C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer ●
TL;DR. This ingredient primarily acts as a rheology modifier and emulsion stabilizer, helping build gel structure, suspend particles, and improve spread in creams, gels, and lotions.
What does C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer do in a cosmetic formula?
This ingredient primarily acts as a rheology modifier and emulsion stabilizer, helping build gel structure, suspend particles, and improve spread in creams, gels, and lotions.
Is C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer clean?
From a clean-beauty perspective, it is often flagged because it is a persistent synthetic polymer, even though its large molecular size usually means low direct irritation potential. It may conflict with standards that restrict synthetic film formers or microplastic-like polymers.
Is C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer sustainable?
This material is synthetic and commonly tied to petrochemical feedstocks. It is not readily biodegradable, so its environmental profile depends more on wastewater capture and sludge handling than rapid breakdown.
Is C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic standards because it falls outside the allowed natural-origin and approved synthetic chemistry categories. Its Green Chemistry fit is limited by non-renewable sourcing and poor biodegradability, despite efficient performance at low use levels.
How does C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer work chemically?
The molecule is a crosslinked, high-molecular-weight network with ionizable acid groups and medium-to-long hydrophobic side chains. Typical use is often below 1%, with viscosity and suspension performance depending on neutralization, electrolyte load, and pH, while high salt or low pH can reduce thickening.
