Description

  The present invention relates to a hair cleansing composition, and more particularly, hair cleaning such as a hair shampoo that imparts a sufficiently moist and coherent feeling to the hair without impairing foaming properties, and also suppresses a squeaky feeling during rinsing. It is related with an agent composition.

In hair cleaning compositions such as hair shampoos, rich foaming is one of the important quality characteristics. However, when a large amount of a surfactant is added to improve the foaming property, there is a problem that the hair is excessively degreased due to its high detergency and the hair becomes dry after drying. As one of the methods for improving this, Patent Document 1 discloses oil components such as hydrocarbon oils such as squalane, ester oils such as isopropyl myristate and jojoba oil, and higher alcohols such as oleyl alcohol. In addition, Patent Documents 2 to 3 propose a method of blending a high polymerization degree silicone oil. However, although these methods can improve excessive degreasing by the oil component added, they reduce foaming, which is an important characteristic as a hair cleansing composition, and cause squeaky feeling during rinsing. There was a problem during use. Moreover, it was not fully satisfactory also in the effect which the consumer desires the moist feeling after hair washing, and the feeling of unity. From this, it is hoped to develop a hair cleanser composition that has a good feeling of moistness and cohesion after drying as well as foaming at the time of shampooing, and a feeling of use during washing such as a squeaky feeling during rinsing. It was rare.

  It is a hair cleansing composition that imparts a sufficiently moist and coherent feeling to the hair without impairing foaming properties, and also suppresses the squeaky feeling during rinsing.

  Hereinafter, the present invention will be described in detail.

  Examples of the anionic surfactant used in the present invention include alkyl sulfates and alkyl ether sulfates having 8 to 18 carbon atoms (particularly, sodium, potassium, magnesium, ammonium, mono-, di- and tri-sulfurs thereof). Ethanolamine salt), N-acyl sarcosine salts such as sodium lauroyl sarcosine, N-myristoyl-N-methyl taurine sodium, coconut oil fatty acid methyl tauride sodium, higher fatty acid amide sulfonates such as sodium lauryl methyl tauride, poly Oxyethylene (hereinafter referred to as “POE”) oleyl ether sodium phosphate, phosphate ester salts such as POE stearyl ether phosphate, sodium di-2-ethylhexylsulfosuccinate, monolauroyl monoethanolate Sulfosuccinates such as sodium dopolyoxyethylene sulfosuccinate and sodium lauryl polypropylene glycol sulfosuccinate, sodium linear dodecyl benzene sulfonate, triethanolamine linear dodecyl benzene sulfonate, alkyl benzene sulfonates such as linear dodecyl benzene sulfonic acid, N- N-acylglutamate such as monosodium lauroylglutamate, disodium N-stearoylglutamate, monosodium N-myristoyl-L-glutamate, higher fatty acid ester sulfates such as hydrogenated coconut oil fatty acid sodium glycerol sulfate, POE alkyl ether carboxylic acid , POE alkyl allyl ether carboxylate, α-olefin sulfonate, higher fatty acid ester sulfonate, Examples thereof include secondary alcohol sulfates, higher fatty acid alkylolamide sulfates, sodium lauroyl monoethanolamide succinate, and ditriethanolamine N-palmitoyl aspartate. Among these, alkyl sulfate ester salts, alkyl ether sulfate ester salts, higher fatty acid amide sulfonates, N-acyl glutamates, and the like are particularly preferably used.

  Examples of amphoteric surfactants include 2-undecyl-N, N, N- (hydroxyethylcarboxymethyl) -2-imidazoline sodium, 2-cocoyl-2-imidazolinium hydroxide-1-carboxyethyloxy-2 Betaine surfactants such as sodium salt imidazoline-based amphoteric surfactants, 2-heptadecyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, lauryldimethylaminoacetic acid betaine, alkylbetaines, amide betaines, sulfobetaines, etc. Agents and the like. Among these, 2-undecyl-N, N, N- (hydroxyethylcarboxymethyl) -2-imidazoline sodium, lauryldimethylaminoacetic acid betaine, amide betaine and the like are particularly preferably used.

  In the present invention, one or more surfactants selected from the above-mentioned anionic surfactants and / or amphoteric surfactants are contained in the hair cleansing composition of the present invention in an amount of 20 to 60%, preferably 30%. Add 50% by weight. If the amount of these surfactants is less than 20% by weight, the foaming property is poor. On the other hand, if it exceeds 60% by weight, the detergency is too strong, the hair is excessively degreased, and the hair becomes dry after drying. To do.

  Next, the polyglycerin having an average degree of polymerization calculated from the hydroxyl value of glycerin and / or its dehydration condensate of 3 or less used in the present invention is glycerin usually used in cosmetics, and the glycerin is used as a raw material. , Polyglycerin obtained by dehydration condensation reaction, such as diglycerin and triglycerin. When a fatty acid ester synthesized using polyglycerin having an average degree of polymerization exceeding 3 is blended in the hair cleaning composition, there is a problem that the hair after washing is stiff, such being undesirable.

  The hydroxystearic acid and oleic acid used in the present invention are not particularly limited, and the odor and hue of the resulting fatty acid ester are preferable as long as they are usually used in cosmetics. In addition, if the origin is plant-based, animal-derived raw materials are still more preferable as a shy cosmetic raw material.

  Next, as (1) hydroxystearic acid ester used in the present invention, with respect to 1.0 mol of polyglycerin having an average degree of polymerization calculated from a hydroxyl value of the above glycerin and / or dehydration condensate thereof of 3 or less, Hydroxy stearic acid ester obtained by esterifying 0.5 to 2.0 mol, preferably 1.0 to 1.5 mol, of hydroxy stearic acid. The feed ratio of the hydroxy stearate ester of (1) is preferably in the above range. When an ester obtained with a hydroxystearic acid of less than 0.5 is blended in a hair cleansing composition, the effect of imparting a “moist and cohesive feeling” after drying is reduced. On the other hand, when the amount exceeds 2.0 mol, a feeling of residual oil after drying, that is, an oily stickiness is developed, which is not preferable.

  The (2) oleic acid ester used in the present invention is oleic acid with respect to 1.0 mol of polyglycerin having an average degree of polymerization calculated from the hydroxyl value of the above glycerin and / or dehydration condensate thereof of 3 or less. Is an oleic acid ester obtained by esterifying 0.5 to 2.0 mol, preferably 0.5 to 1.5 mol. The charge ratio of the oleic acid ester (2) is preferably in the above range. If the oleic acid is less than 0.5, a squeaky feeling during rinsing will appear. On the other hand, if it exceeds 2.0 moles, the feeling of slime during rinsing becomes too strong, and rinsing becomes difficult.

  In the present invention, (1) the hydroxy stearic acid ester and (2) the oleic acid ester are used, and the weight ratio of (1) and (2) is 3.0: 7.0 to 7.0: 3.0. Certain fatty acid ester mixtures are used. The weight ratio of the hydroxystearic acid ester of (1) and the oleic acid ester of (2) is outside the above range, for example, a fatty acid ester mixture in which the amount of hydroxystearic acid ester is increased (the amount of oleic acid ester is reduced) When blended in the composition, a squeaky feeling during rinsing is developed. Conversely, when the amount of oleic acid ester is increased (the amount of hydroxystearic acid ester is decreased), the effect of imparting a “moist and coherent feeling” after drying is reduced.

  Further, in the present invention, the weight ratio of (1) and (2), which is composed of (1) hydroxystearic acid ester and (2) oleic acid ester, is 3.0: 7.0 to 7.0: 3. 0.1 to 10.0% by weight of the fatty acid ester mixture of 0 is blended into the hair cleansing composition. If it is less than 0.1% by weight, the effect of the present invention (effect of imparting a sufficiently moist and coherent feeling to the hair and suppressing the squeaky feeling during rinsing) does not appear. On the other hand, if the blending amount exceeds 10.0% by weight, a feeling of residual oil after drying, that is, oily stickiness appears, which is not preferable. Moreover, it exists in the tendency for the foamability of a hair cleaning composition to fall.

  In the hair cleansing composition of the present invention, components used in normal hair cleansing compositions and the like within a range not impairing the effects of the invention, for example, hydrocarbons such as liquid paraffin and squalane, oils such as ester oil, Viscosity modifiers such as methylcellulose, hydroxyethylcellulose, carboxymethylcellulose, ethanol, etc., for example, preservatives, antioxidants, sequestering agents, ultraviolet absorbers, powders, drugs (eg zinc pyrithione, trichlorocarbanilide), natural extracts, A coloring agent, a fragrance | flavor, etc. can be mix | blended suitably.
