Accordingly, an object of the present invention is to provide a cream type cleansing cosmetic composition comprising an oily portion of 1 to 20% by weight based on the total weight of the composition.

Another object of the present invention is to provide a method for producing a cosmetic composition for cream type cleansing.

The present inventors have made intensive research efforts to develop a cosmetic composition for cleansing that contains a high content of oil and has the stability of the formulation. As a result, when mixing oil, (fat) alcohol and polymer in a specific content ratio, a cream-type cosmetic composition that contains a large amount of oil and secures the stability of the formulation and maintains excellent detergency and moisturizing power is produced. It was found that it can be obtained.

The present invention relates to a cream-type cleansing cosmetic composition containing a large amount of oil and a method for producing the same.

Hereinafter, the present invention will be described in more detail.

One aspect of the present invention relates to a cream type cleansing cosmetic composition comprising an oily portion of 1 to 20% by weight based on the total weight of the composition.

The oil phase may include oil, fatty alcohol, and butter.

The oil phase part is camellia oil, sunflower seed oil, Brazil nut seed oil, sweet almond oil, olive oil, grape seed oil, cotton seed oil, apple seed oil, corn oil, coconut palm oil, safflower seed oil, cetyl ethylhexanoate, Ethylhexyl stearate, caprylic capric triglyceride, stearyl alcohol, cetearyl alcohol, shea butter, mango seed butter and/or cacao seed butter, but are not limited thereto.

The oil phase may be included in an amount of 1% to 20% by weight based on the total weight of the cosmetic composition. When the oily part is included in an amount of less than 1% by weight, not only the cream-type formulation is not implemented, but also there is a problem that the cleaning power of makeup is remarkably deteriorated. In addition, when the oil phase portion is included in an amount of more than 20% by weight, the oil phase does not stably exist and precipitates, or when excessive oil phase is included, there is a problem that the skin is dried after washing due to excessive removal of sebum during washing.

The cosmetic composition may further include a surfactant and a thickener.

The surfactant may be a surfactant derived from nature, for example sodium laureth sulfate, cocobetaine, cocamidopropylbetaine, lauramidopropylbetaine, disodium cocoamphodiacetate, laurylhydroxysulfatein, Potassium cocoate, potassium olivate, lauryl glucoside, decyl glucoside, coco glucoside, potassium cocoyl glycinate, ammonium lauryl sulfate, sodium lauryl sulfate, ammonium laureth sulfate and/or disodium laureth sulfosuccinate May be, but is not limited thereto.

The surfactant may be included in 10% to 60% by weight based on the total weight of the cosmetic composition. When the surfactant is included in an amount of less than 10% by weight, there is a problem that the cleaning power is significantly reduced. In addition, when the surfactant is included in an amount of more than 60% by weight, there is a problem that the skin becomes very dry due to excessive washing of the skin.

The thickener is acrylate/C10-30 alkyl acrylate crosspolymer, potassium hydroxide, carbomer, xanthan gum, acrylate copolymer, acrylate steareth-20 methacrylate copolymer, ammonium acryloyl dimethyl tau It may be a late behenes-25 methacrylate crosspolymer, sodium hydroxide, triethanolamine, tromethamine and/or arginine, but is not limited thereto.

The thickener may be included in an amount of 0.1% to 10% by weight based on the total weight of the cosmetic composition. When the thickener is contained in an amount of less than 0.1% by weight, a two-layered composition in which the oil phase and the aqueous phase are separated is obtained, or there is a problem that the oil is cut out of the formulation, and thus a stable cream-type formulation is not obtained. In addition, when the thickener is included in an amount of more than 60% by weight, it is out of the range of the content that can be dispersed in the formulation (supersaturated), so that the thickener is lumped or the powder does not dissolve and is present as it is.

The cosmetic composition may further include purified water, a moisturizing agent, a pH adjusting agent, a preservative, and the like in addition to the above-described components.

The moisturizing agent may be, for example, sorbitol, glycerin, 1,3-butylene glycol, propylene glycol and/or propylene glycol, which may be included in the cosmetic composition in an amount of 10% to 60% by weight based on the total weight of the composition. .

The cosmetic composition may include a cosmetically effective amount thereof and/or a cosmetically acceptable carrier, but is not limited thereto.

As used herein, the term "cosmetically effective amount" means an amount sufficient to achieve the efficacy of the composition of the present invention described above.

The cosmetic composition may be prepared in any formulation conventionally prepared in the art.

Ingredients included in the cosmetic composition of the present invention include ingredients commonly used in cosmetic compositions in addition to the active ingredient and carrier ingredient, for example, conventional auxiliary agents such as antioxidants, stabilizers, solubilizers, vitamins and fragrances. Can include.

Another aspect of the present invention relates to a method for preparing a cream-type cleansing cosmetic composition comprising the step of mixing an oily part, a surfactant, and a thickener at 60 to 80°C.

The oily portion may be included in an amount of 1 to 20% by weight based on the total weight of the composition.

The mixing may be performed using a mixer such as a homo mixer commonly used in the art.

The time and speed (rpm) in the mixing may vary depending on the ambient temperature of the workplace and the capacity of the mixer, and such mixing may be appropriately performed empirically to those skilled in the art or according to the instructions of the manufacturer of the mixer.

In the method of manufacturing the cream-type cleansing cosmetic composition, overlapping contents of the cream-type cleansing cosmetic composition are omitted in consideration of the complexity of the present specification.

The present invention relates to a cream-type cleansing cosmetic composition containing a large amount of oily phase and a method for manufacturing the same, wherein the cosmetic composition of the present invention not only secures the stability of the formulation while including a large amount of oily part, but also provides excellent cleaning power and moisturizing power. By doing so, it can be usefully used for cleansing cream-type makeup.
