Question 1

What does Acrylamide/Sodium Acryloyldimethyltaurate Copolymer do in a cosmetic formula?

Accepted Answer

This ingredient is a synthetic thickener and stabilizer that builds gel texture, suspends particles, and helps emulsions stay uniform. It is commonly used in creams, lotions, sunscreens, and gel-serums for a smooth, cushiony feel.

Question 2

Is Acrylamide/Sodium Acryloyldimethyltaurate Copolymer clean?

Accepted Answer

From a clean-beauty perspective, it has friction because it is a synthetic polymer and requires tight control of residual monomer impurities. It is generally low-irritation in finished formulas, but some retailer standards may restrict or question it based on polymer class and impurity specifications.

Question 3

Is Acrylamide/Sodium Acryloyldimethyltaurate Copolymer sustainable?

Accepted Answer

This material is typically petrochemical-derived and not readily biodegradable. Its high molecular weight limits skin penetration, but environmental persistence is a concern compared with readily biodegradable natural-origin thickeners.

Question 4

Is Acrylamide/Sodium Acryloyldimethyltaurate Copolymer COSMOS-approved?

Accepted Answer

It is generally not permitted under COSMOS-natural or COSMOS-organic because it is a synthetic petrochemical-derived polymer rather than an allowed natural-origin material. Its Green Chemistry alignment is weak due to nonrenewable feedstocks and limited biodegradability, despite efficient low-use performance in formulas.

Question 5

How does Acrylamide/Sodium Acryloyldimethyltaurate Copolymer work chemically?

Accepted Answer

This compound is an anionic synthetic polymer network that hydrates in water and increases viscosity through chain expansion and microgel swelling. It is typically used at low percentages, often around 0.2% to 2%, and is valued for broad pH tolerance, electrolyte tolerance, and compatibility with emulsified systems.
