Tetradecamethylcycloheptasiloxane

Tetradecamethylcycloheptasiloxane (CAS 107-50-6), commercially known as Cyclomethicone 7, is a cyclic siloxane used across personal care, industrial coatings, and automotive applications. It functions as a lubricant, foam suppressant, and surface modifier.

This chemical delivers low surface energy and controlled slip to finished formulations. In personal care, it acts as a carrier and skin-feel modifier in silicone-based emollients, hair serums, and antiperspirant sticks where a dry finish is required.

Automotive and industrial lubricant formulators incorporate it to reduce friction and improve surface release in precision components and mold-release systems. It is highly valued for its ability to provide a non-greasy application.

In coatings and sealant systems, it contributes to substrate wetting and surface leveling, improving adhesion and film uniformity. This ensures a high-quality finish across various industrial and commercial surface applications.

Foam control applications in industrial processing benefit from its ability to destabilize surface foam without contaminating the bulk phase. This makes it an efficient additive for maintaining process stability in chemical manufacturing.

Tetradecamethylcycloheptasiloxane is supplied as a clear, low-viscosity liquid. It is available in technical and cosmetic grades, with cosmetic-grade material meeting purity standards relevant to personal care formulation requirements.

Bulk supply is standard in drum and IBC quantities, with smaller packaging available for specialty formulation use. Our logistics network ensures reliable delivery for large-scale industrial operations and specialized laboratory needs.
