Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a process for producing a stick type solid cosmetic,

The present invention relates to a method of producing a stick type solid cosmetic composition, and more particularly, to a method of producing a stick type solid type cosmetic composition which does not use a makeup tool (puff, brush, etc.) And a method of producing a stick type solid cosmetic composition which can impart a close contact feeling and the like.

Cosmetic powders used by women for make-up and various make-up are generally two-way, compact, eye shadow and blusher. These cosmetic powders are mixed with a certain proportion of oil, packed in a bulk state of cosmetic powder into an inner container, and put into a separate case by putting a certain pressure into a compressed powder state.

These common face and body makeup products can be classified into press products and non-press products. The press and non-press products have the advantages and disadvantages, respectively. The press product has the merit of being easy to apply, but it has the disadvantage that it breaks after use and is easily contaminated. In addition, since a cosmetic tool is used, when the product is faced with a make-up tool or when a product buried in the make-up tool is applied to the face, dust is necessarily generated and there is a limitation in improving the adhesion. In the case of non-press products, there is an advantage in that the cosmetic can be freely made with a desired cosmetic tool, but there is a disadvantage in that dust or powder may leak during carrying.

Among conventional press-type toning cosmetics, lightly flaky products cause flaking, and good-eating products can cause problems such as caking.

There are various ways to manufacture stick-type cosmetics. The most common method is to use wax to make sticks in the same form as oil / powder / wax. Cosmetics manufactured by this method include lipstick, stick foundation, and ball touch (blusher). However, the sticks manufactured by this method have a rather oily and sticky feeling rather than a feeling of powderiness after application, which makes it difficult to apply them as a base product.

In addition, as a method of producing a compression type powder by a wet type, when a stick type powder is manufactured without extrusion of a separate extruder, a large amount of bubbles may be generated in the product, which may affect the stability of the product. In this case, the stick stability is deteriorated and it is easily broken, and even when used, it is not good for cosmetic due to a large air bubble inside the product. In addition, since the equipment for producing the compression-type powder is produced in a continuous phase, it is not suitable for the production of stick powder which requires the use of a separate extruder.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a method for manufacturing a stick type solid cosmetic composition, which comprises extruding a cosmetic dough.

The present invention also provides a method for manufacturing a cosmetic composition, which is free from dusting due to the use of a separate cosmetic tool and which is light and thin in terms of the characteristics of a baked formulation, To provide a stick-type solid cosmetic composition.

Particularly, the production method of the present invention includes a step of compacting a product in a kneaded state and a step of defoaming in an extrusion step, molding the product into a predetermined shape and drying the product, thereby preventing bubble formation inside the cosmetic, great.

The stick type solid cosmetic composition of the present invention comprises a step of preparing an emulsion containing a binder, water and an oil, preparing a powder part, preparing a dough by mixing the emulsion with the powder part, , Cutting the extruded extrudate, and drying the extruded cut.

The method for producing the stick type solid cosmetic composition of the present invention will be described in detail as follows.

(S1) Production of emulsion

This step is a step of producing an emulsion containing a binder, water and an oil.

The binder maintains an appropriate viscosity of the emulsion, and binds the powder to maintain the stability of the product.

The binder may be at least one selected from the group consisting of hydroxyethyl acrylate / sodium acryloyldimethyl taurate copolymer, starch, magnesium aluminum silicate, and the like. Can be used.

The binder is preferably included in an amount of 0.1 to 10 wt%, more preferably 2 to 5 wt%, based on the total weight of the emulsion. When the content is less than 0.1% by weight, penetration hardness of the product after drying is too low to be stable. If the content exceeds 10% by weight, penetration hardness of the product after drying is too high, It is difficult to use because it is not -off.

The kind of the water or the oil is not particularly limited, and a conventional one used for a cosmetic composition can be used. After using these water, all should be removed by drying, and the finished product should be free of water. Such water or oil may be neutral or have color.

The oil refers to a hydrophobic liquid substance having a viscosity at room temperature and provides a bonding force between the powder particles and provides a smooth feeling when applied to the skin to provide a uniform coating on the face. The oils may be synthetic oils, vegetable oils, animal oils and mineral oils commonly used in cosmetic compositions.

More specifically, the oil may be a hydrocarbon-based oil such as squalane or mineral oil; Caprylic / capric triglyceride, neopentyl glycol dicaprate, 2-octyldodecyl myristate, isopropyl myristate, isocetyl ethyl hexanoate, pentaerythritol tetraethyl hexanoate, butylene glycol dicapryl Ester-based oils such as lactate caprate, hexyl laurate, distearyl malate, cetyl 2-ethylhexanoate, octyldodecanol, and glyceryl triethylhexanoate; Vegetable oils such as olive oil, avocado oil, jojoba oil, and macadamia oil; Animal oils such as lanolin; And silicone oils such as dimethylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, methyltrimethicone, phenyltrimethicone, cyclomethicone, dimethicone, and the like.

Specifically, the emulsion is prepared by emulsifying an emulsion using a homomixer by adding an oil phase mixed with a surfactant and an oil to an aqueous phase in which water and a binder are dispersed at 80 DEG C, cooling the emulsion to 55 DEG C, The final emulsion can be prepared. If necessary, the emulsion can be defoamed and cooled.

The kind of the surfactant is not particularly limited, and a conventional surfactant used in a cosmetic composition may be used. Specifically, sorbitan fatty acid esters such as sorbitan trioleate, sorbitan sesquioleate, sorbitan sesquistearate, sorbitan monostearate, sorbitan monolaurate, sorbitan monopalmitate and polysorbate 60 , Glycerin fatty acid esters such as glycerin monostearate and glycerin monooleate, polyglycerin fatty acids such as diglycerin diolate, diglycerin monooleate, diglycerin monostearate, tetraglycerin monooleate, and tetraglycerin monostearate Esters, pentaerythritol monostearate and pentaerythritol mono palmitate, propylene glycol fatty acid esters such as propylene glycol monostearate and propylene glycol monolaurate, diethylene glycol monostearate, diethylene glycol monostearate, diethylene glycol monostearate, Gly Diethylene glycol fatty acid ester such as monolaurate, polysaccharide fatty acid ester such as sucrose tristearate, sucrose palmitate, sucrose distearate and the like, and tetiltriminobromide may be used have.

(S2) Powder preparation

This step is a step of preparing a powder part, and the powder part may include a pigment or a diluent.

The pigment may be a conventional natural pigment, a synthetic pigment, a pearl pigment, or the like used for the production of cosmetics.

The diluent may be at least one selected from the group consisting of mica, talc, kaolin, nylon, silicone powder, bismuth oxychloride, sericite and silica.

In addition to the pigment and the diluent, the powder part may further include titanium oxide to impart a covering force to the color cosmetic composition, and starch and / or magnesium aluminum silicate, which is a binder, may further be included in the powder part.

If necessary, titanium oxide, starch and / or magnesium aluminum silicate may be mixed and pulverized to prepare a powder part. The reason for adding starch and magnesium aluminum silicate together is that when the organic binder (hydroxyethyl acrylate / sodium acryloyldimethyltaurate copolymer) forms cross-linking on the surface of the product after drying, And magnesium aluminum silicate make the net surface of the product more flexible.

(S3) Mixture of emulsion and powder mixture

This step is a step of preparing a dough by mixing the emulsion and the powder part.

The emulsions and powders may be mixed using a high viscosity mixer.

It is preferable that the emulsified material and the powder part mix the emulsion at 35 to 50% by weight and the powder part at 65 to 50% by weight based on the total weight of the color cosmetics.

If the content of the emulsion is less than 35% by weight, the hardness of the slurry may be too high to fill. If the content of the emulsion is more than 50% by weight, the hardness of the slurry may be too low.

The emulsion and the powder part may be mixed as described above to prepare a batter, followed by defoaming if necessary. The defoaming can be carried out according to a conventional method used in the art.

(S4) Extrusion and defoaming

This step is a step of extruding the prepared dough.

The extruder may be a piston type or screw type extruder commonly used in the art, and may be a vacuum device capable of performing a defoaming function. The extruder may be equipped with a cutter, .

In the conventional method of producing a baked powder product, a cosmetic can be produced only by a defoaming process by extrusion of a piston using a general piston type filling machine. If the extrusion is performed as described above, the dough may be extruded in various shapes according to a die used in the extruder.

On the other hand, the present invention includes a process of mixing slurry with a piston during the extrusion step and a process of defoaming with a vacuum device. This prevents bubbles from being generated inside the product, thereby lowering the stability and the beauty. Further, the extruded extrudate may further be molded into a mold as required.

(S5) Cutting

The extruded kneaded product may be cut into a predetermined length by a cutter attached to the extruder.

(S6) Drying

This step is a step of drying the cut extrudate. The drying is carried out to vaporize the solvent present in the extrudate. The drying may be carried out according to a conventional drying method, for example, a dryer, vacuum drying, fluidized drying and the like. If the drying is performed at a low temperature in the drying, a long drying time is required. If the drying is performed at a high temperature, the drying time may be shortened. In particular, it is preferred that the drying is to slowly vaporize the solvent at a low temperature to minimize deformation of the final product.

Specifically, the drying is preferably carried out at a temperature of 30 to 80 ° C, preferably about 50 ° C for a suitable time so that the total residual humidity contained in the final cosmetic is 5% or less. If the total residual humidity contained in the final cosmetic exceeds 5%, microorganisms may be found and the usability may be deteriorated. The residual humidity can be measured by leaving the sample at 105 DEG C for 2 hours, and then comparing the difference in weight before and after the sample is left standing. Residual humidity (%) = (A-B) / A X 100 (A: weight before leaving at 105 ° C, B: weight after leaving at 105 ° C for 2 hours)

The color cosmetic composition of the present invention may be further polished if necessary. At this time, the surface of the cosmetic may be polished using a trimer.

The color cosmetics of the present invention produced by the above-mentioned method can be manufactured with a stick having a length of 1 mm to 100 mm and a thickness of 1 mm to 100 mm.

The color cosmetic composition of the present invention as described above is not a general press type but a dried (baked) product in a dryer, and contains a fine air layer in the product, so that it is light and thin and has a good close adhesion property to the skin.

The color cosmetic composition according to the present invention includes a step of extruding through an extruder, so that it has less flaking phenomenon than a conventional cosmetic composition produced by the wet production method, has a light and thin, excellent barrier effect on cosmetic appearance, can do.

Particularly, it is possible to prevent the bubbles from being generated in the product, including the step of squeezing the kneaded product in the extrusion step and the step of defoaming, thereby preventing the stability and the beauty of the product from being hindered.
