Description

Hair dye composition

Technical Field

The present disclosure relates to hair dye compositions, and in particular to hair dye compositions containing direct dyes.

Background

Hair dye compositions containing direct dyes are generally used as semi-permanent hair dyes for various coloring agents. On the other hand, the following oxidative hair dyes are also known: the oxidation fuel penetrates into the hair cuticle by the action of the alkaline agent, and the decomposition of melanin and the color development of the dye are performed by the oxidizing agent. The semi-permanent hair dye has an advantage of being able to suppress damage to hair compared to an oxidative hair dye, while the semi-permanent hair dye is weaker in hair dyeing ability than the oxidative hair dye. Further, the semi-permanent hair dye is likely to adhere to the periphery of the user, clothing, skin, and the like from the time of dyeing to the time of leaving (hereinafter, the degree to which the hair dye applied to the hair is likely to adhere to the periphery of the user, clothing, skin, and the like is referred to as "migration property"). Therefore, when using a semi-permanent hair dye, it is necessary to prepare and carefully handle the hair dye in advance so as not to cause the hair dye to adhere to a part other than the hair, and this tends to cause a burden on the user.

The following dye composition was proposed in view of the above problems. Patent document 1 describes that a hair dye composition containing a specific polysaccharide and a specific polymer compound does not drip when applied to hair. Patent document 2 describes that the hair dyeing auxiliary contains a specific alcohol to reduce the dyeing property on the skin during dyeing and to exhibit a good dyeing property on hair.

ADVANTAGEOUS EFFECTS OF INVENTION

According to one aspect of the present disclosure, a hair dye composition having reduced migration properties and improved hair dyeing properties can be provided.

Detailed Description

According to the inventors' studies, quick-drying and film-forming properties can be imparted to hair dye compositions by the above components. Therefore, according to the hair dye composition, the hair dye applied to the hair can be prevented from adhering to the periphery of the user, clothes, skin, and the like, and the contamination occurring from the hair dye application process to the hair dye leaving period can be reduced. Further, the hair dye composition can reduce the migration property while suppressing the influence on the hair dyeing property. That is, the above components can provide a hair dye composition having reduced migration property and high dyeing property.

The respective components contained in the hair dye composition will be described in detail below.

(A) The component (A) imparts a film-forming property to the hair dye composition, thereby reducing the migration property. Further, since the component (a) is a component which has little influence on the hair dyeing property, a hair dye composition having a reduced migration property and a high hair dyeing property can be obtained by blending the component (a). Furthermore, since the hair dye composition is left to stand for a predetermined time after being applied to hair and then subjected to rinsing treatment, the film formed by the component (a) is not a so-called hydrophobic film but a film which is easily rinsed with water, and therefore, the hair dye can be easily rinsed.

The component (a) is not particularly limited as long as it is a polymer compound having at least one skeleton selected from a pyrrolidone skeleton and a caprolactam skeleton, and preferably a polymer having a unit derived from at least one vinyl compound selected from N-vinylpyrrolidone and N-vinylcaprolactam is used. Specific examples of the component (A) include: nonionic high molecular compounds such as polyvinylpyrrolidone, polyvinyl caprolactam, (vinylpyrrolidone/methacrylamide/vinylimidazole) copolymers, (vinylpyrrolidone/vinyl acetate) copolymers and the like; cationic high molecular compounds such as (vinylpyrrolidone-N/N-dimethylaminoethyl methacrylate) copolymer, polyquaternium-11, polyquaternium-16, polyquaternium-44, polyquaternium-46, polyquaternium-68, polyquaternium-86, polyquaternium-87, etc. These examples may be used only one kind or in combination of two or more kinds. Among them, at least one selected from polyvinylpyrrolidone, polyvinyl caprolactam, (vinylpyrrolidone/methacrylamide/vinylimidazole) copolymer, and (vinylpyrrolidone/vinyl acetate) copolymer, which are nonionic polymer compounds, is preferable from the viewpoint of less influence on hair-dyeing properties.

The blending amount of the component (a) in the hair dye composition is preferably 0.1% by mass or more, more preferably 0.2% by mass or more, and particularly preferably 0.3% by mass or more. When the amount of the component (a) in the hair dye composition is 0.1% by mass or more, the effect of reducing the migration property is high. The amount of the component (a) to be blended in the hair dye composition is preferably less than 5.0% by mass, more preferably 3.0% by mass or less, and particularly preferably 2.0% by mass or less. When the blending amount of the component (a) in the hair dye composition is less than 5.0% by mass, the influence on the hair dyeing property is small, and the transfer property can be reduced while the hair dyeing property is very high.

When the component (a) contains polyvinylpyrrolidone, the K value of polyvinylpyrrolidone is preferably 50 or more and preferably 100 or less. The K value is a viscosity property value related to molecular weight, and can be calculated by applying a relative viscosity value (25 ℃) measured by a capillary viscometer to the following Fikentscher formula.

K＝(1.5logη_rel-1)/(0.15+0.003c)+(300clogη_rel+(c+1.5clogη_rel)²)^1/2/(0.15c+0.003c²)

Further, in the above formula, η_relThe relative viscosity of the aqueous polyvinylpyrrolidone solution to water is shown, and c represents the polyvinylpyrrolidone concentration (%) in the aqueous polyvinylpyrrolidone solution.

When the K value of polyvinylpyrrolidone is 50 or more, the film-forming property of the hair dye composition is improved, and the effect of reducing the migration property is high. When the K value of polyvinylpyrrolidone is 100 or less, the viscosity of the hair dye composition is less increased by blending polyvinylpyrrolidone, and thus it is easy to blend polyvinylpyrrolidone in a required amount. The K value of polyvinylpyrrolidone is more preferably 60 or more, and still more preferably 90 or less. Examples of the raw material of polyvinylpyrrolidone include "Creejus (registered trademark) K-30", "Creejus (registered trademark) K-90", manufactured by Ashland, Inc.

The component (B) is contained in a hair dye composition in a relatively large amount in order to achieve high quick-drying properties. In addition, when a large amount of the component (B) is blended in the hair dye composition, the solubility of the dye can be improved, and the effect of improving the compatibility with the component (C) to improve the stability of the preparation can be obtained.

0.7g of each hair dye composition was applied to a hair strand of human hair (hereinafter, simply referred to as a hair strand) mixed with white hair and having a length of 10cm and a weight of 1g, manufactured by Beaulax corporation, with a brush, and left at 30 ℃ for 5 minutes. Then, the hair tresses were subjected to two treatments with a shampoo (Bigen conditioning shampoo manufactured by friend co., ltd.) and one treatment with a hair conditioner (Bigen conditioning rinse manufactured by friend co., ltd.). Subsequently, the hair bundle is dried to be a hair dyeing treatment hair bundle. With respect to the hair dyeing treatment strand, the hair dyeing ability after the hair dyeing treatment was evaluated in the following manner.

The hair bundles of each example after the hair dyeing treatment were visually observed under a standard light source by 10 inspectors, to thereby judge whether the hair dyeing ability of the hair dye composition of each example was good. The following 5 grades of evaluations were performed: when the number of examiners who answered the hair dyeing ability considered good was 8 or more, "excellent: 5'; the test results were rated "good" when the number of examiners who answered that the hair dyeing ability was good was 6-7: 4 "; when the number of examiners who answer that the hair dyeing ability is considered good is 4-5, the evaluation is "ok: 3 "; the test results were rated "slightly poor" when the number of examiners who answered the hair dyeing ability considered good was 2-3: 2 "; the examiner who answered the hair dyeing ability considered to be good was rated "poor" when the number of persons was 1 or less: 1".

(affinity for Hair)

The substantivity of each hair dye composition to the hair strand when each hair dye composition was applied to the hair strand with a brush was scored by 5 examiners on the following 5 scales: the affinity for hair strand was "excellent (5 points)"; "good (4 points)"; "Can (3 min)"; "slightly inferior (2 min)"; and "difference (1 min)". The average value of the score results of each examiner was calculated, and the score with an average value of 4.6 points or more was "excellent: 5'; the average value of 3.6 points or more and less than 4.6 points was rated as "good: 4 "; the average value of 2.6 points or more and less than 3.6 points was rated as "may: 3 "; the average value of 1.6 points or more and less than 2.6 points was rated as "slightly poor: 2 "; average values less than 1.6 points were rated as "poor: 1".

(migration Property after leaving for a predetermined period of time)

The hair tresses were coated with 0.5g of each hair dye composition with a brush and left at 30 ℃ for 5 minutes. Then, the coated hair tresses were gripped with white cotton cloth (according to JIS L0803) for JIS dyeing fastness test, and a load of 5kg was applied from above the cotton cloth. The degree of staining of the cotton cloth was visually observed after the load was applied for 1 minute, and evaluated according to the following criteria.
