Gelest GIA-SRA

Gelest Chromium Oxide Green SR (GIA-SRA) is a green color powder treated with trimethylsiloxysilicate. The hydroxyl-terminated silsesquioxane network in the coating improves adhesion to skin and hair, making it ideal for use in color cosmetic formulations. This pigment is the best candidate for use in long-wearing and water-resistant makeup.

Features & Benefits

Performance Benefits

SR pigments and fillers are coated with a hydroxyl terminated silsesquioxane network that improves adhesion to skin and hair. SR pigments are well suited for use in eye make-up formulations. They are hydrophobic, yet are not overly sensitive to oils including sebum.

  • Water repellency
  • Low oil absorption
  • Forms high solids dispersions
  • Improves wear
  • Improves skin adhesion
  • Improves compressibility
  • Recommended for long wearing eye area products
SR Treatment Benefits
