Abstract
A new composition of matter is a blend of (i) a crosslinked elastomeric silicone polyether and (ii) a crosslinked elastomeric silicone containing alkyl groups having 3-40 carbon atoms. The new composition can be used in preparing water-in-oil emulsions, and clear solutions containing an oil(s) or an oil-soluble active ingredient(s).
Claims18
A composition of matter comprising a blend of (i) a crosslinked elastomeric silicone polyether, and (ii) a crosslinked elastomeric silicone containing alkyl groups having 16 to 30 carbon atoms, the crosslinked elastomeric silicone polyether and the crosslinked elastomeric silicone containing alkyl groups having 3-40 carbon atoms being present in the blend in a weight ratio of 4:1 to 1:8.
A composition of matter comprising a blend of (i) a linear silicone polyether, and (ii) a crosslinked elastomeric silicone containing alkyl groups having 3-40 carbon atoms, the linear silicone polyether (i) and the alpha, omega-diene crosslinked elastomeric silicone (ii) being present in the blend in a weight ratio of 4:1 to 1:8.
