AMODIMETHICONE

Amodimethicone is particularly effective at protecting hair from damage caused by heat styling, chemical treatments, and environmental factors like UV radiation and pollution. 
Amodimethicone is a high molecular weight, low amino group content silicone polymer containing two amino groups.
Amodimethicone is used in shampoo, rinse-o conditioner, hair coloring and hair styling products.

CAS Number: 851635-19-3

Synonyms: N'-[3-[[dimethyl(trimethylsilyloxy)silyl]oxy-methyl-trimethylsilyloxysilyl]-2-methylpropyl]ethane-1,2-diamine, Amodimethicone (800 cst), SCHEMBL13042984Gluconamido Amodimethicone, dimethylsiloxane/[(2-aminoethyl)amino]propylsilsesquioxane, DIMETHOXYSILYL ETHYLENEDIAMINOPROPYL DIMETHICONE.

Amodimethicone is a silicone derivative of dimethicone, used mainly in shampoos and hair care for its electrostatic properties.
Amodimethicone makes the hair soft, easy to comb and shiny.
The advantage of this silicone compared to dimethicone is that, although it is dicult to remove with a shampoo, it prevents other polymers of the same type can "re-deposit" on itself, so the decriated accumulation with dimethicone, which makes hair heavy, no longer exists here.

Like dimethicone, the molecule does not pose a particular problem for human health (directly in any case).
However, Amodimethicone is not very biodegradable and its impact on the planet both from the point of view of its manufacture and of its release into nature does not.
Amodimethicone is a type of silicone used in cosmetic and personal care products for its conditioning and detangling properties. 

Its chemical formula is C15H42N2O3Si4, and it is a clear to slightly hazy liquid with a low viscosity. 
Unlike many other types of silicones, Amodimethicone is water-soluble, which means it can be easily rinsed off with water without leaving a heavy or greasy feeling on the hair or skin. 
Amodimethicone works by forming a thin, protective layer around the hair shaft, which helps to prevent damage from heat styling and other environmental stressors. 

Some common products that contain Amodimethicone include hair conditioners, shampoos, and leave-in treatments.
Amodimethicone is a milky, white silicone emulsion (amino-modifed polydimethylsiloxane emulsion) offering excellent conditioning & softening properties.
Water soluble silicone emulsion for use in hair conditioners, hair spritzes and styling products. 

Protects the hair shaft, moisturizes hair, gives softness and shine. Adds a silky feel to skin care creams and reduces greasiness.
Amodimethicone is an abbreviation of “amine-functionalized silicone,” which is a family of silicones modied to have specic properties.
The simplest, and perhaps most well-known silicone, polydimethylsiloxane (dimethicone, by INCI naming standards), consists of methyl groups (-CH3) as the pendant group along the backbone of the polymer chain.

Amine-functionalized silicones have been chemically modied so that some of the pendant groups along the backbone have been replaced with various alkylamine groups (-R-NH2).
These amine groups become positively charged in aqueous solutions because of their electron-donating (basic) tendencies, yielding an inorganic, cationic polymer.
Amodimethicone works as an anti-foaming agent, skin protectant, skin conditioning agent, and hair conditioning agent.

Amodimethicone prevents water loss by forming a barrier on the skin.
Like most silicone materials, dimethicone has a unique uidity that makes it easily spreadable and, when applied to the skin, gives products a smooth and silky feel.
Amodimethicone can also help ll in ne lines/wrinkles on the face, giving it a temporary “plump” look.

Amodimethicone is a type of silicone compound used primarily in the formulation of personal care and cosmetic products. 
Amodimethicone belongs to a class of modified silicones known as aminosilicones. 
The name "amodimethicone" comes from the combination of amino groups (containing nitrogen) and dimethicone (a type of silicone). 

This compound is typically used for its ability to provide conditioning, smoothing, and frizz-control benefits in hair and skin care products.
Amodimethicone is a popular ingredient in hair care products because of its conditioning and detangling properties. 
It is often used in shampoos, conditioners, and leave-in treatments to help reduce frizz, enhance shine, and improve manageability. 

One of the key advantages of Amodimethicone over other types of silicones is its water solubility, which means it can be easily rinsed out of the hair without leaving a heavy or greasy feeling. 
This makes it a popular choice for leave-in conditioners and other hair care products that are designed to provide long-lasting benefits without weighing hair down or causing build-up.

Amodimethicone can improve dry、wet combming property of shampoo and conditioner .
Amodimethicone forms a smooth and rm lm which repairs damaged hair, with excellent hair conditioning, deposition and antistatic ability.
Amodimethicone is a reactive cationic emulsion containing 36% amodimethicone polymers. With excellent conditioning ability, it’s widely used in shampoo, conditioner, hair dressing treatment and styling products to provide favorable wet & dry combability and puy feel.

With strong anity to hair, it can repair dyed and cold waved hair, damaged, rough, dry hair caused by chemical process, make hair smooth, easy to manage.
These inorganic cationic polymers deposit onto the hair because of the electrostatic attraction between the polymer and the negatively-charged protein surface of the cuticle.
In this manner, they behave much like polyquaternium materials (organic cationic polymers), which are excellent conditioning agents as well.

The charge density of the polymer can be varied by changing the placement and quantity of the amine groups.
A polymer with greater charge density will be more substantive to the hair than one with lesser charge density.
One interesting property of these polymers is that they provide selective conditioning to the areas most in need of it.

The mechanism by which they accomplish this is, again, electrostatic attraction.
Highly damaged areas of the hair cuticle possess higher negative charge density, which enhances the anity of the cationic polymer to that specic area.

Amodimethicone consists of a silicone backbone with amino-functional groups attached. These amino groups help the silicone to bond with the hair or skin, enhancing its performance as a conditioning agent.
Its structure allows it to form a thin, non-greasy, and protective film over the surface it is applied to, such as hair or skin, which helps to smooth and hydrate.

Boiling Point: 200-350°C
pH: 5.5-7.0
Solubility: Soluble in water
Viscosity: Low

A modified dimethicone-type silicone molecule that also contains amino-groups. Having amino-groups means that Amodimethicone also has Nitrogen in its molecule that likes to have a positive charge. 
Positively charged (or quaternised) molecules are substantive to skin and hair as those are negatively charged surfaces and are excellent film formers. 
Amodiemthcone is no exception and it is especially recommended for hair-care products for its long-lasting hair conditioning benefits.

Once the amine-functional silicone is deposited onto the surface of the hair, it spreads out and forms a cross linked lm when it dries.
This cross linked lm can last through several washings, which is considered to be advantageous in most applications.
A unique property of these polymers is that once in place on the surface of the hair, they repel further deposition of amine-functional polymers on top of the existing layer, preventing buildup.

This cross-linked lm seals moisture inside the hair shaft, holding the cuticle at and providing excellent wet and dry comb-ability.
An additional benet of these silicones over other cationic polymers (such as polyquats) is their high refractive index, which gives the hair a high degree of gloss and shine.
Silicones, including amodimethicone, also protect from thermal damage resulting from styling tools, such as hot rollers, curling irons, and blow dryers. This phenomenon is due to their very low thermal conductivity -- much lower than water, glycerin, or mineral oil.

This reduces heat transfer through the hair surface to the cortex of the hair.
Very high temperatures found when styling or processing hair (sometimes as high as 100°C to 160°C) are capable of vaporizing water contained within the cortex.
Amodimethicone is extremely important to maintain proper hydration of the hair because water has a very high specic heat which helps protect the hair from getting too hot.

Hair that reaches too high temperatures can suer permanent damage to the delicate keratin brils in the cortex.
A protective layer of amodimethicone on the surface can help prevent or reduce damage done in this manner.
One frequent question that arises is whether these amine-functional silicones -- amodimethicone in particular -- are water soluble.

This question is most relevant for those on a shampoo free routine who wash with conditioners.
They fear that the only way to prevent buildup of these silicones is to use a traditional surfactant such as sodium lauryl or laureth sulfate, cocamidopropyl betaine, or the ammonium lauryl or laureth sulfates.
Amodimethicone helps reduce tangles, frizz, and static in hair, making it easier to comb through and style.

Amodimethicone provides long-lasting hydration for both hair and skin by creating a barrier that prevents moisture loss.
It smooths the surface of the hair and skin, enhancing shine and reducing the appearance of frizz or rough texture.
In hair products, it offers some degree of heat protection, reducing damage from styling tools such as blow dryers and straighteners.

Despite being a silicone compound, it does not leave a greasy or heavy residue on the skin or hair, making it suitable for use in lightweight products.
Amodimethicone is is the the polyethylene glycol (PEG) ether of tridecyl alcohol, with 12 units of ethylene oxide in the molecule (CosmeticsInfo.org); it is sometimes derived from vegetable oil.
Amodimethicone is seen in a variety of cosmetics and personal care products as both a surfactant, and is known to prevent the buildup of silicones, or counteract other products that build up in hair.

Therefore, Amodimethicone is most often found in shampoos, conditioners, and other hair care products (NCCosmetics).
Amodimethicone are controversial ingredients in cosmetics and beauty products, in part because of their ability to penetrate the skin and be absorbed into the body, or assist other chemicals and ingredients in absorption.
According to research, lower molecular weight PEG ingredients were minimally absorbed and higher molecular weight PEGs (PEG-75 and greater) were not absorbed through intact skin.

Therefore, Amodimethicone may be absorbed through the skin due to its low molecular weight of 12.
Amodimethicone is an amine-functionalized silicone made from dimethicone where the methyl groups along the backbone are replaced with alkylamine groups which become positively charged in aqueous solutions yielding an cationic polymer.
Dimethicone is made from Amodimethicone which is produced by powdered silicon (silicone dioxide) and methyl chloride.

Amodimethicone is then hydrolyzed to give a hydrolysate of polysiloxanes.
In a polymerization reaction with water the polysiloxanes are then polymerized to linear silicone polymers with dierent chain length (dimethicones).
Amodimethicone is synthesized by reacting dimethylamine with a silicone compound known as dimethyldichlorosilane, followed by hydrolysis and further reaction with a carboxylic acid. 

This process results in the formation of the Amodimethicone molecule, which can then be purified and used in cosmetic and personal care products.
