Dodecamethylcyclohexasiloxane(CAT: R051604), commonly abbreviated as D6, is a cyclic siloxane composed of six repeating dimethylsiloxane units. It is a clear, low-viscosity liquid widely used in personal care and cosmetic formulations for its excellent spreading properties, smooth skin feel, and quick evaporation. D6 serves as a volatile carrier fluid in antiperspirants, hair products, and skin treatments. In industrial applications, it is employed as an intermediate in silicone polymer synthesis and surface treatment agents. Its thermal stability, low surface tension, and compatibility with various materials make it valuable in both consumer and technical applications involving silicones and performance materials.
