Description

[0001] CONDITIONING SAMPOO COMPOSITION [0002]

The present invention relates to a conditioning shampoo composition, and more particularly, to a conditioning shampoo composition having excellent stability in the recovery of physical condition of the hair surface, prevention of further damage to damaged hair, and excellent hair conditioning.

Shampoo is a hair care cosmetic used to remove the contamination of scalp and hair and keep hair clean and beautiful. It is easy to combing, softness, smoothness, shine, reduction of friction of hair surface, anti-static, hair protection And so on.

Modern shampoos contain cationic surfactants, cationic polymers or silicones as conditioning agents to impart a conditioning effect.

The cationic surfactant acts to lower the friction force at the time of rinsing the hair to smooth it and to increase the hair adsorption of other water-insoluble conditioning materials. Unlike cationic polymers, however, they stimulate the scalp and tend to precipitate by forming complexes with anionic polymers used as stabilizers.

Silicon is often used to provide conditioning effects, but it is difficult to apply to real products. That is, if a small amount of silicone is used, stiffness is induced in the hair under rinsing and wet conditions, and bubble power is reduced and product stability is reduced. U.S. Patent Nos. 4,364,837, 4,341,799 and 4,465,639 disclose shampoo compositions containing silicone, but there is a limit to solving the stiffness of hair when using shampoo.

In addition, International Patent Publication No. 9210162 discloses a shampoo composition using silicone in combination with a cationic polymer, and U.S. Patent No. 4,704,271 discloses a shampoo composition using silicone with quaternary ammonium or amine having three long chain alkyl groups EP 0312234 discloses a shampoo composition comprising silicone and a long chain acyl derivative or amine oxide, US Patent No. 5,034,218 discloses a shampoo composition containing silicon and quaternary nitrogen having two long chain alkyl groups, US-A-2164558 discloses compositions comprising cationic silicon and amino aliphatic heteropolysaccharides. These patents are characterized by the use of cationic components to enhance adsorption and conditioning effects on the hair, but these components can bind to the hair and scalp in an electrically strong bond that can not be easily cleaned and can be cumulatively adsorbed (Chemical and Physical Behavior of Human Hair, 3 ^rd ED., Clarence R. Robbins, Springer Verlag, p. 177), causing troubles such as scalp itching, and still have the disadvantage that the hair becomes stiff during shampooing.

The oil with excellent conditioning effect on the hair has a great influence on the stability of the product. However, oils that do not affect the stability of the product are less effective in conditioning the hair, and oils that have better conditioning effects on the hair can affect the stability of the product by decreasing the viscosity of the product.

Therefore, there has been a long demand for a conditioning shampoo composition which has less irritation to the scalp and has excellent conditioning effect on the hair, and which has excellent stability of the product.

It is therefore an object of the present invention to provide a conditioning shampoo composition which is capable of reducing the stiffness of the hair during scalp stimulation and shampooing while at the same time providing a conditioning effect to dry hair while still providing a stable conditioning shampoo composition.

In order to achieve the above object, the present invention provides a cosmetic composition comprising an amino acid or carboxylate cosurfactant (used singly or in combination of two or more amino acid or carboxylate co-surfactants); A thickening agent, and optionally an ester or ether-based oil (either alone or in admixture of two or more ester-based or ether-based oils).

More preferably, the present invention relates to a composition comprising said composition in an amount of 0.1 to 20% by weight, based on the total weight of the composition, of an amino acid or carboxylate co-surfactant (alone or in combination); From 0.1 to 20% by weight of an incrementing agent; 0.05 to 5% by weight of an ester-based or ether-based oil (alone or in combination); 1 to 30% by weight of an anionic surfactant; And 0.01 to 1.0% by weight of a cationic polymer. The present invention also provides a conditioning shampoo composition.

The present invention also relates to amino acid- or carboxylate-based cosurfactants (alone or in combination); A method of making a conditioning shampoo composition comprising a thickener and optionally an ester or ether oil (alone or in combination)

(S1) mixing and stirring the cationic polymer with water;

(S2) mixing and stirring an anionic surfactant and an amino acid-based or carboxylate-based cosurfactant (alone or in mixture) to the mixture of (S1);

(S4), and (S3), and agitating the mixture of the thickening agent and the thickening agent.

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

The present inventors have studied how to reduce the stiffness of hair during use of shampoos, including oil and / or cosurfactants, while the oil and / or cosurfactant has the disadvantage of deteriorating the stability . More specifically, cosurfactant is typically an amino acid or carboxylate surfactant and has been used as an ancillary role in conventional anionic surfactants. Although these cosurfactants are less irritating than conventional anionic surfactants and have been known to have excellent conditioning effect on hair, they are difficult to use because they lower the viscosity of the product when they are used in a large amount. In case of oil, the stability of the shampoo composition It has a bad influence.

The present invention solves the above problems by using the thickening agent to improve the above-mentioned problems related to the stability. It is also confirmed that the conditioning shampoo composition having the same composition as the present invention has excellent side effects such as conditioning effect and scalp irritation The present invention has been completed based on this finding.

Accordingly, the present invention provides a conditioning shampoo composition comprising an amino acid or carboxylate co-surfactant (alone or in admixture) and an thickening agent, or an amino acid or carboxylate co-surfactant, Or an ether-based oil (alone or in combination). The present invention also provides a conditioning shampoo composition.

The conditioning shampoo composition of the present invention comprises an amino acid-based or carboxylate-based cosurfactant.

The content of the cosurfactant is preferably 0.1 to 20% by weight based on the total weight of the shampoo composition. If the content of the cosurfactant is less than 0.1% by weight, the conditioning effect may be insufficient. If the content of the cosurfactant exceeds 20% by weight, the viscosity of the product may be too low.

The conditioning shampoo composition of the present invention comprises a thickening agent. The thickening agent of the present invention is used for enhancing the stability of the product by increasing the viscosity of the product and maintaining the viscosity at the time of aging. A sorbitan derivative is preferable, and polyethylene glycol-160 sorbitan triisostearate (PEG-160 sorbitan triisostearate) Is more preferable.

The thickening agent is excellent in the thickening effect due to the use of the conditioning oil and / or the auxiliary surfactant and prevents the viscosity from decreasing over time, thereby improving the stability of the product.

Such thickening agent is preferably contained in an amount of 0.1 to 20% by weight based on the total weight of the conditioning shampoo composition. If the content of the thickening agent is less than 0.1% by weight, the effect of increasing is insufficient. If the content of the thickening agent is more than 20% by weight, the viscosity of the thickening agent is too high.

The shampoo composition of the present invention may also optionally further comprise an ester-based or ether-based oil. The oil is used to reduce stiffness in the wet and dry state of the hair to facilitate combing and to provide a conditioning effect to the hair. Examples of the ester-based or ether-based oil include dipropylene glycol-2-myristyl alcohol-10 adipate, dipropylly ether, diisopropyl adipate, Diisopropyl adipate, Ethylhexyl palmate, etc. may be used alone or in combination. Usually, the ether and ester-based conditioning oils which can be used in shampoos are not limited in use.

The conditioning oil is preferably included in an amount of 0.05 to 5% by weight based on the total weight of the shampoo composition. If the content of the oil is less than 0.05% by weight, the conditioning effect may be insufficient. If the oil content exceeds 5% by weight, the bubble power may be abruptly reduced.

The conditioning shampoo compositions of the present invention may also comprise cationic polymers and anionic surfactants customarily used in conditioning shampoo compositions.

The anionic surfactant included in the shampoo composition of the present invention is preferably sodium lauryl sulfate, ammonium lauryl sulfate, sodium polyoxyethylene lauryl sulfate, ammonium polyoxyethylene lauryl sulfate, and mixtures thereof, but is not limited thereto .

The anionic surfactant may be contained in an amount of 1 to 30% by weight based on the total weight of the conditioning shampoo composition. If the content of the anionic surfactant is less than 1% by weight, the detergency is poor. If the content is more than 30% by weight, the conditioning effect may be deteriorated.

Examples of the cationic polymer included in the shampoo composition of the present invention include reaction products of quaternary ammonium polymerized with acrylamide and dimethyldiallylammonium chloride, such as polyquaternium-7, trimethylammonium-substituted epoxide, For example, polyquaternium-10, guar hydroxypropyl trimonium chloride, for example, jucia C17, mixtures thereof, etc., may be used, but the reaction product of quaternary ammonium polymerized with hydroxyethyl cellulose may be used, But is not limited thereto.

The cationic polymer may be contained in an amount of 0.01 to 1% by weight based on the total weight of the conditioning shampoo composition. If the content of the cationic polymer is less than 0.01% by weight, the conditioning effect may be insufficient. If the content is more than 1% by weight, have.

Accordingly, the conditioning shampoo composition of the present invention may contain 0.1 to 20% by weight of amino acid or carboxylate co-surfactant alone or in combination with respect to the total weight of the composition; From 0.1 to 20% by weight of an incrementing agent; Optionally 0.05 to 5% by weight of ester or ether-based oil alone or in admixture; 1 to 30% by weight of an anionic surfactant; And 0.01 to 1.0 wt% of the cationic polymer.

The conditioning shampoo composition of the present invention may further comprise an auxiliary component commonly used in shampoos such as fragrances, pigments, preservatives, and pH adjusting agents in addition to the above components to the extent that the object of the present invention is not impaired.
