Abstract

PURPOSE:To obtain a hair cosmetic having excellent recovering effect on the hair deformed in bed, effective for improving the smoothness of hair and giving wet feeling to the hair by compounding a quaternary ammonium salt, a polyether compound produced by the addition polymerization of propylene oxide to diglycerol, a propellent and water. CONSTITUTION:The objective hair cosmetic contains 0.05-2wt.% (preferably 0.1-1.0wt.%) of a compound of formula (one or two of R1 to R4 are 12-24C alkyl and the others are 1-3C alkyl or benzyl; X is halogen) (e.g. dimethyl dioctadecyl ammonium chloride), 0.1-3wt.% (preferably 0.2-1.5wt.%) of a polyether compound produced by the addition polymerization of propylene oxide to diglycerol, 2-35wt.% (preferably 4-30wt.%) of a propellent (e.g. dichlorodifluoromethane) and water. The hair cosmetic can be sprayed to the necessary part at a necessary rate to impart the sprayed hair with wet feeling.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to hair cosmetics, and more specifically, the present invention relates to hair cosmetics, and more specifically, it is excellent in the ease of straightening the hair, greatly improves smoothness, and is necessary for use. The present invention relates to a hair cosmetic that can be sprayed in the required amount onto the desired areas and has an excellent wet feeling on the hair after spraying.

[Problems to be solved by conventional techniques and inventions] When it comes to hair style, beauty is one of the important points.
Various beauty treatments are performed.

For example, - As a temporary treatment method, hair is styled using a hair dryer and a planer.
At this time, various hair cosmetics (sesotronoyon, foamy hair cosmetics, hair creams, hair liquids), etc. are used to make it easier to create hairstyles. On the other hand, people have become more conscious of fashionable hair in recent years, and the current situation is that people are spending more time and effort on styling their hair, especially in the morning.

However, when creating a hairstyle in the morning when you are sleeping unevenly, it may not turn out the way you want, and there are many cases where this happens due to sleeping habits.
There is a desire for something that can easily correct sleeping habits and create hairstyles in a short time.

The present invention is excellent in the ease of adjusting the sleeping position, greatly improves smoothness, and allows the necessary amount to be sprayed on the necessary areas, and the hair after spraying is v:! The purpose of the present invention is to provide hair cosmetics that are excellent in wet hair removal.

Means for Solving 3 Problems] The present invention provides (c) - Boatman [In the formula, 1 to 2 of R1 to R4 represent a long chain alkyl group with 12 to 24 carbon atoms, and the remainder represent a long chain alkyl group with 1 to 24 carbon atoms. 3 represents an alkyl group or a hennol group, and X represents )\rogen atom. ] One or more of the quaternary ammonium salts represented by
0.005 to 2% by weight and 0.1 to 3% by weight of a polyether compound obtained by addition polymerization of 15 moles.

The cationic surfactant which is component (A) of the present invention has the following general formula: -3 represents an alkyl group or a Hensyl group, and X represents a halogen atom. ] One or a mixture of two or more quaternary ammonium salts represented by these are applicable.

For example, dimethyldioctadecylammonium chloride, 4-octadecyltrimethylammonium chloride,
Dodenyltrimethylammonium chloride, henzyldimethyloctadecylammonium chloride 2 Benzyldiethyldodecylammonium chloride 5 Didodecyldimethylammonium chloride, hexadecyltrimethylammonium chloride, dodecyltrimethylammonium furomide 2 Tocodyltrimethylammonium chloride, didodecyldimethylammonium furomide, etc. can be mentioned.

The hair cosmetic of the present invention contains, based on the total amount, one or a mixture of two or more of these cationic surfactants.
0.05 to 2% by weight (hereinafter abbreviated as wt%), preferably 0.1 to 1. OW t% is blended. Blend amount is 0
．． If the amount is less than 0.05 wt%, good results for hair smoothness cannot be obtained, and 2. If it exceeds Qwt%, the hair becomes sticky, which is not preferable.

The -thyl compound is a well-known substance, and examples thereof include polyoxypropylene (5) diglyceryl ether, polyoxypropylene (10) diglyceryl ether, polyoxypropylene (15) diglyceryl ether, and the like. If the added mole of propylene oxide is less than 5, there is no effect, and if the added mole is more than 15, the smoothness will be poor, which is not preferable.

The hair cosmetic of the present invention may contain one or a mixture of two or more of these polyether compounds.
．． 1 to 3 wt%, preferably 0.2 to 1.5 Wt
% blended. If the blending amount is less than Q, l w t%,
Good results cannot be obtained in the effect of correcting sleep habits, and if it exceeds 3 wt%, the hair becomes heavy, which is not preferable.

The propellant which is component (C) of the present invention is a propellant usually used in aerosol products, such as dichlorodifluoromethane and trichloromonofluoromethane. ; Freon gas such as chlorotetrafluoroethane, propane, isobutane 1 Normal butane and mixtures thereof 2
, 0kg~6.0kg/cmJat2
Examples include liquefied gas such as liquefied petroleum gas (hereinafter abbreviated as LPG) at a temperature of 5° C.), dimethyl ether, carbon dioxide gas, nitrogen gas, and the like.

The type of propellant used in the hair cosmetic of the present invention is appropriately selected depending on the type of propellant. If the amount is less than 2 wt%, the spray condition will be poor, and if it is less than 35 wt%, the wet feeling on the hair will be reduced, which is not preferable.

As the water which is component (D) of the present invention, ordinary water such as ion-exchanged water and distilled water is used.

Although the above-mentioned four components are essential components of the hair cosmetic composition of the present invention, other components may be appropriately blended into the composition as long as the object of the present invention is achieved. In other words, hydrocarbons such as squalane and liquid paraffin, ester oils such as isopropyl myristate and isopropyl palmitate, vegetable oils such as tsubaki oil, olive oil, and avocado oil, licorice oils such as low boiling point licone and cyclic licorice, polyglycerin fatty acid esters, and polyester oils. Nonionic surfactants such as oxyethylene sorbitan monolaurate, cellulose derivatives such as methylcellulose, hydroxyethylcellulose, and cationized cellulose, humectants such as propylene glycol and glycerin, ethyl alcohol, polypeptides, and other colorants , fragrances, etc., and one or more of these can be blended.

The hair cosmetic composition of the present invention can be applied to a mist-like or foam-like hair cosmetic composition used for straightening hair.
