1,223,250. Two-component packs for hair treatment. L'OREAL. 19 April, 1967 [19 April, 1966], No. 2326/70. Divided out of 1,197,031. Addition to 1,197,037. Heading DIP. A two-component pack for use in the treatment of hair comprises, as the first component, a methylolated compound which is monomethylol dicyandiamide, bis-methoxymethyl urea, monomethylol dimethylhydantoin, monomethylol ethyleneurea, monomethylol ethylene thiourea, dimethylol ethylene thiourea. monomethylol guanidine, monomethylol ethyl carbamate. N, N'-dimethylol (2-methyl- 2-propyl) propylene bis-carbamate, dimethylol ethyl methylene-bis-carbamate, dimethylol succinamide, dimethylol adipamide. N, N-diethyl-N'-methylol urea, dimethylol ethylene urea, dimethylol ethyl carbamate or tetramethylol acetylene diurea in the solid state, and, as the second component, an acid polymerisation catalyst, either or both of these components containing a solution a nitrogencontaining compound which is urea, melamine, dicyandiamide, N, N-diethyl urea, ethylene urea, isopropyl carbamate, dimethyl hydantoin, ethylene thiourea, guanidine carbamate or succinamide, or comprises, as the first component, a methylolated compound which is monomethylol urea, dimethylol urea, monomethylol thiourea, dimethylol thiourea or trimethylol melamine in the solid state, and, as the second component, an acid polymerisation catalyst, either or both of these components containing a solution of a nitrogen-containing compound which is N, N-diethylurea, ethylene urea. isopropyl carbamate, dimethyl hydantoin. ethylene thiourea or succinamide, the relative proportions of the active ingredients in the components being such that on mixing the entire contents of the two components a composition containing 0.5-12% by weight of the methylolated compound is obtained. The number of amino groups provided by the nitrogen containing compound may be 0.1-1 times the number of methylolated groups provided by the methylolated compound. The amount of acid polymerisation catalyst, e.g. acetic, citric, lactic, phosphoric or sulphuric acid or sodium acid phosphates, may be such that the resulting composition has a # H of 1.5-3. The resulting composition may be in the form of a hair setting lotion. |
