Silky Slip (SS)-Treated

Silky Slip (SS)-Treated Pigments; INCI name: Stearyl Triethoxysilane

Silky Slip (SS)-treated pigments are hydrophobic and resist wetting by water. The stearyl silane imparts the excellent wetting properties of the shorter chain silanes with more emollient skin feel in powders and dispersed systems.

Silky Slip Treatment Benefits:

  • Lubricious skin feel and aesthetics
  • Enhanced compressibility in pressed powders
  • Water repellency
  • Improved wetting and dispersion capability
  • Improved skin adhesion
  • Enhanced cushion due to treatment melt point similar to skin temperature

Recommended Uses:

  • Loose powders
  • Pressed powders
  • Water-in-silicone foundations
  • Water-in-oil foundations
  • Powdercream products
  • Sunscreens

Powder Cream Concealer with ML Pigments and SerebriteTM SS

This high coverage formula applies like a cream, yet has the dry feel of a powder. Dimethicone Maximum Loading (ML) pigments allow for higher pigment loading due to low oil absorption and excellent wetting proprieties. Seribrite™ SS is added as a boron nitride replacement due to its whiteness, slip, and creamy feel upon application.
