CETEARYL DIMETHICONE/VINYL DIMETHICONE CROSSPOLYMER.

Valuable CAS 243137-50-0 / FILM FORMING, HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, VISCOSITY CONTROLLING

An advanced silicone elastomer designed to bridge the gap between high-performance skin texture correction and sophisticated sensory appeal. This specialized polymer creates a breathable, 3D structural network that instantly refines the skin's surface while acting as an effective stabilizing agent for complex formulations.

Science

Mechanism of Action

This ingredient functions as a soft-focus architectural network on the skin. It utilizes a 'ball-bearing' effect to deliver a velvety, non-tacky finish while filling in micro-depressions such as fine lines and enlarged pores. Beyond its optical blurring capabilities, the crosspolymer network actively traps excess sebum to maintain a matte appearance and forms a protective, non-occlusive film that enhances the durability of active ingredients.

Key findings

  1. 01 Clinical evaluation demonstrates that concentrations between 1-15% significantly minimize pore visibility and normalize surface texture via optical diffusion and sebum regulation.
  2. 02 In medical-grade applications at 30-40%, the polymer shows efficacy in reducing the height and visibility of surgical scars while maintaining film elasticity on mobile areas of the face.

While often used at low levels (0.5-2%) for sensory improvement, clinical pore-blurring benefits require concentrations closer to 5%. Formulations claiming 'pore-minimizing' effects that use this ingredient at the very bottom of the label are likely under-dosing for functional impact.
