- Definition
Dimethicone is a mixture of fully methylated linear siloxane polymers containing repeating units of the formula: [–(CH₃)₂SiO–]ₙ stabilized with trimethylsiloxy end-blocking units of the formula: [(CH₃)₃SiO–] wherein n has an average value such that the corresponding nominal viscosity is in a discrete range between 20 and 30,000 centistokes. It contains not less than 97.0% and not more than 103.0% of polydimethylsiloxane ([–(CH₃)₂SiO–]ₙ). The requirements for viscosity, specific gravity, refractive index, and loss on heating differ for the several types of Dimethicone, as set forth in Table 1.
