DESCRIPTION

USE OF TRIAZINE DERIVATIVES FOR PERMANENT DEFORMATION OF

KERATIN FIBERS TECHNICAL FIELD

The present invention relates to a cosmetic composition for keratin fibers such as hair.

BACKGROUND ART

Many hair care products are marketed nowadays to easily style, texturize and add weight to hair, especially to tWnning hair, among which foams and styling gels or hair lacquers may be mentioned as examples. These products enable shaping of the hair but are removed with shampoo and thus are required to be applied on a daily basis.

The most general technique for obtaining a long-lasting deformation of hair consists, in a first step, of opening the keratin S-S disulfide bonds (cystine) with a composition comprising a suitable reducing agent (reducing step) then, once the thus treated hair has been rinsed, generally with water, reforming said disulfide bonds in a second step, by applying an oxidizing composition onto the hair which has been placed beforehand under tension, using curlers for example (oxidizing step, also called fixing step) so as to give the hair the desired form in the end.

The new shape that is imposed to the hair by means of a chemical treatment, such as explained above, is relatively long-lasting and is relatively resistant to washing operations with water or shampoo, as compared to the usual simple methods for temporarily reshaping the hair by using foams, styling gels, or lacquers.

Many compositions and processes for the above chemical treatment have been proposed.

Generally, they offer good performance on the day of treatment.

DISCLOSURE OF INVENTION

To achieve good hair shape modification performance, the composition for opening the cystine bonds contains a relatively high concentration of one or more reducing agents under the high alkaline condition. For example, thioglycolic acid, which is one of the common reducing agents, is in general used in an amount between 6 and 11 wt%, with a pH range of from 8.5 to 9.5.

Additionally, some hair deformation technologies use heating process during the reducing step in order to increase the chemical action of such reducing agents. Therefore, the hair undergoes substantial degradation that does not permit consumers to consider repeated applications nor treatment combinations (for example, perm and coloration).

In addition, thiol-based compounds which are commonly used as reducing agents for conventional hair deformation processes have malodor, and therefore, the malodor is not preferable either for consumers. An objective of the present invention is to provide a cosmetic composition for keratin fibers which can prevent or reduce the degradation of the keratin fibers by the deformation process based on conventional deformation processes for the keratin fibers, without any malodor. The above objective can be achieved by a cosmetic composition for keratin fibers comprising at least one compound represented by the following general formula (I) or a salt thereof:

wherein

each of Ri and R ₂ independently represents a hydrogen atom, a CMO alkyl group, a C _2-10 alkenyl group, a Ce-io aryl group, or a C ₇ . ₁₀ aralkyl group; these groups optionally being substituted by at least one group chosen from a hydroxyl group, an amino group, a carboxy group, and a C _2-10 acyl group; and

X represents a halogen atom, a trifluoromethanesulfonyloxy group, a piperidinyl group, a piperazinyl, an morpholinyl group, an N-alkylmo holinium group, or where R ₃ , T and R ₅ independently represent a C _1-10 alkyl group, a C ₂ . ₁₀ alkenyl group, a C _6-1 o aryl group, a C _7-10 aralkyl group, -CH ₂ -COO-C _m H _2m+ i (m denotes an integer from 1 to 10), or

(n denotes an integer of from 1 to 10). When, in the above formula (I), X represents an N-alkylmorpholinium group, it is preferably an N-memylmorpholinium group.

In the above formula (I), both Ri and R ₂ may represent a hydrogen atom. In the above formula (I), at least one or two of R ₃ , R4 and R5 may represent a C _1-10 alkyl group, preferably a methyl group.

The salt may be a salt with organic or inorganic acid or a salt with organic or inorganic base.

Particularly , if X represents an N-alkylmorpholinium group or the compound (I) may be a salt with an anion selected from the group consisting of halide ions, triflates, nitrates, sulfates, sulfonates, boron fluorides, and perchloates.

composition.

The pH of the cosmetic composition-according to the present invention may be from 2 to 11 , and preferably from 3 to 10, and more preferably from 4 to 9.

The cosmetic composition according to the present invention may further comprise at least one pH adjusting agent.

The cosmetic composition according to the present invention may further comprise at least one cationic polymer. The cosmetic composition according to the present invention may further comprise a thiol-based compound, preferably at low concentration, such as up to 0.1% by weight relative to the total weight of the composition.

Another objective of the present invention is to provide a process for permanent deformation of keratin fibers which can prevent or reduce the degradation of the keratin fibers by the permanent deformation process for the keratin fibers, without any malodor.

The above objective can be achieved by a process for permanent deformation of keratin fibers comprising the steps of:

applying onto the keratin fibers the cosmetic composition according to the present invention; and keeping the keratin fibers under from a room temperature to an elevated temperature.

The process according to the present invention may further comprise the step of providing the keratin fibers with mechanical tension for the deformation before and/or after the step of applying onto the keratin fibers the cosmetic composition according to the present invention.

The process according to the present invention may further comprise the step of rinsing the keratin fibers after the step of applying onto the keratin fibers the cosmetic composition according to the present invention and/or after the step of keeping the keratin fibers from room temperature to an elevated temperature.

The elevated temperature may be from 50 to 250°C, preferably 80 to 200°C and more preferably 100 to 180°C. In the process according to the present invention, the keratin fibers may be heated to the elevated temperature by at least one heater selected from the group consisting of hot air, hot steam, high frequency induction heating, microwave heating, infra-red ray irradiation, ultrasonic wave, laser, and flash lamp irradiation. The process according to the present invention may not comprise a step of oxidizing the keratin fibers.

and

X represents a halogen atom, a trifluoromethanesulfonyloxy group, a piperidinyl group, a piperazinyl, an morpholinyl group, an N-alkylmorpholinium group, or -N^RiRs where R ₃ , R4 and R ₅ independently represent a C _1-10 alkyl group, a C _2-10 alkenyl group, a C ₆ . ₁₀ aryl group, a

C _7-1 o aralkyl group, -CH2-COO-C _m H _2m+1 (m denotes an integer from 1 to 10), or -C ₆ H ₄ -p-C _n H _2n+1 (n denotes an integer of from 1 to 10), for permanent deformation of keratin fibers.

BEST MODE FOR CARRYING OUT THE INVENTION

General permanent hair shape modification process gives a lot of damage to hair fibers due to insufficient recombination of disulfide-bonding linkage, as well as the hydrolysis of keratin protein and their extraction from hair under the high alkaline condition. Especially, repeated applications or in combination with other chemical treatments such as oxidative coloration give high levels of hair damage. Such hair damage leads to the insufficient long-lastingness of the hair shape modification effect against environmental stress such as mechanical constraints from daily shampoo, bmshing, humidity, UV and the like.

After diligent research, the inventors have discovered that it is possible to perform a new permanent deformation of keratin fibers such as hair, eyelash, eyebrow and the like, which reduces the damages to the keratin fibers and malodor by using thiol-based compounds.

The inventors have found that some specific triazine-based compounds can give good hair shape modification effect even at room temperature process without hair damage. The above triazine-based compounds form an amide bond (-CONR-) by the direct condensation of a carboxylic acid moiety and an amine moiety in the protein in the keratin fibers, in stead of forming -S-S- disulfide bond to deform or reshape the keratin fibers.

Thus, the cosmetic composition and the deformation process for the keratin fibers such as hair according to the present invention can prevent or reduce the degradation of the keratin fibers by the deformation process for the keratin fibers, because the present invention is based on a new principle of the permanent deformation of keratin fibers, and is no longer based on the

conventional permanent deformation based on the reduction-oxidation of disulfide bonds in the keratin fibers.

The cosmetic composition according to the present invention does not need to contain any reducing agent such as a thiol-based compound. Therefore, no oxidative step is required to achieve the hair shape modification effects. This means that no malodor derived from the reducing agent is present or generated; no additional hair degradation by the high alkaline condition for the reducing agent or by the oxidative step is caused; and one step process can be achieved by the sole use of the cosmetic composition according to the present invention.

Hereafter, each of the cosmetic composition for keratin fibers and the process for permanent deformation of keratin fibers according to the present invention will be described in a detailed manner.

(Thiol-based compound)

The cosmetic composition according to the present invention does not need to contain any reducing agent such as a thiol-based compound. Therefore, malodor derived from the reducing agent can be prevented. Furthermore, degradation of the keratin fibers can be prevented, because no strong alkali is necessary.

The cosmetic composition according to the present invention may contain thiol-based compound. It is preferable, however, that the cosmetic composition according to the present invention comprise no thiol-based compound with malodor.

The "thiol-based compound" means a compound with at least one thiol. The thiol-based compound may be chosen from the group consisting of thioglycolic acid and derivatives thereof, in particular esters thereof such as glycerol or glycol monothioglycolate; dithioglycolic acid and derivatives thereof in particular esters thereof such as glycerol or glycol dithioglycolate; thiolactic acid and derivatives thereof, in particular esters thereof such as glycerol monothiolactate;

As the primary-, secondary- or tertiary-amine, for example, monoemanolamine, di-isopropanolamine or triemanolamine, respectively, may be mentioned.

However, the cosmetic composition according to the present invention may contain a small amount of at least one thiol-based compound, as long as the thiol-based compound does not hinder or reduce the effect of the present invention. For example, the cosmetic composition may contain 0.1% by weight or less, preferably 0.01% by weight or less, and more preferably 0.001% by weight or less, of a thiol-based compound, relative to the total weight of the cosmetic composition.

(Additives)

The cosmetic composition according to the present invention may also comprise one or more additives. The amount of the additive(s) is not limited, but may be from 0.1 to 10% by weight relative to the total weight of the cosmetic composition. The additive(s) may be selected from the group consisting of volatile or non volatile, linear or cyclic, silicones other than aminosilicones, anionic, nonionic or amphoteric polymers, peptides and derivatives thereof, protein hydrolyzates, synthetic or natural waxes, swelling agents and penetrating agents, as well as other active compounds, such as anionic, cationic, amphoteric or zwitterionic surfactants, non ionic surfactants other than oxyalkylenated fatty alcohols, agents for combating hair loss, anti-dandruff agents, associative-type or not, natural or synthetic thickeners, suspending agents, sequestering agents, opacifying agents, dyes, sunscreen agents, fillers, vitamins or provitamins, mineral, vegetable or synthetic oils, as well as fragrances, preserving agents, stabilizers, and mixtures thereof.

The water may be present in a concentration of from 10 to 90% by weight relative to the total weight of the cosmetic composition. The organic solvent(s) may then be present in a concentration of from 0.1 to 20% by weight, and preferably from 1 to 10% by weight relative to the total weight of the composition.

The cosmetic composition according to the present invention may exist in any form such as a lotion, a gel, thickened or not, a foam, or a cream. (Permanent Deformation Process)

The process for permanent deformation of keratin fibers according to the present invention comprises, at least, the steps of:

applying onto the keratin fibers the cosmetic composition according to the present invention as explained above; and keeping the keratin fibers under room temperature or higher (i.e., an elevated temperature).

According to the process for permanent deformation of keratin fibers, such as hair, of the present invention, the keratin fibers may be subjected to mechanical tension which is typically used for permanent deformation.

The permanent deformation process for keratin fibers according to the present invention when mechanical tension is applied to keratin fibers may be performed as follows. First, keratin fibers are subjected to mechanical tension for deformation. The mechanical tension can be applied to the keratin fibers by any means to deform the keratin fibers to an intended shape. For example, the mechanical tension may be provided by at least one reshaping or mechanically tensioning means selected from the group consisting of a curler, a roller, a clip, a plate and an iron. If the keratin fibers are rolled around a curler, this rolling-up may be performed on the entire length of the keratin fibers or, for example, on half the length of the keratin fibers. Depending on, for example, the desired hairstyle shape and amount of curls, the rolling-up may be performed with more or less thick locks.

Next, the cosmetic composition according to the present invention is applied to the keratin fibers. The application of the cosmetic composition according to the present invention may be performed by any means, such as a brush and a comb. It is preferable that the keratin fibers, to which the mechanical tension has been applied, be treated with the cosmetic composition according to the present invention. Lastly, the keratin fibers are maintained at room temperature or higher. If the keratin fibers are maintained at an elevated temperature, the keratin fibers are heated by applying heat energy to the keratin fibers.

Room temperature here means from 20 to 30 °C, and is typically 25 °C. The elevated

temperature is not limited as long as it is higher than room temperature. In one embodiment, the elevated temperature can be from 50 to 250°C, preferably 80 to 200°C and more preferably 100 to 180°C.

The time for heating the keratin fibers to be maintained at an elevated temperature is not limited, but preferably be from 1 second to 2 hours, and more preferably 1 minute to 1 hour.

The means to heat the keratin fibers to maintain them at an elevated temperature is not limited. One or more heating means may be used. The heating means or heater may be selected from the group consisting of hot air, hot steam, high frequency induction heating, microwave heating, infra-red ray irradiation, ultrasonic wave, laser, and flash lamp irradiation.

The reshaping or mechanically tensioning means may comprise at least one heater.-

If necessary, the cosmetic composition according to the present invention may be applied to the keratin fibers before applying mechanical tension to the keratin fibers. It is possible that the keratin fibers be left as they are for a certain amount of time, if necessary, before and/or after applying mechanical tension to the keratin fibers, before and/or after applying the cosmetic composition according to the present invention to the keratin fibers, and before and/or after mamtaining the keratin fibers under from a room temperature to a higher temperature (an elevated temperature).

The permanent deformation process for keratin fibers according to the present invention may further comprise the step of rinsing the keratin fibers after the step of applying onto the keratin fibers the cosmetic composition according to the present invention and/or after the step of keeping the keratin fibers under from at room temperature to an elevated temperature.

According to the process for deforming the keratin fibers according to the present invention, at least one amide bond is formed by the direct condensation of carboxylic acid moieties and amine moieties of the proteins in the keratin fibers. Here, the term "direct condensation" means that the compound according to the above formula (Γ) is not present in the final product with formed amide bond. Thus, the compound according to the above formula (I) acts as a catalyst.

Moreover, the shape of the keratin fibers can be deformed by the formation of the amide bond, not disulfide bond based on conventional permanent deformation technologies based on reduction and oxidation.

The process according to the present invention does not have to include a step of oxidizing the keratin fibers, because it does not reduce the disulfide bonds in the keratin fibers. Preferably, the process according to the present invention comprises no step of oxidizing the keratin fibers.

Therefore, the process according to the present invention can also prevent or reduce the degradation of the keratin fibers due to the oxidation process, typically the oxidation by an oxidizer such as hydrogen peroxide. Furthermore, the time required for the process according to the present invention can be shorter than that for a conventional process which needs an oxidizing step.

The whole time required for the process according to the present invention may be a few minutes to 2 hours, preferably 5 minutes to 1 hour, and more preferably 10 to 30 rninutes. One embodiment of the process for permanent deformation of keratin fibers such as hair according to the present invention may be a process for reshaping or permanently deforming keratin fibers, in particular hair, comprising:

a) a step of placing the keratin fibers under mechanical tension by rolling them up on at least one reshaping or mechanically tensioning means so as to form curls of the keratin fibers; b) a step of applying the cosmetic composition according to the present invention to the

keratin fibers;

c) an optional step of rinsing the keratin fibers,

d) ^" a step of heating the keratin fibers at a temperature of from a room temperature to an

elevated temperature such as a temperature between 50 and 250°C, and

e) an optional step of rinsing the keratin fibers. Another embodiment of the process for permanent deformation of keratin fibers such as hair according to the present invention may be a process for reshaping or permanently deforming keratin fibers, in particular hair, comprising:

a) a step of applying the cosmetic composition according to the present invention to the

keratin fibers;

b) an optional step of rinsing the keratin fibers,

c) a step of placing the keratin fibers under mechanical tension by rolling them up on at least one reshaping or mechanically tensioning means so as to form curls of the keratin fibers, or by pressing them by at least one reshaping or mechanically tensioning means to as to straighten the keratin fibers, followed by or while heating the keratin fibers at a temperature of from a room temperature to an elevated temperature such as a temperature between 50 and 250°C, and

d) an optional step of rinsing the keratin fibers.

According to the present invention, it is preferable that the temperature of the keratin fibers be kept constant with a fluctuation of ± 2 or 3°C over the head, if the keratin fibers are hair, of an individual. Thus, the hair style becomes uniform and homogeneous over the entirety of the hair, and a more excellent hair style can be obtained.
