PRODUCT INFORMATION:
Cyclomethicone 5 is a completely clear liquid ingredient that gives skin care products the quality of being able to spread easily and smoothly, especially across skin.
Its structure is cyclical and has a low molecular weight.
Cyclomethicone 5’s structure limits its ability to penetrate through the dermis layer, which means the molecules mingle with dry skin before evaporating quickly.
Cyclomethicone 5 has many uses and is in skin lotions, fragrances, and hair conditioners.
Because Cyclomethicone 5 evaporates quickly when applied to the skin, some have experienced skin and eye irritation.
Cyclomethicone 5is a general term describing both individual and/or a mixture of cyclic siloxane materials that have many uses and are found in a variety of consumer products.
These materials are derived from the natural elements silicon and oxygen.
Cyclomethicone 5 ingredients are used in cosmetic products where eventual complete evaporation of the siloxane carrier fluid is desired.
In this way they are useful for products like deodorants and antiperspirants that need to coat the skin but not remain tacky afterward.
They provide other important product performance benefits such as facilitating a smooth texture and an even application.
Thus, they may also be found in sunscreens, shampoos, conditioners, moisturizers, lotions, etc.
Cyclomethicone 5 is a clear, odourless cosmetic-grade silicone.
Cyclomethicone 5 is non-greasy and evaporates quickly, making it ideal for use as a base in room and linen mists, as well as in cosmetic products.
Cyclomethicone 5 is becoming more popular in the rubber industry due to its heat resistance, chemical stability, electrical insulation, abrasion resistance, and weatherability, which is expected to drive the Cyclomethicone market.
Cyclomethicones are commonly used as base solvents to blend fragrance oils, perfumes and other cosmetic formulations.
They evaporate quickly and they are miscible with a variety of cosmetics oils, waxes, hydrocarbons and silicone oils.
This property of cyclomethicones makes them a key ingredient in cosmetics as base solvents.
Cyclomethicone 5 is used to blend with fragrance oils and perfume oils for after bath body mists.
Cyclomethicone 5 will produce a luxurious body spray that feels dry.
Cyclomethicone 5 is used in a wide variety of cosmetic applications such as antiperspirants, deodorants, lotions, creams, hair sprays, bath oils, makeup and nail polish.
