Abstract: Foam control agents for inclusion in detergent compositions in powder form, are particulate and comprise a silicone antifoam compound and an organic material which is a fatty acid or a fatty alcohol, having 12 to 20 carbon atoms, or a mixture thereof and which has a melting point in the range 45.degree. to 80.degree. C. and is insoluble in water. The foam control agents are made by a process in which the antifoam and the organic material are contacted in their liquid phase. These foam control agents give a good storage stability in the detergent powders.

Abstract: Siloxane-polyester compositions comprising (1) a siloxane-polyester copolymer resin (2) a silane wherein one of the groups attached to silicon is an organic group containing at least one amino group, the remaining valencies of the silicon being satisfied by alkoxy, alkoxyalkoxy, methyl or phenyl groups there being present at least two alkoxy or alkoxyalkoxy groups, (3) a solvent for the siloxane-polyester copolymer and (4) a titanium chelate.The presence of (2) and (4) improves the rate of cure of the siloxane-polyester, and the compositions are useful for providing decorative and protective coatings on metals, plastics and other substrates.

Abstract: Composition comprising (A) a polydiorganosiloxane having molecular weight of at least 2500 and terminal --OX groups in which X is hydrogen, lower alkyl or alkoxyalkyl, at least two of the substituents in the polydiorganosiloxane containing at least two amine groups, the remainder preferably being methyl radicals, and (B) an organosiloxane having at least 3 silicon-bonded hydrogen atoms. The compositions can be applied to keratinous fibres to render such fibres shrink resistant and are particularly suitable for application in the form of an aqueous emulsion.
