Polysiloxane is also called silicone oil or silicone. It and its derivatives are high-quality raw materials for cosmetics, with physiological inertia and good chemical stability, odorless, non-toxic, non-irritating to the skin, and have good skin care functions.

It has lubricating properties, anti-ultraviolet radiation, good air permeability, slow-release effect on flavors and fragrances, good anti-static, and obvious dust-proof function; it has high stability and does not affect the matching with other ingredients.

 Silicone oil has high hydrophobicity, lightness in use, and good stretchability on hair and skin. Silicone oil is used to hydrophobically treat the surface of raw materials to improve the waterproof and sweatproof performance of cosmetics. Representative silicone oils include dimethyl silicone oil and methylphenyl silicone oil.

Simethicone

Dimethicone (polydimethylsiloxane), also known as methyl silicone oil, is a colorless and transparent oil. Depending on the molecular weight, it can be from low viscosity to ointment. Simethicone has various viscosities, generally 5, 10, 100, 350, 1000, etc. Low viscosity is suitable for adding to skin care products to provide a refreshing moisturizing feeling, and high viscosity is suitable for providing strong moisturizing skin care In products, ultra-high viscosity is suitable for adding in hair care products and scar removal products.

Dimethiconol

Generally used is a solution of super high viscosity dimethiconol mixed with low viscosity polydimethylsiloxane, which has an extremely lubricious skin feel, and dimethiconol can give softness to hair It feels smooth and silky, and the emulsification method adopts anionic emulsification, so it has a suitable apparent viscosity, and it is very easy to add to shampoo and shower products and disperse evenly. At the same time, it can stabilize the product viscosity in spring, summer, autumn and winter. Due to the medium particle size of the silicone oil, it can effectively improve the wet cleaning and dry combing performance of the product, and improve the hair knotting phenomenon caused by dryness that often occurs when shampoo products are rinsed and semi-rinsed.

Phenyl silicone oil

    Phenyl trimethicone is a low-viscosity, colorless, transparent liquid, slightly volatile, with a high refractive index, and is easily compounded with alcohols and organic components. It has good anti-stickiness and increases the solubility of silicone oil and other oils. Phenyl silicone oil can be used to brighten the gloss of the paste.

polycyclosiloxane

   Cyclopentasiloxane, commonly known as D5, is a colorless, odorless, non-irritating volatile liquid with good gloss, water resistance, softness, and dryness, and is easy to emulsify (low viscosity). Polycyclic dimethylsiloxane has an appropriate volatilization rate, its evaporation rate is lower than that of water and ethanol, and it has good dispersion and volatility; when it volatilizes, the skin has no cold feeling and no residue, and it can generally be used in volatile In soothing refreshing creams and hair oils.

Polyether modified silicone oil

This type of silicone oil is generally soluble in water, ethanol, and emulsification systems, so it is suitable for adding to skin care water as an emollient, and as a softener in leave-in hair care products.

Amino silicone oil

  In hair care products, it provides good softness and repairs damaged hair properties, and is generally used in hair conditioners, hair masks, and baking ointments.


Silicon elastomer

Typically cyclopentasiloxane, dimethicone crosspolymer or dimethicone, dimethicone/vinyl dimethicone crosspolymer Copolymers, generally have a powdery texture, fill skin wrinkles, and have a soft-focus effect. They are generally used in high-end creams or lotions to adjust skin feel and eye products.
