Cyclohexasiloxanes

Cyclohexasiloxanes are a group of cyclic silicone compounds with the general formula [(CH3)2SiO]n, where n is typically 6. They are also known as D6 siloxanes. These substances are colorless, odorless liquids that are volatile and have a low viscosity. Their unique properties, including their ability to spread easily and leave a smooth, non-greasy feel, have led to their widespread use in a variety of consumer products.

In the personal care industry, cyclohexasiloxanes are commonly found in cosmetics, hair care products, and antiperspirants. They function as emollients, skin conditioners, and solvents. In skincare, they can help to improve the texture and spreadability of creams and lotions, providing a silky sensation. In hair care, they are used in conditioners and styling products to reduce frizz, add shine, and make hair easier to comb. Their volatility allows them to evaporate from the skin or hair after application, leaving behind the beneficial properties of other ingredients without a heavy residue.

Cyclohexasiloxanes are also utilized in industrial applications, such as in the production of sealants and lubricants. Their chemical stability and inertness make them suitable for use in environments where other substances might degrade. Due to their widespread use, there has been scientific interest and regulatory scrutiny regarding their environmental persistence and potential bioaccumulation. Research continues to explore their behavior and impact in various environmental compartments.
