BACKGROUND OF THE INVENTION
[0002]
The present invention relates to an oily cosmetic material with significantly improved appearance gloss, reduced sweating over time, and improved stability. More specifically, a solid oily cosmetic blended with an organically modified clay mineral and a dicarboxylic acid condensate of diglyceryl branched chain fatty acid ester or a gel containing a nonionic surfactant having an HLB value of 4 to 12. The present invention relates to a method for suppressing perspiration .
[Prior art]
[0003]
Oily cosmetics prepared by solidifying oily components with waxes or gelled with an oil-gelling agent such as organically modified clay minerals or 12-hydroxystearic acid have good adhesiveness and elongation to the skin and make up the makeup. Since it is hard to resist and has an emollient effect, it is provided as a makeup cosmetic such as an oily foundation, oily blusher, oily eye color, and oily lipstick.
[0004]
In such oily cosmetics, in order to improve the emollient effect and improve the dispersibility of the powder, especially in the case of makeup cosmetics, a large amount of natural oily raw materials and ester oils having a certain degree of polarity are contained. However, the oily raw material having such polarity absorbs moisture over time, and a so-called sweating phenomenon in which a liquid oozes out on the surface of the oily cosmetic material often impairs the product value.
[Problems to be solved by the invention]
[0005]
Therefore, an object of the present invention is to obtain an oily cosmetic material that suppresses the above-described sweating phenomenon and has good stability over time. Furthermore, it was decided to improve the appearance of cosmetics.
[Means for Solving the Problems]
[0006]
As a result of various studies to solve the above problems, one or more organically modified clay minerals, one or more selected from dicarboxylic acid condensates of diglyceryl branched chain fatty acid esters, and an HLB value By blending an oily cosmetic with a gel containing one or more of 4 to 12 nonionic surfactants, the sweating phenomenon is well suppressed and the stability over time is improved. It has been found that the gloss of the appearance is remarkably improved, and the present invention has been completed.
DETAILED DESCRIPTION OF THE INVENTION
[0007]
In the present invention, the organically modified clay mineral constituting the gel blended in the oily cosmetic composition includes montmorillonite group clay minerals such as montmorillonite, beidellite, nontronite, saponite and hectorite, clay minerals such as vermiculite and bentonite, and alkyltrimethyl chloride. Those treated with a quaternary ammonium compound such as ammonium, dialkyldimethylammonium chloride and benzalkonium chloride can be used. Commercially available products such as dimethyl distearyl ammonium hectorite, dimethyl distearyl ammonium bentonite, and benzyl dimethyl stearyl ammonium hectorite can be used, and one or more of them are selected and used. The blending amount in the total amount of the oily cosmetic is suitably about 0.2 to 2.0% by weight.
[0008]
Further, in the present invention, the dicarboxylic acid condensate of diglyceryl branched chain fatty acid ester constituting the gel blended in the oily cosmetic together with the organically modified clay mineral is an ester of diglycerin obtained by dehydrating glycerin and a fatty acid having a branched chain. A monocarboxylic acid having 16 to 18 carbon atoms is used as the fatty acid having a branched chain, and a dicarboxylic acid having 6 to 10 carbon atoms is preferable. As such, diglyceryl isopalmitate adipic acid condensate, diglyceryl isopalmitate pimelic acid condensate, diglyceryl isopalmitate suberic acid condensate, diglyceryl isopalmitate azelaic acid condensate, di Glyceryl isopalmitic acid ester sebacic acid condensate, diglyceryl isostearic acid ester adipic acid condensate, diglyceryl isostearic acid ester pimelic acid condensate, diglyceryl isostearic acid ester suberic acid condensate, diglyceryl isostearic acid ester azelaic acid condensate , Diglyceryl isostearic acid ester sebacic acid condensate, and one or more of these are selected and used. The blending amount in the total amount of the oily cosmetic is suitably 2.0 to 60.0% by weight.
[0009]
Furthermore, in this invention, when forming the gel mix | blended with oily cosmetics, although a nonionic surfactant with a HLB value of 4-12 can be contained as a peptizer, this nonionic surfactant is included.
