DISILOXANE

CAS Number 107-46-0
Chem/IUPAC Name: Bis(trimethylsyl)Oxide
EINECS/ELINCS No: 203-492-7
COSING REF No: 55874
DISILOXANE
Disiloxane is a type of silicone compound that is primarily used in cosmetic formulations as a solvent, providing a lightweight and silky texture to products. It helps to improve the spreadability of creams, lotions, and serums, allowing for smooth and even application on the skin. Due to its volatility, Disiloxane evaporates quickly upon application, leaving behind a soft and non-greasy feel. Its properties make it a popular choice in various skincare and haircare products. In its raw form, this ingredient appears as a clear and odorless liquid. The chemical formula of Disiloxane is H6OSi2.

What is DISILOXANE used for?

Disiloxane finds multiple uses in the realm of cosmetics, with distinct benefits for the skin, hair, and overall product formulation.
  • Skin care: It is often employed as a solvent and carrier for active ingredients. Its lightweight texture allows for easy application, helping serums, creams, and lotions spread smoothly across the skin. Disiloxane's rapid evaporation rate ensures quick absorption, leaving the skin feeling soft and non-greasy. Additionally, its presence can contribute to the formulation's overall stability and longevity
  • Hair care: It enhances the spreadability of hair products such as leave-in conditioners, hair serums, and styling products, allowing for even distribution. The lightweight nature of disiloxane helps reduce product build-up and heaviness, resulting in hair that feels weightless, silky, and manageable
  • Cosmetic products: It aids in dissolving and dispersing pigments, oils, and other components, ensuring a homogeneous and well-blended product. Disiloxane's quick evaporation rate also assists in achieving desirable product textures, such as lightweight foundations or primers, without leaving a heavy residue on the skin

Origin

Disiloxane is typically synthesized through the hydrolysis and condensation reactions of organosilicon compounds. It involves combining silane precursors, such as alkylchlorosilanes or alkyltrichlorosilanes, with water or alcohol. This process results in the formation of disiloxane molecules, which can then be purified and used in cosmetic formulations.

Safety profile

Disiloxane is generally considered safe for use in cosmetics, as it has been assessed by regulatory authorities and deemed suitable for formulation. However, like any cosmetic ingredient, individual sensitivities may vary. It is advisable to perform a patch test before using products containing disiloxane, especially if you have known sensitivities or allergies. Additionally, Disiloxane is a non-comedogenic and vegan-friendly ingredient.
