Super High 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:Super High Viscosity Dimethicone Fluids are are clear, tasteless, and odorless linear polydimethylsiloxane fluids (CAS# 63148-62-9) that have the INCI Name Dimethicone. These fluids range in viscosities from 300,000cSt (centistoke) to 20,000,000cSt. Super High Viscosity Dimethicone Fluids are characterized by their extremely thick viscosities, water repellency (hydrophobic), wide service temperature range, excellent lubricity, miscibility with a wide range of cosmetic solvents, and soft-emollient feel. They are widely used as base fluids in a number of personal care products for hair and skin.

High Viscosity Dimethicone Fluids provide a hydrophobic, protective but breathable barrier to the skin which allow skin to perspire. Dimethicone Fluids are used in a wide variety of antiperspirants, skin creams, skin lotions, suntan lotions, bath oils, hair care products etc. Super Hi Viscosity Dimethicones are compatible with a wide range of cosmetic solvents and are particularly advantageous when blended with cyclomethicones.

In hair care products, they increase body and shine without buildup, and provide better manageability. Higher Viscosity Dimethicones are better suited to add sheen and manageability to hair care products than lower viscosities. They are among the most commonly used conditioning additives. High Viscosity Dimethicones improve both wet and dry compatibility, impart humidity resistance and a soft feel to hair as well as improve shine.
