Description

[0001] HAIR TREATMENT COMPOSITION CONTAINING REDUCING SUGAR [0002]

The present invention relates to a hair treatment composition containing reducing sugar as an active ingredient.

In general, there are compositions for changing the shape of the hair, such as a composition for a permer that is divided into a reducing agent 1 and a neutralizing agent 2. Depending on the method to be used, it is called permanent waving agent and straight perming agent. In general, thioglycolic acid or its salt, cysteine or its salt is used as a main ingredient in the reducing agent 1, and these are cut off by reducing the cysteine bond in the hair, A second neutralizing agent using water or sodium bromate as a main component is treated and oxidized and recombined to form a wave and a straight. The wave and straight style formed in this way exhibits excellent durability such as lasting for 3 months or more, but there is a problem that the odor caused by the main ingredient used in the treatment is significant and the remnant remains after the treatment. The disadvantage is that chemical reactions cause serious chemical damage to the hair. Also, it is troublesome to use 1 and 2 sequentially.

In recent years, keratin treatment, which does not cause chemical damage to the hair but rather curls the hair with a conditioning effect like a clinic, is getting popular. Brazilian Keratin Treatment products and treatments started in the early South American continent. Since then, Keratin Treatment products have been launched under various product names. Early keratin treatments used formaldehyde, a harmful substance, to induce crosslinking in hair and showed its efficacy / efficacy. However, recently, formaldehyde has become an issue, ), And is launching products. However, these formaldehyde-free keratin treatment products merely use a high amount of keratin protein to give hair conditioning effect due to the outer coating of hair, but the hair straightening effect is poor.

Korea Patent Publication No. 2008-0072750

In order to solve the above-mentioned problems, the present invention provides a hair treatment composition containing reducing sugar having excellent hair conditioning effect and at the same time having excellent straight / wave style sustainability without using formaldehyde as a harmful substance, The purpose is to provide.

In order to solve the above-mentioned problems, the present invention provides a hair treatment composition containing reducing sugar as an active ingredient.

In one embodiment of the present invention, the reducing sugar is selected from the group consisting of Xylose, Glucose, Fructose, Galactose, Lactose and Maltose. It can be more than a species.

In one embodiment of the present invention, the reducing sugar may be 0.01 to 10% by weight based on the total weight of the composition.

In one embodiment of the present invention, the composition may further contain at least one amino acid or protein.

In one embodiment of the present invention, the composition may be a leave-on type first formulation that is not washed after application to the hair.

In one embodiment of the present invention, the composition may be one which contacts the hair at 60 to 200 ° C to cause a Maillard reaction.

The present invention also relates to a method of treating hair comprising applying the hair treatment composition to hair; And heating the hair to which the composition is applied to 60 to 200 캜.

In one embodiment of the present invention, the heating may be performed using a hot air balloon including a dryer and an iron.

According to the hair treatment composition of the present invention, not only harmful substances such as formaldehyde are used but they are excellent in conditioning damage to damaged hair, and also make curly, coarse hair straight / wave style, Is maintained.

Hereinafter, preferred embodiments of the present invention will be described in detail in order to facilitate the present invention by those skilled in the art.

The present invention provides a hair treatment composition containing reducing sugar as an active ingredient.

In the present invention, the reducing sugar refers to a saccharide capable of reducing other chemical components under a certain reaction condition. The aldehyde group (-CHO, reducing end) in the sugar structure or the aldehyde group generated by isomerization in the solution is a carboxyl group (-COOH) And the other oxides are reduced by the Benedictine test and the Tollen test.

In the present invention, reducing sugar is conventionally used regardless of the kind of reducing sugar used in foods and cosmetics, and can be selected and used variously according to the feel, price, efficacy, and effect in the hair. Preferably, it may be at least one selected from the group consisting of Xylose, Glucose, Fructose, Galactose, Lactose and Maltose. Among them, Xylose, Glucose, Fructose, Galactose are monosaccharides, and Lactose and Maltose are disaccharides having an aldehyde group at the terminal. However, sucrose, trehalose and the like can not be used in the present invention because they are non-reducing sugars having no reducing sugar structure.

In the present invention, the reducing sugar may be 0.01 to 10% by weight based on the total weight of the composition. More preferably 1 to 3% by weight. If the content of the reducing sugar is less than 1% by weight, the effect thereof may be weakened. If the content of the reducing sugar is more than 3% by weight, stickiness and weight may be excessive.

The composition may further contain at least one of an amino acid or a protein. Protein / amino acid having an amine group that can be used in the present invention may be an animal protein such as keratin or silk generally used in cosmetics, vegetable protein derived from wheat, soybean, walnut, etc., and arginine Amino acids such as arginine, lysine, histidine and the like may be used, but the present invention is not limited thereto. When an amino acid or a protein component having an additional amine group is contained in the composition, the polymer compound produced due to the reaction outside the hair coats the hair to provide a resilient and soft feeling.

In one embodiment of the present invention, the composition may be of a first-form, leave-on type that is not washed after application to the hair. Since both the reducing sugar used as an active ingredient in the composition of the present invention and the protein / amino acid having an amine group that can be additionally contained are both water-soluble and the reaction does not occur at room temperature, they can be composed of the first formulation, It is characterized by being able to constitute the formulation as a leave-on type which is not washed out as used with proven safety ingredients. First formulations that do not need to be rinsed Rib-on type products are easy to use and have the advantage of being worn over time.

The composition may contact the hair at 60 to < RTI ID = 0.0 > 200 C < / RTI > to cause a Maillard reaction. Reducing sugars with an aldehyde group react with a protein / amino acid having an amine group (-NH ₂ ) at a high temperature to produce an intermediate product and ultimately a new polymer compound called melanoidin. This reaction is called the Maillard reaction. Therefore, the present inventors have solved the problem by applying the above-mentioned mailard reaction to hair. Although the reaction does not occur at the normal temperature condition of the reducing sugar and the hair, it is confirmed that the reaction occurs when heated to 60 to 200 DEG C by using a hot air balloon such as iron or dry. When the hair is treated with a treatment composition containing reducing sugar and heat is applied to the hair using a hot air balloon such as iron / dry, the hair reacts with the amine group present in the keratin protein to form a chemical bond. As a result, the reducing sugar inside the hair is damaged by the binding, filling the empty hair and maintaining the style made of structural bulkiness for a long time.

The hair treatment composition according to the present invention may contain water or ethanol as a solvent and may contain at least one other additive selected from the group consisting of oils, thickeners, surfactants, conditioning agents, moisturizers, fragrances, . The above-mentioned ingredients are easily selected and used by those skilled in the art as materials included in conventional hair treatments.

The treatment composition according to the present invention can be formulated into hair treatments, essences, serums, ampoules, creams, mists and the like, and can be prepared by a conventional method.

The present invention also relates to a method of applying the hair treatment composition of the present invention described above to hair; And heating the hair to which the composition is applied to 60 to 200 캜. If the hair to which the composition is applied is less than 60 ° C, the mailard reaction does not occur and the effect is not manifested. If the hair is heated to more than 200 ° C, severe heat damage to the hair may occur.

The heating may be performed using a hot air balloon including a dryer and an iron, but is not limited thereto. As described above, when the composition of the present invention is brought into contact with the hair and the hair is heated, a Maillard reaction occurs so that a hair style such as a straight or wave style can be produced as desired by the user. The composition may not be washed after heating the hair.

According to the hair treatment composition of the present invention, a hair treatment having an excellent hair conditioning effect and an excellent straight / wave style duration is possible.

The present invention will be described in more detail through the following examples. However, the examples are for illustrating the present invention, and the scope of the present invention is not limited thereto.
