Description

Conditioning shampoo composition {CONDITIONING SHAMPOO COMPOSITION}

The present invention relates to a conditioning shampoo composition, and more particularly, to a conditioning shampoo composition that has an excellent effect in restoring the physical state of the hair surface, preventing additional damage to damaged hair, and conditioning the hair while ensuring stability.

Shampoo is a hair-styling cosmetic used to remove contamination of the scalp and hair and keep the hair clean and beautiful.In addition to cleaning purposes, it is easy to comb, softens, gives smoothness, shine, reduces friction on the hair surface, prevents static electricity, protects hair. It is used for additional purposes such as.

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

Cationic surfactants lower the frictional force during hair rinsing to make them smooth and increase hair adsorption of other water-insoluble conditioning substances. However, unlike cationic polymers, it also irritates the scalp and tends to precipitate by forming a complex with anionic polymers used as stabilizers.

Silicone is often used to give conditioning effects, but it is difficult to apply to actual products. That is, if a small amount of silicone is used, there is a problem in that stiffness is caused in the hair in a rinsing and wet state, inhibiting the foaming force, and reducing product stability. 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 together with a cationic polymer, and U.S. Patent No. 4,704,271 discloses a shampoo composition using silicone together with quaternary ammonium or amine having three long-chain alkyl groups. , European Patent No. 0312234 discloses a shampoo composition containing silicone and a long-chain acyl derivative or amine oxide, U.S. Patent No. 5,034,218 discloses a shampoo composition containing silicone and quaternary nitrogen having two long-chain alkyl groups, and a British patent. No. 2164558 discloses a composition comprising a cationic silicone and an amino aliphatic heteropolysaccharide. The above patents use cationic ingredients to improve adsorption properties and conditioning effects on the hair, but these ingredients are strongly electrically bonded to the hair and scalp, so they are not easily cleaned and can be accumulated and adsorbed (Chemical and Physical Behavior of Human Hair, 3 ^rd ED., Clarence R. Robbins, Springer Verlag, p.177), it causes troubles such as itchy scalp, and still has the disadvantage of getting stiff hair while using shampoo.

Oils with excellent conditioning effects on hair have a great influence on the stability of products. However, oils that do not affect the stability of the product have poor conditioning effects on the hair, and oils that have excellent conditioning effects on the hair lower the viscosity of the product and affect the stability of the product.

Therefore, there has been a long demand for a conditioning shampoo composition having excellent product stability while using raw materials that have little irritation to the scalp and excellent hair conditioning effect.

Accordingly, an object of the present invention is to provide a conditioning shampoo composition that is stable while reducing scalp irritation and stiffness of the hair during shampoo use, and at the same time providing a conditioning effect to dry hair.

In order to achieve the above object, the present invention provides an amino acid-based or carboxylate-based auxiliary surfactant (one type alone or a mixture of two or more amino acid-based or carboxylate-based auxiliary surfactants); It provides a conditioning shampoo composition comprising a thickener and optionally an ester-based or ether-based oil (one type alone or a mixture of two or more types of ester-based or ether-based oils).

More preferably, the present invention comprises 0.1 to 20% by weight of an amino acid-based or carboxylate-based auxiliary surfactant (alone or mixed) based on the total weight of the composition; 0.1 to 20% by weight thickener; 0.05 to 5% by weight of ester or ether oil (alone or mixed); 1 to 30% by weight of anionic surfactant; And it provides a conditioning shampoo composition comprising 0.01 to 1.0% by weight of a cationic polymer.

The present invention also provides an amino acid-based or carboxylate-based auxiliary surfactant (alone or mixed); A method for preparing a conditioning shampoo composition comprising a thickener and optionally an ester-based or ether-based oil (alone or mixed),

(S1) mixing and stirring a cationic polymer in water;

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

(S3) After stirring by adding an ester-based or ether-based oil (alone or mixed) to the mixture of (S2), heating (e.g., 70℃±10℃, the temperature to be heated depends on the melting point of the thickener used) Varying) while stirring; And

(S4) A method for producing a conditioning shampoo composition comprising the step of mixing and stirring a thickener in the mixture of (S3).

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

The inventors of the present invention were researching a method that can reduce the stiffness of hair while using shampoo while containing oil and/or auxiliary surfactant, while oil and/or auxiliary surfactant lowers the temporal viscosity of the product and impairs stability. Found. More specifically, the auxiliary surfactant generally refers to an amino acid-based or carboxylate-based surfactant and has been used as an auxiliary role of the existing anionic surfactant. These auxiliary surfactants have been known to have less irritation than conventional anionic surfactants and have excellent conditioning efficacy for hair, but when they are actually used a lot, it is difficult to use them by lowering the viscosity of the product, and even in the case of oil, the stability of the shampoo composition Has a bad effect.

In the present invention, it was confirmed that the above problems related to stability can be improved by solving these problems by using a thickener, and the conditioning effect of the conditioning shampoo composition having the same composition as the present invention and side effects such as scalp irritation are excellent. And, based on this, the present invention was completed.

Accordingly, the present invention is a conditioning shampoo composition comprising an amino acid or carboxylate auxiliary surfactant (alone or mixed) and a thickener, or an amino acid or carboxylate auxiliary surfactant, a thickener and an ester It provides a conditioning shampoo composition comprising a system or an ether oil (alone or mixed).

The conditioning shampoo composition of the present invention contains an amino acid-based or carboxylate-based auxiliary surfactant. These auxiliary surfactants reduce irritation of existing anionic surfactants and can increase conditioning efficacy for hair. As auxiliary surfactants, sodium cocoyl glutamate, TEA-Cocoyl alaninate, sodium laureth-13 carboxylate, etc., alone or in combination It is preferable to use it, but is not limited thereto.

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

The conditioning shampoo composition of the present invention includes a thickener. The thickener of the present invention is used to improve the stability by increasing the viscosity of the product and maintaining the viscosity over time, and a sorbitan derivative is preferable, and polyethylene glycol-160 sorbitan triisostearate (PEG-160 sorbitan triisostearate) Is more preferred.

The thickener has excellent thickening effect due to the use of a conditioning oil and/or an auxiliary surfactant, and prevents a decrease in viscosity over time, thereby improving product stability.

These thickeners are preferably contained in an amount of 0.1 to 20% by weight based on the total weight of the conditioning shampoo composition. When the content of the thickener is less than 0.1% by weight, the increasing effect is insufficient, and when the content of the thickener is more than 20% by weight, the viscosity is too high, which makes it difficult to use the product.

The shampoo composition of the present invention may also optionally further contain an ester-based or ether-based oil. The oil is used to facilitate combing by reducing the stiffness of the hair in wet and dry conditions, and to provide a conditioning effect to the hair. As the ester-based or ether-based oil, di polypropylene glycol-2 myristyl alcohol ether-10 adipate (Di PPG-2 Myreth-10 adipate), dicaprylyl ether (Dicaprylyl ether), diisopropyl adipate Pate (Diisopropyl adipate), ethylhexyl palmitate (Ethylhexyl palmitate) and the like may be used alone or in combination, and the use is not limited as long as it is an ether and ester-based conditioning oil that can be used in a conventional shampoo.

The conditioning oil is preferably contained in an amount of 0.05 to 5% by weight based on the total weight of the shampoo composition. When the content of the oil is less than 0.05% by weight, the conditioning effect may be insufficient, and when the content of the oil exceeds 5% by weight, the foaming force may be rapidly reduced.

The conditioning shampoo composition of the present invention may also include cationic polymers and anionic surfactants commonly used in conditioning shampoo compositions.

Examples of anionic surfactants included in the shampoo composition of the present invention include sodium lauryl sulfate, ammonium lauryl sulfate, sodium polyoxyethylene lauryl sulfate, ammonium polyoxyethylene lauryl sulfate, and mixtures thereof, but are not limited thereto. .

The anionic surfactant may be included in an amount of 1 to 30% by weight based on the total weight of the conditioning shampoo composition, and if the content is less than 1% by weight, the cleaning power decreases, and if it exceeds 30% by weight, the conditioning effect may be deteriorated.

As a cationic polymer included in the shampoo composition of the present invention, a reaction product of quaternary ammonium in which acrylamide and dimethyl diallyl ammonium chloride are polymerized, for example, polyquaternium-7, trimethylammonium-substituted epoxide and Reaction products of quaternary ammonium in which hydroxyethylcellulose is polymerized, for example, polyquaternium-10, guarhydroxypropyltrimonium chloride, such as Jaguar C17, mixtures thereof, etc. may be used, It is not limited thereto.

The cationic polymer may be contained in an amount of 0.01 to 1% by weight relative to the total weight of the conditioning shampoo composition, and if the content is less than 0.01% by weight, the conditioning effect may be insufficient, and if it exceeds 1% by weight, there is a concern that it may cause scalp irritation. have.

Therefore, the conditioning shampoo composition of the present invention may contain 0.1 to 20% by weight of an amino acid-based or carboxylate-based auxiliary surfactant alone or mixed with respect to the total weight of the composition; 0.1 to 20% by weight thickener; Optionally an ester-based or ether-based oil alone or mixed 0.05 to 5% by weight; 1 to 30% by weight of anionic surfactant; And 0.01 to 1.0% by weight of the cationic polymer.

The conditioning shampoo composition of the present invention may further include auxiliary ingredients commonly used in shampoos, such as fragrances, pigments, preservatives, and pH adjusters, in addition to the above ingredients within a range that does not impair the object of the present invention.
