Tetradecamethylcycloheptasiloxane

Tetradecamethylcycloheptasiloxane (CAS 107-50-6), commercially known as Cyclomethicone 7, is a cyclic siloxane.

Where is Tetradecamethylcycloheptasiloxane used?

• Personal care: carrier and skin-feel modifier in silicone-based emollients, hair serums and antiperspirant sticks for a dry finish
• Coatings and sealants: substrate wetting and surface leveling for adhesion and film uniformity
• Industrial processing: foam control that destabilizes surface foam without contaminating the bulk phase
• Automotive and industrial lubricants: friction reduction and surface release in precision components and mold-release systems
• It functions as a lubricant, foam suppressant and surface modifier.

Good to know: Cosmetic-grade material meets purity standards relevant to personal care formulation.

Commercial specifications

• Bulk supply in drum and IBC quantities; smaller packaging for specialty formulation
