Dimethicone, an introduction

Dimethicone is a kind of Silicone, which is made from petrochemicals. Dimethicone comes in different thicknesses. Our Dimethicone is a liquid, about the viscosity of canola oil. But it is not oily. It is odorless and has a silky feel as you rub it onto your skin.

Dimethicone is popular because it is a great emollient (an emollient soften, soothes and protects the skin by acting as a barrier layer on the skin/hair, keeping the natural water/moisture from drying out). For this reason, you will often see dimethicone used in formulas for lotions, as well as hair care products. Usually, it is not more than 1% - 5% of the formula.

Our color-cosmetic customers like to use Dimethicone for several projects:
  • to make a makeup primer
  • to turn their loose powder makeup into a "pressed powder" (see other blog post)
  • to improve the slip, shine and feel of a lipstick or lip gloss
Dimethicone does not dissolve in water and doesn't really like to dissolve in castor or jojoba oil, either! It can be added to a formula which uses some kind of emulsyfing agent, however. Dimethicone will dissolve into such things as essential oils.
