Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer description

Hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer is a synthetic polymer that has many uses in cosmetics: it primarily functions as a stabiliser, texture enhancer, dispersing agent, and opacifier. It is often combined with ingredients such as isohexadecane, various polysorbates, and a blend of dimethicone- or siloxane-based silicones. These combinations give a cosmetics chemist several options to create appealing aesthetics. The copolymer plays a role in how fast a product “breaks” on skin (meaning how quickly its initial texture changes once applied). For this reason, it’s often used in products with transformative, gel-cream textures. Another helpful aspect of this copolymer is that it can be used within a wide pH range without its efficacy or stability changing. The independent Cosmetic Ingredient Review has deemed this ingredient safe as used in cosmetics. Concentration maximums include 4.3% in rinse-off products and up to 3.6% in leave-on products, including eyeliners and eyeshadows. Cosmetic brands typically use less than those maximum amounts since the safety assessment of this ingredient capped its usage at 3% in leave-on products.

Ingredient ratings


Proven and supported by independent studies. Outstanding active ingredient for most skin types or concerns.


Necessary to improve a formula's texture, stability, or penetration.


Generally non-irritating but may have aesthetic, stability, or other issues that limit its usefulness.


There is a likelihood of irritation. Risk increases when combined with other problematic ingredients.


May cause irritation, inflammation, dryness, etc. May offer benefit in some capability but overall, proven to do more harm than good.
