Question 1

What does Acrylic Acid/Acrylamidomethyl Propane Sulfonic Acid Copolymer do in a cosmetic formula?

Accepted Answer

This ingredient is primarily a rheology modifier and stabilizer, helping gels, creams, and emulsions build viscosity and hold suspended particles evenly. It can also contribute light film formation and a smooth skin feel.

Question 2

Is Acrylic Acid/Acrylamidomethyl Propane Sulfonic Acid Copolymer clean?

Accepted Answer

Clean-beauty frameworks often flag this material because it is a synthetic polymer with potential residual monomer control requirements, not because routine use is strongly irritating. It is generally well tolerated on skin, but its restricted-list friction is higher than many simpler biodegradable thickeners.

Question 3

Is Acrylic Acid/Acrylamidomethyl Propane Sulfonic Acid Copolymer sustainable?

Accepted Answer

This material is typically made from petrochemical-derived inputs and is not considered readily biodegradable. Because it is water-soluble rather than a solid bead, it is different from rinse-off plastic particles, but environmental persistence remains the main sustainability concern.

Question 4

Is Acrylic Acid/Acrylamidomethyl Propane Sulfonic Acid Copolymer COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards as a conventional synthetic polymer. Its Green Chemistry alignment is limited, since it performs at low levels but does not offer renewable sourcing or ready biodegradation.

Question 5

How does Acrylic Acid/Acrylamidomethyl Propane Sulfonic Acid Copolymer work chemically?

Accepted Answer

The molecule is a high-molecular-weight anionic polymer with carboxylate and sulfonate functional groups, which gives strong water-binding, electrolyte tolerance, and viscosity control. It is commonly used at low percentages in aqueous systems, and performance depends on neutralization, ionic strength, and compatibility with cationic conditioning agents.
