Definitions

• the present invention relates to a hair cosmetic that is excellent in hair styling power, re-hair styling power, and moisturizing power, and is not stiff.
• hair cosmetics are often used as hair cosmetics for the purpose of styling hair.
• these hair cosmetics contain a film-forming agent such as a water-soluble polymer in order to obtain sufficient hair-styling retention power.
• the hair-styling retention power decreases due to moisture absorption over time or the film-forming agent. Problems such as flaking due to solidification of powder and difficulty in re-styling hair have been pointed out.
• Patent Document 1 in a gel-like hair dressing containing an alkali thickener and an alkali agent, a nonionic resin comprising 0.5 to 7.5% by weight of a vinylpyrrolidone copolymer is used.
• Patent Document 2 contains a water-soluble polymer, at least one selected from glycerin, saccharides, polyalkylene glycol and / or derivatives thereof, and 1,2-alkanediol having 5 to 10 carbon atoms.
• a hair cosmetic composition is disclosed, which suppresses stickiness and film feeling and is superior in texture.
• Patent Document 3 describes a waxy hair styling agent containing a vinyl pyrrolidone film forming agent, a cationic surfactant, a higher alcohol and glycerin and / or polyglycerin, and imparts the original hair styling power of the film forming agent. It is said that it suppresses a reduction in hair holding ability and is excellent in moisture resistance.
• hair styling agents such as those described in Patent Documents 1 to 3 are not sufficient in hair styling ability and style holding power even if the moisture retention is improved by blending glycerin, propylene glycol or the like.
• the subject in this invention is providing the hair cosmetics which have the hair styling power and re-hair styling power which were superior to the conventional hair styling agent, and the set holding
• the present inventors combined diglycerin and sugar alcohol with a resin, and adjusted their blending amounts within a specific range to achieve the desired characteristics. The present inventors have found that a hair cosmetic composition having a hair color can be obtained, and have completed the present invention.

• a hair cosmetic characterized in that the content is% by mass.
• the hair styling ability was improved by blending resin, diglycerin, and sugar alcohol in a predetermined blending amount, and further blending a water-soluble thickener.
• the moisturizing effect over time is improved compared to cosmetics blended with glycerin and propylene glycol used in the prior art, and the resin does not solidify completely. Re-hairdressing became possible.
• Diglycerin (component A) to be blended in the hair cosmetic composition of the present invention accounts for 5 to 30% by mass, preferably 5 to 25% by mass, more preferably 5 to 20% by mass of the total composition. If the blending amount is less than 5% by mass, sufficient moisturizing power cannot be obtained, the hair becomes stiff and re-styling may become difficult. When it mixes exceeding 30 mass%, stickiness will be produced and it will become a heavy touch, a style holding power may fall and it may become difficult to re-hair.
• the sugar alcohol (component B) blended in the hair cosmetic composition of the present invention has an action of improving the moisturizing power in cooperation with the diglycerin.
• hair cosmetics containing both diglycerin and sugar alcohol at the same time have not been known.
• the sugar alcohol used in the present invention is not particularly limited, but for example, one or more selected from sorbitol, maltitol, and mannitol are preferably used.
• Commercially available products may be used, and examples thereof include Sorbit 70S (trade name), Mabit (trade name), D-Mannit (trade name), and the like.
• the blending amount of the sugar alcohol in the hair cosmetic composition of the present invention is 5 to 25% by mass, preferably 5 to 20% by mass.
• the blending amount is less than 5% by mass, the hair styling power and the style holding power are lowered, and sufficient hair retention power is not exhibited, so that re-hair styling may be difficult. If the blending amount exceeds 25% by mass, the hair styling power and the style holding power are also lowered, which may cause wrinkles.
• the resin (component C) blended in the hair cosmetic composition of the present invention is a polymer resin corresponding to a water-soluble polymer or film forming agent blended in a conventional hair cosmetic composition (hairdressing agent).
• a conventional hair cosmetic composition hairdressing agent
