Question 1

What does Ammonium Acryloyldimethyltaurate/VP Copolymer do in a cosmetic formula?

Accepted Answer

This ingredient is a synthetic polymeric rheology modifier that thickens water-based formulas and helps stabilize emulsions, gels, and suspensions. It can also add a light film-forming feel in skin care and hair care products.

Question 2

Is Ammonium Acryloyldimethyltaurate/VP Copolymer clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is usually flagged for being a fully synthetic, non-biodegradable polymer rather than for direct irritation concerns. It is generally well tolerated on skin, but some clean frameworks restrict or exclude it because of polymer persistence and petrochemical sourcing.

Question 3

Is Ammonium Acryloyldimethyltaurate/VP Copolymer sustainable?

Accepted Answer

This material is typically made from petrochemical feedstocks and is not considered readily biodegradable. Its main environmental issue is persistence after rinse-off or disposal rather than acute aquatic toxicity.

Question 4

Is Ammonium Acryloyldimethyltaurate/VP Copolymer COSMOS-approved?

Accepted Answer

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

Question 5

How does Ammonium Acryloyldimethyltaurate/VP Copolymer work chemically?

Accepted Answer

The molecule is a high-molecular-weight anionic copolymer with sulfonate groups and lactam-containing segments, which allows it to hydrate in water and build viscosity without traditional neutralization. Typical use levels are about 0.2% to 1.2%, with best performance in roughly pH 4 to 9 systems and reduced viscosity in high-electrolyte or strongly cationic formulas.
