Description

The present invention relates to a hair cosmetic that does not contain a silicone compound and does not wash away. More specifically, the present invention relates to a method that suppresses the crispness and stiffness of the hair and gives the hair good fingering, cohesion and gloss. The present invention relates to a non-washable hair cosmetic.

Conventionally, hair cosmetics such as hair shampoos, hair treatments, hair styling agents, etc. have a feeling of moistness, smoothness, good touch, smoothness, good hand feeling, feeling of unity, etc. after use. It is demanded that an excellent texture and good gloss can be imparted, and various components are added to the hair cosmetic in order to exhibit such effects. Among them, silicones suppress the feeling of touch, crispness and stiffness, especially in hair cosmetics intended for hair treatments, and protect the hair from physical and chemical irritation, resulting in the generation of split ends and cut hairs. It is widely used for the purpose of suppressing.

However, when silicones are used repeatedly on the hair, they cause so-called accumulation on the hair surface (build-up), give an unpleasant feel such as a feeling of stiffness, a squeaky feeling, and when a hair dye or a permanent wave agent is applied. There was a drawback that it had an adverse effect of lowering the dyeability and lowering the waveability.

Therefore, in hair cosmetics, proposals have been made that non-silicone compounds such as specific carbonates and esters of specific monohydric alcohols and monohydric carboxylic acids solve the above problems. (See Patent Documents 1 to 3). Further, cosmetics having a silicone-like feel containing oligomeric esters containing dimer acid and dimer diol as structural units (see Patent Document 4), and silicone-like containing neopentanoic acid and branched alcohol esters of hydrocarbons 10-13. Although a touch-imparting agent has been proposed (see Patent Document 5), it is not satisfactory with respect to the effect of suppressing the crispness and stiffness of the hair, and giving good touchability, cohesion and gloss to the hair. It was.

JP 2000-512284 A JP 2000-512285 A Special table 2001-526106 gazette Japanese Patent Laid-Open No. 2004-262783 JP 2005-154286 A

In view of the above circumstances, the present invention is a type of hair that does not wash away and does not contain a silicone compound, which can suppress the feeling of roughness and firmness of the hair and can give the hair good fingering, cohesion and gloss. The purpose is to provide cosmetics.

As a result of intensive studies to achieve the above object, the present inventor has obtained a specific ratio of ester oil that is liquid at room temperature and has a viscosity of 3 to 100 mPa · s at 20 ° C. and vegetable oil that is liquid at room temperature. It was found that the above-mentioned problems of hair cosmetics can be solved by combining the above.

That is, the hair cosmetics of the present invention that do not wash away
(A) at least one ester oil that is liquid at normal temperature and has a viscosity of 3 to 100 mPa · s at 20 ° C. (B) contains at least one vegetable oil that is liquid at normal temperature, component (A): component The blending ratio (mass ratio) of (B) is 10: 0.1 to 1: 3 and does not contain a silicone compound.

The non-washing-type hair cosmetic of the present invention is further selected from hydrocarbons, higher alcohols, fatty acids, surfactants, thickeners, plant extracts, humectants, pigments, bactericides, and fragrances. It is preferable to contain 1 type, or 2 or more types.

Furthermore, the component (A) is preferably at least one selected from octyl palmitate and isostearyl neopentanoate.

According to the non-washing-out type hair cosmetic of the present invention, it is possible to suppress the feeling of firmness and firmness of the hair, and to impart good fingering, unity and gloss to the hair.

Hereinafter, the non-washing-type hair cosmetic of the present invention will be described in detail.

The ester oil which is the component (A) of the present invention is liquid at normal temperature and has a viscosity of 3 to 100 mPa · s at 20 ° C. The normal temperature in this invention means 15-25 degreeC according to the general rule of the Japanese Pharmacopoeia. Examples of the ester oil include the following, and commercially available products can be used. For example, cetyl ethylhexanoate (Nisshin Oilio Group Co., Ltd. Saracos 816T), isonondecyl isononanoate (Saracos 913, etc.), isononyl isononanoate (Saracos 99, etc.), octyl palmitate (Saracos P-8) , Crodamol OP manufactured by Croda Japan Co., Cerafil 368 manufactured by ISP Japan Co., Ltd.), Isostearyl myristate (Cosmol 812 manufactured by Nisshin Oillio Group Co., Ltd.), Neopentyl glycol diethylhexanoate (Cosmol 525, etc.) ), Neopentyl glycol dicaprate (such as Estolemol N-01), myristyl isooctanoate (such as Crodamol MIO manufactured by Croda Japan Co., Ltd.), di-2-ethylhexyl succinate (such as Kurodamol OSU), neopentanoic acid Sosuteariru [ISP Japan Co., Ltd. ceramic filters 375, etc.] and the like. Among these, octyl palmitate and isostearyl neopentanoate can be preferably used.

In the present invention, one or more of these ester oils are appropriately selected and used. The blending amount is preferably 25 to 99% by mass in the oily component of the hair cosmetic. When the proportion of the ester oil is less than 25%, there may be no improvement in the feeling of crispness and stiffness on the hair.

Examples of the vegetable oil that is liquid at room temperature as the component (B) of the present invention include, for example, avocado oil, almond oil, apricot oil, olive oil, olive squalane, kiwifruit 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, coconut oil, corn oil, rapeseed oil, pistachio oil, castor oil, sunflower oil, hazelnut oil, safflower oil Jojoba oil, macadamia nut oil, meadow home oil, cottonseed oil, peanut oil, rosehip oil and the like.

In the present invention, one or more of these vegetable oils are appropriately selected and used. The blending amount is preferably such that the proportion of the hair cosmetic in the oily component is 0.99 to 75% by mass. When the blending of the vegetable oil is 75% or more, there is a case where improvement of fingering property to the hair is not observed.

The content ratio of the component oil (A), which is liquid at normal temperature and has a viscosity of 3 to 100 mPa · s at 20 ° C., and the component oil (B), which is liquid at room temperature, is the feel at the time of application and the crispness of the hair. It is a mass ratio of 10: 0.1 to 1: 3 from the suppression of the feeling of stickiness and glossiness. When the blending ratio of the vegetable oil is more than 3, the oily smell becomes strong with respect to the hair composition, and the finger-penetrating property of the hair may not be improved. On the other hand, if the blending ratio is less than 0.1, it may not be possible to give a preferable gloss to the hair and the unity may not be improved.

In the non-washing-type hair cosmetic of the present invention, other additional components that are usually used in hair cosmetics can be blended as necessary within the range not impairing the effects of the present invention. As these additional components, for example, hydrocarbons, higher alcohols, fatty acids, surfactants, thickeners, plant extracts, humectants, pigments, bactericides, fragrances, etc. can be blended, Examples of hydrocarbons include α-olefin oligomers, light isoparaffins, light liquid isoparaffins, synthetic squalanes, vegetable squalanes, squalanes, polybutenes, liquid isoparaffins, liquid paraffins, etc .; examples of higher alcohols include , Isostearyl alcohol, 2-octyldodecanol, decyltetradecanol, oleyl alcohol, 2-hexyldecanol, linoleyl alcohol, linolenyl alcohol and the like; Examples of fatty acids include isostearic acid and oleic acid , Linoleic acid, etc. The surfactant may be, for example, any of a nonionic surfactant, a cationic surfactant, an amphoteric surfactant, and an anionic surfactant. Examples of the nonionic surfactant include: Polyoxyethylene alkyl ethers such as polyoxyethylene cetyl ether, sorbitan monolaurate, polyoxyethylene sorbitan monostearate, glyceryl monooleate and other polyoxyethylene hydrogenated castor oil can be exemplified as a cationic surfactant. Examples include cetyltrimethylammonium chloride, distearyldimethylammonium chloride, stearyldimethylbenzylammonium chloride, stearyltrimethylammonium chloride, and amphoteric surfactants such as lauryldimethylaminoacetic acid betaine N, N-dimethyl-N-alkyl-N-carboxymethylammonium betaine, 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, and the like can be exemplified as an anionic surfactant. Examples include sodium polyoxyethylene lauryl ether sulfate and triethanolamine lauryl sulfate; examples of thickeners include vinyl polymer compounds and acrylic polymer compounds, and vinyl A pyrrolidone-hexadecene copolymer can be exemplified.

Such additional ingredients are generally used individually at a concentration of about 0.01 to 10% by weight, preferably about 0.05 to 5% by weight of the hair cosmetic.
