According to the present disclosure, it is possible to provide a composition capable of reducing or suppressing fading of hair after dyeing.

It is a graph about ^{ΔE *} _ab which is involved in the anti-fading property of hair after hair dyeing by the composition of each Example and each Comparative Example.

Hereinafter, embodiments of the present disclosure will be described in detail. The present disclosure is not limited to the following embodiments, and can be variously modified and implemented within the scope of the gist of the invention.

The hair dye fading prevention composition (sometimes referred to simply as "composition") of the present disclosure includes at least one first compound selected from a specific L-ascorbic acid derivative and a salt thereof, and a cationic type first compound. Contains 2 compounds.

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

Hair is generally hydrophobic because its surface is covered with cuticles, but for example, when hair is damaged and the cuticle structure on the surface collapses, the damaged part becomes hydrophilic. It is known that it will be charged negatively.

It is believed that the fading of dyed hair is affected by the damage to the hair, which causes the dye to come off from the damaged part by shampoo or the like.

Each of the first compound and the second compound contained in the composition of the present disclosure is used as a repair agent for damaged hair and has an action of repairing damaged hair that has become hydrophilic and returning it to hydrophobicity. However, even if the first compound or the second compound is applied to dyed hair alone, fading after shampooing cannot be prevented. However, surprisingly, the present inventor has found that when the first compound and the second compound are used in combination, fading of dyed hair after shampooing can be suitably prevented. The reason why the combined system of the first compound and the second compound can suitably prevent the discoloration of dyed hair after shampooing is considered as follows.

The first compound reacts with amino groups present on the surface of undamaged hair to saturate or unsaturated the groups constituting the first compound, for example, linear or branched groups having 8 to 36 carbon atoms. Hydrophobic groups based on fatty acid residues are arranged so as to cover the surface of the hair, and can exhibit the ability to repair the surface of the hair hydrophobically. In addition, the cationic second compound is arranged so as to directly repair the damaged portion of the hair surface which is positively charged and negatively charged by the charge-attracting action.

When the dye is removed from the damaged part of the hair by shampoo or the like, it seems that the removal of the dye from the hair can be dealt with only by directly repairing the damaged part by the second compound. However, since shampoos are generally anionic, it is believed that the cationic second compound located in the repaired area will be somewhat attracted to the shampoo side from the damaged area. As a result, it is considered that a hollow portion is formed in the repair portion where the dye may come off, and sufficient anti-fading property is not exhibited.

On the other hand, in the composition of the present disclosure, first, the damaged part of the hair is repaired with the cationic second compound, and further, the amino group existing around the damaged part reacts with the first compound, and the second compound is used. It is believed that the compound repair area is covered and protected by the hydrophobic groups resulting from the reaction of the first compound with the amino group. As a result, it is considered that the cationic second compound protected by the hydrophobic group is retained without falling out from the damaged part even when shampooed, so that sufficient anti-fading property can be exhibited.

<< Composition for preventing hair dyeing and fading >>
The hair dye fading prevention composition of the present disclosure has a performance of reducing or suppressing the fading of dyed hair (this performance may be simply referred to as "fading prevention property").
