Description

  The present invention relates to a non-aqueous hair cosmetic. More specifically, the present invention relates to a non-aqueous hair cosmetic that is transparent in appearance, and excellent in spreading and spreading to hair, and is excellent in giving a solid, glossy, firm feeling and moist feeling.

  In recent years, with the spread of chemical treatments such as hair dyeing and permanent wave, damage to hair has increased. Hair that has undergone such chemical treatment is brittle and is subject to multiple effects such as shampooing, ultraviolet rays, and brushing in daily life, causing severe damage such as peeling of hair cuticles and split ends. Damaged hair is not smooth and slippery, and the touch feeling such as crispness, stiffness, and squeakiness also deteriorates. It is difficult to obtain a sufficient effect only by using a hair care material that is washed away with water such as hair rinse or hair treatment for hair having such a large damage. Therefore, hair treatment materials of a type that does not wash away, particularly oil-type hair cosmetics, have been proposed (Patent Documents 1 to 6).

  These oil-type hair cosmetics are intended to supplement the hair with oil and give it a gloss, moist feeling, flexibility, etc. Oils such as various silicone compounds, hydrocarbons, animal and vegetable oils, ester oils, fatty acids, etc. Used as the main component.

  However, some of the above oils have limited compatibility with the combination and blending ratio, and the blending amount into the non-aqueous hair cosmetic is limited due to poor compatibility, non-uniformity, and white turbid appearance. is there. When ingredients with poor compatibility are used, non-aqueous hair cosmetics are not only unstable over time, but also adhere unevenly to the hair, so it is easy to feel badness and stickiness on the fingers and combs. This causes the problem.

  In particular, vegetable oils mainly composed of triglycerides used for the purpose of giving hair unity, gloss and firmness are generally incompatible with silicone compounds (for example, dimethiconol and nonvolatile dimethylpolysiloxane). Among the silicone compounds, dimethiconol is widely used for the purpose of giving the hair a moist feeling and pointing feeling. However, when it is blended with a vegetable oil containing triglyceride as a main component, both can be blended for the above reasons. The range was limited, and the effect on hair (group, gloss, firmness, moist feeling) was not sufficient.

  Therefore, an object of the present invention is to provide a non-aqueous hair cosmetic that is transparent in appearance, and has excellent elongation and spread, and is smooth, glossy, firm, and moist. It was.

  As a result of intensive studies to solve the above problems, the present inventor has obtained a composition comprising a combination of (A) a vegetable oil mainly composed of triglycerides, (B) dimethiconol, and (C) a cyclic silicone (D). It has been found that the above problems can be solved by containing dicaprylyl ether, and the present invention has been completed.

  In the present invention, by combining (A) a vegetable oil mainly composed of triglycerides, (B) dimethiconol, (C) cyclic silicone, and (D) dicaprylyl ether, the uniformity can be increased and the appearance can be kept transparent. In addition, it is possible to obtain a non-aqueous hair cosmetic that is excellent in spreading and spreading to hair, and is excellent in giving a solid, glossy, firmness, and moist feeling.

  The vegetable oil mainly composed of the triglyceride of component (A) used in the non-aqueous hair cosmetic composition of the present invention includes olive oil, macadamia nut oil, cocoon oil, oil tea oil, avocado oil, almond oil, apricot oil, kiwi fruit seed oil, Kukui nut oil, grape seed oil, coconut oil, sesame oil, wheat oil, wheat germ oil, rice oil, rice germ oil, mountain tea flower oil, safflower oil, sweet almond oil, soybean oil, corn oil, rapeseed oil, pistachio nut oil, castor Oil, sunflower oil, hazelnut oil, safflower oil, evening primrose oil, meadowweed oil, cottonseed oil, peanut oil, rosehip oil, palm oil, coconut oil, and those that are liquid at room temperature are preferred because of their good hair properties. . Furthermore, olive oil, macadamia nut oil, and cocoon oil are preferable, and olive oil is particularly preferable.

  The vegetable oil mainly composed of the triglyceride of the component (A) can be used singly or in combination of two or more, and the blending amount is not particularly limited, but is preferably 0.5 to 15% by weight, preferably 10 to 15% by weight. % Is more preferable. When the content of the vegetable oil containing triglyceride as a main component is less than 0.5% by weight, sufficient gloss and firmness cannot be obtained. When the content is more than 15% by weight, the hair may be glazed or sticky. is there.

  The component (B) dimethiconol used in the non-aqueous hair cosmetic composition of the present invention is a dimethylpolysiloxane having a hydroxyl group bonded to the terminal. In the present invention, this dimethiconol mainly imparts a moist feeling to the hair. It contributes to doing.

  The blending amount of component (B) dimethiconol is not particularly limited, but is preferably 0.9 to 7.5% by weight, and more preferably 3 to 6% by weight. When the content of dimethiconol is less than 0.9% by weight, the hair cannot be sufficiently moistened, and when it is more than 7.5% by weight, the hair may be sticky.

  Examples of commercially available products of dimethiconol include “X-21-5666” (manufactured by Shin-Etsu Chemical), “X-21-5613” (manufactured by Shin-Etsu Chemical), “1501 Fluid” (manufactured by Toray Dow Corning). "1503 Fluid" (manufactured by Dow Corning Toray).

  Various cyclic silicones can be used as the component (C) used in the non-aqueous hair cosmetic composition of the present invention, and decamethylcyclopentasiloxane, octamethylcyclotetrasiloxane, and dodecamethylcyclohexasiloxane are particularly preferable. In the present invention, the cyclic silicone mainly has an action of reducing stickiness to fingers during application by volatilizing itself.

  The cyclic silicone of component (C) can be used singly or in combination of two or more, and the blending amount is not particularly limited, but is preferably 50% by weight or more, more preferably 60 to 85% by weight. Within this range, stickiness can be suppressed and the intended effect can be sufficiently obtained.

  The component (D) dicaprylyl ether used in the non-aqueous hair cosmetic composition of the present invention contributes to dissolving the components (A), (B), and (C) transparently in appearance, and is excellent in itself. Since it is an oil agent with a very light usability with spreadability, it spreads well on the hair and can be applied uniformly.

  Although the compounding quantity of the dicaprylyl ether of the component (D) in the non-aqueous hair cosmetic composition of the present invention is not particularly limited, it is preferably 5 to 25% by weight, particularly preferably 5 to 15% by weight. When the content of dicaprylyl ether is less than 5% by weight, transparency and elongation spread may be deteriorated. When the content is more than 25% by weight, the effect is not improved and it is not economical.

  Examples of commercially available dicaprylyl ether include “COSMACOL OE” (manufactured by SASOL).

  The present invention relates to a non-aqueous hair cosmetic, but the non-aqueous means that water is not blended in the formulation design, and is not required to be completely non-aqueous, and substantially Any non-aqueous system may be used.
