Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a formulation containing one or more water-soluble chitin derivatives and one or more sulfosuccinate salt type surfactants represented by the following general formula. The present invention relates to a composition for skin and hair that is characterized by having excellent usability and stability by blending two or more types.

General formula (A) M 100 CCHS O3M 2 ROOCCH2 (wherein R is a straight or branched alkyl group or alkenyl group having 8 to 22 carbon atoms, or a combination of these groups and polyoxyethylene or/and polyoxy (Represents a propylene ether group, and M, M2 represent alkali metals, organic amines, and basic amino acids.) [Prior art] Shells of crustaceans such as crabs and shrimps, exoskeletons of insects, or bacteria, Chitin and its derivatives, which exist in the cell walls of algae, are attracting attention as naturally occurring polymeric substances with excellent moisturizing and skin and hair protection effects, and as raw materials for skin and hair compositions. It has poor compatibility and is difficult to dissolve uniformly in skin and hair compositions. Therefore, although chitin and its water-soluble derivatives are expected to have excellent moisturizing and skin and hair protective effects when incorporated into skin and hair compositions, their actual use has been difficult.

[Problems to be Solved by the Invention] In view of the above circumstances, the inventors of the present invention have conducted intensive research and found that in the formulation, the general formula (A) M 100 CCHS O3M 2 ■ ROOCCH2 (in the formula, R has 8 carbon atoms) to 22 linear or branched alkyl groups or alkenyl groups, or these groups and polyoxyethylene or/and polyoxypropylene ether groups, Ml and M2 represent alkali metals, organic amines, and basic amino acids. If one or more water-soluble chitin derivatives are blended with one or more sulfosuccinate salt type surfactants represented by the following formula, skin and hair compositions with excellent usability and stability can be obtained. The present invention was completed based on the discovery that the following can be obtained.

[Means and effects for solving the problems] That is, the present invention includes one or more water-soluble chitin derivatives and one or more sulfosuccinate salt type surfactants represented by the above general formula in the formulation. The object of the present invention is to provide a composition for skin and hair that is characterized by containing two or more types and has excellent usability and stability.

Hereinafter, the configuration of the present invention will be explained in detail. In the following description, the composition for skin and hair will be simply referred to as a composition.

The water-soluble chitin derivatives used in the present invention are derived from chitin present in the shells of crustaceans such as crabs and shrimps, the exoskeletons of insects, and the cell walls of bacteria and algae. An example of this is chitosan, which is a deacetylated product of chitin.

As a specific example of obtaining chitosan, crab and shrimp shells are treated with dilute hydrochloric acid to decalcify and then treated with dilute sodium hydroxide solution to deproteinize. The obtained crude chitin is washed with water, purified if necessary, and then deacetylated with a concentrated sodium hydroxide solution.

The obtained crude chitosan is washed with water and, if necessary, purified to obtain chitosan.

Chitin itself is generally insoluble in water, but chitin treated by certain methods is water-soluble. That is, the degree of deacetylation is 4 as exemplified in JP-A No. 53-47479.
It is 0-60% water soluble partially deacetylated chitin. This water-soluble partially deacetylated chitin can also be used in the present invention.

Furthermore, chitin made water-soluble by introducing substituents, such as carboxymethyl chitin with carboxymethyl groups introduced, glycolated chitin, and chitin sulfate, can also be applied to the present invention.

Chitin is usually a polymer with a molecular weight of 1,000,000 or more, but the molecular weight of its derivatives decreases during the treatment process, and it is not uncommon for chitin to have a molecular weight of several hundred thousand.

The water-soluble chitin derivative used in the present invention can range in molecular weight from a natural one of 1,000,000 or more to a low molecular weight one.

In the present invention, the amount of the water-soluble chitin derivative blended is 0.001 to 1'-0% by weight (hereinafter simply referred to as %).
If the level is 0.001% or less, the effects of the present invention cannot be achieved. If it exceeds 10%, the solubility of the water-soluble chitin derivative exceeds the solubility of the water-soluble chitin derivative, making it difficult to prepare a composition.

The amount that can be blended to achieve the effects of the present invention is preferably 0.01 to 1%.

Further, even if a small amount of an acidic substance is added together with the water-soluble chitin derivative for the purpose of dissolving the water-soluble chitin derivative according to the present invention, the effects of the present invention will not be inhibited.

For example, for the purpose of dissolving chitosan, the effects of the present invention remain unchanged even if hydrochloric acid is used in an amount equivalent to the weight of chitosan.

On the other hand, the sulfosuccinate salt type surfactant used in the present invention has the general formula (A) M, OOCCHS 03M2 ■ ROOCCH2 (wherein R is a straight or branched alkyl group having 8 to 22 carbon atoms or It represents an alkenyl group, or a polyoxyethylene or/and polyoxypropylene ether group, and M1 and M2 represent an alkali metal, an organic amine, or a basic amino acid.

According to the present invention, the amount of the sulfosuccinate salt type surfactant mixed into the composition together with the water-soluble chitin derivative is 0.01 to 50%, preferably 0.1 to 3%.
It is 0%.

As the composition base in which the water-soluble chitin derivative and sulfosuccinate salt type surfactant are blended according to the present invention, common composition bases in the form of liquid, cream, emulsion, paste, etc. can be used. In addition, the technology according to the present invention can be applied to moisturizing creams, emulsified essences, shampoos,
It can be applied to hair treatments, body cleanser-1 facial cleansing paste, facial cleansing lotion, etc.

In addition to purified water, a humectant can also be added to the base of these compositions, if necessary.

Examples include glycerin, 1,3-butylene gellicol, propylene glycol, dipropylene glycol, sorbitol, maltitol, hyaluronic acid, chondroitin sulfate, and polyethylene glycol.

Oils include liquid paraffin, squalane, petrolatum,
Hydrocarbons such as solid paraffin, olive oil, jojoba oil,
Natural oils such as evening primrose oil, coconut oil, beef tallow, ester oils such as isopropyl myristate, pentaerythritol-tetra-2-ethylhexanoate, cetyl isooctanoate, silicone oils such as methyl silicone, methylphenyl silicone, cetyl Alcohol, higher alcohols such as oleyl alcohol and behenyl alcohol, fatty acids such as stearic acid, behenic acid, palmitic acid, myristic acid, lauric acid, oleic acid, isostearic acid, etc.
etc. can also be used together.

As the surfactant, those that can be generally incorporated into the composition can be used.

Nonionic ones include POE alkyl ether,
Common examples include POE branched alkyl ether, POE sorbitan ester, POE glycerin fatty acid ester, POE cured castor sorbitan ester, glycerin fatty acid ester, polyglycerin fatty acid ester, and the like.

Common anionic compounds include fatty acids, acylglutamic acids, alkyl sulfates, alkyl phosphoric acids, potassium, sodium, triethanolamine and basic amino acid salts of alkyl sulfonic acids, and POE alkyl borates.

Even if vitamins, anti-inflammatory agents, bactericidal agents, activators, ultraviolet absorbers, chelating agents, buffers, preservatives, etc. that stabilize the composition are added to the zara, the effects of the present invention will be inhibited. It's not something you do.

It goes without saying that ingredients that normally modify the composition, such as dyes and fragrances, can be used in combination.

Next, the present invention and the effects of the present invention will be explained in detail with reference to Examples and Comparative Examples, but the present invention is not limited thereto.

This is an example in which the compound is blended with the following, and has excellent storage stability and usability, which are the effects of the present invention.

On the other hand, Comparative Examples 1 and 2 are examples in which a water-soluble chitin conductor and other surfactant were blended, and a case in which a water-soluble chitin derivative was not blended.

Comparative Example 1 contained a surfactant other than the one according to the present invention together with a water-soluble chitin derivative, so it had poor stability over time, and there was a precipitate when stored at room temperature along with the sample of Example 1. The remarkable difference in storage stability between Example 1 and Comparative Example 1 is an effect of the present invention.

On the other hand, in terms of usability, 20 beauty technicians were asked to use the samples of Example 1 and Comparative Example 2 about their suppleness after use, and were asked to choose the sample with excellent suppleness. An overwhelmingly large number of respondents answered that the sample was excellent.

Comparative Example 2 is inferior in usability compared to Example 1, but this is because the technology according to the present invention is not applied, and Example 1 according to the present invention is also superior in usability. . When asked about those who answered that Comparative Example 2 was better, they complained that their skin was severely rough and their sense of use was somewhat numb.

To prepare the sample of Comparative Example 3, each component was heated to 70°C.
When mixed under heating, it did not dissolve uniformly and separated into two phases.
A hair cleansing material that could withstand use could not be obtained. This is because a surfactant other than the one according to the present invention was used.

On the other hand, in Example 1, when each component was mixed at 70°C, a semitransparent and uniform hair cleansing material was obtained.
The properties after storage were similar to those immediately after preparation. This is an effect of blending the sulfosuccinate salt type surfactant with the water-soluble chitin conductor according to the present invention. - <Comparative Example 4> Hair cleansing material Sulfosuccinic acid ester salt type 30wt% surfactant (Note-1) Propylene glycol 3 Coconut oil diethanolamide 2 Preservative
