摘要:
Compositions comprising a powder and an alkyl-phenyl silsesquioxane resin are disclosed. These compositions are particularly useful in a variety of personal or medical care compositions to enhance the durability and substantivity of powders after topical application.
摘要:
MQ-T propyl siloxane resins comprising (R13SiO1/2)a, (R22SiO2/2)b, (R3SiO3/2)c, and (SiO4/2)d units, where at least 40 mole % of the R3 groups are propyl are disclosed. A method of preparing such siloxane resins by reacting a MQ siloxane resin with a T propyl siloxane resin is also disclosed. These siloxane resins are useful in a variety of personal, household, and medical care applications, and in particular, as a resin additive in pigmented cosmetic formulations.

摘要:
A composition for rendering surfaces water repellent is formed by combining water or a solvent; a methylhydrogensiloxane polymer or copolymer; an alkoxysilane having the formula RaSi(OR′)4−a in which R represents an alkyl group containing 1-10 carbon atoms, an alkenyl group containing 2-8 carbon atoms, an aryl group, or an haloalkyl group, a has a value of 1 or 2, and R′ represents an alkyl group containing 1-6 carbon atoms; and a silicone resin. The composition can also contain other components such as a volatile methyl siloxane, a cationic oil-in-water emulsion of an aminofunctional polydimethylsiloxane, a surfactant, a catalyst, a beading agent, an organic wax, a preservative, an antifoam, a mildewcide, an UV absorber/UV light stabilizer, or a freeze-thaw additive.
