Cyclohexasiloxane — D6 / CAS 540-97-6

Description

1. Product Overview

Cyclohexasiloxane (D6), also known as Dodecamethylcyclohexasiloxane, is a high-performance cyclic silicone fluid widely used as a specialty ingredient in personal care, cosmetics, industrial formulations, and silicone manufacturing. Its excellent thermal stability, low surface tension, and volatility profile make it valuable for applications requiring smooth texture, fast evaporation, and superior spreading properties. D6 serves as a critical raw material for advanced silicone-based products, supporting global demand for high-quality elastomer, lubricant, and cosmetic formulation systems. Its consistent performance and compatibility with silicone technologies make it a strategically important material across multiple industrial sectors.
