Definitions
- a composition for bleaching keratinic fibers includes a mixture of an oxidizing agent and at least one N- methylol compound which is methylated on the nitrogen of a group or a derivative thereof.
- the oxidizing agent is mixed with the N-methylol compound or its derivative just before application of the resulting mixture to the keratinic fibers.
- This invention relates to a novel composition for the hot decoloration of human keratinic fibers.
- oxidizing compositions for decoloration of the hair have been known and such compositions employed, as the oxidizing agent, such materials as per salts, and peroxides including hydrogen peroxide.
- Such compositions were generally in the form of a cream or gel.
- These known compositions were usually applied to the fibers that were to be bleached for a suflicient period of time, generally in the order of several minutes.
- the decoloration composition of the present invention also provides strengthening of the hair which, as is known, generally becomes rather pronouncedly degraded by the action of the conventional oxidizing agents.
- the novel compositions offer the special characteristic of releasing a certain amount of nascent sulfur which improves the ultimate appearance of the hair by eliminating or substantially reducing an undesirable oily or greasy appearance or condition of the hair.
- compositions of the present invention can provide simultaneous acceleration of the bleaching action, restoration or strengthening of the hair which has undergone degradation in the oxidation reaction to decolor or bleach the same, or which has been degraded by prior treatment, and in certain instances an elimination or substantial reduction of a greasy appearance or condition of the hair.
- the novel composition of this invention comprises a mixture of an oxidizing agent and at least one N-methylol compound, the methylol being on the nitrogen of a group, or a derivative of such a compound.
- the N- methylol compound is admixed with the oxidizing agent immediately before its use.
- N-methylol compounds or the derivatives thereof use- 3,726,638 Patented Apr. 10, 1973 fully employed in this invention have the following formula:
- R represents a member selected from the group consisting of hydrogen and alkyl having 1 to 5 carbon atoms and r and r each independently represent a member selected from the group consisting of lower alkyl having 1 to 5 carbon atoms or together with the nitrogen atom to which they are attached form a cyclic ring, optionally containing a hetero atom; R is selected from the group consisting of alkyl having 1 to 5 carbon atoms and CH R wherein R has the same meaning given above.
- N-methylol compounds and their derivatives which correspond to the above formula include:
- N-methylol compounds may be readily prepared by known processes by the action of Formol on the respective corresponding thioamides.
- the oxidizing agent employed in the compositions of the present invention can be, for example, hydrogen peroxide or a mixture of hydrogen peroxide with a per salt such as sodium percarbonate, potassium percarbonate, sodium persulfate and potassium persulfate or a mixture of hydrogen peroxide with an organic peroxide such as urea peroxide.
- a per salt such as sodium percarbonate, potassium percarbonate, sodium persulfate and potassium persulfate
- an organic peroxide such as urea peroxide.
- the hydrogen peroxide will be employed as an aqueous solution containing about 3-9% H 0 and will be present in the composition in the aqueous form in amounts ranging from about 15-995 weight percent of the total composition.
- the per salt can be present in amounts ranging from about 5-10 Weight percent of the total composition.
- the H 0 can be present in amounts ranging from about 9-90%, while on the same basis the per salt can be present in amounts ranging from about 30-40% weight percent of said composition.
- the amount of N-methylol compound or the derivative thereof used in combination with the oxidizing agent at the time of use to form the composition of the present invention can depend on such easily ascertainable factors as the particular choice of oxidizing agent employed in the composition as well as on the specific effect that is desired.
- the amount of N-methylol compound employed is less than the stoichiometric amount relative to the oxidizing agent, but this is not mandatory, especially in the case where the composition is applied very rapidly after mixing.
- the proportion of N- methylol compound or derivative can range from 0.5 to 1.4 times the stoichiometric proportion of oxidizing agent.
- the N-methylol compound or its derivative can be present in amounts ranging from about 0.15-7 weight percent based on the total weight of the composition on an aqueous form H 0 basis. On an aqueous free H 0 basis, the amount of N-methylol compound or derivative can be present in amounts ranging from about 0.1-60 weight percent.
- novel compositions can also contain hair dyes which permit shading or coloring of the hair at the same time it is bleached. This operation is conventionally termed bleachdyeing or lightening-tinting.
- dyes that can be used in the compositions of the invention are dispersed azo dyes, either complex or soluble, or nitrated dyes such as nitroparaphenylene diamine.
- dispersed azo dyes either complex or soluble, or nitrated dyes such as nitroparaphenylene diamine.
- nitrated dyes such as nitroparaphenylene diamine.
- Representative dispersed azo dyes include the dyes sold under the trademark Cibacete (1963 Supplement, pp. 7854 6) y C ba, the tradema k. Asetoquinon p. 4103) by Francolor, the trademark Celliton (vol. 4, pp. 4181-4183) by Basf, and the trademark Artisil (vol. 4, pp. 4136-4137) by Sandoz.
- Reactant azo dyes can also be used, such as those sold under the trademark Cibacron 1963 Supplement, p. 786) by Ciba, the trademark Reactone (1963 Supplement, p. 786) by Geigy and the trademark Remazol (vol. 4, p. 4416) by Hoechst.
- Representative azo dyes with metallic complex that can be used in the compositions of the invention include dyes sold under the trademarks Cibalan (1963 Supplement, pp. 786-787) and Neolan (1963 Supplement, pp. 967- 968) by Ciba, the trademark Irgalan (1963 Supplement, p. 194) by Geigy, the trademarks Vialon-Fast (1963 Supplement, p. 1108) and Palatine-Fast (1963 Supplement, p. 992) by Bast, the trademark Inoderme (1963 Supplement, p. 912-913) by Francolor, and the trademark Lanazyn (1963 Supplement, p. 930) by Sandoz.
- N-methylol compound or derivative thereof in the oxidizing agent containing composition of this invention makes it possible to obtain a sub stantial elevation of the temperature thereof which activates the bleaching operation. Further, at this elevated temperature a release of nacent sulfur is possible which improves the appearance of the hair by substantially reducing any oily or greasy characteristics of the hair. Further, at these elevated temperatures, a polyaddition or polycondensation reaction can take place which effects a reinforcement of the keratinic fibers.
- the pH of the compositions of the present invention is selected as a function of the desired result insofar as bleaching action is concerned. In practice it is that of conventional bleaching agent, i.e. about 3.0-10.5. In this regard, it is known that in the case of weak bleaches, i.e. decolorants that are intended solely to lighten the hair slightly, the pH of these compositions at the end of the decoloration operation has an acid value. In such a situation, the methylol derivatives present in the composition give rise to polycondensation and polyaddition reactions that effect a strengthening of the keratinic fiber.
- decolorant compositions which efrect medium or strong bleaching effects, i.e. a substantial reduction of the hair coloring, have an initial and final basic pH.
- the methylol derivative present cannot cause polycondensation or polyaddition reactions.
- a rinse with an acid solution at the end of the decoloration process is employed.
- a reaction of the methylol compound or derivative then occurs which permits the attainment (35) improved hair quality and restoration of the keratinic ers.
- acid rinse media include aqueous acetic acid or formic acid solutions.
- compositions of the present invention contain proportions of oxidant compounds that correspond to those of ordinary decolorant compositions.
- the compositions of this invention can contain from 50 to 75%, preferably 50 to 66% hydrogen peroxide (6%) and from 30 to per salts.
- compositions of the invention can be provided in various commercial forms, for instance as a lotion or, preferably, a cream or gel.
- a lotion or, preferably, a cream or gel are generally employed since they are easy to use because their viscosity is high and they do not tend to run, but remain in the place where their action is required.

Filed July 9, 1970, Ser. No. 53,674 Int. Cl. D061 3/02; A61k 7/12 U.S. Cl. 8111 6 Claims ABSTRACT OF THE DISCLOSURE A composition for bleaching keratinic fibers includes a mixture of an oxidizing agent and at least one N- methylol compound which is methylated on the nitrogen of a group or a derivative thereof. The oxidizing agent is mixed with the N-methylol compound or its derivative just before application of the resulting mixture to the keratinic fibers.
This invention relates to a novel composition for the hot decoloration of human keratinic fibers.
Heretofore, the use of oxidizing compositions for decoloration of the hair have been known and such compositions employed, as the oxidizing agent, such materials as per salts, and peroxides including hydrogen peroxide. Such compositions were generally in the form of a cream or gel. These known compositions were usually applied to the fibers that were to be bleached for a suflicient period of time, generally in the order of several minutes.
It has now been found, however, that this decoloration or bleaching operation can be improved by causing an essentially spontaneous elevation of the temperature of the decoloration or bleaching composition during use, which elevation of temperature accelerates the decoloration effect produced.
Moreover, the decoloration composition of the present invention also provides strengthening of the hair which, as is known, generally becomes rather pronouncedly degraded by the action of the conventional oxidizing agents.
Moreover, as one embodiment of the present invention, the novel compositions offer the special characteristic of releasing a certain amount of nascent sulfur which improves the ultimate appearance of the hair by eliminating or substantially reducing an undesirable oily or greasy appearance or condition of the hair.
Thus, the compositions of the present invention can provide simultaneous acceleration of the bleaching action, restoration or strengthening of the hair which has undergone degradation in the oxidation reaction to decolor or bleach the same, or which has been degraded by prior treatment, and in certain instances an elimination or substantial reduction of a greasy appearance or condition of the hair.
The novel composition of this invention comprises a mixture of an oxidizing agent and at least one N-methylol compound, the methylol being on the nitrogen of a group, or a derivative of such a compound. The N- methylol compound is admixed with the oxidizing agent immediately before its use.
N-methylol compounds or the derivatives thereof, use- 3,726,638 Patented Apr. 10, 1973 fully employed in this invention have the following formula:
wherein R represents a member selected from the group consisting of hydrogen and alkyl having 1 to 5 carbon atoms and r and r each independently represent a member selected from the group consisting of lower alkyl having 1 to 5 carbon atoms or together with the nitrogen atom to which they are attached form a cyclic ring, optionally containing a hetero atom; R is selected from the group consisting of alkyl having 1 to 5 carbon atoms and CH R wherein R has the same meaning given above.
Representative N-methylol compounds and their derivatives which correspond to the above formula include:
monomethylol thiourea H 0 CHzNH-(fi-NH:
dimethylol thiourea HO CH:-NHC--NHCH2OH monomethylolethylene thiourea CHQOH Hz-Nfi dimethylolethylene thiourea CHZOH CHa-N CHz-N C H: O H
dimorpholinomethyl thiourea monomorpholinomethyl thioureaand dimorpholinomethylethylene thiourea- HzN E) These N-methylol compounds may be readily prepared by known processes by the action of Formol on the respective corresponding thioamides.
Representative derivatives of these N-methylol compounds that can be employed in accordance with the present invention are those that are obtained by etherizing the methylol function, or those obtained by a Mannich reaction, i.e. by conjugated action of Formol and a secondary amine on a thioamide.
The oxidizing agent employed in the compositions of the present invention can be, for example, hydrogen peroxide or a mixture of hydrogen peroxide with a per salt such as sodium percarbonate, potassium percarbonate, sodium persulfate and potassium persulfate or a mixture of hydrogen peroxide with an organic peroxide such as urea peroxide.
Generally the hydrogen peroxide will be employed as an aqueous solution containing about 3-9% H 0 and will be present in the composition in the aqueous form in amounts ranging from about 15-995 weight percent of the total composition. When employed, the per salt can be present in amounts ranging from about 5-10 Weight percent of the total composition. On a H O -water-free basis, the H 0 can be present in amounts ranging from about 9-90%, while on the same basis the per salt can be present in amounts ranging from about 30-40% weight percent of said composition.
The amount of N-methylol compound or the derivative thereof used in combination with the oxidizing agent at the time of use to form the composition of the present invention can depend on such easily ascertainable factors as the particular choice of oxidizing agent employed in the composition as well as on the specific effect that is desired. In general, the amount of N-methylol compound employed is less than the stoichiometric amount relative to the oxidizing agent, but this is not mandatory, especially in the case where the composition is applied very rapidly after mixing. For example, the proportion of N- methylol compound or derivative can range from 0.5 to 1.4 times the stoichiometric proportion of oxidizing agent. Expressed in other terms, the N-methylol compound or its derivative can be present in amounts ranging from about 0.15-7 weight percent based on the total weight of the composition on an aqueous form H 0 basis. On an aqueous free H 0 basis, the amount of N-methylol compound or derivative can be present in amounts ranging from about 0.1-60 weight percent.
In another embodiment of the present invention the novel compositions can also contain hair dyes which permit shading or coloring of the hair at the same time it is bleached. This operation is conventionally termed bleachdyeing or lightening-tinting.
Among the dyes that can be used in the compositions of the invention, are dispersed azo dyes, either complex or soluble, or nitrated dyes such as nitroparaphenylene diamine. With regard to the representative dyes given below, for each dye reference is made, in parenthesis, to the Color Index, 22d ed., 1956, vol. 4, or the 11963 Supplement.
Representative dispersed azo dyes include the dyes sold under the trademark Cibacete (1963 Supplement, pp. 7854 6) y C ba, the tradema k. Asetoquinon p. 4103) by Francolor, the trademark Celliton (vol. 4, pp. 4181-4183) by Basf, and the trademark Artisil (vol. 4, pp. 4136-4137) by Sandoz. Reactant azo dyes can also be used, such as those sold under the trademark Cibacron 1963 Supplement, p. 786) by Ciba, the trademark Reactone (1963 Supplement, p. 786) by Geigy and the trademark Remazol (vol. 4, p. 4416) by Hoechst.
Representative azo dyes with metallic complex that can be used in the compositions of the invention include dyes sold under the trademarks Cibalan (1963 Supplement, pp. 786-787) and Neolan (1963 Supplement, pp. 967- 968) by Ciba, the trademark Irgalan (1963 Supplement, p. 194) by Geigy, the trademarks Vialon-Fast (1963 Supplement, p. 1108) and Palatine-Fast (1963 Supplement, p. 992) by Bast, the trademark Inoderme (1963 Supplement, p. 912-913) by Francolor, and the trademark Lanazyn (1963 Supplement, p. 930) by Sandoz.
The presence of the N-methylol compound or derivative thereof in the oxidizing agent containing composition of this invention makes it possible to obtain a sub stantial elevation of the temperature thereof which activates the bleaching operation. Further, at this elevated temperature a release of nacent sulfur is possible which improves the appearance of the hair by substantially reducing any oily or greasy characteristics of the hair. Further, at these elevated temperatures, a polyaddition or polycondensation reaction can take place which effects a reinforcement of the keratinic fibers.
The pH of the compositions of the present invention is selected as a function of the desired result insofar as bleaching action is concerned. In practice it is that of conventional bleaching agent, i.e. about 3.0-10.5. In this regard, it is known that in the case of weak bleaches, i.e. decolorants that are intended solely to lighten the hair slightly, the pH of these compositions at the end of the decoloration operation has an acid value. In such a situation, the methylol derivatives present in the composition give rise to polycondensation and polyaddition reactions that effect a strengthening of the keratinic fiber.
On the other hand, it is known that decolorant compositions which efrect medium or strong bleaching effects, i.e. a substantial reduction of the hair coloring, have an initial and final basic pH. In such a situation, the methylol derivative present cannot cause polycondensation or polyaddition reactions. To obtain such a polyaddition or polycondensation reation, a rinse with an acid solution at the end of the decoloration process is employed. A lactic acid solution with a pH of 4, for example, is employed as the acid rinse medium. A reaction of the methylol compound or derivative then occurs which permits the attainment (35) improved hair quality and restoration of the keratinic ers.
Other acid rinse media include aqueous acetic acid or formic acid solutions.
The compositions of the present invention contain proportions of oxidant compounds that correspond to those of ordinary decolorant compositions. For example, the compositions of this invention can contain from 50 to 75%, preferably 50 to 66% hydrogen peroxide (6%) and from 30 to per salts.
The compositions of the invention can be provided in various commercial forms, for instance as a lotion or, preferably, a cream or gel. The latter are generally employed since they are easy to use because their viscosity is high and they do not tend to run, but remain in the place where their action is required.
The present invention also relates to a two package composition, one package containing the said methylol compound or derivative and the second package containing the oxidizing agent, the contents of said packages being mixed at the time of use to form the composition of this invention.
The present invention also relates to a process for the decoloration of keratinic fibers, especially human hair, which comprises admixing with an oxidizing agent customarily used for bleaching the hair, at least one N-methylol compound, methylated on the nitrogen of a ll s group or a derivative thereof, impregnating the keratiuic fibers with the resulting composition, permitting said composition to remain in contact with the hair for 15 to 60 minutes and thereafter washing the thus treated fibers.
As a modification of this process wherein moderate or strong bleaching of the hair is effected, alone or simultaneously with tinting or dyeing of the hair, the hair, after washing, is rinsed with an aqueous acidic rinsing medium to restore the fibers of polyaddition or polycondensation of the methylol compound.
According to the invention, a substantial increase in temperature can be attained and the degree or amount of temperature increase depends on the amount of the composition utilized, as well as on the particular methylol and oxidizing agent chosen and the amounts thereof used in the compositions of this invention. A temperature of 30 to 60 C., or even more if desired, can easily be attained with the compositions of this invention.
The following examples are given to illustrate the present invention:
EXAMPLE 1 A weak bleaching composition is prepared by adding at the time of its use 3.8 g. dimethylol thiourea to 100 g. of 10 vol.-3% H solution.
