscosity maximum is characteristic of the behaviour of ether sulphates.
Further addition of electrolyte than results in a decrease in viscosity.
