Polymethylsilsesquioxane is a spherical, fine-particle silicone resin exhibiting a very sharp particle size distribution. It provides excellent lubricity, slip and feel, and water repellency.
Silicones
Silicone Compounds combine the unique properties of silicone fluids with a degree of structure. It is usual for ingredients of this type to lose some viscosity when subjected to shear, but they will regain viscosity/structure with time.
Silicones are helpful materials used in various applications requiring lubrication, texturizing, shine, stability, or protection. They have a wide operating temperature range of -40°C to 200°C, low volatility, and a very low order of toxicity.
They do not degrade in formulation or swell rubber and plastics and are proper lubricants for these materials. Silicones are basically non-hazardous with a deficient order of toxicity, although prolonged contact with the skin or contact with the eyes may cause some irritation.
Simethicone is a pharmaceutical-grade defoamer based on silicone fluids and silica. It is a light gray liquid insoluble in water.
Stearalkonium Dimethicone PEG-8 Phthalate is a complex of a fatty quaternary compound and a carboxy silicone. It is a white to off-white solid with a mild odor and a melting point of 75-80°C.
Stearoxymethicone/Dimethicone Copolymer is an off-white wax, an organomodified polysilicon produced by a reaction between polydimethylsiloxane and fatty alcohol.
Stearyl Dimethicone is an alkyl-modified methylpolysiloxane used in skin care and color cosmetic applications. It is a white wax-like substance with a melting point of about 30°C.
Trifluoromethyl C1-4 Alkyl Dimethicone is a clear liquid a fluoro silicone fluid containing trifluoroalkyl groups in its molecular structure.
Trimethylsiloxyphenyl Dimethicone is a clear viscous liquid that provides increased compatibility with cosmetic ingredients and chemical stability to oxidation.
Trimethylsilylamodimethicone is a silica-based polymer. It is a clear liquid with a low odor. It is a non-reactive amine functional fluid that is substantive and offers excellent wet/dry combing and softness to hair care products.
