What Is Sodium Acryloyldimethyltaurate Crosspolymer?
Sodium Acryloyldimethyltaurate Crosspolymer is a man-made polymer created from sodium acryloyldimethyl taurate that is crosslinked with PPG-3 glyceryl ether triacrylate. In simple terms it is a network of tiny chains that can swell in water and hold oils in place, which is why it is so helpful in creams and gels. The ingredient does not come from plants or animals, instead it is produced in a lab where the raw monomers are mixed, triggered to link together then purified and dried into a fine powder.
The cosmetic world began using this polymer in the early 2000s when formulators needed a more stable alternative to older thickeners that could break down in the presence of salts or high temperatures. Its ability to form smooth, non-sticky textures quickly made it popular in modern skincare and makeup.
Manufacturing involves dissolving the monomers in water, adding a safe initiator that starts the linking reaction, then introducing the triacrylate crosslinker to build a three-dimensional network. After the reaction is complete the mixture is neutralized, filtered and dried. The resulting powder disperses easily in water and swells to create a creamy gel.
You will find Sodium Acryloyldimethyltaurate Crosspolymer in facial moisturizers, lightweight serums, sunscreens, sheet mask essences, eye creams, foundations, primers and aftershave balms. It is also common in anti-aging formulas where a smooth elegant feel is needed.
Sodium Acryloyldimethyltaurate Crosspolymer’s Cosmetic Benefits/Uses
This ingredient earns its place in a formula by improving texture and keeping everything mixed evenly.
- Emulsion stabilising: It helps water and oil stay blended so a cream does not separate on the shelf or on your skin leading to a longer-lasting and more reliable product
- Viscosity controlling: It thickens watery mixtures into silky gels or rich creams without a heavy feel allowing brands to fine-tune how fast a product spreads and absorbs
Who Can Use Sodium Acryloyldimethyltaurate Crosspolymer
This polymer is considered gentle and non sensitising so it fits most skin types including oily, dry, combination and sensitive skin. Because it is non occlusive it will not trap excessive oil, which is helpful for acne prone complexions, yet it still leaves enough slip to keep dry skin comfortable. There are no known skin types that must avoid it unless a person has a specific allergy to the ingredient, which is uncommon.
Sodium Acryloyldimethyltaurate Crosspolymer is produced entirely from synthetic raw materials and contains no animal derived substances making it suitable for vegans and vegetarians. Its manufacturing process does not rely on animal testing in regions that have banned it, though finished product policies can differ by brand.
The ingredient is not known to interfere with pregnancy or breastfeeding. As with any cosmetic ingredient pregnant or nursing women should consult their doctor before introducing new products since individual circumstances vary and this information is not medical advice.
It does not increase photosensitivity so you can use it day or night without added risk of sun related irritation. Always apply sunscreen during daytime routines for general skin health.
Potential Side Effects/Adverse Reactions
Reactions to topical Sodium Acryloyldimethyltaurate Crosspolymer differ from person to person. The points below describe potential issues yet most users experience none of them when the ingredient is correctly formulated and used as intended.
- Mild skin irritation – a small number of people may notice temporary redness, stinging or itching
- Allergic contact dermatitis – rare but possible if the immune system recognises the polymer or residual monomers as allergens
- Eye discomfort – gels that accidentally reach the eye area can cause watering or a gritty feeling until rinsed out
- Reaction on broken skin – compromised or freshly exfoliated skin may feel a brief tingle because the barrier is already weakened
If you experience any persistent irritation or swelling stop using the product and seek advice from a healthcare professional.
Comedogenic Rating
Rating: 0
Sodium Acryloyldimethyltaurate Crosspolymer is water-swellable and forms a light gel film rather than an oily residue, so it does not clog pores or feed acne-causing bacteria. It also lacks fatty acids or waxy chains that typically raise comedogenicity. For these reasons it is considered non-comedogenic and suitable for those prone to acne or breakouts.
The ingredient is often used in oil-free or gel moisturizers aimed at blemish-prone skin, which further supports its low risk profile.
Summary
Sodium Acryloyldimethyltaurate Crosspolymer mainly stabilises emulsions and adjusts viscosity. It forms a three-dimensional network that swells in water, thickens the formula then locks water and oil droplets in place so creams stay smooth and uniform.
Its ability to create elegant textures without greasiness has made it a favorite in modern lightweight skincare, sunscreens and makeup although it is still less well known than classic thickeners like carbomer.
Overall safety data show it is non-sensitising, non-comedogenic and vegan friendly. While reactions are uncommon it is always smart to patch test any new product that contains this or any other ingredient just to be safe.
