Description

Technical Field [0001] The present invention relates to an OW solid cosmetic composition,

The present invention relates to an OW solid cosmetic composition and a process for producing the same.

Emulsion type make-up cosmetics can be divided into O / W and oin in water and W / O and water in oil. The oil-in-water type make-up cosmetics conventionally available on the market are excellent in oil resistance due to sebum and water resistance due to perspiration. However, there is a limitation in that it imparts a feeling of skin burden due to stickiness, oiliness, etc., and deteriorates the spreadability and spreadability.

On the other hand, the underwater type emulsion makeup cosmetic material is light and moist feeling, but has a drawback such as discoloration of sebum due to poor water resistance and makeup persistence due to the injury.

One aspect of the present invention is to provide a hydrogel-type OW solid cosmetic composition which is capable of imparting sufficient moisture and a water-soluble skin active ingredient to the skin unlike the WO formulation, which has been conventionally marketed, and has improved emulsion stability, and a process for producing the same .

The present invention provides an OW solid cosmetic composition comprising 0.1 to 5 parts by weight of a gelled polymer, 1 to 40 parts by weight of an oil, and the balance water, based on 100 parts by weight of the whole composition.

The OW solid cosmetic composition may further comprise 5 to 40 parts by weight of an inorganic powder and 0.1 to 30 parts by weight of an oil-absorbing powder based on 100 parts by weight of the total composition.

The inorganic powder may include an ultraviolet screening agent, a pigment, or a mixture thereof.

The OW solid cosmetic composition may further comprise at least one member selected from the group consisting of a surfactant, a skin active ingredient, a sequestering agent for metal ions, a moisturizing agent, a preservative, a fragrance and an enhancer.

The OW solid cosmetic composition may be in the form of a hydrogel.

The hardness of the OW solid cosmetic composition may be 0.5 to 50N.

The temperature of the OW solid cosmetic composition may be 0 to 50 캜.

The pH of the OW solid cosmetic composition may be 4 to 8.

The present invention also provides: 1) an aqueous phase preparation step of adding a gelling polymer and other water-soluble components to purified water and then heating to a temperature of 60 to 80 캜 to prepare a water phase; 2) an oil phase manufacturing step of mixing an oil and, if necessary, an inorganic powder, an oil absorbing powder, and a surfactant, and then heating the mixture at a temperature of 60 to 80 캜 to produce an oil phase; 3) a step of preparing a mixture by dropping the oil phase on the water and mixing the mixture; And 4) filling the mixture in a container and then cooling the mixture.

By using the OW solid cosmetic composition of the present invention and the manufacturing method thereof, it is possible to obtain a hydrogel type OW solid cosmetic which can effectively transmit moisture to the skin and the water soluble skin effective ingredient, and has improved emulsion stability.

Hereinafter, preferred embodiments of the present invention will be described. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. Further, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art.

An OW solid cosmetic composition is provided according to the present invention. The cosmetic composition of the present invention may contain 0.1 to 5 parts by weight of a gelling polymer, 1 to 40 parts by weight of an oil and the balance water, based on 100 parts by weight of the total composition.

The OW solid cosmetic composition may further comprise 5 to 40 parts by weight of an inorganic powder and 0.1 to 30 parts by weight of an oil-absorbing powder based on 100 parts by weight of the total composition.

The gelled polymer may be contained in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of the total composition. When the gelated polymer is contained in an amount of less than 0.1 part by weight based on the total weight of the composition, gelation does not occur and a solid cosmetic composition can not be produced. When the gelated polymer is contained in an amount exceeding 5 parts by weight, the feeling of use is deteriorated.

The oil may be selected from the group consisting of isopropyl myristate, ethyl laurate, ethyl myristate, isopropyl palmitate, butyl laurate, hexyl laurate, caprylic / capric triglyceride, butyleneglycol dicaprylate / Ester oils such as propyl myristate, triethylhexanone, cetylethylhexanoate, octyldodecanol, and polyol esters; Hydrocarbon oils such as cyclododecane, isooctane, liquid paraffin, vaseline, hydrogenated polydecene, cyclooctane, cyclopentane and squalane; Waxes such as microcrystalline wax, beeswax, lanolin wax, ozokerite wax, candelilla wax, carnauba wax and synthetic wax; Jojoba Oil, Avocado Oil, Almond Oil, Olive Oil, Sesame Oil, Wheat Germ Oil, Four Flower Oil, Camellia Oil, Castor Oil, Grape Seed Oil, Green Tea Seed Oil, Macadamia Nut Oil, Palm Oil, Rosehip Oil, Natural oils such as wood oil, argan tree kernel oil and lavender oil; And silicone oils such as cyclomethicone, phenyltrimethicone, cyclopentasiloxane, dimethicone, and the like.

The oil may be added in an amount of 1 to 40 parts by weight based on 100 parts by weight of the total composition. When the oil is contained in an amount of less than 1 part by weight, the oil content is low and the oil is not emulsified. When the oil is contained in an amount exceeding 40 parts by weight, the emulsion stability is deteriorated.

The inorganic powder may include an ultraviolet screening agent and a pigment. The ultraviolet screening agent includes an inorganic ultraviolet screening agent and an organic ultraviolet screening agent.

At this time, in the case of the inorganic sunscreen agent, the larger the average particle size, the more the whitening phenomenon is applied to the skin, thereby decreasing the value as a product. On the other hand, if the particle size is too small, the skin may penetrate and cause irritation. The average particle size is preferably 500 nm or less, and 10 to 50 nm is preferable when skin irritation and cloudiness are simultaneously considered.

The inorganic powder may be included in an amount of 5 to 40 parts by weight based on 100 parts by weight of the total composition.
