Sodium Acrylate/Sodium Acryloyldimethyl ●
TL;DR. This ingredient is used as a thickener, gel former, emulsion stabilizer, and sensory modifier in creams, lotions, gels, and sunscreens. It helps suspend oils and powders while giving formulas a smooth, cushiony texture.
What does Sodium Acrylate/Sodium Acryloyldimethyl do in a cosmetic formula?
This ingredient is used as a thickener, gel former, emulsion stabilizer, and sensory modifier in creams, lotions, gels, and sunscreens. It helps suspend oils and powders while giving formulas a smooth, cushiony texture.
Is Sodium Acrylate/Sodium Acryloyldimethyl clean?
From a clean-beauty perspective, it has low skin-irritation potential, but it can conflict with standards that limit synthetic, non-biodegradable polymers. The main issue is persistence and restricted-list friction, not typical topical tolerance.
Is Sodium Acrylate/Sodium Acryloyldimethyl sustainable?
This material is typically made from petrochemical feedstocks and is not considered readily biodegradable. Its high molecular weight limits skin penetration, but it may persist after rinse-off or wastewater release.
Is Sodium Acrylate/Sodium Acryloyldimethyl COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic because it is a synthetic polymer that does not align well with biodegradability expectations. Its Green Chemistry fit is weak due to fossil-based sourcing and environmental persistence, despite useful performance at low levels.
How does Sodium Acrylate/Sodium Acryloyldimethyl work chemically?
The molecule is a high molecular weight, anionic copolymer built from neutralized carboxylate and sulfonate-bearing vinyl monomers, which hydrate to form viscosity and stabilize dispersed phases. It is typically used around 0.1% to 2%, works across a broad pH range, and can lose viscosity in high-electrolyte systems.
