JP5550259B2 - Cosmetic composition for hair - Google Patents

Description

  The present invention relates to a cosmetic composition for hair having good stickiness and operability when applied to hair, and having excellent setting power.

  Currently, there are various hair styling products in the cosmetics market such as liquid, cream, mist, foam, and spray, and the dosage form is appropriately selected according to the application. Among such hair styling products, those having high hair styling power (setting power) include hair waxes and hair creams. Such hair styling materials include solids with high hardness such as waxes and waxes. Often, the oil component is added.

  However, if the amount of waxes or waxes is increased to improve the setting power of the hairdressing agent, for example, the viscosity of the hairdressing agent will increase, resulting in stickiness on the hair after application or operability of the hair after application. There was a problem that became worse.

  For these reasons, in hair styling compositions containing waxes and waxes, studies have been made to improve the setting power while suppressing the stickiness and operability of the hair after application (for example, Patent Documents 1 to 3). .

  On the other hand, generally, nonionic surfactants and anionic surfactants are often used in emulsified cosmetic compositions. For example, alkyloyl lactic acid ester salts that are nonionic surfactants contain oily components. It is known as a component that can be stably dispersed in water (Patent Document 4), and there is also a proposal of a cosmetic composition that suppresses stickiness of hair after application while blending this (Patent Document 5).

JP-A-10-45546 JP 2004-91407 A JP 2007-153770 A JP 2000-256188 A JP 2004-196749 A

  Thus, when a hair styling composition is composed of a combination of waxes or waxes and an alkyloyl lactic acid ester salt, for example, it is expected that improvement in setting power can be achieved while suppressing stickiness of the hair after application. According to these studies, it has been found that even if these are simply used in combination, the setting power is not improved, and the stickiness of the hair after application and the decrease in operability cannot be sufficiently suppressed.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cosmetic composition for hair having good stickiness and operability of the hair after application and having excellent setting power. There is to do.

  As a result of further studies to improve the setting power of the cosmetic composition for hair and to suppress the stickiness of hair after application and the decrease in operability associated therewith, a specific wax has been obtained. It has been found that this can be achieved by combining a class with a specific acyl lactate, and the present invention has been completed.

  That is, the hair cosmetic composition of the present invention that has achieved the above object is characterized in that at least candelilla wax and a branched acyl lactate are blended.

  ADVANTAGE OF THE INVENTION According to this invention, the non-stickiness of hair after application | coating and operability are favorable, and the cosmetic composition for hair which has the outstanding setting power can be provided.

  In the hair cosmetic composition of the present invention, candelilla wax is used. As described above, various types of waxes and waxes are known as ingredients for enhancing the setting power of a cosmetic composition for hair, but these usually cause the hair after application to be sticky or the hair after application. It may reduce the operability. However, if it is a candelilla wax, the cosmetic composition for hair is combined with a branched acyl lactate which will be described later, thereby improving the setting power while suppressing the stickiness and operability of the hair. Can do.

  The blending amount of the candelilla wax in the hair cosmetic composition may be 0.1% by mass or more from the viewpoint of better securing the effect (especially the effect of improving the setting power) by using the candelilla wax. Moreover, since the improvement with time of the viscosity stability of the cosmetic composition for hair is expected, it is more preferably 0.5% by mass or more. However, if the amount of candelilla wax in the hair cosmetic composition is too large, the setting force becomes too strong, and there is a possibility that the effect of suppressing the stickiness and operability of the hair after application may be reduced, and The elongation of the cosmetic composition for hair becomes worse, and there is a possibility that it will be easily caught when applied to the hair. Therefore, the blending amount of candelilla wax in the cosmetic composition for hair is preferably 10% by mass or less, and more preferably 5% by mass or less.

  In the hair cosmetic composition of the present invention, a branched acyl lactate is used. For example, even if only a linear acyl lactate is combined with candelilla wax to constitute a hair cosmetic composition, the setting power is not sufficiently improved. However, in a cosmetic composition for hair composed of a branched acyl lactate combined with candelilla wax, the set power is improved while suppressing stickiness of the hair after application and a decrease in operability.

  Examples of the branched acyl lactate used in the hair cosmetic composition of the present invention include sodium salts of branched acyl lactic acid such as sodium isostearoyl lactate and sodium 12-hydroxystearyl lactate. As the branched acyl lactate, only one of the above-exemplified examples may be used, or a plurality of types may be used in combination. Among these, isostearoyl sodium lactate is more preferable because the effects required in the present invention can be secured satisfactorily and acquisition is easier.

  The blending amount of the branched acyl lactate in the hair cosmetic composition is preferably 0.2% by mass or more, more preferably 0.5% by mass or more, from the viewpoint of ensuring a better setting power improvement effect. More preferably it is. However, if the amount of the branched acyl lactate in the cosmetic composition for hair is too large, the setting power becomes too strong, and there is a risk that the hair after application will become stiff, and for emulsified hair. In the case of a cosmetic composition, emulsification may be difficult. Therefore, the blending amount of the branched acyl lactate in the cosmetic composition for hair is preferably 5% by mass or less, and more preferably 3% by mass or less.

  In the cosmetic composition for hair of the present invention, water is mainly used as a medium. It is preferable that the compounding quantity of the water in the cosmetic composition for hair is 40-90 mass%.

  In addition to the candelilla wax and the branched acyl lactate, the hair cosmetic composition of the present invention preferably contains a microcrystalline wax. By blending the microcrystalline wax, the appearance of the hair cosmetic composition can be improved.

  The blending amount of the microcrystalline wax in the hair cosmetic composition is preferably 0.5% by mass or more, more preferably 1.0% by mass or more, from the viewpoint of better ensuring the effect of its use. More preferred. However, if the amount of the microcrystalline wax is too large, the effect of suppressing the stickiness of the hair may be reduced. Therefore, the blending amount of the microcrystalline wax in the hair cosmetic composition may be 10% by mass or less. Preferably, it is 5 mass% or less.
