Description

  The present invention relates to a hair conditioning composition, and more specifically, a cationic surfactant, a nonionic surfactant, a higher alcohol, a polyhydric alcohol having three or more hydroxyl groups in a molecule, an oily component, and water components. It is an emulsified composition manufactured using a combination two-step emulsification method, and it is easy to apply evenly because it is familiar with the hair at the time of application, and it is smooth, soft and moisturized when finished after drying. The present invention relates to a hair conditioning composition having an excellent conditioning effect that gives a touch and maintains the smoothness and smoothness of fingers after a lapse of time.

  Hair conditioning compositions that give hair a conditioning effect have various forms such as liquid, emulsion, cream, mist, foam (foam), etc. in terms of dosage form, hair rinse, hair treatment, hair cream, hair Non-aerosol products such as packs and hair essences, as well as aerosol products such as hair conditioning foams and hair conditioning sprays, for in-bath products (type to wash away) and out-bath products (type to leave hair on) Widely used.

  Usually, a hair conditioning composition such as a hair rinse is prepared by combining a cationic surfactant, a higher alcohol and water to form a gel having a liquid crystal structure, and adding an oily component thereto to emulsify. In addition, a thin oil-based protective film can be formed on the hair surface after application to impart smoothness and the like. The production method is generally a dispersion emulsification method in which a higher alcohol and an oily component are added to a cationic surfactant aqueous solution and emulsified (for example, see Non-Patent Document 1).

However, the conventional hair conditioning composition is not sufficiently familiar with the hair surface, and it may be difficult to uniformly apply to the hair. In addition, although the hair is smooth and soft when finished immediately after drying, the hair tends to become harder as time passes.For example, even if hair conditioning is performed the night before, the effect is lost the next day. As a result, the conditioning effect may not be sustained. Therefore, it is hoped to develop a hair conditioning composition that is easy to apply evenly to the hair and that has a long-lasting conditioning effect, so that if the hair conditioning is performed the night before the day, sufficient conditioning effects remain even after one day. For that reason, for example, blending of specific compounds having effects peculiar to hair such as room temperature liquid higher alcohol and highly polymerized polyethylene glycol has been studied (for example, see Patent Document 1 and Patent Document 2).

  In the present invention, the nonionic surfactant of component (B) is preferably one having an HLB in the range of 6 to 14 in order to obtain sufficient emulsifying power in two-stage emulsification and good stability of the emulsified composition. This HLB range is, for example, in the case where a high HLB nonionic surfactant outside this range is combined with a low HLB nonionic surfactant, the weighted average value is in the range of 6-14. If it is, it means that it is applicable.

  In this invention, the nonionic surfactant of a component (B) can be used individually by 1 type or in combination of 2 or more types as needed, The compounding quantity is 0.1-5 in all compositions. %, More preferably 0.3 to 3%. Within this range, the emulsified state of the composition is also good, and since it is easy to adjust to the hair, it can be uniformly applied to the hair surface and has sufficient stability over time. If it is less than 0.1%, sufficient emulsification is difficult to achieve, so that it may be difficult to apply evenly to the hair due to insufficient conformity to the hair. Also, sufficient stability over time is difficult to obtain. Even if it exceeds 5%, the emulsified state and the stability over time cannot be further improved, and the hair tends to be sticky.

  The higher alcohol of component (C) used in the present invention forms a gel having a liquid crystal structure in the presence of water of component (F) when used in combination with the cationic surfactant of component (A) as a conditioning aid. Because of its moderate viscosity, it is easy to handle when picked up and gives good usability. In addition, the stability of the system over time is improved.

If it is less than 0.2%, gel formation is not sufficient, and sufficient stability over time may not be obtained. Moreover, when it mixes exceeding 10%, the viscosity of a composition will become high with time and the hair after use may also become hard with time.

  Component (D) used in the present invention is a polyhydric alcohol having 3 or more hydroxyl groups in one molecule, and this component (D) prepares an oil-in-polyhydric emulsion in the middle of the two-stage emulsification process. This is an essential component. Component (D) also has a wetting action on the hair, and in the present invention, it also has a function of imparting a softness and moist feeling to the hair immediately after drying. In the present invention, the polyhydric alcohol of component (D) can be used without any particular limitation as long as it has 3 or more hydroxyl groups per molecule. Specific examples include glycerin, diglycerin, polyglycerin and the like, and glycerin and diglycerin are particularly preferable from the viewpoint of ease of two-stage emulsification, softness to hair, and moist feeling.

  In this invention, the polyhydric alcohol of a component (D) can be used individually by 1 type or in combination of 2 or more type as needed, The compounding quantity is 5 to 50% in the whole composition, More preferably, it is 10 ~ 30%. Within this range, a good gel can be formed during the two-stage emulsification process, and softness and moist feeling can be sufficiently imparted to the hair immediately after drying.

  The oil component of the component (E) used in the present invention is blended for the purpose of giving the hair gloss, smooth feel, and good combing properties, and further obtaining the durability of these effects. In the present invention, the oily component of component (E) is an oily component that is added to the mixture of components (A) to (D) in the first stage of two-stage emulsification to form an oil-in-polyhydric emulsion. . The oil component of the component (E) is not particularly limited as long as it is an oil component that is usually used in cosmetics, etc., origin of animal oil, vegetable oil, synthetic oil, solid oil, semi-solid oil, liquid oil, volatilization Regardless of the nature of the oil. As the component (E), for example, hydrocarbons, fats and oils, waxes, hardened oils, ester oils, fatty acids, organic silicones, fluorinated oils, lanolin derivatives and the like can be used, and more specifically Hydrocarbons such as liquid paraffin, light liquid isoparaffin, squalane, vegetable squalane, petrolatum, polyisobutylene, polybutene, paraffin wax, ceresin wax, microcrystalline wax, polyethylene wax, ethylene propylene copolymer, montan wax, fish trops wax, etc. Oils such as beeswax, olive oil, castor oil, mink oil, macadamia nut oil, camelia oil, rose pip oil, avocado oil, waxes such as beeswax, carnauba wax, candelilla wax, gay wax, jojoba oil, 2-ethyl Cetyl xanoate, isononyl isononanoate, isopropyl myristate, isopropyl palmitate, octyldodecyl myristate, glyceryl tri-2-ethylhexanoate, polyglyceryl diisostearate, diglyceryl triisostearate, glyceryl tribehenate, hexa (hydroxystearic acid / Stearic acid / rosinic acid) dipentaerythrityl, diisostearyl malate, neopentyl glycol dioctanoate, cholesteryl isostearate, cholesteryl hydroxystearate, cholesteryl stearate, lanolin fatty acid cholesteryl, olein fatty acid phytosteryl, N-lauroyl-L-glutamic acid di ( Cholesteryl behenyl octyldodecyl), N-lauroyl-L-glutamate di (phyto) Esters such as teryl 2-octyldodecyl), fatty acids such as stearic acid, lauric acid, myristic acid, behenic acid, isostearic acid, oleic acid, low polymerization dimethylpolysiloxane, high polymerization dimethylpolysiloxane, methylphenyl Organic silicones such as polysiloxane, decamethylcyclopentasiloxane, octamethylcyclotetrasiloxane, cross-linked organopolysiloxane, amino-modified organopolysiloxane, fluorine-modified organopolysiloxane, perfluorodecane, perfluorooctane, perfluoropolyether Fluorine oils such as lanolin, lanolin derivatives such as lanolin, lanolin acetate, lanolin fatty acid isopropyl, and lanolin alcohol.

Within this range, the hair can be given a sufficient gloss, smooth feel, and combing quality, and these effects can be sustained. If it is less than 0.1, it is difficult to sufficiently obtain the above effect, and even if it exceeds 20%, it is difficult to obtain further improvement of the effect, which tends to give the hair a sticky or heavy feel. .

  The water of component (F) used in the present invention is not particularly limited as long as it is water that can be usually used for cosmetics and the like. For example, purified water, distilled water, hot spring water, deep ocean water, lavender flower water, and the like. As necessary, one kind of these can be used alone or two or more kinds can be used in combination.

  The hair conditioning composition of the present invention comprises a first step of preparing a polyhydric alcohol-in-oil emulsion by adding the component (E) to the mixture of the above components (A) to (D), and then the polyhydric alcohol-in-oil type. It is produced by a two-stage emulsification method comprising a second stage by adding the component (F) to the emulsion to obtain an oil-in-water emulsion. In a normal dispersion emulsification method in which an aqueous phase is used as an outer phase and an oily phase is added to emulsify it, it is not easy to uniformly form a liquid crystal structure with a cationic surfactant, a higher alcohol and water, and it is partially higher. The precipitation of alcohol may make it difficult to uniformly apply to the hair, or the hair finish immediately after drying may become hard. On the other hand, in this invention, it finally manufactures by making the cationic surfactant of a component (A) coexist with a component (B)-(D) in the 1st step of the said two-stage emulsification. A uniform liquid crystal structure can be formed in an oil-in-water emulsion. Therefore, the hair conditioning composition prepared by this two-stage emulsification process is easy to apply evenly to the hair surface and is more easily adapted to the hair. Moreover, since it is uniformly applied to the hair surface, it is difficult for the coating film to peel off due to friction or the like, and the smoothness of the hair and the goodness of the finger can be maintained even after a long time.

  That is, even if the hair conditioning composition has the same composition, for example, the one produced by the two-stage emulsification method of the present invention can be completely different in quality compared to the one produced by the usual dispersion emulsification method. . In addition, the two-stage emulsification method tends to lower the viscosity of the composition due to the formation of its uniform liquid crystal structure, which also facilitates uniform application to the hair surface and makes it more familiar to the hair. Contributes to better. In the first stage of the two-stage emulsification method, a polyhydric alcohol other than component (D) may be added as an optional component to the mixture of components (A) to (D). However, the amount added is preferably 50% or less in the total polyhydric alcohol so as not to impair the effects of the present invention.

  In the hair conditioning composition of this invention, it is preferable that the compounding mass ratio (B) / (A) of a component (A) and a component (B) exists in the range of 1/10-1/1. Within this range, a gel with a more uniform liquid crystal structure can be formed, and the more remarkable effects of the present invention can be obtained.

  In addition to the essential components described above, the hair conditioning composition of the present invention includes ethyl alcohol and isopropyl, which are usually blended in cosmetics for hair, in a quantitative and qualitative range depending on the purpose.

  The hair conditioning composition of the present invention can be implemented in various forms such as liquid, emulsion, cream, mist, foam, etc., depending on the combination with other components and the mechanism of the container. It can be carried out as a treatment, hair cream, hair pack, hair essence or the like. In addition, in a quantitative and qualitative range that does not impair the effects of the present invention, various propellants such as liquefied petroleum gas, nitrogen gas, carbon dioxide gas, dimethyl ether or a mixture thereof are added and filled into an aerosol container to obtain a hair foam, hair It can also be implemented as an aerosol product such as a spray foam. The hair conditioning composition of the present invention exhibits good effects in both in-bath products and out-bath products and can be implemented.
