Disclosure of Invention

Problems to be solved by the invention

As a conventional oily hair cosmetic, it is known that a high hair-gathering property is imparted to hair by blending a vegetable oil, and a glossy finish feeling is obtained. Further, it is also known that a light finish feeling is obtained by adding silicone having a high polymerization degree to hair to impart a good touch feeling (dry feeling) with a dry finger-passing property to hair.

Oily hair cosmetics that achieve high lift are generally sticky and have a heavy finish. On the other hand, an oily hair cosmetic giving a dry feeling is generally poor in manageability. Therefore, high closeness and a dry feeling are characteristics of the reflection of the two rhythms, and a problem that both of these characteristics can be satisfied is not known.

In addition, silicones having a high degree of polymerization have particularly poor compatibility with vegetable oils, and an oily hair cosmetic in which they are used in combination has not been obtained so far.

In view of the above, an object of the present invention is to provide an oil-based hair cosmetic that can impart a dry feel, a gathering property, and a luster to hair.

Means for solving the problems

The present invention has been completed based on these technical ideas.

Specifically disclosed is an oil-based hair cosmetic composition containing 0.3-5.0% by mass of component (A), 7.0-50.0% by mass of component (B) and 5.0-50.0% by mass of component (C).

Component (A): a silicone compound having a viscosity of 1000 to 3000 mPas at 25 DEG C

Component (B): vegetable oil and/or fatty acid triglyceride

The content of water in the oil-based hair cosmetic composition of the present invention is not particularly limited, and is preferably 3.0 mass% or less, more preferably 1.5 mass% or less, based on 100 mass% of the oil-based hair cosmetic composition of the present invention.

The oil-based hair cosmetic of the present invention is not particularly limited, and can be produced by a known or conventional method. For example, the above-mentioned components may be mixed and stirred by a homomixer, impeller mixer or the like.

The oily hair cosmetic of the present invention is a so-called hair oil. Examples of the oily hair cosmetic of the present invention include leave-on conditioners, hair conditioners, and the like. The oil-based hair cosmetic of the present invention is used for the following purposes, for example: the object of hair dressing by suppressing the spread of hair; the purpose of providing shine to the hair; the purpose of providing a dry feel to the hair; the purpose of improving the finger-passing ability of hair; the purpose of protecting hair from the heat of a hair dryer or hair iron or the like.

The method of using the oil-based hair cosmetic of the present invention is not particularly limited, and examples thereof include the following methods. (i) After shampooing and drying with a towel, an appropriate amount of the oily hair cosmetic of the present invention is applied to the hair in whole or in part, and dried with a hair dryer or the like. (ii) The oily hair cosmetic of the present invention is applied to the whole or part of dry hair or slightly wet hair in a suitable amount, and the hair is styled using a hair iron or the like as necessary. The oily hair cosmetic of the present invention may be used in combination with other hair styling agents to perform hair styling.

The oil-based hair cosmetic composition of the present invention comprises, as oil components, a silicone compound having a viscosity of 1000 to 3000 ten thousand mPa · s at 25 ℃ (component (a)) and a vegetable oil and/or fatty acid triglyceride (component (B)) in specific proportions. Generally, the compatibility between the component (a) and the component (B) is poor, and it is difficult to sufficiently exert their respective functions only by mixing them. In contrast, in the present invention, by blending octyl methicone [ component (C) ] in a specific ratio, the compatibility between component (a) and component (B) is drastically improved. Thus, the oil-based hair cosmetic composition of the present invention can exert both the effect of component (a) in imparting a dry feel to hair and the effect of component (B) in imparting a hair-gathering property to hair, and it is presumed that by further compounding component (C), the refractive index of the hair cosmetic composition is increased, but sufficient luster can be imparted to hair.

(evaluation)

Each of the hair cosmetics obtained in examples and comparative examples was evaluated as follows. The evaluation results are set forth in the table. The samples with poor formulation stability were not evaluated. Evaluation was performed by 3 professional judges.

(1) Dry and comfortable feeling

After bleaching the hair strands (strands of 30cm in length, 10g in weight, with intact cuticle) with hydrogen peroxide and ammonia, the hair strands were washed with shampoo, coated with conditioner and rinsed. Further, the sample hair was dried with a hair dryer to prepare a sample hair bundle ("sample hair bundle before coating").

About 0.3g of each of the hair cosmetics obtained in examples and comparative examples was uniformly applied to the sample hair bundle before application, and dried for 3 minutes by a hair dryer to prepare a hair bundle coated with the hair cosmetic ("sample hair bundle after application").

The sample hair tresses before coating and the sample hair tresses after coating are respectively passed through the finger from the upper part to the lower part of the hair tresses, whether the finger is hooked or not is confirmed, and the dryness feeling is judged according to the following standard through the comparison of the above-mentioned touch feeling of the sample hair tresses before coating and the sample hair tresses after coating.

[ judgment standards ]

O (good): the touch feeling of the finger being caught was remarkably reduced and the finger passing property was good as compared with the sample hair strand before application.

X (bad): the finger was caught to the same touch as the sample tress before coating, or felt stronger than the sample tress before coating.

(2) Hair gathering and luster

After the evaluation in (1) above, the applied sample hair bundle was visually observed, and the hair gathering property and luster were determined according to the following criteria.

[ criterion for determining hair-gathering Property ]

O (good): the hair bundle is not spread downward, the hair bundle is gathered as a whole, and further the front end portion of the hair bundle is also gathered.

Δ (available): the hair bundle is not spread downward, and the hair bundle is gathered as a whole, but the front end portion of the hair bundle is not gathered slightly.

X (bad): the hair bundle is obviously spread downwards as a whole.

[ determination criterion of gloss ]

O (good): when the hair is irradiated with light, the hair has a luster reflecting a dazzling light.

X (bad): there is no gloss, or even if there is gloss, there is no glare reflected when the hair is illuminated.

(3) Formulation stability

The properties of each of the hair cosmetics obtained in examples and comparative examples (after 3 days from the preparation) were visually observed and evaluated according to the following criteria.

[ criterion for determining stability of preparation ]

O (good): without separation, was homogeneous.

X (bad): separation, non-uniformity was observed

The oily hair cosmetic of the present invention (examples) was evaluated to be excellent in formulation stability and excellent in dry feel, spreadability and gloss. On the other hand, the feeling of dryness was poor when the component (A) was not blended (comparative example 1) and when a silicone compound having a viscosity of less than 1000 ten thousand mPas at 25 ℃ was blended in place of the component (A) (comparative example 2). In addition, when the amount of component (a) is large (comparative example 3), the stability of the preparation is poor. The gathering properties were poor in the case where the component (B) was not compounded (comparative example 4) and in the case where the component (B) was not compounded and the amount of isononyl isononanoate was increased (comparative example 5). In comparative example 5, the hair was poor in dryness, and the coated sample hair was rough and had poor touch. When the component (A) and the component (C) were not compounded (comparative example 6), the dry touch and gloss were poor. When the component (C) was not blended (comparative example 7), the preparation stability was poor.

Further, formulation examples of the oil-based hair cosmetic of the present invention are shown below.
