Description

  The present invention relates to a hair cleansing composition, and specifically to a hair cleansing composition having a conditioning effect that can improve the condition of the hair.

  In women's shampooing behavior, conditioners (or rinses and treatments) are often used to improve the condition of the hair, such as suppressing hairiness after the hair has been cleaned with shampoo. However, only shampoo may be used when there are time constraints or when it is not necessary to take time and effort in bathing with children.

  Therefore, even when only the shampoo is used, various efforts have been made to improve the goodness of the hair when the shampoo is rinsed. Typical examples include those blended with cationized cellulose or cationized guar gum, which are water-soluble polymers (for example, Patent Documents 1, 2, and 3).

  In addition, various approaches have been made to improve the conditioning effect of shampoos, and representative examples include those containing cationized cellulose or cationized guar gum, or those containing a silicone compound (for example, Patent Documents 4 and 5).

  However, since the water-soluble polymers proposed in Patent Documents 1 to 3 cannot provide sufficient effects even in a small amount, it is necessary to add a large amount in order to exhibit these effects. As a result, the hair may become stiff or sticky due to the film-forming properties of the water-soluble polymers such as cationized cellulose and cationized guar gum.

  In addition, the conditioning effects of the shampoo compositions proposed in Patent Documents 4 and 5 are not sufficient, and are particularly unsatisfactory for consumers whose hair is damaged by coloring. This is because silicone, which is a conditioning component, is difficult to adsorb on hair during shampooing, and this tendency is particularly noticeable in hair damaged by coloring or the like. Furthermore, it has already been found that calcium in tap water is adsorbed on the hair, and it is found to be stiff, especially in hair damaged by coloring or the like (Non-patent Document 1).

  Therefore, the present invention solves the above problems, provides good fingering when rinsing with abundant foaming, excellent hair feel after drying, and allows the hair condition to be maintained without using a separate conditioner (or rinse or treatment). An object of the present invention is to provide a hair cleansing composition having a conditioning effect that can be improved.

  As a result of intensive studies, the present inventors have found that (a) at least one anionic interface selected from the group consisting of polyoxyethylene alkyl ether sulfates, alkyl sulfates, alkylbenzene sulfonates and α-olefin sulfonates. A shampoo base comprising an active agent, (b) at least one water-soluble polymer selected from the group consisting of carrageenan, alginic acid, alginic acid salt and fucoidan; and (c) a nonionic surfactant and / or an amphoteric interface. A conditioning component in a hair cleansing composition by blending an active agent and (d) a silicone compound, and further adjusting the pH of the composition to a range of 3.0 to 6.0. It can be seen that the amount of silicone adsorbed on the hair can be improved and the amount of calcium adsorbed on the hair, which is thought to be the cause of the rustling, can be reduced. However, the present invention has been completed.

That is, the hair cleansing composition of the present invention comprises (a) at least one anion selected from the group consisting of polyoxyethylene alkyl ether sulfates, alkyl sulfates, alkylbenzene sulfonates and α-olefin sulfonates. A surfactant,
(B) at least one water-soluble polymer selected from the group consisting of carrageenan, alginic acid, alginate, and fucoidan;
(C) a nonionic surfactant and / or an amphoteric surfactant;
(D) a silicone compound;
And the pH at 25 ° C. is in the range of 3.0 to 6.0.

  According to the present invention, the effect of adsorbing silicone on hair is higher than that of a hair cleansing composition in which cationized cellulose or cationized guar gum, which is a resin component that has been blended in the past, and silicone are combined. Since the amount of adsorption is decreased, the finger of the hair during rinsing is good and the feel of the hair after drying is excellent.

  Further, the conditioning effect can be enhanced by adding an aromatic carboxylic acid and / or salt thereof as component (e) and a cationic surfactant as component (f) to the present composition.

Hereinafter, embodiments of the present invention will be described.
The hair cleansing composition of the present invention comprises (a) at least one anionic interface selected from the group consisting of polyoxyethylene alkyl ether sulfates, alkyl sulfates, alkylbenzene sulfonates and α-olefin sulfonates. An active agent (hereinafter referred to as “component (a)”) and (b) at least one water-soluble polymer (hereinafter referred to as “component (b)”) selected from the group consisting of carrageenan, alginic acid, alginate, and fucoidan. ), (C) a nonionic or amphoteric surfactant (hereinafter referred to as “component (c)”), and (d) a silicone compound (hereinafter referred to as “component (d)”).

  Examples of the component (a) used in the present invention include, for example, polyoxyethylene alkyl ether sulfates, alkyl sulfates, and alkylbenzene sulfonates. As typical examples, the alkyl group includes, for example, an octyl group, a nonyl group, Examples include decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl and the like. In particular, a dodecyl group, a tridecyl group, and a tetradecyl group are preferable. Moreover, the range of the total average addition mole number in especially preferable polyoxyethylene alkyl ether sulfate is 2-4.

If the amount is less than 0.001% by mass, the amount of silicone adsorbed on the hair, which is a conditioning component in the hair cleansing composition, is not improved, and the amount of calcium adsorbed on the hair, which is thought to be a cause of galling, is not recognized so much. There is a tendency that the effect of improving the feel of the hair at the time or after drying is insufficient. On the other hand, when it exceeds 10% by mass, the viscosity of the composition may be remarkably increased or the solution stability may be deteriorated. In addition, since the main objective which mix | blends the component (b) in this invention is as above-mentioned, and it is not making the main objective to raise a viscosity, the lower limit of a preferable compounding quantity is smaller than the case where it uses as a thickener.

Two or more species can be used in appropriate combination. Among these, dimethylpolysiloxane and amino-modified silicone are particularly preferably used. They are because the hair feels better after drying.

  Moreover, as the silicone compound, not only oil, but also an emulsion obtained by emulsifying the silicone compound with a surfactant can be used. In addition, there is no restriction | limiting in particular in an emulsifier and the emulsification method, and such an emulsion can be used variously.
