Cyclohexasiloxane is a non-crystalline, colorless liquid with a sweet faint odor. It evaporates completely at room temperature. Cyclohexasiloxane has high stability and excellent oxidative resistance.

The production process involves the preparation of cyclic silicones by reacting hexamethyldisiloxane with 1,3-cyclohexanedione to form cyclohexasiloxane.

It provides a soft and silky feel to the skin, is dry and non-greasy, and has good spreading properties. It can be used as a volatile carrier. It is compatible with a wide range of cosmetic costs. It has a very low surface force.

Cyclotetrasiloxane is, in general, made by condensation of siloxane with ethylene oxide in the presence of titanium tetra alkyl titanate catalyst. 


Cyclohexasiloxane is widely used in sun protection, color cosmetics, skincare, deodorant and antiperspirant, hair conditioning and other products.

Apart from being used in cosmetics, it is also used in making electronic devices and lubricants. This product can be used directly as a carrier, the main raw material, or as an additive and can also be used in aqueous systems using emulsification.

It can be used as an additive in perfumes and cosmetics. This material is used as a solvent in silicone polymerization, as a pharmaceutical excipient, as an intermediate in organic synthesis, and as a component of hydraulic fluids.

Cyclotetrasiloxane is used in hair care products to make hair soft and shiny, make hair silky, and make hair smooth. Cyclotetrasiloxane is used in hand sanitizers to make it smooth, clear and prevent the lotion from evaporating quickly.
