Definitions

• ABSTRACT A composition for dyeing keratinic fibers and particularly human hair which comprises, in aqueous solution, at least one direct dye having a poor affinity for the fiber at room temperature and an organic solvent which is inert to both the dye and the fiber. and corresponds to the formula DYEING KERATINIC FIBERS WITH AQUEOUS SOLUTIONS OF DIRECT DYES AND ORGANIC SOLVENTS
• This invention relates to a new process for dyeing animal fibers, and especially living or dead hair, and to a composition for carrying out that process.
• the process according to the invention makes it possible to substantially broaden the range of colorants which may be used, especially for dyeing hair, as a consequence of the fact that it assists and accelerates the coloration of the hair and the fixing of the dye while operating at the ambient temperature or at a moderate temperature (below 50 C.).
• the invention also permits satisfactory coloring effects to be produced with dyes which do not, at the above temperatures, have any great affinity for the hair, and this is a very important practical advantage.
• R represents an aliphatic hydrocarbon which may or may not have a branched chain and comprises at most eight carbon atoms
• n is a number between one and four inclusive.
• thioether alcohol such as thiodiglycol
• a ketoalcohol such, for example, as diacetone alcohol (up to 10 percent),
• An aromatic alcohol such as benzyl alcohol (up to 4 percent) or beta-phenylethyl alcohol (up to 1 percent),
• An alicyclic alcohol which may be homocyclic, such as cyclohexanol (up to 3 percent) or heterocyclic, such as furfuryl alcohol,
• organic solvents to which the present invention is directed act in the same way as those described in said prior patents so as to materially strengthen the coloring of the hair and assist in fixing of the dyes on the hair, either at room temperatures, or at the temperatures hereinbefore specified. They may be used as components of mixtures including the solvents described in the above two patents.
• R represents an alkyl radical which may have either a straight or branched chain and comprises three to eight carbon atoms, or phenyl (C H or benzyl (C6H5-CH2) or cyc1ohexyl(C H n is a number between one and four inclusive.
• Specific exemplary solvents of the above class are 3- amyloxyl,2-propanediol; 3-benzyloxy-l,2-propanediol and 3-phenoxyl ,2-propanediol.
• direct dyes is used to indicate any coloring substance capable of being fixed directly in its final color by the product being dyed, without requiring any additional chemical change such as oxidation, coupling,
• the direct dyes may be selected from among the types of dyes described in said prior patents, to wit:
• Nitro dyes which may be acid, slightly basic, or strongly basic, for example:
• ORASOL ClBA
• CFMC Color lndex, 2nd Ed, 1956, p.
• LANASYNE (SANDOZ) Color lndex, 2nd Ed, 1956,
• Acetoquinonc Light Red HZ (C.l. Disperse Red 17) Color index, 2nd Ed, 1956, Supplement. 1963.
• two or more such dyes may be associated in identical or different proportions, in the same dyeing solution, so as to produce various desired shades, and particularly the colors of natural hair.
• a composition for dyeing animal fibers at room temperature which comprises in aqueous solution at least one direct dye in amounts effective to dye said fibers and at least one organic solvent which is chemically inert with respect to said dye and the fiber which is to be colored, said solvent having the formula:
• R is selected from the group consisting of alkyl having three to eight carbon atoms, phenyl, benzyl, and cyclohexyl, and n is a number between one and four inclusive, and being present in amounts of 1-15 weight percent of said composition.
• said at least one direct dye is selected from the group consisting of nitro dyes, disperse dyes, solvent dyes, metallic dyes and basic dyes.
• said at least one direct dye is selected from the group consisting of nitro dyes, disperse dyes, solvent dyes, metallic dyes and basic dyes.
• said at least one direct dye is selected from the group consisting of a) a solvent having the formula R-(OCH,CH,),,OH wherein R represents alkyl having at most eight carbon atoms and n is a number between 1 and 4 inclusive, (b) butyl alcohol in amounts up to 5 weight percent of said composition, (c) thiodiglycol in amounts up to 10 weight percent of said composition, (d) diacetone alcohol in amounts up to 10 weight percent of said composition, (3) an aromatic alcohol selected from the group consisting of
• the method of dyeing hair which comprises the step of applying thereto an effective amount of a composition as claimed in claim 1, for a period of at least 15 minutes, and the rinsing and drying the hair.
