Question 1

What does Acrylic Acid/Isobutyl Acrylate/Isobornyl Acrylate Copolymer do in a cosmetic formula?

Accepted Answer

This ingredient is primarily a film-forming resin that helps products create a smooth, flexible, water-resistant coating. It is most relevant in color cosmetics, nail products, and styling formulas where adhesion, gloss, and wear are needed.

Question 2

Is Acrylic Acid/Isobutyl Acrylate/Isobornyl Acrylate Copolymer clean?

Accepted Answer

From a clean-beauty perspective, this ingredient has friction because it is a synthetic polymer with potential concern around residual monomers and limited skin-benefit rationale. It is generally considered low-reactivity once fully polymerized, but it is often restricted by standards that screen out persistent synthetic film formers.

Question 3

Is Acrylic Acid/Isobutyl Acrylate/Isobornyl Acrylate Copolymer sustainable?

Accepted Answer

This material is largely petrochemical-derived and is not readily biodegradable. Its environmental profile is mainly limited by persistence after rinse-off or disposal rather than by acute irritation concerns in finished formulas.

Question 4

Is Acrylic Acid/Isobutyl Acrylate/Isobornyl Acrylate Copolymer COSMOS-approved?

Accepted Answer

It is generally not permitted under COSMOS-natural or COSMOS-organic because it is a synthetic, non-biodegradable film-forming polymer. It aligns weakly with Green Chemistry principles due to persistence and reliance on conventional polymer chemistry.

Question 5

How does Acrylic Acid/Isobutyl Acrylate/Isobornyl Acrylate Copolymer work chemically?

Accepted Answer

The molecule is a high-molecular-weight anionic copolymer with pendant ester groups and carboxylic acid sites, designed to form clear, flexible films as solvent or water evaporates. Use level is formula-dependent, often in the low single digits to higher levels in film-heavy systems, with performance shaped by neutralization, solvent package, plasticizers, pigments, and resin compatibility.
