CYCLOHEXASILOXANE

CAS Number	540-97-6
Chem/IUPAC Name:	Dodecamethylcyclohexasiloxane
EINECS/ELINCS No:	208-762-8
COSING REF No:	75406

Cyclohexasiloxane is a silicone-based compound frequently used in cosmetics and personal care products. This clear, odorless liquid acts as a lightweight and volatile carrier ingredient that imparts a silky, non-greasy feel to skincare and haircare formulations. It enhances product spreadability, aids in quick absorption, and provides a smooth, matte finish. Cyclohexasiloxane is often utilized alongside other silicones like cyclopentasiloxane to improve the overall texture and performance of cosmetic products. While cyclopentasiloxane is also commonly used, the choice between the two depends on the specific formulation and desired properties, making them valuable tools in cosmetic science. The chemical formula of Cyclohexasiloxane is C₁₂H₃₆O₆Si₆.

What is CYCLOHEXASILOXANE used for?

Cyclohexasiloxane is a versatile ingredient and is commonly used in personal care products due to its unique properties.

Skin care: It serves as an excellent carrier for other active ingredients in a formulation, aiding in their penetration into the skin. Its lightweight and non-comedogenic nature makes it ideal for moisturizers, serums, and sunscreens, providing a silky, smooth texture without clogging pores. By creating a breathable barrier on the skin's surface, Cyclohexasiloxane helps in reducing water loss, enhancing hydration, and promoting a soft, supple complexion
Hair care: It contributes to smoother and more manageable hair. It is commonly found in hair serums and conditioners, where it helps detangle and reduce frizz, resulting in silky, lustrous locks. Due to its low viscosity, it spreads easily through the hair without leaving a heavy or greasy residue. It also provides heat protection, making it beneficial for use with styling tools, such as flat irons and hairdryers, while minimizing damage and maintaining a sleek, polished appearance

Origin

Cyclohexasiloxane is synthetically produced through a chemical process known as cyclotetramerization, where the precursor compound is subjected to high temperatures and catalysts to form the cyclic structure. This process involves the controlled arrangement of silicon and oxygen atoms to create the cyclohexasiloxane molecule (D6). The resulting clear, volatile liquid is then purified for use in cosmetics.

Safety profile

Cyclohexasiloxane is considered safe for cosmetic use when used as directed. It has a low potential for skin irritation and is non-comedogenic, making it suitable for most skin types. However, like many cosmetic ingredients, some individuals with hypersensitive skin may experience mild irritation. A patch test is recommended prior to full application.
