POLYACRYLATE-15.

Valuable CAS 67892-91-5 / FILM FORMING

POLYACRYLATE-15 is a synthetic polymer utilized in skincare for its dual role in formulation integrity and sensory enhancement. It forms a continuous, subtle film on the skin, contributing to product feel, and effectively stabilizes emulsions, preventing ingredient separation within complex formulas.

Science

Mechanism of Action

As a film-forming agent, POLYACRYLATE-15 creates an imperceptible, continuous layer upon the skin surface, improving the tactile experience and visual finish of the product. Internally, its emulsion-stabilizing capabilities are crucial for preventing the phase separation of oil-in-water or water-in-oil systems, thereby upholding the uniformity and efficacy of the formulation over time.

Stability

Optimal stability and swelling performance for POLYACRYLATE-15 are observed within a pH range of 5 to 9. Excursions outside this window, particularly into highly acidic (below pH 5) or highly basic (above pH 9) conditions, can compromise the polymer's integrity and lead to decreased swelling efficiency and physical instability. Careful control during the film coating process and preparation of coating suspensions is essential for maintaining product stability.

Conflicts

  • Residual acrylic acid (monomer) can affect product safety and stability, potentially causing skin irritation.
  • Residual persulfate, an initiator from manufacturing, can detrimentally impact polyacrylate stability.
  • Strong ionic interactions or certain impurities within a formulation may compromise the stability and performance of polyacrylates.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated Acrylates Copolymers, a category inclusive of POLYACRYLATE-15, concluding safety for cosmetic use when formulated to mitigate potential irritation. Stringent manufacturing practices ensure minimal levels of residual monomers, a critical factor for safety. Furthermore, the FDA has approved analogous polyacrylates for applications such as indirect food additives, and related ingredients like sodium polyacrylate are generally considered non-irritating and non-sensitizing under recommended use conditions.
