摘要:
Organopolysiloxane gels are prepared by reacting an unsaturated silicone resin, a minor proportion of a terminally unsaturated polyoxyalkylene polyether, and two Si—H-functional organopolysiloxanes, one (2) with from 0.011 to 0.044 wt. % of Si—H groups, and one (2′) with from 0.045 to 0.35 wt. % of Si—H groups, where the molar ratio of (2) to (2′) is from 0.2 to 20. Compositions containing the gels are storage stable, and can absorb polar and/or hydrophilic substances and yet form monoplastic mixtures. The gels are particularly useful in personal care compositions.
