Question 1

What does HydroxyethylAcrylate/Sodium AcryloyldimethylTaurate Copolymer do in a cosmetic formula?

Accepted Answer

This ingredient is a synthetic rheology modifier that thickens water-based formulas, stabilizes emulsions, and helps suspend pigments or particles. It can also improve slip and cushion in gels, creams, sunscreens, and serums.

Question 2

Is HydroxyethylAcrylate/Sodium AcryloyldimethylTaurate Copolymer clean?

Accepted Answer

From a clean-beauty perspective, it is usually well tolerated on skin, with low direct irritation potential at normal use levels. The main friction is not skin safety, but its status as a synthetic polymer that some clean standards and retailer lists scrutinize.

Question 3

Is HydroxyethylAcrylate/Sodium AcryloyldimethylTaurate Copolymer sustainable?

Accepted Answer

This material is typically made from petrochemical-derived monomers and is not considered readily biodegradable. Its environmental profile is limited by persistence concerns rather than by high acute aquatic reactivity.

Question 4

Is HydroxyethylAcrylate/Sodium AcryloyldimethylTaurate Copolymer COSMOS-approved?

Accepted Answer

It is generally not permitted in COSMOS-natural or COSMOS-organic formulations because it is a synthetic petrochemical polymer. It has weak Green Chemistry alignment due to nonrenewable feedstocks and limited biodegradability, even though it can be used at low levels to build texture efficiently.

Question 5

How does HydroxyethylAcrylate/Sodium AcryloyldimethylTaurate Copolymer work chemically?

Accepted Answer

The molecule is a crosslinked, water-swellable anionic copolymer with hydroxylated ester and sulfonate-containing side groups, which lets it hydrate quickly and build viscosity without traditional neutralization. Typical use levels are often around 0.2% to 2%, and it performs across a broad pH range while tolerating many oils, electrolytes, and UV filters better than many older gel thickeners.
