CYCLOTETRASILOXANE

Description

Cyclotetrasiloxane, also known as D4 siloxane, is a volatile silicone compound widely used in skincare and haircare formulations. This clear, colorless liquid functions primarily as an emollient and carrier for other active ingredients. Its low surface tension allows for easy spreading and quick evaporation, leaving a silky, non-greasy feel on skin and hair.

In skincare products, cyclotetrasiloxane helps create a smooth, even application and enhances the texture of creams, lotions, and serums. It acts as a temporary barrier, reducing transepidermal water loss and providing a protective film on the skin's surface. In haircare, it aids in detangling, adds shine, and reduces frizz without weighing hair down.

Cyclotetrasiloxane's volatility makes it an excellent choice for formulations where a light, non-occlusive feel is desired. It is often used in combination with other silicones to achieve specific textures and performance characteristics. However, its use has been subject to scrutiny due to environmental concerns, leading some formulators to seek alternatives. When used in cosmetic products, it is typically found in concentrations ranging from 0.1% to 10%, depending on the desired effect and product type.
