Description

  The present invention relates to a hair treatment composition that can be prepared in a short time of use (during use). In particular, the present invention is a highly safe hair treatment composition that does not cause irritation to hair and skin that can be prepared within a short time by the user.

  There are two types of hair treatment compositions: hair cream type and hair oil. Hair cream does not run out of the hand (compared to hair oil) and is an emulsified type. Compared without sticking to the hand when applied to hair. It has a refreshing feel and has a conditioning effect on the hair due to oil.

By the way, a hair cream type hair treatment composition needs to maintain a stable emulsion. In order to obtain a stable emulsion, a high-pressure homogenizer is used to refine the emulsion or to add a thickener. However, the high-pressure homogenizer is an expensive mechanical facility, and a sufficiently satisfactory thickener has not yet been found. In order to maintain the emulsion stability, a relatively large amount of surfactant may be blended. However, the surfactant has safety problems such as the occurrence of irritation to the skin, and is applied to the hair. When washing the hair later, the surfactant dissolves and flows out in the washing water, and this surfactant causes a problem of global environmental pollution. Therefore, there is a tendency to reduce the amount of the surfactant used to solve these problems.

Patent Document 1 discloses a cosmetic preparation prepared at the time of use, which is stable in diameter and does not impair the effectiveness of ingredients. According to this patent document 1, it is a cosmetic preparation at the time of use which has an aqueous phase which is liquid at 10 to 30 ° C. and an oil phase which is liquid at 10 to 30 ° C., and this cosmetic is powdered at 10 to 30 ° C. It describes that it may have a body phase. The powder phase component may be any component that is usually blended and used in cosmetics, and it is described that it may or may not dissolve in the water phase or oil phase when preparing the cosmetics during use. Yes. In addition, amino acids such as proline and dipotassium glycyrrhizinate as components that are soluble in the aqueous phase, stearyl glycyrrhetinate as a component that is soluble in the oil phase, and inorganic pigments as powders that are insoluble in both the aqueous phase and the oil phase are shown. In this cosmetic, the water phase, the powder phase, and the oil layer are housed in separate containers, and these are prepared into an emulsion at the time of use. Therefore, storage stability as an emulsion is a problem. There is no. However, it is also described that it is preferable to add a surfactant to the cosmetics prepared at the time of use in order to stabilize the cosmetics after the preparation at the time of use. Therefore, although the technique described in Patent Document 1 has been considered to reduce the amount of the surfactant used, it can be said that the stability over time is obtained by using the surfactant. It is difficult to say that the problems caused by the use of the above-described surfactants have been completely solved.

  The present inventor does not need to use expensive mechanical equipment such as a high-pressure homogenizer, and results of various studies in order to obtain a hair treatment composition (cream state product) that does not cause problems due to the use of a surfactant as much as possible. The present invention has been completed, and the object of the present invention is to enable a user to quickly and easily (does not require special skills) at the time of use in a general household, for example, in a creamy or gel state in units of several tens of seconds. It is to provide a hair treatment composition (cream product) that can be prepared.

  The gist of the present invention is a hair treatment composition prepared at the time of use consisting of a liquid aqueous phase and a powder phase or a granular phase (hereinafter sometimes referred to as a first group composition), or a liquid aqueous phase, A hair treatment composition prepared at the time of use comprising a powder phase or a granule phase and a liquid oil phase, wherein the powder phase or the granule phase contains a water-soluble polymer. It is a thing. The hair treatment composition may further contain an inorganic powder phase together with a water-soluble polymer, and the powder phase or granule phase is converted into liquid animal oil, vegetable oil, mineral oil, synthetic oil, You may process with waxes, glycerol, silicone oil, etc.

  Since the present invention is prepared at the time of use as described above, since the user makes the necessary amount immediately before, the storage stability of the emulsion is unnecessary, and even if a surfactant is used, the amount may be extremely small. Can prepare with confidence. In addition, there is an advantage that the oil phase and the water phase can be selected according to the user's preference, and there is an effect that the damaged hair can be recovered by the oil phase component satisfying the feeling of use suitable for the personal desire.

The present invention will be described in detail. The water phase used in the present invention is characterized in that tap water from ordinary households can be used directly. In addition, water-soluble colorants, flavors, soy peptides, dry milk, sugars, sorbitol, annitol, etc.], polyhydric alcohols [glycerin, propylene glycol, 1,3-butylene glycol, polyethylene glycol, 3- One's special product can be easily achieved by using a liquid in which one or more appropriate amounts of methyl-1,3-butanediol etc.] have been added to tap water in advance.

  The powder phase or granule phase, which is a first group composition that can be used in the present invention, has a thickening effect to form a cream body in hair treatment, and possesses the ability to uniformly apply to hair, Amplify the treatment effect. Specifically, sodium carboxymethylcellulose, gum arabic, xanthan gum, guar gum, cationized guar gum, sodium polyacrylate, hydroxyethyl cellulose, methyl erulose, carboxyvinyl polymer, ethyl trimethylammonium methacrylate polymer, O- [2- chloride] Water-soluble polymers such as hydroxy-3- (trimethylammonio) propyl] hydroxyethylcellulose, vinylpyrrolidone / N, N-dimethylaminoethylmethacrylic acid copolymer diethyl sulfate solution are used. One or more of these may be used in appropriate combination.

  The water-soluble polymer can be mixed with an inorganic powder phase depending on the purpose. The inorganic powder phase is prepared at the time of use. In order to easily obtain a cream body in a uniform state, the water-soluble polymer is in contact with the aqueous phase and the water-soluble polymer swells and dissolves. It has an important effect, and it is possible to rapidly increase the viscosity of a uniform system by using hand stirring or a spoon or the like at home without using a quick stirring device. That is, when the water-soluble polymer particles absorb the aqueous phase liquid and become a paste state, it becomes difficult for the aqueous phase liquid to penetrate into the aggregated water-soluble polymer particles in a short time. A large amount of “Mamako” is generated and a uniform cream body cannot be obtained, and the purpose of preparation at the time of use cannot be achieved. The inorganic powder phase prevents this phenomenon and is effective for washing hair with water (including normal hot water) after the hair treatment has been applied to the hair and left for an appropriate time (several minutes). Thus, a sense of use that is sensuously smooth is obtained. Specific examples of inorganic powder phases include talc, inorganic silicic acids, mica, natural clay minerals [kaolin, bentonite, halosite] modified natural clay minerals (containing water-soluble polymer), synthetic clay minerals , Calcium carbonate, titanium oxide, muscovite, etc. can be used alone or in combination of two or more.

  The use ratio of the water-soluble polymer phase and the inorganic powder phase in the first group composition is preferably in the range of 2-8: 10-0 by weight.

The powder phase or granule phase which is the first group composition preferably modifies the surface of these powders (the wettability of the powder surface with the aqueous phase and the scattering prevention effect when handling the powder). A liquid oil phase component suitable for the above can be coated on the surface of the water-soluble polymer phase or the inorganic powder phase used as necessary. The powder surface modifier may be the same as the liquid oil phase component.
In other words, by modifying the powder surface, it is possible to omit part or all of the conventional additive components (for example, surfactants, higher alcohols, etc.), which is excellent in terms of safety and the global environment. A hair treatment prepared at the time of use can be obtained.

  The liquid oil phase of the present invention is not particularly limited as long as it is an oily component usually blended in cosmetics. This oil phase component may be used alone or in combination of two or more. Specifically, vegetable oils (olive oil, sunflower oil, sesame oil, jojoba oil, soybean oil, avocado oil, apricot oil, safflower oil, grape seed oil, kukuikotsu oil, macadamian nut oil, peanut oil, etc.) and silicone oil [methylpoly Siloxane, methylphenylpolysiloxane, octamethycyclotetrasiloxane, decamethylcyclopentasiloxane, polyoxyethyl / methylpolysiloxane copolymer, poly (oxyethylene / oxypropylene) methylpolysiloxane copolymer, etc.] hydrocarbon [flow Paraffin, light fluid isoparaffin, squalane, etc.], fatty acid ester [isopropyl myristate, octyldodecyl myristate, isopropyl palmitate, 2-ethylhexyl palmitate, isopropyl isostearate, isostearate Isocetyl, octyldodecyl isostearate, cetyl 2-ethylhexanoate, cetostearyl 2-ethylhexanoate, propylene glycol dicaprylate, propylene glycol di (capryl / capric acid), neopentyl glycol dicaprate, glyceryl tricaprylate, tri-2- Ethylhexanoic acid pentaerythritol, pentaisoerythritol tetraisostearate, diisostearyl malate, di-2-ethylhexyl succinate, diethoxyethyl succinate, diisopropyl adipate, diisobutyl adipate, etc.].

  In the present invention, as described above, it is possible to easily obtain a good cream body to achieve the object without necessarily adding a surfactant, a higher alcohol or the like to the composition. A composition to which a slight amount of an anionic surfactant or a cationic surfactant is added is not limited as a hair treatment composition prepared at the time of use. For example, nonionic surfactants specifically include sorbitan fatty acid esters [sorbitan monolaurate, sorbitan monooleate, sorbitan monoisostearate, etc.], polyoxyethylene (POE) alkyl ethers [POE lauryl ether, POE cetyldecyl ether, POE stearyl ether, POE isostearyl ether, POE octyldodecyl ether, POE behenyl ether, etc.], POE sorbitol tetra fatty acid ester [POE castor oil tetraoleic acid POE sorbite etc.], POE sorbitan fatty acid ester [monolauric acid POE (especially 20EO (20 Moleethylene oxide addition)) sorbitan, monooleic acid POE (especially 20EO) sorbitan, etc.], POE hydrogenated castor oil, etc. may be used.
