Description

[0001] The present invention relates to a calcined cosmetic composition comprising volatile oil as a solvent,

The present invention relates to a plasticized cosmetic composition comprising a volatile oil as a solvent and more particularly to a plasticized cosmetic composition comprising a volatile oil as a solvent and a plastic type cosmetic composition comprising an aluminum soap and a modified clay mineral .

Conventionally, a calcination type cosmetic composition which is formed by molding and drying a paste phase is formed by mixing a powder phase with an emulsion of an oil-in-water or water-in-oil type. However, these conventional methods are complicated due to the necessity of preparing an emulsion. Because of using water, there are restrictions on the coloring matters and the raw materials. Due to the problem of adjusting the pH depending on the problem and the problem of the emulsion stability in the bulk state There were difficulties in manufacturing.

A wet type cosmetic composition which contains a large amount of a volatile solvent and is formed by imparting flowability is generally subjected to suction molding by mixing a large amount of a volatile solvent in a powder composition containing or not containing an oil binder. However, this conventional method requires at least 50% of the solvent in comparison with the powder composition. In the suction molding, various components are lost together with the solvent, and some components such as pearl are poured into the suction part. . In particular, Korean Patent Publication No. 2012-0119330 discloses a wet molding cosmetic composition and a method for producing the same, which require a special equipment for removing a volatile solvent by 60% or more of the powder composition.

The cosmetic composition through the general production methods of the above two methods has been accompanied by problems such as dusting and lack of adhesion due to limitations in respective molding methods. Korean Patent No. 1439854 discloses a cosmetic composition and a method for producing a plasticized cosmetic composition having high skin adhesion and durability. In order to solve such drawbacks in feeling and difficulty in manufacturing in two ways, a volatile solvent dispersed in silicone- However, this volatile solvent has difficulties in using as well as equipment restrictions due to the use of isopropyl alcohol which is low in safety and heavy in use and handling as an alcohol system.

In addition, when a volatile solvent is used as the calcination type solvent, there arises a problem in the molding stability that the hardness becomes weak. In order to solve the above-mentioned problems, conventionally, modified clay minerals are contained. However, there is a limit to solving the above-mentioned problems by merely including the modified clay mineral in the calcined cosmetic composition containing a volatile solvent.

The inventors of the present invention have made intensive efforts to overcome the problems of the prior art. As a result, the inventors of the present invention have found that a calcined type cosmetic composition containing volatile oil as a solvent is characterized in that it comprises an aluminum soap and a modified clay mineral , It has been confirmed that the molded article is excellent in feeling and is also excellent in the hardness to ensure the molding stability and the stability of the product, thereby completing the present invention.

Accordingly, a main object of the present invention is to provide a plastic type cosmetic composition comprising aluminum soap not only excellent in usability but also excellent in hardness, molding stability and product stability.

According to one aspect of the present invention, there is provided a calcined cosmetic composition comprising a volatile oil as a solvent, wherein the calcined cosmetic composition comprises aluminum soap and modified clay mineral.

The term " calcined type " means a process of drying, and more particularly, a method of mixing a volatile solvent into a powder in a cosmetic composition and removing it through a drying process to complete a cosmetic composition. At this time, water or alcohol was used as a volatile solvent. However, in the present invention, volatile oil is used among non-volatile oils and hydrocarbon oils among volatile oils.

Conventionally, a powder phase is mixed with an emulsion of water-in-oil type or water-in-oil type to form a plastic type cosmetic. However, such a process is relatively complicated and has various manufacturing difficulties because it contains water as a solvent. In the case of plasticized cosmetics containing a volatile solvent as a solvent, since the volatile solvent is contained in an amount of 50% or more, there arises a problem of molding stability such that the hardness is weakened. In order to solve such a problem, There is a disadvantage that it occurs. In order to solve the above problems, the inventors of the present invention have found that a plasticized cosmetic composition using a volatile oil as a solvent contains 50% by weight or less of a volatile oil and the aluminum soap forms a gel at a specific temperature by an oil When the aluminum soap and modified clay minerals are contained by using the characteristics and the hardness formation property by the modified clay mineral, the molding stability such as reduction of the surface dye release, reduction of the drying time, stability of the anticorrosive and dropping stability can be ensured, It is possible to provide a superior plastic type cosmetic composition and complete the present invention.

The aluminum soap may be mixed first with the oil phase. However, if the gel is formed once by mixing the aluminum soap and the oil phase, the aluminum soap will not melt well. Further, since the high temperature process must be maintained continuously, So that a great deal of force is required for dispersion. Therefore, in the present invention, aluminum soap was linearly dispersed on a powder, and then mixed in an oil phase.

In the present invention, the aluminum soap may be a divalent or trivalent aluminum soap, and is preferably selected from the group consisting of Al-stearate, Al-palmitate, al-myristate, And at least one selected from the group consisting of al-laurate.

In the present invention, the modified clay minerals may include any modified clay minerals included in the conventional calcination type cosmetic composition. Preferably, the modified clay minerals include distearmonium hectorite, stearalkonium hectorite ), Quaternium-18 Hectorite, and Bentonite. ≪ Desc / Clms Page number 2 >

In the present invention, the calcined type cosmetic composition preferably comprises 40 to 75% by weight of powdery phase, 0.01 to 30% by weight of oil phase, 20 to 40% by weight of volatile solvent, 0.1 to 3.0 of aluminum soap and 0.1 to 3.0 of modified clay mineral By weight to 5.0% by weight. The ratio of powder phase, oil phase, and volatile solvent ultimately determines the flowability and aggregation of the whole bulk and determines the usability. Therefore, if the powder phase is too small, the extrusion process can not be performed because there is no lump, and if it is too much, the flowability becomes too high. Also, if the oil phase is too large, caking will occur when it is used, and if it is too small, it will not be used, and the powder will be blown out. The volatile solvent is limited to the amount of oil in accordance with the flow rate of the impregnation, so that the amount of the volatile solvent is limited. In the case of the aluminum soap, if it is less than 0.1% by weight, the formability is weakened, and the problem of stability of the formulation as well as the problems of dusting of the powder and the problem of flaking is problematic. When the content is more than 3% by weight, the feeling of use is caking (phenomenon in which the contents are not taken) A phenomenon may occur. In the case of the modified clay minerals, if it is less than 0.1% by weight, there is a problem of powderiness or lack of adhesion, and when it exceeds 5.0% by weight, the feeling of use is stiff and caking (phenomenon in which the contents are not taken) .

In the present invention, the powder phase may include all of the powders included in the calcination type cosmetic composition in the past, and preferably, talc, mica, synthetic mica, cericite, silica, titanium dioxide, silicone- Wherein the inorganic pigment is at least one selected from the group consisting of oxides, nylon powders, polymethacrylate powders, urethane powders, acrylate (co) polymers, polyethylene (co) polymers, organic dye pigments, inorganic dye pigments and pearl pigments. In addition, the powder phase may not be surface-treated, but may be surface-treated with silicone, metal salt, fatty acid, amino acid, lauroyl lysine or lecithin.

In the present invention, the oil phase may include all oils conventionally contained in the plastic type cosmetic composition, and preferably includes trihexylhexanone, diisostearylmaltite, triglyceride, dimethicone, phenyltrimethicone , Camphor wax, jojoba wax, olive oil, macadamia nut oil, sunflower oil, palm oil, palm oil, and camel vegetable liquid fats And the like.
