SODIUM/ZINC ACRYLOYLDIMETHYLTAURATE/ITACONATE COPOLYMER.

Valuable CAS 2220235-78-7 / DEODORANT

This ingredient is a sophisticated polymeric zinc complex engineered to effectively neutralize malodor molecules without disrupting the body's natural perspiration process. It targets and binds to various volatile compounds, preventing their olfactory detection. This makes it a powerful active for advanced odor control in skincare applications.

Summary

Odor Neutralizer Deodorizing Agent

Science

Mechanism of Action

As a polymeric zinc complex, this ingredient functions by rapidly sequestering and binding to various volatile malodor molecules, including sulfides, mercaptans, thioethers, amines, and ammonia. This targeted action prevents these compounds from reaching the olfactory receptors, effectively neutralizing unpleasant odors while allowing natural perspiration to occur unimpeded.

Key findings

  1. 01 Independent laboratory testing demonstrated efficient reduction of body and cat urine odors with an active zinc equivalent concentration as low as 0.05wt%.
  2. 02 Recommended usage levels for odor neutralization in personal care applications typically range from 0.1% to 6.0%, with specific product formulations (e.g., VELAFRESH ZP30, ZP20, ONZ 405, ZP95) often citing ranges such as 0.5-4.0% or 1.0-6.0% for optimal performance.

Stability

This copolymer exhibits exceptional stability across a broad pH spectrum, from 1 to 12 (or 2 to 11 depending on source). It maintains integrity in hard water conditions up to 400 ppm (at a 5 wt% concentration) and tolerates high ionic strengths up to 35 mS/cm NaCl. Its formulation versatility is notable, as it does not require the addition of auxiliary surfactants, chelants, or solubilizers.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

While the Cosmetic Ingredient Review (CIR) Expert Panel has deemed numerous zinc salts safe for cosmetic use under specific conditions, particularly when formulated to be non-irritating, this precise copolymer has not been individually assessed within that review, nor has a specific SCCS opinion or FDA status been identified for it. However, it is generally considered to have low irritancy.
