D5 / D6 Cyclo-2345 Cyclomethicone Fluid

Cyclomethicone fluids are commonly used in personal care products due to their smooth feel, low surface tension, and quick evaporation. They work well as base fluids, carrying agents, and wetting agents in items like body sprays, skin creams, hair care products, and more.

A key benefit of Cyclomethicones is that they are exempt from VOC (Volatile Organic Compound) regulations, including California’s strict standards. This makes them an eco-friendly alternative to petroleum-based solvents, as they don’t contribute to ozone depletion or global warming.

Cyclo-2244 and Cyclo-2245 have similar evaporation rates to solvents like mineral spirits, while Cyclo-2345 offers a slower rate for specific needs. Cyclomethicones are also compatible with many materials, including metals and plastics, making them a versatile ingredient for various products.
