Are you familiar with the application of medium viscosity dimethicone oil in creams, the application of high viscosity and ultra-high viscosity dimethicone in hair wash and care, and the application of low viscosity dimethicone in makeup and skin care formulas?

But today we introduce you to a different class of dimethyl silicone oils: ultra-low viscosity dimethyl silicone oils!
Dimethyl silicone, INCI: dimethicone; It is a very common type of cosmetics raw material, widely used in various types of products in the makeup industry

Depending on the degree of polymerization, dimethyl silicone fluids can exhibit different apparent viscosities; For example, common low viscosity (5-20cSt), medium viscosity (50-1000cSt), high viscosity (1000-60000cSt), ultra-high viscosity (> 60000cSt）；

But did you know that there is another class of ultra-low viscosity dimethicone fluids?

Ultra-low viscosity dimethyl silicone oil generally refers to a dimethyl silicone oil with a viscosity of less than 5cSt and strong volatility; By controlling the polymerization of siloxane monomers, this ultra-low viscosity dimethyl silicone oil can be formed. Among them, 0.65cSt is the lowest viscosity and the fastest volatile polydimethylsiloxane known, and its structure is hexamethyldisiloxane.

Substances with such a small molecular weight must have very high requirements for the production process. Dow Corning, the originator of the silicone industry, offers a wide range of ultra-low viscosity dimethyl silicone fluids, including PMX-200 0.65cSt, 1cSt, 1.5cSt, 2cSt, PMX-1184 and more.

Benefiting from ultra-low molecular weights, these ultra-low viscosity dimethicone fluids are all ultra-volatile, and their volatilization rate is even faster than substances such as alcohol.

Therefore, this type of product can be used in some very peculiar cosmetics, such as foaming masks. Foaming mask is a type of product that foams quickly on the surface of the skin when used, and can generally claim the effect of reactive oxygen species moisturizing, unclogging pores and so on. The foaming agent of the foaming mask is generally an ether or 0.65cSt dimethyl silicone oil. However, ethers generally take 15-30 seconds to produce obvious bubbles, which is not conducive to the consumer experience. Using 0.65cSt as a foaming agent can make the mask foam within 5S quickly. 0.65cSt is used in conjunction with ether-like substances to allow bubbles to be produced quickly and uniformly.
