  • Mixtures of volatile linear siloxanes
    Patent number: 6350440
    Abstract: The invention relates to mixtures of linear organosiloxanes of the general formula 1 R3SiO—(SiR2O)n—SiR3  (1), where R can be identical or different and is a hydrocarbon radical having from 1 to 18 carbon atoms which is optionally substituted by fluorine, chlorine or cyano radicals and is free from ethylenically or acetylenically unsaturated bonds, and n has values from 0 to 20, where the mean number of carbon atoms of the radicals R is at most 3 and where the mixtures have evaporated, measured in accordance with DIN 53249, to an extent of from 80 to 95% by weight after 30 minutes, to an extent of from 90 to 99% by weight after 60 minutes and to an extent of from 95 to 100% by weight after 120 minutes. The mixtures of linear organosiloxanes are added to cosmetic formulations.
