1. A composition comprising a dispersion comprising:
(a) a polyorganosiloxane comprising at least 90 mole-percent dimethyl D units and having a viscosity of one kilopascal*second or more at 25 degrees Celsius, the polyorganosiloxane being in the form of particles having an average size of 0.5 to 20 micrometers;
(b) a condensation product of:
(i) a polysiloxane resin having a weight-average molecular weight of 4,000-50,000 and having the following composition:
(R3SiO1/2)a(SiO4/2)b(ZO1/2)c
where subscripts a, b and c are molar equivalents of the associated molecular unit, a is 0.30-0.60, subscript b is 0.40-0.70, subscript c is 0.05-0.20, the sum of subscripts a and b is one, R is independently in each occurrence selected from a group consisting of hydrogen, C1-30 alkyl groups and aryl groups, and Z is independently in each occurrence selected from a group consisting of H, and C1-C8 alkyls; and
(ii) a polyoxyalkylene polymer having a number average molecular weight of 4,500 Daltons or more and at the same time 50,000 Daltons or less and having the following composition:
A—O—(C2H4O)e(C3H6O)p—A′
where the ratio e/p is greater than one and less than 9, A and A′ are independently selected from a group consisting of hydrogen, alkyl, substituted alkyl, aryl, and substituted aryl groups provided that at least one of A and A′ is H;
(c) a non-aqueous fluid carrier that is miscible with the polyoxyalkylene polymer; and
(d) a monoterpene;
wherein the weight-ratio of non-aqueous fluid carrier (c) to condensation product (b) is 0.5 or more and 10 or less; the weight-ratio of the combination of condensation product (b) and non-aqueous fluid carrier (c) to polyorganosiloxane (a) is 0.01 or more and 0.50 or less; and the composition contains less than one weight-part aromatic solvent per million weight parts composition.
