Polyacrylate-33 ●
TL;DR. This ingredient is primarily a synthetic rheology modifier and emulsion stabilizer. It helps build viscosity, suspend particles, improve spread, and keep water-based formulas uniform.
What does Polyacrylate-33 do in a cosmetic formula?
This ingredient is primarily a synthetic rheology modifier and emulsion stabilizer. It helps build viscosity, suspend particles, improve spread, and keep water-based formulas uniform.
Is Polyacrylate-33 clean?
From a clean-beauty perspective, it is generally low-irritation on skin but has friction because it is a synthetic persistent polymer. Some clean retailers and ecolabels scrutinize this category for microplastic or water-soluble polymer concerns.
Is Polyacrylate-33 sustainable?
This material is typically petroleum-derived and is not readily biodegradable. Its main sustainability issue is persistence after rinse-off use, especially in wastewater and aquatic pathways.
Is Polyacrylate-33 COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic standards because it is a synthetic petrochemical polymer rather than a permitted natural or naturally derived material. Its fit with Green Chemistry is weak due to nonrenewable feedstock and limited biodegradability, even though it can be effective at low use levels.
How does Polyacrylate-33 work chemically?
The molecule is a high-molecular-weight anionic polymer with carboxylate functionality that swells in water to create viscosity and stabilize dispersed phases. It is typically used at low percentages, often below 2%, and performance can be reduced by high electrolyte loads, low pH, or incompatible cationic ingredients.
