SeraSense SF 1.3 is a 1.3cS low molecular weight straight chained low viscosity silicone for use in a wide variety of formulations. In cosmetics applications, the volatility of 1.3cS dimethicone makes the ingredient incredibly useful as a cosmetic grade solvent with a low evaporation point meaning that as it evaporates, it cools the skin less that other solvents, such as water or alcohols. These qualities are similar to that of SeraSense SF CM5 (cyclopentasiloxane or D5) and so, for those who wish it, this is a good potential replacement for D5 with all the skin feel benefits that silicones offer.
This product contains <0.1% D4 and D5.
KCC Beauty dimethyl silicone fluids known chemically as polydimethylsiloxanes, are available in various viscosities ranging from 0.65cS to 60,000cS. They are clear, non-toxic, inert and odourless fluids.
Recommended usage level is 1.0 – 50% however depends heavily on application.
