Description

Technical Field

[0001] The present invention relates to a composition for keratin fibers, specifically a hair care composition, comprising at least one betaine compound, and to a beauty method using said composition.

Background Art

[0002] It is well known that the smoothing and softening effects of hair-related products are widely preferred by customers. It is also well known that hair conditioners are recommended for the treatment of damaged hair that has been sensitized (i.e., damaged and / or embrittled) to varying degrees under the action of atmospheric substances or under the action of mechanical or chemical treatments (such as dyeing, bleaching and / or permanent wave operations, etc.). Damaged hair is difficult to detangle and often lacks softness. It is well known in the art to use hair conditioners in compositions for hair washing or care in order to facilitate detangling of the hair and achieve softening and smoothing effects.

[0003] Some prior arts disclose compositions for the care of keratin fibers.

[0004] For example, WO2013 / 189037 discloses a personal care composition comprising a pearlescent conditioning composition, comprising: a) at least one fatty alcohol containing a fatty chain of at least 22 carbon atoms, b) at least one fatty amide, c) at least one alkyl polyglycoside, and d) at least one conditioning agent.

[0005] However, there is still a need for cosmetic compositions having an increased viscosity, which can provide an improved conditioning effect, such as the effect of imparting softness and smoothness to keratin fibers, and the viscosity is the key to giving customers a signal of restoration.

[0125] - Hydrophilic thickener The composition according to the present invention may contain at least one hydrophilic thickener. A single type of hydrophilic thickener, or a combination of different types of hydrophilic thickeners, can be used.

[0126] The term "hydrophilic" as used herein means a substance that is soluble in water at a concentration of 1% by mass or more based on the total mass of water at room temperature (25°C) and atmospheric pressure (10 5 Pa).

[0127] The hydrophilic thickener may be a natural or synthetic hydrophilic thickener. The hydrophilic thickener may preferably be selected from thickening polymers that retain sugar units, for example, non - associative thickening polymers that retain sugar units.

[0128] For the purposes of the present invention, the term "sugar unit" means a hydrocarbon - based compound that contains several alcohol functional groups, contains at least 4 carbon atoms, and retains oxygen, regardless of the presence or absence of an aldehyde or ketone functional group.

[0129] The sugar unit may optionally be modified by substitution and / or oxidation and / or dehydration.

[0130] The sugar units that may be included in the composition of the hydrophilic thickening polymer of the present invention preferably are derived from the following sugars: glucose, galactose, arabinose, rhamnose, mannose, xylose, fucose, galactose anhydride, galacturonic acid, glucuronic acid, mannuronic acid, galactose sulfate, galactose anhydride sulfate, and fructose.

[0131] It is preferred that the thickener be selected from polysaccharides.

[0134] Examples of chemical treatments that can be mentioned include esterification, etherification, amidation and oxidation reactions. These treatments can result in polymers that can be, in particular, nonionic, anionic or amphoteric.

[0135] Preferably, the thickening polymer that retains the sugar units is not chemically or physically treated.

[0136] The non-ionic guar gum that can be used according to the present invention can be modified with a C1-C6 (poly) hydroxyalkyl group.

[0137] Among the C1-C6 (poly) hydroxyalkyl groups, for example, hydroxymethyl, hydroxyethyl, hydroxypropyl, and hydroxybutyl groups can be mentioned.

[0138] These guar gums are well-known in the prior art and can be prepared, for example, by reacting a corresponding alkene oxide, such as propylene oxide, with guar gum to obtain a guar gum modified with a hydroxypropyl group.

[0139] The degree of hydroxyalkylation is preferably in the range from 0.4 to 1.2 and corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functional groups present in the guar gum.

[0140] Such non-ionic guar gums optionally modified with a hydroxyalkyl group are sold, for example, under the trade names Jaguar HP8, Jaguar HP60, and Jaguar HP120 by Rhodia Chimie.

[0141] Among the starches that can be used are, for example, polymers in the form of polymers containing base units that are anhydroglucose units. The number of these units and their assemblies make it possible to distinguish between amylose (linear polymer) and amylopectin (branched polymer). The relative ratio of amylose and amylopectin, as well as their degree of polymerization, can vary depending on the plant origin of the starch.

[0142] The plant origin of the starch molecules that may be used in the present invention can be cereals or tubers. Thus, the starch can be selected, for example, from maize starch, rice starch, cassava starch, barley starch, potato starch, wheat starch, sorghum starch and pea starch.

The anionic groups and the cationic groups may be bonded to the same reaction site or different reaction sites of the starch molecule; preferably, they are bonded to the same reaction site. The anionic group can be of the carboxyl, phosphate or sulfate type, preferably of the carboxyl type. The cationic group can be of the primary, secondary, tertiary or quaternary amine type.

[0145] The starch may optionally be C1-C6 hydroxyalkylated or C1-C6 acylated (e.g., acetylated). The starch may also have been subjected to heat treatment.

[0146] The non-associating thickening polymer of the present invention can be a cellulose-based polymer that does not contain C 10 ~C 30 fatty chains.

[0147] According to the present invention, the term "cellulose-based polymer" means any polysaccharide compound having a sequence of glucose residues covalently bonded together via β-1,4 linkages in its structure, and in addition to unsubstituted cellulose, cellulose derivatives can be anionic, cationic, amphoteric or non-ionic.

[0148] Thus, the cellulose polymers that may be used in accordance with the present invention may be selected from unsubstituted cellulose in microcrystalline form, and cellulose ethers.

[0149] Among these cellulose-based polymers, cellulose ethers, cellulose esters, and cellulose ester ethers are well known.

[0150] Among cellulose esters, there are inorganic cellulose esters (such as cellulose nitrate, sulfate, phosphate, etc.), organic cellulose esters (such as cellulose monoacetate, triacetate, amide propionate, acetate butyrate, acetate propionate, and acetate trimellitate, etc.), and organic / inorganic mixed esters of cellulose, such as cellulose acetate butyrate sulfate and cellulose acetate propionate sulfate.

[0152] Among anionic cellulose ethers having no fatty chain, (poly)carboxy(C1-C4)alkyl cellulose and their salts can be mentioned. Examples include carboxymethyl cellulose, carboxymethyl methyl cellulose (e.g., Blanose 7M manufactured by Aqualon), carboxymethyl hydroxyethyl cellulose, and their sodium salts.

[0153] Among cationic cellulose ethers having no fatty chain, cationic cellulose derivatives, for example, cellulose copolymers or cellulose derivatives grafted with water-soluble quaternary ammonium monomers, such as those described in Patent US4,131,576, for example, (poly)hydroxy(C1-C4)alkyl cellulose grafted with methacryloylethyltrimethylammonium, methacrylamidopropyltrimethylammonium, or dimethyldiallylammonium salts, such as hydroxymethyl-, hydroxyethyl-, or hydroxypropyl cellulose, can be mentioned. Commercially available products corresponding to this definition are, more specifically, products sold under the names Celquat L 200 (registered trademark) and Celquat H 100 (registered trademark) by National Starch.

[0154] The degree of hydroxyalkylation corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functional groups present in guar gum, and may be, for example, in the range of 0.4 to 1.2.

[0155] The amount of the hydrophilic thickener in the composition according to the present invention may be in the range of 0.1% by mass to 10% by mass, preferably 0.3% by mass to 5% by mass, more preferably 0.5% by mass to 3% by mass, based on the total mass of the composition.

Examples

[0248] The present invention will be described in more detail by way of examples. However, they should not be construed as limiting the scope of the present invention.

[0249] [Preparation] Each of the compositions in the form of an O / W emulsion according to Example 1 and Comparative Examples 1 and 2 was prepared by mixing the components shown in Table 1. When dissolving behenyl alcohol and thickeners, etc., the components were heated up to a maximum of 70 °C until completely dissolved. The numerical values of the amounts of the components in Table 1 are all based on the "mass %" of the components with respect to the total mass of each composition, unless otherwise indicated (AM: active substance).

[0250] [Evaluation] (Viscosity) The viscosity of the obtained composition was measured at 25 °C using a Rheomat RM 180 rheometer equipped with a spindle No. 4. After rotating the spindle in the composition at 200 rpm for 1 minute, measurements were taken for 30 seconds.

[0251] (Sensory evaluation) 2.7 g of bleached Chinese hair bundles with a length of 27 cm were prepared. Each hair bundle was washed once with a clarifying shampoo. After shampooing, the hair bundles were rinsed with water and dried with a towel. 1 g of each composition according to Example 1 and Comparative Examples 1 and 2 was applied onto the hair bundles, and then the hair bundles were left under ambient conditions for 5 minutes. Then, the hair bundles were rinsed off with water and dried with a dryer to obtain the treated hair bundles.

[0252] The sensory aspects of the softness and smoothness of the treated hair were evaluated by several judges in the hair care field by ranking them from 1 to 3 according to the following criteria and averaging.

[0253] - Softness 1: The softness of the hair was not recognized. 2: The softness of the hair was slightly recognized. 3: The softness of the hair was fully recognized.

[0254] - Smoothness 1: The smoothness of the hair was not recognized. 2: The smoothness of the hair was slightly recognized. 3: The smoothness of the hair was fully recognized.

[0255] The results are shown in Table 1 below.

[0256]

Table 1

[0257] As can be confirmed from the table, the composition according to Example 1, which contains a specific combination of components (a) to (d), showed improved softening and smoothing effects and an increased desired viscosity. Since the composition shows an improved conditioning effect, such as the effect of imparting softness and smoothness to keratin fibers, it can be said that the keratin fibers are not made sticky.

[0258] On the other hand, the composition according to Comparative Example 1, which does not contain the (d) betaine compound, could not show good softening and smoothing effects on keratin fibers. In addition, the viscosity of the composition according to Comparative Example 1 was not sufficient. Also, the composition according to Comparative Example 2, which contains only 1% by mass of the betaine compound, could not show good softening and smoothing effects on keratin fibers. In addition, the viscosity of the composition according to Comparative Example 2 was not sufficient.

[0259] Accordingly, the composition according to the invention can bring about an improved cosmetic effect of softening and smoothing keratin fibers, and can exhibit an increased desired viscosity without making the hair limp, so that it can be said to be very suitable as a cosmetic composition for treating keratin fibers such as hair.
