Description

The present invention is easy to prepare, transparent, excellent in usability, stability over time to provide a good transparency solid perfume.

Conventional fragrance cosmetics are compositions such as honey beeswax and jojoba oil, and fragrances are added. These are opaque and poor in appearance, and have the problem of discoloration and separation over time. . In addition, various gelling agents are used to solidify the fragrance cosmetic, but there is a problem that it is difficult to dissolve due to poor dispersibility during preparation.

As a technique for providing a cosmetic material having transparency and excellent usability, a technique of blending a dextrin fatty acid ester and a heavy liquid isoparaffin (see, for example, Patent Document 1) an α-olefin oligomer and a dextrin fatty acid ester and / or 12 -There exists the technique (for example, refer patent document 2) which mix | blends hydroxy stearic acid. In addition, as a technique for providing a cosmetic having excellent moldability, transparency, and usability, a technique in which 12-hydroxystearic acid and dextrin fatty acid ester are blended (for example, see Patent Document 3), dextrin fatty acid ester and polyoxy A technique characterized by blending ethylene beeswax and a liquid oil component (see, for example, Patent Document 4), at least N-acyl-L-acidic amino acid dialkylamides such as N-2-ethylhexanoyl-L-glutamic acid dibutylamide There is a technique for solidification using a gelling agent of an oily base material containing one kind and at least one kind of monovalent lower alcohol such as 3-methoxy-3-methylbutanol (see, for example, Patent Document 5).

However, in Patent Document 1, although a transparent cosmetic is obtained, the dextrin fatty acid ester, which is a gelling agent for an oily base material, is difficult to disperse and dissolve in heavy liquid isoparaffin, which is a liquid oil, and the workability is poor. There is a problem that even if it is dissolved, the foam does not escape easily due to its high viscosity, and the finished cosmetic product has a problem that the foam contains and the appearance is deteriorated. Even in Patent Document 2, the viscosity is increased depending on the α-olefin oligomer selected as in Patent Document 1, and the dextrin fatty acid ester, which is a gelling agent for an oily base material, is difficult to disperse. In combination, there was a problem that the obtained cosmetic was inferior in transparency. With the technique of Patent Document 3, a transparent cosmetic product having excellent moldability can be obtained, but there is a problem in that a uniform coating film cannot be obtained when the cosmetic is applied and the usability is poor. On the other hand, although the technique of Patent Document 4 is excellent in transparency, moldability, and usability, since polyoxyethylene beeswax is used as a blending component, sufficient transparency cannot be obtained. With the technology of Patent Document 5, cosmetics excellent in transparency, moldability, and fragrance sustainability can be obtained, but the melting temperature of the oily gelled base material is 95 ° C or higher, and depending on the selection of the ingredients, it can be heated to 120 ° C. There is a problem that it is required and the workability is poor and the preparation method is not easy. In addition, when a fragrance containing a glycerin, ethanol, ethylene glycol or water and a surfactant are blended, there is a problem that even if the emulsion is not uniformly dispersed or even if the emulsified particles are uniformly dispersed, the entire cosmetic product is not transparent. there were. Because of the above problems, Patent Documents 1 to 5 do not describe a technique combining a fragrance and a surfactant.
Therefore, the preparation method is easy, and fragrances containing various fragrance ingredients and solvents with a wide range of HLB can be blended. The resulting cosmetics are excellent in transparency, stability, feeling of use, and fragrance sustainability. Solid transparent aroma cosmetics have been desired.

Under such circumstances, the present inventors have intensively studied to solve the above problems, and as a result, have found that the above problems can be solved by the present invention.
The present invention is one or more selected from dextrin myristate , mineral oil having a kinematic viscosity of 4.3 to 67.90 mm ² / s at 40 ° C., polyoxyethylene polyoxypropylene alkyl ether, and fatty acid polyoxyethylene sorbitan. A transparent kneaded perfume comprising 5.4 to 20% by weight of a perfume.

According to the present invention, the preparation method is easy, and various fragrance components and various fragrances containing solvents having a wide range of HLB can be blended, and the obtained cosmetics have transparency, stability, feeling of use, and sustained fragrance.

In the present invention, in addition to dextrin myristate (as a commercially available product, Leopard MKL2 (manufactured by Chiba Flour Mills) can be used), it is oil-soluble and has 8 to 24 (preferably 14 to 18) carbon atoms. An ester compound of a linear saturated or unsaturated fatty acid and dextrin can be added . Specifically, Pas palmitic acid dextrin, dextrin stearate. One or more of these can be used as required. Examples of commercially available products, Les opal KL2, Rheopearl TL2 (none, Chiba Flour Milling Co., Ltd.) can be used.
Although the compounding quantity of the component dextrin fatty acid ester used for this invention is not specifically limited, 5 to 40% is preferable with respect to the total amount of all the components. If the blending amount is less than this range, the transparent kneaded perfume becomes too soft, and if it is more, it is too hard and the usability is poor.

The component liquid oil used in the present invention is a mineral oil having a kinematic viscosity at 40 ° C. of 4.3 to 67.90 mm ² / s (preferably 12.30 to 67.90). Moresco white (manufactured by Matsumura Oil Co., Ltd.) can be used as a commercial product. Although the compounding quantity of the mineral oil used for this invention is not limited, 20 to 93% is preferable with respect to the total amount of all the components. Although it can be combined with other liquid oils, among the dextrin fatty acid esters that are blended components, dextrin myristate (trade name Leopard MKL2) and dextrin palmitate (trade name Leopard KL2) are soluble and transparent. In terms of compatibility with liquid paraffin, it is preferable to blend mainly.

In the present invention, nonionic surfactants are particularly effective, and those having an HLB of 9 to 17 are suitable. Commercially available products include polyoxyethylene polyoxypropylene alkyl ethers (PBC-34 (HLB16.5) and PBC-44 (HLB12.5) manufactured by Nippon Surfactant Kogyo Co., Ltd.), fatty acid polyoxyethylene sorbitan (manufactured by Wako Pure Chemical Industries, Ltd.) Tween 80 (HLB15)). In addition to the surfactant, the present invention includes polyoxyethylene hydrogenated castor oil (HCO-20 (HLB10) and HCO-60 (HLB15) manufactured by Nippon Surfactant Kogyo Co., Ltd.) and cations usually used in cosmetics. , Anionic, amphoteric, nonionic, amino acid surfactants can be used, such as metal soap, polyoxyalkylene alkyl ether, polyoxyethylene castor oil, mono fatty acid sorbitan, mono fatty acid polyoxyethylene sorbitan Alkyl glycoside, fatty acid polyethylene glycol, fatty acid glycerin, sodium acylglutamate, sucrose fatty acid ester can be used.
Although the compounding quantity of surfactant used for this invention is not specifically limited, 1-20% is preferable with respect to the total amount of all the components.
