It helps give skin care products a silky-smooth, spreadable consistency, so key ingredients can be delivered evenly to skin. It is also known to promote aesthetically pleasing finishes that don’t feel sticky, tacky or greasy after application. In hair care, it is used to add shine and reduce frizz. As a raw material, cyclohexasiloxane is a colourless liquid. It is described as a lightweight carrier ingredient since it evaporates from skin, leaving behind the formula’s key ingredients to work effectively. This ingredient has been deemed safe by the Cosmetic Ingredient Review Expert Panel (their report looked at products using between 0.0004-48% cyclohexasiloxane). Related ingredients: Silicone
