Ingredient review
Sodium Acryloyldimethyltaurate Crosspolymer
INCI: SODIUM ACRYLOYLDIMETHYLTAURATE CROSSPOLYMER
A reliable synthetic thickener that gives water-based products a smooth, non-sticky feel without clogging pores.
In plain English
Sodium Acryloyldimethyltaurate Crosspolymer is a synthetic powder that, when mixed with water, swells into a gel. It helps create a silky, lightweight texture in products like serums and moisturizers, making them easy to spread and absorb. Unlike some thickeners, it doesn't leave a heavy or sticky residue, and it also helps keep oil and water mixed together so the product stays stable.

Quick decision guide
Useful, but context matters
Sodium Acryloyldimethyltaurate Crosspolymer is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Acryloyldimethyltaurate Crosspolymer.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A high-molecular-weight synthetic polymer made from acryloyldimethyltaurate monomers crosslinked to form a network. It is produced through controlled polymerization and is supplied as a fine white powder.
How it works
When added to water, the polymer particles absorb liquid and swell, forming a three-dimensional gel network. This increases the viscosity of the formula, giving it a thicker, more luxurious feel. The crosslinked structure also helps stabilize emulsions by preventing oil and water from separating.
Pros
Lightweight texture
Creates a silky, non-greasy feel that absorbs quickly, making it ideal for gel-based moisturizers and serums.
Excellent stability
Helps keep oil and water mixed together, preventing separation and extending the shelf life of the product.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a drawback for consumers seeking plant-based or organic skincare.
Potential tackiness at high levels
If used in very high concentrations, it can leave a slightly sticky or tacky feel on the skin.
Best for
- Anyone who prefers lightweight, non-sticky moisturizers or serums
- People with oily or combination skin who want a matte finish
Use caution if
- Those seeking 100% natural or organic formulations
Usage tips
Safety summary
Sodium Acryloyldimethyltaurate Crosspolymer is considered safe for use in cosmetics. It has low irritation and comedogenic potential, and no significant toxicity has been reported in standard safety assessments.
Research notes
Safety evaluations by the Cosmetic Ingredient Review (CIR) panel have concluded that this ingredient is safe for use in cosmetic products at concentrations up to 2%. Studies show it does not penetrate the skin barrier and is not a sensitizer.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database. No known restrictions at typical use levels.
- Common uses
- Gels, Serums, Moisturizers, Sunscreens, Hair styling products
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in very low concentrations, and its environmental impact is considered minimal compared to microplastics.
Good to know
- Often listed near the end of ingredient lists because only a small amount is needed.
- Can be used in both rinse-off and leave-on products.
- Does not typically cause irritation or clog pores, making it suitable for sensitive skin.
