Octamethyltrisiloxane

Octamethyltrisiloxane (CAS 107-51-7) is a low-viscosity linear silicone fluid used as a carrier solvent, surface modifier, and lubricant across personal care, textile, and industrial applications. Its silicone backbone delivers exceptional spreadability and surface wetting without leaving heavy residues. This makes it a preferred base fluid where clean, fast-evaporating delivery is required for high-performance products.

In personal care formulations, it functions as a lightweight carrier for active ingredients in skin serums and hair conditioning products. It also improves spreadability and skin feel in antiperspirants and cosmetic blends. Textile and leather finishing operations use it to impart softness, water repellency, and surface slip to treated substrates. It provides a smooth finish while maintaining the integrity of the underlying material.

In metalworking and automotive lubricant formulations, it serves as a base fluid or co-solvent. It is valued where thermal stability and low surface tension are required for consistent film formation on metal parts. It also supports emulsification and dispersion processes where silicone-based wetting agents are needed. These agents stabilize formulations or improve substrate penetration in complex chemical mixtures and industrial coatings.

The product is supplied as a clear, low-viscosity liquid available in technical and cosmetic grades. Cosmetic-grade material meets purity standards relevant to personal care applications and sensitive formulations. Packaging typically ranges from drums to IBC containers, with bulk supply available for industrial volumes. This ensures flexible logistics for both small-scale manufacturing and large-scale chemical processing plants.
