Description

[0001] The present invention relates to an oily cleansing cosmetic composition,

The present invention relates to a cosmetic composition for oily cleansing which is improved in massage feeling and spreadability and reduced in oiliness after water cleansing through the combination of a nonionic surfactant and an ionic surfactant.

Cleansing cosmetics for cleansing the dirt and make-up of the skin include cream, oil, gel, oily, and liquid, and emulsion, oily, and aqueous type according to the formulation classification.

In the case of the aqueous type, a cleansing effect is imparted by mixing a small amount of oil with an ionic and nonionic surfactant in a base using water and a polyol. However, it has a disadvantage in that the feeling of use is neat, but the makeup removing power is low .

Cleansing oil, which represents oil-based type, does not contain a water-based oil and uses 100% oil. It has an excellent cleansing effect because it has excellent solubility with makeup and dirt adhered to skin from the outside. However, since it is easy to flow because it is low viscosity oil, it is inconvenient to use and it is difficult to diversify feeling of use, and if oil remains on the skin after use, the washability is deteriorated.

With the recent development of make-up products with superior sustainability, the market for oil-type products with the most excellent cleansing effect is increasingly increasing in the market, and the value in the cleansing market is increasing. Therefore, there are some products that improve various disadvantages such as being able to use in a wet hand including a certain amount of water, or to prevent easy flow by using an oil viscosity controlling agent. However, in terms of residual after water washing, there was no significant improvement in the type and ratio of nonionic surfactants.

Accordingly, it is an object of the present invention to provide an oily cleansing cosmetic composition which is improved in ease of application, feeling of massage and remnant feeling after cleansing, while forming a clear or translucent liquid or gel-like cleansing composition having excellent makeup removing power and water resistance The purpose.

In order to achieve the above object, the present invention provides a cosmetic composition for oily cleansing, which comprises a nonionic surfactant, an ionic surfactant, an oily component and an aqueous phase component.

The cosmetic composition for oily cleansing according to the present invention has excellent cleansing power and water resistance and at the same time greatly improves the existing problems of washability of existing oily cleansing products by using an appropriate combination and ratio of nonionic surfactant and anionic surfactant At the same time, the feeling of massage and applicability were improved.

The cosmetic composition for cleansing of the present invention includes a nonionic surfactant, an ionic surfactant, an oil component and an aqueous component.

The nonionic surfactant used in the present invention may be a hydrocarbon group or hydrocarbon silicone having a carbon number of 10 to 54 as a hydrophobic group, and the hydrocarbon group or the hydrocarbon group of the hydrocarbon silicone includes a linear or branched type, More specifically, alkyl or dimethyl silicone can be used. As the hydrophilic group, a polyglyceryl series, a polyethylene glycol series, a glucoside series, or the like can be used. In the present invention, a polyethylene glycol type such as glucoside type such as lauryl glucoside and decyl glucoside, PEG-20 glyceryl triisostearate and PEG-15 glyceryl isostearate, polyglyceryl-3 Polyglyceryl type nonionic surfactants such as diisostearate and polyglyceryl-10 diallylate were used.

The nonionic surfactant is contained in an amount of 5 to 50% by weight based on the total weight of the composition. If it is contained in an amount of less than 5% by weight, the washability deteriorates. If it is added in an amount of more than 50% by weight, it causes disadvantages such as induction of skin dryness and increase of the unit price.

The ionic surfactant used in the present invention is an anionic surfactant and the type of the anionic surfactant is not strictly limited. However, considering the compatibility with the oil used, the skin stability of the cosmetic and the skin irritation after use For minimization, an amino acid or phosphoric anionic surfactant is used. As the amino acid anionic surfactant, methyl caproyl taurate and potassium cocoyl glycinate may be used. As the phosphate anionic surfactant, sodium laureth-1 phosphate and the like may be used. However, the above-mentioned materials are merely examples and the present invention is not limited thereto.

The anionic surfactant is contained in an amount of 0.01 to 5% by weight based on the total weight of the composition in consideration of skin irritation and formulation safety, and the rinsability of the water is particularly improved when the anionic surfactant is contained in the above range. Since the rinseability is greatly improved by the mixing anionic surfactant, the kind of the nonionic surfactant to be used can be diversified and the use amount can be reduced.

The oily component to be used in the present invention is not particularly limited as long as it is generally used in cosmetics, and one or more oily components can be selected in consideration of makeup removing power and stability, and preferable examples thereof include hydrocarbons, esters, triglycerides, vegetable oils, May be used. In order to produce a transparent formulation, hydrocarbon oil is particularly effective and refracts when it passes through the interface between two kinds of mediums having a refractive index (light refractive index, isotropic) of an oily component. In this case, (The law of refraction) which is established between the refraction angle and the refraction angle, the transparency can be matched if the value of the constant is made the same.

The oil component is contained in an amount of 20 to 90% by weight, preferably 30 to 70% by weight based on the total weight of the composition. When silicone oil such as dimethicone or cyclomethicone is mixed with the oil component in an amount of 10 to 30% by weight based on the total weight of the composition in consideration of washability and formulation stability, mixing of lipstick, eye makeup product and cosmetic composition for cleansing It becomes easy and can be easily removed.

The water component used in the present invention is preferably contained in an amount of 3 to 50% by weight, more preferably 3 to 30% by weight, based on the total weight of the composition. The aqueous phase may contain, in addition to water, a polyhydric alcohol such as glycerin, 1,3-butylene glycol, dipropylene glycol, propylene glycol, hexylene glycol or the like or a component modified by adding a hydrophobic group to the polyol in an amount of 5 to 40% . When the water phase is contained in an amount of more than 50% by weight based on the total weight of the composition, it may affect the stability of the formulation, so that the content of the water phase should not exceed 50% by weight. In addition, formulations can be made without including water phase, but viscosity is too low, so it is easy to flow down upon application, so the usability is lowered.

The formulations prepared in the present invention are aqueous phase-containing oil formulations, which means a single-phase formulation that appears to be transparent or translucent in appearance, and can be a gel or a liquid type depending on the content and composition ratio of the surfactant and oil phase.

Hereinafter, the present invention will be described in more detail with reference to examples and test examples. However, the scope of the present invention is not limited to these examples. The compounding amount represents weight%.
