Question 1

What does Hydroxyethyl Acrylate/ Sodium Acryloyldimethyl Taurate do in a cosmetic formula?

Accepted Answer

This ingredient is a synthetic rheology modifier that thickens water phases and helps stabilize emulsions, gels, and creams. It gives formulas a smooth gel-cream texture and helps keep oil droplets evenly suspended.

Question 2

Is Hydroxyethyl Acrylate/ Sodium Acryloyldimethyl Taurate clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally low-irritation on skin, but it has friction because it is a synthetic, non-biodegradable polymer. Some clean standards and retailer lists restrict or flag this class due to persistence rather than direct skin tolerance.

Question 3

Is Hydroxyethyl Acrylate/ Sodium Acryloyldimethyl Taurate sustainable?

Accepted Answer

This material is typically made from petrochemical-derived monomers through synthetic polymerization. It is not considered readily biodegradable, so its sustainability profile is weaker than that of plant-derived or readily biodegradable thickeners.

Question 4

Is Hydroxyethyl Acrylate/ Sodium Acryloyldimethyl Taurate COSMOS-approved?

Accepted Answer

This ingredient is generally not aligned with COSMOS-natural or COSMOS-organic standards because it is a synthetic petrochemical polymer. It also has a limited Green Chemistry profile due to non-renewable feedstocks and poor biodegradability, despite being effective at low use levels.

Question 5

How does Hydroxyethyl Acrylate/ Sodium Acryloyldimethyl Taurate work chemically?

Accepted Answer

The molecule is a high-molecular-weight polymer built from neutral ester-bearing units and anionic sulfonated units, which allows it to hydrate, swell, and build viscosity in water. It is commonly used around 0.2% to 2% and is valued for electrolyte tolerance, broad pH flexibility, and cold-process formulation compatibility.
