Abstract: 1,231,452. Hair lacquers. L'OREAL. 26 July, 1968 [28 July, 1967], No. 35899/68. Heading A5B. [Also in Divisions C3 and C4] A cosmetic composition suitable for use as a hair lacquer or wave-setting lotion comprises water and/or alcohol and at least one copolymer derived solely from at least one monomer for each of the following three groups: (1) an unsaturated ester of the formula: in which:  R represents a straight-chain alkyl radical of 1 to 4 carbon atoms;  n is 0 or 1; and R 1  represents a hydrogen atom or an alkyl radical of 1 to 5 carbon atoms or in which: R 2  and R' 2  represents a hydrogen atom or an alkyl radical of 1 to 5 carbon atoms; R 3  represents the radical -COOR 4  or the radical: in which:  R 4  represents a straight-chain alkyl radical of 1 to 8 carbon atoms; and Y represents a hydrocarbon radical of 1 to 10 carbon atoms, optionally containing chain hetero groups of formula -O-, -S- or -NH-, or a single bond when R 2  is other than hydrogen or R' 2  is other than hydrogen or a methyl group. (2) an unsaturated acid of the formula: in which: R 5  and R' 5  represents a hydrogen atom or an alkyl radical of 1 to 5 carbon atoms; R 6  represents the radical -COOH or the radical: and X represents a hydrocarbon radical of 1 to 10 carbon atoms, optionally containing chain heterogroups of formula: -O-, -S-, or -NH-, or a single bond when R' 5  is other than hydrogen or a methyl group. (3) an unsaturated ester of the formula: in which: R; represents a linear or branched, saturated or unsaturated hydrocarbon radical of 8 to 22 carbon atoms; R 8  represents a hydrogen atom or an alkyl radical of 1 to 5 carbon atoms; and m is 0 or 1, or in which: R 9  and R' 9  represents a hydrogen atom or an alkyl radical of 1 to 5 carbon atoms; R 10  represents the radical -COOR 11  or the radical: in which: R 11  represents a hydrocarbon radical of 8 to 18 carbon atoms or a lanolinyl radical; and Z represents a hydrocarbon radical of 1 to 10 carbon atoms, optionally containing chain heterogroups of formula -O-, -S- and -NH-, or represents a single bond when R 9  is other than hydrogen or R' 9  is other than hydrogen or a methyl group, or e) an unsaturated ether of the formula: in which: R 13  represents a linear or branched, saturated or unsaturated hydrocarbon radical of 12 to 18 carbon atoms, optionally substituted by hydroxy or alkoxy groups and/or contains chain heterogroups of formula: R 12  represents a hydrogen atom or an alkyl radical or 1 to 5 carbon atoms; and p is 0 or 1, or f) an olefine of the formula: in which:  R 14  represents a linear alkyl radical of 4 to 18 carbon atoms. The compositions of Specification 1,153,544 are disclaimed. Preferred copolymers are those claimed in Specifications 1,231,453 & 1,231,454 (Division C3) and the copolymer is preferably neutralised with an organic base. The copolymer is used as a hair laquer or rare-setting lotion in water and/or an alcohol or in an aerosol using a fluorocarbon propellant. Optional additives are perfume, quaternary ammonium compounds, butyl myristate, urea or silicones. The following monomers are used in the examples: (1) vinyl acetate, vinyl propionate and allyl acetate, (2) 4-pentenoic acid, 3-butenoic acid, crotonic acid, allyloxyacetic acid, allyloxypropionic acid, and 1-pentenoic acid, (3) allyl stearate, vinyl laurate, stearyl vinyl ether, crotyl laurate, lanolin crotonate, 1- octene, 1-hexadecene allyl oleate, oleyl crotonate, 1-allyloxy-3-dodecylthio-propanol-2, 1- allyloxy-3-dodecyloxyl-propanol-2, vinyl octanoate, vinyl stearate, allyl laurate. They may be neutralised with diisopropylamine, triethanolamine, 2-amino-2-methyl-propanediol-1, 3 or aminoethylpropanediol.
