Question 1

What does Sodium AcrylatesCopolymer do in a cosmetic formula?

Accepted Answer

This ingredient is mainly used as a thickener, stabilizer, film-former, and absorbent gel former in creams, gels, sunscreens, and makeup. It helps build cushiony texture, suspend particles, and control water movement in a formula.

Question 2

Is Sodium AcrylatesCopolymer clean?

Accepted Answer

From a clean-beauty perspective, this ingredient has friction because it is a synthetic persistent polymer rather than a readily biodegradable material. Skin irritation is usually low, but some standards flag this class due to environmental persistence and polymer-related restricted-list concerns.

Question 3

Is Sodium AcrylatesCopolymer sustainable?

Accepted Answer

This material is typically made from petrochemical feedstocks and is not readily biodegradable. Its main sustainability concern is environmental persistence after rinse-off or disposal, especially compared with plant-derived or mineral thickeners.

Question 4

Is Sodium AcrylatesCopolymer COSMOS-approved?

Accepted Answer

It is generally not permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic polymer with poor biodegradability alignment. From a Green Chemistry view, it scores weakly on renewable sourcing and end-of-life breakdown, even though it can be effective at low use levels.

Question 5

How does Sodium AcrylatesCopolymer work chemically?

Accepted Answer

This material is a high-molecular-weight, anionic, water-swellable polymer built from neutralized carboxylate-bearing vinyl monomers. It is commonly used around 0.1% to 5% depending on the texture target, with viscosity influenced by pH, salt level, and the amount of water available for swelling.
