Description

  The present invention relates to a hair styling composition that has good setting power and can suppress stickiness of hair after application.

  Conventionally, hair preparations using waxes and solid esters have been known to ensure the function of preparing hairstyles (Patent Documents 1 and 2, etc.), and waxes to further enhance the setting power. Hair styling compositions comprising a combination of a solid ester and various polymers are also known (Patent Documents 3 to 6, etc.).

  However, if a hair styling agent comprising a combination of waxes or solid esters and a polymer is applied to the hair, it becomes sticky and tends to clump together in multiple bundles, making it difficult to form a desired hairstyle. There is. Therefore, there is a need for the development of a hair styling agent that can increase the setting power and also suppress the stickiness of the hair.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hair styling composition that has good setting power and can suppress stickiness of the hair after application.

  As a result of intensive studies, the inventors of the present invention have modified starch with a specific structure by combining it with a specific amount of wax or a solid ester at 25 ° C. to increase the setting power and make the hair sticky after application. It was found that a hair styling composition that can easily form a desired hairstyle can be formed with a reduced hair pressure.

  That is, the hair styling composition of the present invention that has achieved the above-mentioned object is formulated with at least waxes or an ester that is solid at 25 ° C. and hydroxypropyl-modified starch, and waxes or solid at 25 ° C. The blending amount of the ester is 0.1 to 10% by mass, and it has a form of an oil-in-water emulsion.

  ADVANTAGE OF THE INVENTION According to this invention, the hair-styling composition which has favorable set power and can suppress the stickiness of the hair after application | coating can be provided.

  Examples of the waxes related to the hairdressing composition of the present invention include beeswax, candelilla wax, whale wax, carnauba wax, rice bran wax, lanolin, molefish, etc., and only one of these may be used, Two or more kinds may be used in combination. Examples of the solid ester at 25 ° C. according to the hairdressing composition of the present invention include cetyl palmitate, myristyl myristate, cetyl lactate, myristyl lactate and the like, and only one of them is used. Or two or more of them may be used in combination. Moreover, you may use together said wax and solid ester at 25 degreeC for the hairdressing composition of this invention. Among the waxes exemplified above, beeswax, candelilla wax, and whale wax are more advantageous in that the effect of improving set power by combining with hydroxypropyl-modified starch and the effect of suppressing stickiness of hair after application are better. preferable. Among the esters solid at 25 ° C. exemplified above, cetyl palmitate is more preferable because it can further improve the stability of the oil-in-water emulsion.

  Blending amount of waxes or solid ester at 25 ° C. in hair styling composition (when waxes are combined with solid ester at 25 ° C., the total amount thereof. Blending of waxes or solid ester at 25 ° C. The same applies hereinafter for the amount) from the viewpoint of ensuring a good effect (especially an effect of improving the setting force) by the use, and is preferably 0.1% by mass or more and preferably 1% by mass or more. However, as the amount of waxes or solid esters at 25 ° C. increases, the effect of suppressing the stickiness of hair tends to be reduced, so the incorporation of waxes or solid esters at 25 ° C. in hairdressing composition The amount is 10% by mass or less, and preferably 5% by mass or less.

  As the hydroxypropyl-modified starch used in the hairdressing composition of the present invention, “AMAZE (trade name)” marketed by Akzo Nobel Co., Ltd. can be used. This hydroxypropyl-modified starch is a modified product of corn starch and has the structure shown below.

（なお、上記構造式中、Ｒは、トウモロコシデンプン由来の構造部分である。）

(In the above structural formula, R is a structural portion derived from corn starch.)

  The compounding amount of the hydroxypropyl-modified starch in the hairdressing composition is 0.05% by mass or more from the viewpoint of favorably ensuring the effect of its use (the effect of suppressing the stickiness of the hair after application while increasing the setting power) It is preferable that it is 0.1 mass% or more. However, when a hairdressing composition containing too much hydroxypropyl-modified starch is applied to the hair, the wet state continues for a long time, and it takes time to set. Therefore, the blending amount of hydroxypropyl-modified starch in the hairdressing composition is preferably 5% by mass or less, and more preferably 3% by mass or less.

  The hairdressing composition of the present invention has the form of an oil-in-water (O / W) emulsion, and water is the main medium. Note that only water may be used as the medium. If necessary, an organic solvent such as a lower alcohol (alcohol having 6 or less carbon atoms) such as ethanol and isopropanol may be used in an amount of about 20% by mass or less in the total amount of the medium. May be used in combination with water. Moreover, it is preferable that the compounding quantity of the medium in a hairdressing composition is 40-90 mass%, for example.

  Moreover, it is preferable that the hairdressing composition of this invention is mix | blended with the emulsifier for the reason of maintaining the form of an O / W type emulsion stably. Examples of the emulsifier include a surfactant.

As the cationic surfactant, for example, only one type may be used from the above examples, or two or more types may be used in combination.

  The blending amount of the surfactant in the hairdressing composition is preferably 0.5% by mass or more, and more preferably 2% by mass or more, from the viewpoint of ensuring a good effect due to its use. However, if the amount of the surfactant in the hairdressing composition is too large, the scalp may become irritated and the effect of suppressing the stickiness of the hair may be reduced. Therefore, it is preferable that the compounding quantity of surfactant in a hairdressing composition is 10 mass% or less, and it is more preferable that it is 7 mass% or less.

Alkali; hydroxides of alkali metals (potassium hydroxide, sodium hydroxide, etc.), inorganic alkalis such as ammonia;

  The said fatty acid salt can be formed by mix | blending a fatty acid and an alkali in a hairdressing composition. Therefore, when using the said fatty acid salt as an emulsifier of a hairdressing composition, what is necessary is just to prepare a hairdressing composition using a fatty acid and an alkali. In addition, the fatty acid mix | blended with a hairdressing composition may be only 1 type in the thing of the said illustration, and 2 or more types may be sufficient as it. Further, the alkali to be blended in the hairdressing composition may be only one of the above examples, or may be two or more.

  The blending amount of the fatty acid in the hairdressing composition is preferably 0.5% by mass or more, more preferably 2% by mass or more, from the viewpoint of favorably securing the effect of the fatty acid salt formed from the alkali. preferable. However, if the amount of fatty acid blended in the hair styling composition is too large, the effect of suppressing the stickiness of the hair is reduced, and the touch tends to be poor. Therefore, the blending amount of the fatty acid in the hairdressing composition is preferably 10% by mass or less, and more preferably 5% by mass or less.

  Further, the blending amount of the alkali in the hairdressing composition is preferably 0.01% by mass or more, and preferably 0.1% by mass or more from the viewpoint of favorably ensuring the effect of the fatty acid salt formed from the fatty acid. More preferably. However, if the amount of alkali added to the hairdressing composition is too large, the scalp may become irritated. Therefore, it is preferable that the compounding quantity of the alkali in a hairdressing composition is 4 mass% or less, and it is more preferable that it is 2 mass% or less.

  Moreover, you may use together said surfactant and said fatty acid salt for the emulsifier which concerns on a hairdressing composition.
