Abstract
Abstract Water-in-oil compositions having a continuous oil phase comprising a silicone and a hydrocarbon cleaning component, a discontinuous water phase, comprise as emulsifier an organopolysiloxane of the formula Z(Me).sub.2 SiO[(Me).sub.2 SiO].sub.x [(Me)(R)SiO].sub.y [(Me)(QR')SiO] z --Si(Me 2 )Z where Me denotes methyl, Q a polyoxyalkylene radical, R a C 6 -C 16 alkyl radical, R' an alkylene and Z a monovalent radical. The organopolysiloxane allows stability and easy emulsification of water into an oil phase comprising those silicones and hydrocarbons which are preferred in polishes.

Claim 1
Independent Claim
321 words
A polish composition in the form of a water-in-oil emulstion comprising (1) 30 to 85 percent by weight of a discontinuous phase comprising water, (2) 0.2 to 10 percent by weight of a polydiorganosiloxane-polyoxyalkylene copolymer having the formula --Z(Me)2SiO{(Me)2SiO}x{(Me)(R)SiO}y{(Me)(QR')SiO}zSi(Me)2Z-- wherein Me denotes a CH3-- radical, Q denotes a polyoxyalkylene radical having the formula -- (OCH2CH2)p(OCHCH3CH2)qOR", R denotes an alkyl radical having from 6 to 16 carbon atoms, R' denotes an alkylene radical linking Q to the silicon atom, R" is selected from a hydrogen atom and an alkyl radical having from 1 to 4 inclusive carbon atoms, Z denotes a monovalent radical selected from the group consisting of hydrocarbon radicals having from 1 to 16 carbon atoms and QR'--radicals, there being an average of at least one QR'--radical and at least one R radical per molecule and the average values of x, y, z, p and q being such that p≧q, p+q has a value sufficient to provide a radical weight for Q of from 600 to 3500, x<3y, x+y+z has a value of from 30 to 400 and the total weight of Q radicals in the polydiorganosiloxane-polyoxyalkylene copolymer does not exceed a value of about 1/3 of the total weight of the polydiorganosiloxane-polyoxyalkylene cpolymer and (3), a continuous phase comprising (a) 1 to 15 percent by weight of a silicone component, which is a substantially linear polydiorganosiloxane represented by the formula ##STR5## wherein R3 and R4 groups are selected from methyl radicals, alkoxy radicals, alkoxyalkoxy radicals, hydroxy radicals and alkyl radicals, having as substituents attached thereto, at least one group selected from amino and amine salt groups, at least 50% of the total number of the groups being methyl radicals, and m has a value of from 20 to 2000, and (b) 0.5 to 40 parts by weight of a hydrocarbon component with a boiling point between 80° and 250° C., the weight percents being based on the total composition.
