Super Low Viscosity Dimethicone Fluids

Chemical Name: Linear Polydimethylsiloxane Fluids

What are Dimethicones? Dimethicones are linear, Polydimethylsiloxanes with viscosities ranging from 1.5cSt to 20 million cSt. They are clear, colorless, odorless and inert fluids that are used in a wide array of cosmetic formulations. Dimethicones are characterized by their softening effect on skin and hair. They are hydrophobic (water-repellent) without restricting respiration of the skin, which makes them beneficial in skin creams and lotions. The inertness of the fluids enhance the stability and shelf life of the cosmetic formulations.

Dimethicones are compatible with a wide variety of cosmetic solvents and are particularly effective when blended with cyclomethicones. Lower viscosities have lower surface tensions and greater miscibility in mineral oils, light esters and suntan agents.

Due to these characteristics, Dimethicones are widely used in skin creams, suntan lotions, hair conditioners, bath oils, shaving foams, shampoos, etc..

Use: Use: Super Low-Viscosity Dimethicone Fluids are clear, colorless, and odorless linear polydimethylsiloxane fluids that range in viscosities from 0.65cSt (thinner than water) to 2cSt (centistokes). Super Low-Viscosity Dimethicone Fluids are characterized by their fast rate of evaporation , low surface tensions, low pour points, low temperature stability, excellent lubricity, miscibility with a wide range of cosmetic oils, and low heat of vaporization.

Super Low Viscosity Dimethicone Fluids are used as a diluent and carrying agent in a wide variety of antiperspirants, skin creams, skin lotions, suntan lotions, bath oils, hair care products etc.

Note: PSF-0.65cSt Hexamethyldisiloxane has the lowest viscosity, lowest surface tension, and fastest evaporation rate of all Dimethicone and Cyclomethicone fluids.
