Polyacrylate-1 Crosspolymer ●
TL;DR. This ingredient is primarily a rheology modifier and stabilizer, used to thicken water-based formulas, suspend particles, and improve gel texture. It can also contribute light film formation in skin, hair, and sunscreen products.
What does Polyacrylate-1 Crosspolymer do in a cosmetic formula?
This ingredient is primarily a rheology modifier and stabilizer, used to thicken water-based formulas, suspend particles, and improve gel texture. It can also contribute light film formation in skin, hair, and sunscreen products.
Is Polyacrylate-1 Crosspolymer clean?
From a clean-beauty perspective, it is usually considered low in direct irritation because the molecule is large and has limited skin penetration. The main friction is its synthetic polymer status, residual monomer controls, and increasing scrutiny of persistent polymeric materials.
Is Polyacrylate-1 Crosspolymer sustainable?
This material is typically made from petrochemical-derived monomers and is not readily biodegradable. Its environmental profile is weaker than plant-derived gums or readily biodegradable thickeners because polymer fragments can persist after use.
Is Polyacrylate-1 Crosspolymer COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic standards as a conventional synthetic crosslinked polymer. From a Green Chemistry lens, it scores poorly on renewable sourcing and end-of-life biodegradability, even though it can be effective at low use levels.
How does Polyacrylate-1 Crosspolymer work chemically?
The molecule is a high molecular weight, crosslinked anionic synthetic polymer built from carboxylate-bearing vinyl units, designed to swell in water and create viscosity after neutralization. It is commonly used at low levels in gels and emulsions, often around fractions of a percent to about 1%, and performance depends on pH, electrolyte load, and neutralizer choice.
