POLYACRYLATE-30.

Valuable CAS - / NAIL CONDITIONING

POLYACRYLATE-30 is a highly effective synthetic polymer functioning primarily as a super-absorbent thickening agent for water-based formulations. It significantly enhances product viscosity and stability, contributing to a refined texture and improved sensorial experience.

Summary

Thickener Emulsion stabilizer Film-forming agent Texture enhancer Skin conditioning agent

Science

Mechanism of Action

This ingredient operates as a super-absorbent polymer, demonstrating the capacity to absorb 100 to 1000 times its own mass in water. This property facilitates the thickening of aqueous formulations by forming a gel through ionic interactions. Beyond its rheological control, POLYACRYLATE-30 also acts as an emulsion stabilizer, forms a beneficial film on the skin, and contributes to overall texture and skin conditioning.

Key findings

  1. 01 A 2% concentration of Sodium Polyacrylate demonstrated no irritation in an irritant threshold test conducted on rabbits.
  2. 02 Undiluted Sodium Polyacrylate did not induce irritation or sensitization in a study involving 50 human subjects.
  3. 03 Sensitization to Acrylates/C10-30 Alkyl Acrylate Crosspolymer (Carbopol®) is rare, with 1302 patch-tested patients showing no adverse reactions at a 2% aqueous concentration.

Max tested
5%
Sensitization risk Low

The CIR Expert Panel has determined that acrylates copolymers, including crosslinked variants, are safe for cosmetic application when formulated to be non-irritating. Specifically, Sodium Polyacrylate is considered safe. For related Acrylates/C10-30 Alkyl Acrylate Crosspolymer, usage concentrations up to 5% in leave-on and rinse-off products are deemed safe, provided it is not polymerized in benzene. Data on carcinogenicity were insufficient for the benzene-polymerized form of Acrylates/C10-30 Alkyl Acrylate Crosspolymer.
