Usage Method

XIAMETER PMX-0246 Cyclohexasiloxane may be used alone or blended with other cosmetic fluids to provide a fluid base for a variety of cosmetic ingredients.

It features good solubility in most anhydrous alcohols and in many cosmetic solvents.

XIAMETER PMX-0246 Cyclohexasiloxane is a volatile fluid with appreciable vapor pressure at ambient temperature.

Note that the pentamer component (D5) evaporates at a faster rate than the hexamer component (D6).

By using blends of cyclomethicones this difference in volatility can be used to vary the residence time of the silicone on the skin.

Unlike other volatile carriers used in the personal care industry, volatile silicone fluids do not cool the skin when they evaporate. This is a consequence of their unusually low heat of vaporization.

Table 1 gives the heat required to vaporize one gram of each of the indicated materials.
