JPH1095715A - Cosmetic agent for hair - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a cosmetic agent for hair which possesses unsticky, unfettered usability, affords soft touch and gives no greasiness and creak to hair by formulating a specific natural plant component thereto. SOLUTION: This material is prepared by formulating unsaturated aliphatic alcohols which consist of carbon atoms of 14-24 containing one double bond. As the unsaturated aliphatic alcohols, e.g. jojoba alcohol, 2- tetradecenol-1(cis)(C14 ), 2-pentadeccenol-1(cis)(C15 ) and 2-heptadecenol-1(cis)(C17 ) are illustrated. Particularly preferable sybstabce is jojoba alcohol. The unsaturated aliphatic alcohols are formulated in an amount of 0.1-50.5wt.%, preferably about 1.0-25.0wt.%, based on the whole amount of the cosmetic material for hair. The cosmetic material for hair is usable as e.g. aerosol type spray, pump style hair spray, foam aerosol, set-lotion and hair oil.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic which imparts smooth feel and suppleness to hair.

[0002]

2. Description of the Related Art Conventionally, oils such as silicone oils, ester oils, hydrocarbon oils and the like have been solubilized, emulsified, or dissolved in hair cosmetics in order to impart gloss and smoothness to the hair. . Among oils, silicone oils are particularly widely used in recent years because they have low surface tension, are excellent in adjusting to hair, and have good gloss.

[0003]

However, in recent years,
From the viewpoint of environmental protection, there has been a demand for a safer natural plant-based component that can impart gloss and smoothness to hair without using silicone oil. Therefore, an object of the present invention is to solve the above-mentioned problems, to provide a sticky use that is not sticky as compared with or more than the case of using silicone oil, and to impart a smooth feel, An object of the present invention is to provide a hair cosmetic using a natural plant-based component which does not cause greasy or squeaky hair.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies to achieve the above object, and as a result, if a hair cosmetic was prepared using jojoba alcohol which is derived from natural plants and which is also biodegradable, The inventors have found that the above object can be achieved, and have completed the present invention based on this finding.

[0005] That is, the present invention is a hair cosmetic comprising an unsaturated aliphatic alcohol having one double bond and 14 to 24 carbon atoms.

Hereinafter, the configuration of the present invention will be described in detail. Used in the present invention have one double bond, the unsaturated aliphatic alcohol having a carbon number of 14 to 24, for example, jojoba alcohol, 2-tetradecenol _{-1 (cis) (C 14)} , 2 Pentadecenol-1 (ci
s) (C _14), 2- Heputadesenoru -1 (cis)
(C ₁₇ ), 2-octadecenol-1 (cis)
( _C18 ), 2-octadecenol-1 (trans)
(C _18), 15- hexadecenol -1 (C _16), and the like. Aliphatic alcohols without double bonds have insufficient lubrication. When the number of carbon atoms is less than 14, creaking occurs, and when the number of carbon atoms exceeds 24, stickiness is felt.

Particularly preferred among the unsaturated aliphatic alcohols are jojoba alcohols. Jojoba alcohol refers to an alcohol obtained by reducing oil obtained from dried seeds of Jojoba (Jojoba; Simmondsia chinensis) with metallic sodium, and its composition is octadecenol (C ₁₈ ), eicosenol (C ₂₀ ), docosenol (C
₂₂ ) and tetracosenol (C ₂₄ ), which is represented by the following general formula (1).

(Wherein, m = 7, 9, 11, 13) The jojoba alcohol is NIKKOL jojoba alcohol (manufactured by Nikko Chemicals Co., Ltd.) or jovacaol (manufactured by Koei Kogyo Co., Ltd.).
It is marketed as The present invention may be any of a dissolving system, a solubilizing system, and an emulsifying system of an unsaturated aliphatic alcohol, but it is an emulsified hair cosmetic from the viewpoint of imparting a stable blend to a product system and imparting particularly smoothness. Is preferred.

The amount of the unsaturated aliphatic alcohol used in the present invention is 0.1 to 5 in the total amount of the hair cosmetic composition of the present invention.
It is 0.0% by weight, preferably 1.0 to 25.0% by weight. If the amount is less than 0.1% by weight, a sufficient effect cannot be obtained in terms of imparting gloss and smoothness to hair, and if the amount exceeds 50.0% by weight, the effect of the present invention is not enhanced. .

Further, the hair cosmetic of the present invention may contain, in addition to the above essential components, other optional components as long as the effects of the present invention are not impaired.
