POLYACRYLATE-32.

Valuable / FILM FORMING, HAIR CONDITIONING, HAIR FIXING, SKIN CONDITIONING

Polyacrylate-32 is a high molecular weight polymer that creates a protective, ultra-thin film on the skin, critically reducing trans-epidermal water loss and preventing external irritant penetration. It additionally functions as a versatile texture enhancer, conditioning agent, and emulsion stabilizer within formulations, maintaining skin in optimal condition.

Science

Mechanism of Action

Polyacrylate-32 operates by forming a continuous, ultra-thin barrier on the skin's surface and hair. This polymeric film is instrumental in preventing exogenous substances from permeating the stratum corneum, while simultaneously limiting transepidermal water loss, thereby mitigating skin dehydration. It contributes to UV resistance and functions as a skin conditioning agent. Due to its significant molecular weight, dermal and scalp absorption are notably poor, ensuring surface-level activity.

Stability

Polyacrylate-32 is effective as a thickening agent, emulsifier, and emulsion stabilizer, crucial for maintaining homogeneity and preventing component separation in water-based products. While specific pH stability data for Polyacrylate-32 is unavailable, related Polyacrylate Crosspolymer-6 demonstrates stability across a pH range of 2-8. General polyacrylates may precipitate in turbid solutions when exposed to salts above certain temperatures, indicating a potential sensitivity to high ionic strength and heat.

Synergies

  • Other thickeners (e.g., pectins, gums, cellulose derivatives)
  • Fatty alcohols (as an oil thickener)
  • Non-ionic or anionic agents (to enhance foam density and thickness)

Conflicts

  • Salts above certain temperatures (may cause precipitation)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The US FDA recognizes Polyacrylate-32 as a skin protector, affirming a favorable safety profile at low concentrations. Its high molecular weight leads to negligible skin or scalp absorption, deeming it safe in cosmetic formulations designed to be non-irritating. No GHS hazard classifications or specific oral, dermal, or inhalation toxicity data have been identified for this compound. The monomer component, acrylic acid, is non-carcinogenic.
