DIMETHICONE/PHENYL SILSESQUIOXANE/PHENYL BIS-SILSESQUIOXANE CROSSPOLYMER.

Valuable / ABSORBENT

This advanced silicone crosspolymer significantly elevates sensory experience and skin performance. It creates a weightless, protective film, enhancing skin's elasticity and moisture retention while imparting a remarkably smooth, silky feel. Furthermore, it adeptly controls excess oil and visibly minimizes the appearance of fine lines.

Science

Mechanism of Action

DIMETHICONE/PHENYL SILSESQUIOXANE/PHENYL BIS-SILSESQUIOXANE CROSSPOLYMER operates primarily as a sophisticated texture enhancer. Upon application, it forms an imperceptible, uniform matrix on the skin's surface, delivering a sensory transformation that results in a silky-smooth, soft touch. Functionally, it establishes an effective protective barrier, crucial for preventing transepidermal moisture loss and safeguarding skin from environmental aggressors. Its unique polymeric structure also optimizes product spreadability, absorbs superficial sebum to deliver a mattifying effect, and employs a soft-focus mechanism to subtly blur the look of fine lines.

Stability

The ingredient demonstrates robust stability and resistance to oxidation, contributing to an extended product shelf life. It disperses readily in the oil phase. Dispersal in water is achievable with appropriate emulsifiers or water-soluble silicone oils. For optimal integrity, products containing this ingredient should be stored in a sealed container under ambient conditions, protected from moisture and acidic components.

  • Highly acidic compounds
  • Other impurities that could compromise stability

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has rigorously assessed 62 dimethicone crosspolymer ingredients, classifying them as safe for use in cosmetic and personal care products. Due to their substantial molecular size and inherent insolubility in water, these crosspolymers are not expected to permeate the dermal barrier. A Human Repeat Insult Patch Test (HRIPT) conducted on a closely related dimethicone crosspolymer at a concentration of 30% exhibited no evidence of sensitization. While specific SCCS or FDA status for this exact ingredient is not available, its classification within the broader safe dimethicone crosspolymer family supports its use in regulated product categories.
