Methods and compositions for preventing or reducing hair frizz. The compositions are preferably oil-in-water or water-in-oil emulsions comprise at least one polysiloxane fluid component selected from an amodimethicone and a polysiloxane component comprising a plurality of hindered amine side chains. The compositions also comprise a silicone-compatible, volatile or non-volatile liquid carrier component, preferably comprising a component selected from a low molecular weight, volatile siloxy component; a hydrocarbon; and an alcohol. The compositions are preferably combing cremes, sprays or mousses, and are suitable for use a “leave-in” hair care product, or as a touch-up hair care product suitable for use during the day.

The invention relates to a bi-functionalized polysiloxane brush copolymer comprising at least one hydroxyl-terminated polyalkyleneglycol side chain and at least one onium-functionalized side chain as defined herein, and a method for preparing the bi-functionalized polysiloxane brush copolymer, a curable composition comprising the bi-functionalized polysiloxane brush copolymer and its use.

The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves heating a silicone hydrogel contact lens in an aqueous solution in the presence of a watersoluble, highly branched, thermally-crosslinkable hydrophilic polymeric material having positively-charged azetidinium groups, to and at a temperature from about 40° C. to about 140° C. for a period of time sufficient to covalently attach the thermally-crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one azetidinium group and one of the reactive functional groups on and/or near the surface of the silicone hydrogel contact lens, thereby forming a crosslinked hydrophilic coating on the silicone hydrogel contact lens. Such method can be advantageously implemented directly in a sealed lens package during autoclave.
