Description

  The present invention relates to a hair cosmetic that is excellent in refreshing feeling and sustainability of the refreshing feeling, and further improves usability by suppressing the occurrence of cracks during use.

  Various products such as cosmetics, toiletries, and pharmaceuticals used for scalp and hair are required to have a function that can provide a refreshing feeling for a certain period of time immediately after use in addition to the functions originally required for the product. Various products with such functions are commercially available.

  Conventionally, various cooling agents such as various menthol derivatives such as l-menthol, camphor, spearmint, and peppermint have been proposed in order to improve the refreshing feeling or to maintain the refreshing feeling. In order to further enhance the cooling sensation effect, for example, studies have been made to improve the cooling sensation effect by combining two or more types of cooling sensation agents, or a combination of a cooling sensation agent and a substance other than the cooling sensation agent. Has been proposed to use a menthol derivative and vanillyl butyl ether in order to improve the cooling sensation effect and maintain the cooling sensation (see, for example, Patent Document 1: Japanese Patent Laid-Open No. 2000-44924). Furthermore, a technique for improving the refreshing feeling at the time of washing hair and body and improving the cooling feeling after washing by using menthol, Np-menthane-3-carboxamide, and vanillyl butyl ether has been proposed. (Japanese Unexamined Patent Application Publication No. 2005-8535).

  However, when a preparation containing these cooling sensitizers is used in an application in which it is not washed out immediately after use, in particular, if it is used for spraying on the head, a problem such as peeling off immediately after use occurs, so that it is still satisfactory. There has been a demand for a hair cosmetic composition that has not been obtained and that has improved the skin immediately after use.

JP 2000-44924 A JP 2005-8535 A

  The present invention has been made in view of the above circumstances, and has an excellent refreshing feeling and a refreshing effect of refreshing feeling, and also provides a hair cosmetic having an excellent feeling of use by suppressing the peeling immediately after use. Objective.

  As a result of intensive studies to achieve the above object, the inventor of the present invention used (A) 1-menthol, (B) vanillyl butyl ether, and (C) a specific oleic acid derivative to produce a refreshing feeling and It has been found that the persistence of the refreshing feeling is improved, and further, it is possible to suppress the dullness when used on the hair, and the present invention has been made.

Therefore, this invention provides the hair cosmetics which are the spray agent of the type which contains the following (A)-(D) component and does not wash away immediately after use .
(A) l-menthol (B) vanillyl butyl ether (C) ester of oleic acid and alcohol having 1 to 5 carbon atoms, polyoxyethylene oleyl ether having an average polyoxyethylene addition mole number of 1 to 5, and oleyl alcohol Or two or more oleic acid derivatives (D) ethanol selected from esters of hydrazine and hydroxy acid

  ADVANTAGE OF THE INVENTION According to this invention, while being excellent in the refreshing feeling and the sustainability of a refreshing feeling, the hair cosmetics which have the outstanding usability | use_condition can be provided by suppressing generation | occurrence | production of the crack at the time of use.

The hair cosmetic composition of the present invention comprises (A) 1-menthol, (B) vanillyl butyl ether,
(C) One type selected from esters of oleic acid and alcohols having 1 to 5 carbon atoms, polyoxyethylene oleyl ethers having an average polyoxyethylene addition mole number of 1 to 5, and esters of oleyl alcohol and hydroxy acids or It contains two or more oleic acid derivatives and (D) ethanol.

  As the 1-menthol of the component (A), those obtained by synthesis or those obtained from natural products can be used, and these can be used alone or in combination of two or more. The blending amount of the component (A) is preferably 0.001 to 2.0% by mass (hereinafter simply referred to as “%”) with respect to the total amount of the hair cosmetic, and more preferably 0.01 to 1.0%. is there. If the blending amount is less than 0.001%, a satisfactory refreshing feeling and penetrating sensation may not be expressed, and even if blending over 2.0%, the irritation may be strengthened. The above effects are not exhibited.

  The component (B) is vanillyl butyl ether, and its blending amount is preferably 0.001 to 0.5%, more preferably 0.01 to 0.05%, based on the total amount of the hair cosmetic. If the blending amount is less than 0.001%, a satisfactory refreshing sensation sustaining effect may not be obtained, and if it exceeds 0.5%, the irritation may be enhanced.

(C) component is (C-1) ester of oleic acid and C1-C5 alcohol, (C-2) polyoxyethylene oleyl ether whose average polyoxyethylene addition mole number is 1-5, and ( C-3) One or more oleic acid derivatives selected from esters of oleyl alcohol and hydroxy acid.

(C-3) Examples of esters of oleyl alcohol and hydroxy acid include oleyl lactate, dioleyl malate, trioleyl citrate, and the like.

  (C) Although the compounding quantity of a component changes with the types and the types of a formulation, 0.01 to 15% is preferable with respect to the hair cosmetics whole quantity, More preferably, it is 0.1-10. %. If the blending amount is less than 0.01%, a satisfactory refreshing feeling may not be obtained, and even if blending more than 10%, there is usually no difference in the effect, but at the time of use It may cause stickiness.

  Component (D) is ethanol, and any of those obtained by synthesis or obtained by fermentation can be used, and these can be used alone or in combination of two or more. (D) As for the compounding quantity of a component, 30% or more is preferable with respect to the hair cosmetics whole quantity, More preferably, it is 50% or more. When the blending amount is less than 30%, it takes time to dry the hair and scalp, and stickiness may occur. The upper limit of the amount of ethanol blended is not particularly limited, but is 95%.

  The hair cosmetic composition of the present invention contains the above components (A) to (D), but the blending ratio that maximizes the synergistic effect of each component is represented by (A) / (B). The mass ratio between the component (A) and the component (B) is preferably in the range of 50/1 to 1/1, more preferably 20/1 to 4/1.
