Hair care compositions contain from 0.1 to 12 weight percent of a silicone copolymer or saponification product thereof, prepared from silicones, at least 10% of which contain polymerizable groups, 0.5-14% of hydrophilic comonomers, and 30-99.9% of hydrophobic comonomers. The compositions exhibit good hair care properties.

Hair care composition

The invention provides a chewing gum base containing a homogeneous composition in solid form comprising

Solid homogeneous mixture of polyvinylacetate and vinylacetate-vinyl laurate copolymer prepared by sequential solution polymerization

The invention provides homogeneous compositions in solid form comprising

Solid homogenous mixtures of polyvinylacetate and vinylacetate-vinyl laurate copolymer prepared by sequential solution polymerization

Silane-modified polyvinyl acetals are obtained by copolymerizing a) vinyl esters of C alkylcarboxylic acids having from 1 to 15 carbon atoms, and optionally (meth)acrylates C of alcohols, olefins, dienes, vinylaromatics, or vinyl halides, with b) from 0.02 to 20.0 % by weight of an ethylenically unsaturated, hydrolyzable silicon compounds or hydrolyzable mercaptosilanes; hydrolyzing the resulting vinyl ester copolymers to 50 mol % or more of vinyl alcohol units; and acetalizing vinyl alcohol units with a C aliphatic or aromatic aldehydes, wherein from 5 to 50 % by weight of a mixture of comonomers a) and silane comonomers b), based on the total weight of comonomers a) and b), is used as an initial charge, and the remainder is metered in during polymerization, such that the ratio between the comonomers a) and silane comonomers b) remains constant throughout the polymerization, resulting in a homogeneous polymer.
