Description

Body cleanser composition {BODY CLEANSE COMPOSITIOM}

[TECHNICAL FIELD OF THE INVENTION]

The present invention relates to a human cleansing composition, and more particularly, to a human cleansing composition having a feature of excellent moisturizing property, flexibility, phase stability, foaming force and usability and very low skin irritation.

[Private Technology]

Human cleanser has proper foaming power in cold water and hot water, removes oily and aqueous pollution adhered to skin, has less irritation on skin, prevents excessive degreasing, and supplies moisture to skin that is easy to be deprived during cleaning. A product that can prevent skin roughness and increase skin flexibility by excellent skin moisturizing power so as not to evaporate is preferable.

Typically, human cleansers include surfactants, detergents, moisturizers such as natural moisturizing ingredients and natural vegetable oils, active ingredients for pursuing functionality, and aromas with aroma effects. Suitable mixing of surfactants and other ingredients This product gives moisturizing, cleaning and foaming power to the product. Looking at the product characteristics according to the surfactant, the use of only the fatty acid soap component of the anionic surfactant has the advantage of excellent foaming power and cleansing power, but if the cleaning power is excessive, the skin may be weakened or roughened, whereas the interface except fatty acid soap component In the case of the active agent, the foaming force is appropriate, but the skin is left with a slippery feeling due to the lack of skin adsorption and rinsing of the surfactant, and sometimes there is a problem of causing skin irritation due to the surfactant.

In order to solve this problem, products have been developed to increase the content of the active ingredient to improve the moisturizing power and flexibility while at the same time minimizing the human irritation due to the adsorption of the surfactant. As part of this, the development of formulations using emulsification and solubilization techniques that can increase the content of natural moisturizing ingredients and copper and vegetable oils is being actively made. However, when the oil-containing moisturizing component is contained in a large amount, the rinsing property is lowered, and the oil and emulsifier components are defoamed, so that the foaming power is notably reduced, and the time-lapse stability such as the phase separation due to the excess oil component is not good. The problem remains a challenge to be solved.

In order to solve the above problems, an object of the present invention is to provide a skin hypoallergenic human cleansing composition excellent in moisturizing properties, flexibility, phase stability, foaming force and feeling.

In order to achieve the above object, the present invention comprises 1 to 45% by weight of monoglyceride sulfonate, 2 to 20% by weight of surfactant, 0.01 to 25% by weight of oil, 0.005 to 5% by weight of water-soluble polymer and the balance of water It provides a human cleanser composition.

Hereinafter, the present invention will be described in detail.

The inventors of the present invention, while researching to develop a human cleansing composition having excellent moisturizing ability, foaming ability and usability, almost no skin irritation, and having phase stability, the present invention has a certain ratio of monoglyceride sulfonate, surfactant, oil and water-soluble polymer. When used, it was confirmed that the above effects can be achieved, and based on this, the present invention was completed.

The present invention relates to a human cleansing composition comprising 1 to 45% by weight of monoglyceride sulfonate, 2 to 20% by weight of surfactant, 0.01 to 25% by weight of oil, 0.005 to 5% by weight of water soluble polymer and a balance of water.

The monoglyceride sulfonate may be prepared by using one or more kinds of fatty acids derived from animal oils such as tallow and lard and vegetable oils such as palm oil, palm oil and palm kernel oil.

(Formula 1)

In Formula 1, R is an alkyl group having 7 to 21 carbon atoms, M is sodium, potassium, triethanolamine or ammonia.

For example, the monoglyceride sulfonate may be prepared from palm oil containing at least 40 parts by weight of an alkyl group having 12 carbon atoms, palm kernel oil containing at least 40 parts by weight or more of an alkyl group having 12 carbon atoms, and fatty acids derived from lauric acid. Monoglyceride sulfonate is prepared by a conventional manufacturing method, for example, by reacting epichlorohydrin with a reducing agent such as sodium sulfate to prepare an intermediate sodium chloro hydroxy sulfonate salt, and then substituted esters using alkali salts of higher fatty acids. It can be prepared by the reaction. Monoglyceride sulfonates contain ester groups in one molecule, resulting in low skin irritation to the human body and low solubility compared to other surfactants. This may be due to the hydrogen bonding between the negative charge of the hydroxy group and the sulfonate.

Monoglyceride sulfonate may be included in the human cleanser composition in an amount of 1 to 45% by weight, but preferably 3 to 35% by weight. If the content is less than 1% by weight, the physical properties and stability of the formulation may not be good. If the content is more than 45% by weight, foaming, skin flexibility, and skin moisturizing ability are improved, but problems with physical properties and stability are caused by hardening. In addition, the product may not be good enough to reduce the quality of the product.

The surfactant of the present invention may be one or more selected from the group consisting of conventional anionic, nonionic, cationic and amphoteric surfactants. Examples of cationic surfactants include cetrimonium chloride, stearamidopropyldimethylamine, and disetyldimethylammonium chloride. Examples of anionic surfactants include sodium laureth sulfate, acyllauryl sulfate, and sodium coco. Monoisoethionate, disodium coco ampodiacetate, sodium lauryl sulfate, lauryl ammonium sulfate, polyoxyethylene lauryl sulfate and polyoxyethylene lauryl ammonium sulfate, and examples of nonionic surfactants include lauryl acid Diethanolamide, palm oil fatty acid diethanolamide, and palm oil fatty acid monoethanolamide, and examples of amphoteric surfactants include, but are not limited to, betaines, cocamidopropyl betaines, alkylglycinates and alkylaminopropionates It is not. The surfactant may be used in the human cleanser composition at 2 to 25% by weight, preferably 3 to 20% by weight. When the content of the surfactant is less than 2% by weight, the surface tension of the bubble is low, the bubble is difficult to form and the bubble is easily lost, so it is difficult to expect abundant bubble power, there is a disadvantage that the decontamination power is poor, exceeding 25% by weight If the foam is good but the rinsing ability is not good, there is a strong feeling of slippery skin, the overall use is not good.

The oil of the present invention is a conventional oil used for moisturizing purposes, and vegetable oil or liquid paraffin may be used. Examples of vegetable oils include, but are not limited to, soybean oil, macadamia oil, manuka oil, and sunflower oil. The oil is included in the human cleanser composition in an amount of 0.01 to 25% by weight, preferably 0.1 to 15% by weight. If the oil content is less than 0.01% by weight, the physical properties and stability of the product are improved, but the skin irritation, skin flexibility, and skin moisturizing power of the present invention are hardly effective, and when it exceeds 25% by weight, it shows an excellent moisturizing effect. It affects the physical properties and stability, and there is a tendency to significantly reduce the foaming force due to the defoaming action.

The water-soluble polymer of the present invention may be selected from the group consisting of carboxymethyl cellulose, styrene / acrylate copolymers, acrylate / alkylacrylate crosspolymers, and mixtures thereof, and preferably 0.001 to 5% by weight, preferably in the human cleanser composition. Is included in an amount of 0.01 to 3% by weight. Since water-soluble polymers are used for the purpose of increasing the usability, bubble stability and stability of the product, when the content thereof is less than 0.001% by weight, it is difficult to increase the physical properties and stability of the product, and when the content exceeds 5% by weight, a high viscosity gel phase is formed. Usability such as spreadability, spreadability is not good, there is a disadvantage that the skin becomes rough during drying after use.

In addition, the human body cleaner composition of the present invention may further include a substance commonly used in cosmetics or detergents, such as coloring agents, flavoring agents, fungicides, antioxidants and metal ion sequestrants in addition to the above-mentioned effective ingredient.

 Hereinafter, examples of the present invention will be described. The following examples are only for illustrating the present invention, but the protection scope of the present invention is not limited to the following examples.
