Are you familiar with the application of medium viscosity dimethicone in creams, the application of high viscosity and ultra-high viscosity dimethicone in hair care, and the application of low viscosity dimethicone in makeup and skin care formulas?
But today we introduce to you a different type of dimethicone: ultra-low viscosity dimethicone!
Dimethicone, INCI: polydimethylsiloxane; is a very common cosmetic raw material and is widely used in various products in the cosmetics industry
Depending on the degree of polymerization, dimethicone can show different apparent viscosities; such as common low viscosity (5-20cSt), medium viscosity (50-1000cSt), high viscosity (1000-60000cSt), ultra-high viscosity ( >60000cSt);
But did you know that there is also a type of ultra-low viscosity dimethicone?
Ultra-low viscosity dimethyl silicone oil generally refers to dimethyl silicone oil with a viscosity lower than 5cSt and super volatility. This ultra-low viscosity dimethyl silicone oil can be formed by controlling the polymerization of silicone monomers. Among them, 0.65cSt is the polydimethylsiloxane with the lowest viscosity and fastest volatilization known so far, and its structure is hexamethyldisiloxane.
For a substance with such a small molecular weight, the requirements for the production process must be very high. Dow Corning, the originator of the silicone industry, can provide a variety of ultra-low viscosity dimethyl silicone fluids, including PMX-200 0.65cSt, 1cSt, 1.5cSt, 2cSt, PMX-1184, etc.
Benefiting from their ultra-low molecular weight, these ultra-low viscosity dimethicone fluids are extremely volatile and evaporate even faster than alcohol and other substances.
Therefore, this type of product can be used in some very unique cosmetics, such as foaming masks. Foaming facial mask is a type of product that quickly foams on the skin surface when used. Generally, it can claim the functions of active oxygen moisturizing and unclogging pores. The foaming agent for foaming masks generally uses ether substances or 0.65cSt dimethyl silicone oil. However, ether substances generally take 15-30 seconds to produce obvious bubbles, which is not conducive to consumer experience. Using 0.65cSt as the foaming agent can quickly foam the mask within 5 seconds. 0.65cSt is used in conjunction with ether substances to generate bubbles quickly and evenly.
