    Abstract: Cosmetic composition for use in treating damaged hair. The composition comprises, as the active component a methylol compound of the formula:

    IN A SUITABLE COSMETIC CARRIER, IN WHICH FORMULA: X represents either an oxygen atom or a sulfur atom or an NH group; R and R'' are identical or different and represent either a hydrogen atom or a lower alkyl radical; and R1 and R2 represent either a methyl hydroxy group or a methyl alkoxy group, e.g. methyl alkoxy wherein the alkoxy contains up to five carbon atoms or more. Typically the methylol compound is N,N''-dihydroxymethyl glyoxalurea or N,N''-dihydroxymethyl glyoxalthiourea. The composition is applied at an acid pH and is advantageously made up in solid form for mixing with water or water-and-alcohol solutions when used. The compositions are used by impregnating the hair with a mixture thereof and water or water-and-alcohol solution followed by drying with heat.

    Abstract: 1279144 Neutralising composition L'OREAL 25 July 1969 [25 July 1968 9 July 1969] 37617/69 Heading DIP The active ingredient in a neutraliser for hair waving compositions comprises in an amount of from 0.5 to 12% by wt a compound of the general formula: in which R represents H or a 1-6C alkyl radical, Y represents a -#C-, -#C-, -#CO S NH or -SO 2 - radical or Y represents a -#CN radical which together with R" forms a ring compound which may contain other -#N-CH 2 OR groups, R' represents H, alkyl, R' hydroxymethyl or alkoxymethyl, and R" represents (i) a hydrogen atom (ii) an alkyl or alkoxy radical which may contain an amido or carbamate group, which may be substituted with a methylol radical (iii) an amino group which may be substituted with an alkyl, cyano, or -CH 2 OR radical (iv) or an aryl or alkylaryl radical; or R' and R" may form a ring which may contain other hetero-atoms and/or other -Y-#N-CH 2 OR groups or dimethylol #R' -methylene-bis-(ethylcarbamate). Suitable ingredients of this formula are dimethylolethyleneurea, dimethylolethylenethiourea, trimethylolmelamine, dimethylolurea, N, N'-dimethylol-(2-methyl-2-propyl) propylenebis-carbamate, dimethylol-succinamide, dimethyloladipamide, dimethylol (ethylcarbamate), monomethylolurea, monomethylolthiourea, monomethyloldimethylhydantoin, monomethylolethyleneurea, monomethylolethylenethiourea, monomethyloldicyandiamide, monomethylolguanidine, monomethylol (ethylcarbamate), monomethyloldiethylurea, and N, N'-dihydroxyethyldihydroxyethyleneurea. The active ingredient may be included in a composition having a pH of from 1.5 to 6 or in the case of dimethylolthiourea a pH of from 8.5 to 10. The composition may also include an oxidising agent e.g. hydrogen peroxide, urea, peroxide, sodium perborate, ammonium persulphate, sodium peroxycarbonate, sodium bromate or potassium chlorate wherein the molar ratio of oxidising agent to active ingredient is from 0.1:1 to 10:1. The composition may also contain conventional neutraliser additives such as cationic compounds, resins e.g. vinyl acetate/ vinyl pyrrolidone copolymer or silicone oil, dyestuffs, perfumes, surface active agents, penetrating agents or peptising agents. The composition may take the form of a cream, gel or aerosol or may be in the form of an aqueous or aqueous-alcoholic solution, it may also be in the form of a two-component pack - the first component comprising an active ingredient of the above general formula and the second comprising an oxidising agent. Hair may be treated by first reducing it, then winding it on rollers, and after impregnation with the composition of the invention drying it before rinsing the composition off. Hair may be impregnated before constraining on rollers.
