Description

Conditioning shampoo composition

The present invention includes an anionic detergent and a cationic polymer, including oils or aromatic oils (essential oils or essential oils) obtained from plant roots, stems, leaves, flowers, shells, fruits, etc., or oils or oils obtained from animals as conditioning ingredients. To a conditioning shampoo composition which forms coacervate by.

In recent years, the hair is damaged by various physical and chemical factors such as frequent combing, perm, and dyeing, thereby increasing the roughness and losing the gloss, causing the softness and softening effect to occur frequently. As a result, it becomes difficult to care for hair, and problems such as hair cut or split ends occur.

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 hair, prevent damage and impart conditioning effect to shampoos that used anionic surfactants as a main ingredient to remove contamination of hair and scalp by emphasizing only cleaning functions, In addition to the surfactant of the so-called conditioning shampoos further added to the conditioning agent has been developed and put to practical use, the use is increasing trend.

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.

In addition, US Patent Nos. 5,104,646 and 6,930,078 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 use silicones or synthetic oils, which may cause scalp irritation due to cumulative adsorption, and also provide conditioning effects by simple addition of these conditioning ingredients or coacervate generation by simple combination of anionic detergent and cationic polymer. It has a disadvantage in that the amount of coacervate produced is not large and therefore the conditioning effect is weak.

Accordingly, the technical problem to be achieved by the present invention is to use vegetable and / or animal natural oils and / or fats and oils as conditioning ingredients of shampoos to provide conditioning effects by natural substances, while maximizing coacervate formation to improve reverberation and It is to provide a conditioning shampoo composition that can improve the conditioning effect.

In order to achieve the above technical problem, the present invention is an anionic surfactant; Cationic polymers; And a conditioning shampoo composition comprising any one or more conditioning ingredients selected from the group consisting of vegetable oils, vegetable oils, animal oils and animal oils, comprising a quaternary ammonium cationic surfactant represented by the following formula (1): It provides a conditioning shampoo composition.

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 conditioning 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 relative to the total weight of the shampoo composition.

More preferably, the present invention provides a conditioning shampoo composition, characterized in that the content of the cationic polymer in the above-described conditioning shampoo composition is 0.01 to 5% by weight relative to the total weight of the shampoo 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, a conditioning shampoo composition comprising the vegetable oil, vegetable oil, animal oil or animal oil of the present invention as a conditioning component will be described in more detail.

The conditioning shampoo composition of the present invention includes a cationic surfactant of a specific formula into which a glyceryl group represented by 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 is a quaternary ammonium compound structure, in which one substituent of ammonium ion has an alkylamido group, two substituents have a methyl group, and the other 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 alkylamido 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 addition, even in the presence of anionic surfactants, the amount of cationic polymer used may be further increased, and as a result, it may have a special function of generating more coacervate, which is a complex of anionic surfactant and 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 oils and / or oils obtained from plants or animals for providing conditioning effects to hair and scalp. Fats and oils obtained from these natural oils or vegetable fragrance oils or animals can provide natural mild conditioning and aroma effects to hair and skin, and at the same time reduce irritation by cumulative adsorption.

Such natural oils or vegetable fragrance oils or fats and oils are not particularly limited as long as they can be commonly used in detergent compositions, for example, vegetable oils, vegetable fragrance oils, vegetable oils, animal oils, animal oils and the like derived from nature Oils and / or fats and oils may be selected and used.

Vegetable oils that may be included in the conditioning shampoo composition of the present invention include, for example, avocado oil, almond oil, sweet almond oil, bitter almond oil, olive oil, sesame oil, rice brand oil, safflower oil, soybean oil. , Corn oil, cannula oil, apricot kernel oil, pitch kernel oil, palm kernel oil, palm oil, castor oil, sunflower seed oil, grape seed oil, cotton seed oil, coconut oil, camellia oil, peach seed oil, apricot seed One or more oils may be used, but is not limited thereto.

In addition, vegetable fragrance oils that may be included in the conditioning shampoo composition of the present invention to improve the fragrance and aid the conditioning effect, for example, orange oil, lavender oil, jasmine oil, lime oil, bergamot oil, lemon oil, rose Oil, sandalwood oil, geranium oil, cypress oil, frankinsens oil, eucalyptus oil, clary sage oil, eucalyptus oil, rosemary oil, chamomile oil, tea tree oil, lily oil, mint oil, pine oil, mandarin green oil, One or more kinds of neroli oil may be used, but is not limited thereto.

In addition, animal oils or fats and oils that may be included in the conditioning shampoo composition of the present invention, for example, tallow, larch, sunny, hardened oil, horse oil, mink oil, egg yolk fatty oil may be used, but is not limited thereto. no.

In the conditioning shampoo composition of the present invention, the total content of the oil and the oil is preferably 0.1 to 5% by weight, more preferably 0.5 to 3% by weight based on the total weight of the shampoo 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 the stability of the formulation and the contents.

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 shampoo 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 Ammonium and the like may be used one or more, 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 amppocarboxy glycinate, sacosinate and the like may be used, but is not limited thereto. no.

The conditioning shampoo composition of the present invention may further contain one or more conditioning agents selected from the above cationic polymers, silicone compounds and oils in order to further improve the conditioning effect in addition to the natural oil or fat or oil components.

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

The oil-based oil that can be additionally 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, etc. can be used (Hydrogenated Polydecene), and ester oils include myristic acid isopropyl, palmitic acid isopropyl, stearic acid, isostearyl, _-15 C ₁₂ alkyl Benzoate and the like may be used, but is not limited thereto.

<Evaluation of coacervate production amount>

In order to measure the amount of coacervate produced to enhance hair adsorption of the conditioning component, the concentration using the actual shampoo was determined to be 10% by weight of shampoo. The resulting coacervate was centrifuged (3,000 rpm, 30 minutes), the supernatant was discarded, and the precipitated portion was taken to determine the amount of coacervate produced. In some cases, when the coacervate production concentration is 10% or less, since it is easy to be washed off when rinsing using the actual shampoo, the present invention is based on 10% by weight of the shampoo. The results are shown in Table 2 below.

<Evaluation of Conditioning Effect of Shampoo>

Ninety women who had experience in sensory evaluation of hair products were evaluated to have a hair texture after using the shampoos prepared in Examples 1-5 and Comparative Examples 1-5, respectively, by ten persons using conventional shampoos. 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, 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 compared to the comparative examples including the alkyl glyceryl quaternary ammonium cation surfactant or the conventional cationic surfactant of 3.

In addition, when the amount of coacetate produced was large, the hair feel was also excellent by the hair adsorption of vegetable oil and / or animal oil or oil after shampooing. However, in the case of Comparative Example 3, the amount of coacetate produced was large, but the physical properties of the coacetate produced were so solid-like that avocado oil used as a conditioning component was not effectively adsorbed, and thus did not show a good result for hair texture.

As described above, the conditioning shampoo composition of the present invention contains a cationic surfactant in the form of quaternary ammonium having a specific chemical structure, which is not only excellent in feeling but also can greatly increase the amount of coacetate produced. The amount of hair adsorption can be increased to exhibit excellent hair conditioning effect.
