Description

Hair treatment composition containing reducing sugar {HAIR TREATMENT COMPOSITION CONTAINING REDUCING SUGAR}

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

Generally, a product for changing the shape of the hair includes a composition for perma, which is divided into a first agent and a second agent. According to the procedure, it is called permanent wave agent and straight permanent agent. In general, the first agent reducing agent is thioglycolic acid or salts thereof, cysteine or salts thereof, which are reduced by reducing cysteine bonds in the hair, and hydrogen peroxide. Oxidative recombination is carried out by treating binary neutralizers using water or sodium bromide as main components to form waves and straight lines. The wave and straight styles thus formed have excellent lasting effects, such as lasting more than 3 months, but have a bad smell due to the main ingredient used during the procedure, and the aftertaste remains after the procedure. The disadvantage is that chemical reactions cause severe chemical damage to the hair. In addition, there is a hassle to use the first and second agents sequentially.

In recent years, keratin treatments have been in the spotlight for the treatment of hair curling without giving chemical damage to the hair but rather giving a conditioning effect like a clinic. Initially in Latin America, Brazilian Keratin Treatment products and procedures began. After that, Keratin Treatment products were released under various product names. Early keratin treatments showed the effect / effect by inducing crosslinking to the hair using formaldehyde, a harmful substance, but since the used formaldehyde became an issue, recently released products are free of formaldehyde (free). We are launching the product. However, these formaldehyde free keratin treatment products simply use high amounts of keratin protein to give only the hair conditioning effect due to the outer coating of the hair, but the straightening effect is poor.

Republic of Korea Patent Publication No. 2008-0072750

In order to solve the problems described above, the present invention provides a hair treatment composition containing reducing sugars having excellent hair conditioning effect and excellent straight / wave style sustainability without using formaldehyde, which is an eye to keratin treatment products. Its purpose is to provide.

In order to solve the above object, the present invention provides a hair treatment composition containing a 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 (Glucose), fructose (Fructose), galactose (Galactose), lactose (Lactose) and Maltose (Maltose) It may be more than one species.

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

In one embodiment of the invention, the composition may further contain one or more of amino acids or proteins.

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

In one embodiment of the invention, the composition may be in contact with the hair at 60 to 200 ℃ to cause a Maillard reaction (Maillard).

In addition, the present invention is to apply the hair treatment composition to the 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 to use a hot air balloon comprising a dryer and iron.

According to the hair treatment composition of the present invention, it is not only excellent in the effect of conditioning the damaged and powerless hair without using formaldehyde, which is a harmful substance, and makes the curly busy hair in a straight / wave style and its style The persistence that keeps this is excellent.

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 a reducing sugar as an active ingredient.

In the present invention, the reducing sugar refers to a saccharide capable of reducing other chemical components under certain reaction conditions. An aldehyde group (-CHO, reduced terminus) in the chemical structure of the saccharide or an aldehyde group generated while isomerizing in a solution is a carboxyl group (-COOH). It can be seen through Benedict test and Tolene test to reduce other oxides while oxidizing.

In the present invention, the reducing sugar may be any type of reducing sugar conventionally used in food and cosmetics, and may be variously selected and used according to the feeling, price, efficacy, and effect on hair. Preferably, it may be one or more selected from the group consisting of xylose, glucose, glucose, fructose, galactose, lactose, maltose and maltose. Xylose, glucose, fructose and galactose are monosaccharides, and lactose and maltose are disaccharides having an aldehyde group at their ends. However, sucrose, trehalose, and the like are non-reducing sugars that do not have a reducing sugar structure and thus cannot be used in the present invention.

In the present invention, the reducing sugar may be contained from 0.01 to 10% by weight based on the total weight of the composition. More preferably, it may be 1 to 3% by weight. If the content of reducing sugar is less than 1% by weight, the effect may be weakened. If the content of reducing sugar is more than 3% by weight, the stickiness and weight are severe and may cause discomfort when using the product.

The composition may further contain one or more of amino acids or proteins. Protein / amino acid having an amine group that can be used in addition to the present invention can be used for animal proteins such as keratin, silk and vegetable proteins derived from wheat, soybean, walnut, etc. generally used in cosmetics, arginine having an amine group ( Amino acids such as Arginine, Lysine, Histidine, etc. may be used, but are not limited thereto. When the composition includes an amino acid or a protein component having an amine group, the polymer compound produced by the reaction outside the hair coats the hair to provide an elastic and soft feeling.

In one embodiment of the present invention, the composition may be of a first formulation leave-on type that does not wash off after application to the hair. The reducing sugar used as an active ingredient in the composition of the present invention and the protein / amino acid having an amine group which may be further contained are both water-soluble, and can be composed of the first formulation because the reaction does not occur at room temperature, all in cosmetics or food It is characterized by the fact that the formulation can be formulated as a leave-on type which is used and has been tested for safety. The first type of rib-on type products that do not need to be washed are easy to use and have the advantage of being often applied.

The composition may contact the hair at 60 to 200 ° C. to cause a Maillard reaction. Reducing sugars having an aldehyde group react with a protein / amino acid having an amine group (-NH ₂ ) at a high temperature to form a new polymer compound called melanoidin through an intermediate product. This reaction is called the Maillard reaction. The present inventors solved the problem by applying the Maillard reaction to the hair. Reducing sugar and hair does not occur under normal room temperature conditions, but it was confirmed that the reaction occurs when heated to 60 to 200 ℃ 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. Due to this, the reducing sugar enters and binds the damaged hair to fill the empty hair and maintain the style made of the structural bulkiness.

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

Treatment compositions according to the invention can be formulated into hair treatments, essences, serums, ampoules, creams, mists, and the like, and can be prepared by conventional methods.

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 to use a hot air balloon including a dryer and iron, but is not limited thereto. As described above, when the composition of the present invention is brought into contact with hair and heat is applied, a Maillard reaction may occur to create a straight or wave style hairstyle as desired by the user. You do not have to wash the composition after the hair is warmed up.

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 sustainability is possible.

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