Description

Conditioning shampoo composition

The present invention relates to a conditioning shampoo composition in which the amount of coacervate produced by the anionic detergent and the cationic polymer is increased.

Recently, hair is damaged by various physical and chemical factors such as frequent combing, perm, and dyeing, so that roughness increases, loss of luster, and softness and softening effect are frequently caused. As a result, it becomes difficult to care for the hair and causes problems such as hair being cut or splitting ends.

In order to solve this problem, there has been a continuous study of cleaning agents or hair conditioning ingredients to improve the softness of the hair at the time of cleaning or after cleaning and to restore damaged hair. In particular, in order to protect the hair, prevent damage and impart conditioning effect to the shampoo that used to be an anionic surfactant as a main ingredient to remove the contamination of the hair and scalp in the past by emphasizing only the cleaning function, In addition to surfactants, so-called conditioning shampoos having further added a conditioning agent have been developed and put into practical use, and their use is increasing.

Korean Patent Laid-Open Publication No. 10-0316976 uses a silicone compound such as a water-insoluble nonvolatile dimethicone, cyclomethicone, amino silicone, amodimethicone, trimethylsilyl amodimethicone and derivatives thereof as a hair conditioning component. Doing.

Recently, US Pat. Nos. 5,104,646, 6,930,078 and the like have attempted to increase the conditioning effect by increasing the adsorption of hair conditioning components such as silicone to the hair using coacetate produced by anionic surfactants and cationic polymers. However, they provide a conditioning effect by simply adding a conditioning component or by generating a coacervate by a simple combination of an anionic detergent and a cationic polymer, which has a disadvantage in that the amount of coacetate is not generated and thus the conditioning effect is weak.

Therefore, the technical problem to be achieved by the present invention is to provide a conditioning shampoo composition that can optimize the conditioning effect by maximizing the coacervate formation at the same time to improve the comfort to solve the above problems.

In order to achieve the above technical problem, the present invention in a conditioning shampoo composition comprising an anionic surfactant, a cationic polymer and a conditioning agent, comprising a glyceryl quaternary alkyl amido ammonium cationic surfactant represented by the following formula (1) It provides a conditioning shampoo composition, characterized in that:

In Formula 1, R is any one selected from the group consisting of a linear alkyl group, branched alkyl group and alkenyl group having 12 to 22 carbon atoms, n is an integer of 0 to 10, X is a halogen group element, sulfate group and acetate It is any one selected from the group consisting of groups.

More preferably, the present invention provides a shampoo composition, characterized in that the content of the quaternary ammonium cationic surfactant in the above-described conditioning shampoo composition is 0.1 to 10% by weight based on the total weight of the composition.

More preferably, the present invention provides a conditioning shampoo composition according to the above-described conditioning shampoo composition, wherein the composition comprises 0.01 to 5% by weight based on the total weight of the composition.

More preferably, the present invention provides a conditioning shampoo composition according to the above-described conditioning shampoo composition, wherein the charge density of the cationic polymer is 0.1 mEq / g to 1.3 mEq / g.

More preferably, the present invention provides a conditioning shampoo composition, wherein the cationic polymer has a molecular weight of 200,000 to 3,000,000 in the above-described conditioning shampoo composition.

Hereinafter, the conditioning shampoo composition of the present invention will be described in detail.

The conditioning shampoo composition of the present invention includes a cationic surfactant into which a glyceryl group represented by Chemical Formula 1 is introduced as a component that plays a role of conditioning and promotes formation of coacetate.

Referring to Formula 1, the cationic surfactant used in the present invention has a structure of a quaternary ammonium compound, wherein one substituent of ammonium ion has an alkyl amido group, two substituents have a methyl group, and the other one has a hydrophilic group. Is a structure in which at least one glyceryl group is condensed and repeated, and the number of repeating units is 1 to 11.

The quaternary ammonium cationic surfactant contains at least one glyceryl group, which is a hydrophilic group, and interacts with an anionic surfactant in an aqueous solution commonly referred to as pseudo-nonionic complex surfactant. Melting mixed micelles can be formed. Since the pseudo-nonionic complex surfactant improves the problems of high viscosity and precipitation that occur when the cationic polymer and the anionic surfactant are used simultaneously, the amount of the cationic polymer can be increased even in the presence of the anionic surfactant. will be.

In addition, the quaternary ammonium cationic surfactant of Formula 1 includes an alkyl amido group having a relatively hydrophilic property instead of a long chain fatty acid group, so that the mixed micelle formation ability of a pseudo-nonionic complex surfactant is better. In the presence of an anionic surfactant, the amount of the cationic polymer may be further increased, and as a result, it may have a special function of generating more coacervate, which is a complex of the anionic surfactant and the cationic polymer.

The quaternary ammonium cationic surfactant is preferably used 0.1 to 10% by weight based on the total weight of the composition. If the content is less than 0.1% by weight, it is difficult to achieve the conditioning effect and stability improvement effect by the quaternary ammonium cation surfactant. If the content is more than 10% by weight, the hair is damp and there is a fear of precipitation and phase stability. May be unsuitable for use.

The conditioning shampoo composition of the present invention essentially comprises a cationic polymer for producing coacervate. Coacervates are affected by various factors, but are known to be most affected by the content and structure of cationic polymers, in particular the molecular weight and positive charge density (mEq / g) of cationic polymers.

The cationic polymer is not particularly limited as long as it can be used in a shampoo composition, for example, may be used by selecting one or more from the group consisting of natural cationic polymer, synthetic cationic polymer and mixtures thereof. .

Natural cationic polymers that can be included in the conditioning shampoo composition of the present invention include, for example, cationic guar such as guar hydroxypropyltrimonium chloride, hydroxypropyl guar hydroxypropyltrimonium chloride, cellulose (polyquaternium- 10) may be used one or more, but is not limited thereto. Synthetic cationic polymers that may also be used in the conditioning shampoo composition of the present invention include, for example, dimethyldiallylammonium chloride polymer, acrylamide-dimethyldiallylammonium chloride copolymer, polyvinylpyrrolidone (PVP) -dimethyl One or more aminoethyl methacrylate copolymers, acrylic acid-dimethyldiallylammonium chloride copolymers, acrylamide-dimethylamino ethylmethacrylate methyl chloride copolymers, trimethylaminoethylmethacrylate polymers, etc. may be used. It doesn't happen.

In the conditioning shampoo composition of the present invention, the content of the cationic polymer is preferably 0.01 to 5% by weight relative to the total weight of the composition. If the content is less than 0.01% by weight, the production of coacervate is poor, and the conditioning effect due to lower adsorption of the conditioning component is not sufficiently exerted. If the content is more than 5% by weight, the conditioning component is excessively produced on the hair and the scalp. This is because excessive adsorption gives a bad feeling, that is, the feeling of use is bad.

In addition, the molecular weight of the cationic polymer included in the conditioning shampoo composition of the present invention is preferably 200,000 to 3,000,000. If the molecular weight is less than 200,000, coacervate is poorly produced and the adsorption of the conditioning component is lowered, so that the conditioning effect is not sufficiently exerted. If the molecular weight is over 3,000,000, the coarsenate is excessively adsorbed on the hair and the scalp. Because it gives a bad feeling.

In addition, the charge density of the cationic polymer of the present invention is preferably 0.1 mEq / g to 1.3 mEq / g. This resulted in no coacervate production when the charge density of the cationic polymer was less than 0.1 mEq / g, and coacervates produced using cationic polymers exceeding 1.3 mEq / g were too close to solid-gel for conditioning. This is because the ingredients do not help to adsorb to the hair and thus have no hair conditioning effect.

The conditioning shampoo composition of the present invention also includes an anionic surfactant as a cleaning component.

The anionic surfactant that can be used in the present invention is not particularly limited as long as it can be used in a conventional shampoo composition, the content of the anionic surfactant is preferably 1 to 50% by weight relative to the total weight of the composition. If the content is less than 1% by weight, the cleaning function is not properly exhibited, and if the content exceeds 50% by weight, the cleaning power may be excessive to give a rough feeling to the hair.

As the anionic surfactant that can be used in the present invention, for example, sodium lauryl sulfate, ammonium lauryl sulfate, magnesium lauryl sulfate, lauryl triethanolamine, sodium polyoxyethylene lauryl sulfate, polyoxyethylene lauryl sulfate One or more may be used, but is not limited thereto.

The conditioning shampoo composition of the present invention may further contain a nonionic surfactant and an amphoteric surfactant within the range of not impairing the object of the present invention for the purpose of increasing cleaning power and the like.

As the nonionic surfactant that may be used in the present invention, for example, lauryl acid diethanolamide, palm oil fatty acid diethanolamide, palm oil fatty acid monoethanolamide, and the like may be used, but are not limited thereto. In addition, as the amphoteric surfactant that can be used in the present invention, for example, betaine, amido propyl betaine, coco ampocarboxy glycinate, sacosinate and the like may be used, but is not limited thereto. no.

The conditioning shampoo composition of the present invention may contain one or more conditioning agents selected from the above cationic polymers, silicone compounds and oils in order to enhance the conditioning effect.

The silicone compound to be applied to the conditioning shampoo composition of the present invention is not particularly limited as long as it can be used in the shampoo composition, for example, water insoluble non-volatile dimethicone, cyclomethicone, aminated silicone, trimethylsilyl One or more components commonly referred to as silicones such as moditicone and vinyl silicone and derivatives thereof can be used.

When the silicone compound is used in the conditioning shampoo composition of the present invention, the content of the silicone compound is preferably 0.1 to 5% by weight, more preferably 0.5 to 3% by weight based on the total weight of the composition. This is because when the content is less than 0.1% by weight, a sufficient conditioning effect is not exerted, and when it is more than 5% by weight, there may be a problem in formulation formation.

The oily oil applied to the conditioning shampoo composition of the present invention is not particularly limited as long as it can be used in the shampoo composition, for example, hydrocarbon oil and synthetic ester oil and the like can be used. Hydrocarbon oils include liquid paraffin (Mineral Oil), iso-paraffin, hydrogenated polydecene (Hydrogenated Polydecene), etc. may be used, and ester oils include myristic acid isopropyl, palmitic acid isopropyl, a small stearate isostearyl, C ₁₂ - ₁₅ Alkyl benzoate or the like may be used, but is not limited thereto.

In addition to this, the shampoo composition according to the present invention may further contain additives such as preservatives, thickeners, viscosity adjusters, pH adjusters, fragrances, dyes, conditioning agents, etc., which can be commonly used as a component of the shampoo composition, which are commercially available. It can be easily purchased and used. Examples of the preservative include methyl paraoxybenzoate, methylchloroisothiazolinone and a mixture of methylisothiazolinone (trade name: Kathon CG, manufactured by Rohm & Haas, USA). Examples of the thickener and the viscosity modifier include hydroxypropyl methyl cellulose, hydroxymethyl cellulose, sodium chloride, ammonium chloride, propylene glycol, hexylene glycol, and the like. Citric acid, sodium hydroxide, triethanolamine, etc. are mentioned as a pH adjuster. Examples of the dyes include water-soluble tar pigments. Conditioning agents include animal and vegetable extracts, proteins and protein variants, and Fatty Acid.

Hereinafter, the present invention will be described in detail with reference to Examples. However, embodiments according to the present invention can be modified in many different forms, the scope of the present invention should not be construed as limited to the embodiments described below. The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.

<Evaluation of Conditioning Effect of Shampoo>

90 women who were experienced in sensory evaluation of hair products were subjected to the evaluation of hair texture after using the shampoos prepared in Examples 1 to 5 and Comparative Examples 1 to 5, respectively, by the usual method of using the shampoo. The evaluation method is 1 point for a very bad hair texture, 2 points for a bad hair texture, 3 points for a normal hair texture, 4 points for a good hair texture, and 5 points for a very good hair texture. The results are shown in Table 3 below.

As can be seen in Tables 2 and 3 above, the conditioning shampoo composition of the embodiments comprising the alkyl amido glyceryl quaternary ammonium cation surfactant of Formula 2 does not use a quaternary ammonium cation surfactant or It can be seen that the amount of coacervate produced is higher than that of comparative examples including an alkyl glyceryl quaternary ammonium cation surfactant of Formula 3 or a conventional cationic surfactant.

In addition, if the amount of coacervate produced was large, the hair feel after shampoo was also excellent. However, in the case of Example 5, the amount of coacetate produced is large, but the physical properties of the coacetate produced are so solid-like that the hair feel is rather poor.

As described above, the conditioning shampoo composition of the present invention contains a cationic surfactant in the form of a quaternary ammonium having a glyceryl group introduced therein, which is not only excellent in feeling but also greatly increases the amount of coacetate produced, and thus an excellent hair conditioning effect. Can be represented.
