Cyclohexasiloxane

moisturising

overview

Cyclohexasiloxane is a synthetic silicone used in skincare and cosmetics to improve texture and enhance hydration. It is known for its lightweight, non-greasy, and silky feel, and it helps deliver other ingredients effectively. It is generally considered safe for use in skincare products. However, it is persistent and bioaccumulative in wildlife and humans, and it is classified as expected to be toxic or harmful to the non-reproductive organ system. It is also used in hair care products to add shine and reduce frizz.

benefits

Hydration: Cyclohexasiloxane helps enhance skin's hydration by forming a protective barrier that prevents moisture loss. Texture: It helps to produce an even, smooth formulation that allows the product to spread evenly over the skin. Lightweight: Cyclohexasiloxane is a volatile substance due to its ring-shaped structure. This allows it to evaporate from the skin, leaving behind the product’s ‘active’ ingredients to work their magic.

Skin suitability

All skin types except those that have an identified allergy to it.

additional info

Cyclohexasiloxane is also used in hair care products to add shine and reduce frizz. Cyclohexasiloxane is part of a family of small silicones called cyclomethicones. Cyclomethicones are clear, odorless liquids utilized in skincare products to give your skincare a smooth texture that allows the product’s key ingredients to be delivered evenly to the skin. Cyclohexasiloxane’s structure forms a ring which makes it more volatile or less stable. This instability allows cyclohexasiloxane to evaporate when applied to your skin readily. This characteristic makes cyclohexasiloxane a great ingredient for improving the spreadability of products and ensuring they don’t remain sticky after application. Cyclohexasiloxane gradually evaporates from the skin, leaving behind the other key components in the product to improve the appearance of the skin. This action of evaporation makes it an excellent carrier ingredient. Cyclohexasiloxane is a cyclic silicon-based polymer. **Concerns:** * Persistence and bioaccumulation: Cyclohexasiloxane is persistent and bioaccumulative in wildlife and humans. * Organ system toxicity (non-reproductive): Cyclohexasiloxane is classified as expected to be toxic or harmful to the non-reproductive organ system. * Ecotoxicology: Cyclohexasiloxane is suspected to be an environmental toxin and be persistent or bioaccumulative.
