Detailed Description

Hereinafter, embodiments of the present disclosure will be described in detail. The present disclosure is not limited to the following embodiments, and various modifications can be made within the spirit of the invention.

The composition for preventing fading of hair color (sometimes simply referred to as "composition") according to the present disclosure contains at least one 1 st compound selected from specific L-ascorbic acid derivatives and salts thereof, and a 2 nd compound of a cationic system.

Although not limited by the principle, the action principle of such a composition to reduce or suppress the fading of hair after dyeing is considered as follows.

Hair is generally known to exhibit hydrophobicity because its surface is covered with epidermis (cuticle), but for example, if hair is damaged and the epidermal structure of the surface collapses, the damaged portion exhibits hydrophilicity and is negatively charged.

Furthermore, it is considered that the discoloration of the dyed hair is affected by the following: the hair is damaged, and the dye is removed from the damaged portion by shampooing or the like.

It is known that the 1 st compound and the 2 nd compound contained in the composition of the present disclosure are each used as a healant for damaged hair or the like and have an effect of repairing damaged hair that has become hydrophilic and restoring hydrophobicity, but even if the 1 st compound or the 2 nd compound is applied alone to dyed hair, the fading after shampooing cannot be prevented. However, surprisingly, the present inventors have found that when the 1 st compound and the 2 nd compound are used in combination, the hair dyed with the compound can be suitably prevented from fading after shampooing. The reason why the combined system of the compound 1 and the compound 2 can suitably prevent the discoloration of dyed hair after shampooing is considered as follows.

The compound 1 can react with an amino group present on the surface of an undamaged hair, and is disposed so that the surface of the hair is covered with a hydrophobic group based on a group constituting the compound 1, for example, a linear or branched saturated or unsaturated fatty acid residue having 8 to 36 carbon atoms, and exhibits a property of repairing the surface of the hair to be hydrophobic. The cationic 2 nd compound is positively charged and is disposed so as to directly repair a damaged portion on the surface of negatively charged hair by the attraction effect of the charge.

In the case where the dye is dropped from the damaged portion of the hair by shampooing or the like, the dropping of the dye from the hair seems to be treatable only by direct repair of the damaged portion with the 2 nd compound. However, since the shampoo generally has anionic properties, it is considered that the cationic compound 2 disposed in the repaired portion is slightly pulled from the damaged portion toward the shampoo side. As a result, it is considered that a void portion such as a dye drop is generated in the repaired portion, and sufficient discoloration prevention property is not exhibited.

On the other hand, it is considered that the composition of the present disclosure firstly repairs a damaged part of hair with the cationic compound 2, and further, amino groups present around the damaged part react with the compound 1, and a repaired part obtained from the compound 2 is covered and protected with a hydrophobic group by the reaction of the compound 1 with the amino group. As a result, it is considered that the cationic compound 2 protected by the hydrophobic group is not peeled off from the damaged portion and is retained even after shampooing, and thus sufficient discoloration prevention property can be exhibited.

Composition for preventing fading of hair dye

The composition for preventing fading of hair color of the present disclosure has a property of reducing or suppressing fading of hair colored (this property is sometimes referred to simply as "fading-preventing property"). The fading prevention property can be determined by measuring the color of hair dyed with a hair dye before and after shampooing with a spectrophotometer under the conditions of a fading prevention test described later, and determining the difference in color (Δ Ε) between the measured color and the measured color _ab ) To evaluate.

Further, a buffer solution (for example, sodium salt of phosphoric acid-phosphoric acid) or the like using a combination with these salts may be used. Preferred examples of the alkaline agent include ammonia, ammonium salts, and alkanolamines. These alkaline agents may be used alone or in combination of two or more.

(oxidizing agent)

In several embodiments, the hair color fading prevention composition of the present disclosure may comprise an oxidizing agent. The oxidizing agent has an action of promoting the decolorization of melanin pigment in hair, and also has an effect of determining coloring effect by oxidatively polymerizing an oxidation dye intermediate and an optional coupler.

The pasty composition is more easily held on hair than the liquid composition, and the 1 st compound and the 2 nd compound in the composition of the present disclosure are more easily fixed to the surface or damaged portion of hair, and therefore, the fading prevention property can be further improved.

The viscosity (viscosity at the time of application) of the mixed state of the 1 st agent and the 2 nd agent used in the 2-agent type hair dye set as the cream composition may be, for example, 10,000mPa · s or more, 20,000mPa · s or more, 30,000mPa · s or more, 40,000mPa · s or more, 45,000mPa · s or more, or 50,000mPa · s or more, from the viewpoint of ease of application to hair, for example. The upper limit of the viscosity of the paste composition is not particularly limited, and may be, for example, 100,000mPa · s or less, 80,000mPa · s or less, 60,000mPa · s or less, 55,000mPa · s or less, or 50,000mPa · s or less, from the viewpoint of ease of spreading to hair. Here, the viscosity is measured at 2rpm in an atmosphere of 25 ℃ using a B-type viscometer (RVDVI + model RV, manufactured by ブルックフィールド Co., Ltd., rotor No. 6).

The composition of the present disclosure may be in the form of an oil-in-water or water-in-oil emulsion prepared using water, a surfactant, oil, or the like.
