Claim Text:
1. An external-surfactant-free water-in-oil invert emulsion, comprising: A) from 5 to 95 parts by weight of one or more self-emulsifying organopolysiloxanes of the formulae (i) and (ii): where a is at least 3, b is 0-4, and c is 0-2; where M is a monovalent siloxy unit of the formula where e, f, g, and h are individually integers from 0 to 3 and the sum (e+f+g+h) equals 3; R is a lower alkyl group or an aryl group, R R R where T is a trivalent siloxy unit of the formula where the sum (e′+f′+g′+h′) is 1; where Q units are of the formula SiO and the liquid, branched organopolysiloxane contains at least one of each of R wherein R′ is a group L or a C R J is an aralkyl group; K is a long chain C L is an Si—C bonded, oxygen-containing hydrophilic group having a molecular weight greater than 100 Daltons; w is from 0 to 200; x is from 1-100; y is from 1 to 50; and z is from 1 to 50, containing less than 5 mol percent, based on the total mols of w,x,y, and z, of R′SiO B) water.
