Description

200534871 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to an oily cleaner, and more specifically, it is related to the fact that it does not become cloudy and thickened even if it is mixed with water, and it has no irritation to the mucous membranes of the eyes. A cleansing effect and an oily cleansing agent. [Prior art] Cosmetic cleaning compositions can be roughly divided into water-based cleaners and oily cleaners

^ Water-based cleaners are now known as emulsion types consisting of an aqueous solution of surfactant ethanol, as well as types of water-based gels that make surfactants thicker by polymers. In addition, oil-based cleaners are known as cream types in which the emulsified emulsifier is inverted by massage to exert a cleaning function, and oil-based types composed of a surfactant oil solution. It is known among these that especially the oily type has a high cleaning effect. In recent years, because the trend of cosmetics is to prevent secondary sticky types such as lipsticks, the type containing mascara that is polymerized and oxidized, has become mainstream, and oily types have a very high value in the market. The oily type cleaning composition is composed of a nonionic surfactant, an oil component and a small amount of water to form an oil solution of inverse cells. The oil solution of the inverse cells is a surfactant that forms a hydrophilic group in the oil. Fit. The water system forms a solubilized single phase in the vicinity of the aggregation of hydrophilic groups, and becomes completely transparent. Due to the structure of the microcell, the oil type II can completely absorb water transparently: the force ', also called the solubilization amount, has a limit. Exceeding the amount of solubilization / this entry is due to the coexistence state (two-phase state) with other phases, and the whole becomes cloudy due to the difference in refractive index of the -phase. The types of coexisting phases are different from each other, which makes the cleaning agent unable to achieve the desired cleaning performance, which will give the user the impression that the cleaning performance is strongly reduced. In addition, when water exceeding the soluble amount is mixed, the composition thickens, and it is impossible to apply cosmetics smoothly, and it is difficult to dissolve the cosmetics uniformly, and there are problems in that it does not exhibit good massage characteristics. Due to the above points, of course, when using an oily cleanser, it cannot be used with wet hands, nor can it be used on a wet face after shampooing in the bathroom. This becomes a limitation of use. In this regard, Japanese Patent Application Laid-Open No. 2000-327529 discloses a polyglycerol having an HLB10 or higher and a polyhydric alcohol having a dihydric or higher viscosity, and a cleanser which is easy to melt evenly with cosmetics even when the skin is moist. However, this method cannot prevent the appearance of white turbidity, and because the composition is thickened, it is difficult to uniformly dissolve with the cosmetic product. In addition, Japanese Unexamined Patent Publication No. 6-16524 and Japanese Unexamined Patent Application No. 20000279 are described in combination with a nonionic surfactant and an amphoteric surfactant. The combination of glycerol shout derivatives is a cleansing agent that has a cleansing power even when the hands are wet with two feet. However, it is not sufficient to massage and prevent the appearance of cloudiness. It also becomes a problem for the eyes and other mucous membranes. [Summary of the Invention] The present invention deals with the conventional problems as described above, and the purpose thereof is to provide a liquid oily cleanser 'which, even when mixed with water, will not become cloudy or difficult to expand due to increased viscosity, or Mixing and melting will result in poor massage performance and good makeup removal effect, and it will not irritate the eyes and other mucous membranes. According to the present invention, there is provided an oily cleaner containing (a) 50 to 95% by mass of a liquid oil component, (b) an alkyl chain having a carbon number of 14 or more, and only ethylene 6 being a nonionic interface of 9 to 16 The active agent, (c) a fluorinated fatty acid and / or a higher alcohol (d) a compound having a polyoxypropylene having a molar number of 5 to 35 in the molecule. In the present invention, the compound having a polyoxypropylene (pop) group in the molecule of the component (d) is preferably selected from pop sorbitol, pop diglycerol, POP glycerol, POP butyl ether, or POP · POE (polyoxygen At least one of the ethylene) random copolymers is particularly preferably POP sorbitol. In addition, it is preferable that the compounding of the nonionic surfactant having an alkyl chain carbon number of the above component (] 3) of 14 or more and an HLB of 9 to 16 is 5 to 40% by mass, The compounding amount of the higher fatty acid and / or higher alcohol of the component (c) is 1 to 10% by mass, and the compounding amount of the polyoxypropylene-based compound having a mole number of 3 to 35 is added to the molecule of the component (d). It is 丨 ~ ⑺ mass%. Further, the higher fatty acid and / or higher alcohol of the component (c) is preferably a branched higher fatty acid or higher alcohol. According to the present invention, with the above-mentioned structure, even when water is mixed, the cleaning performance of the south can be maintained, and the appearance is free of turbidity and thickening, and does not cause a decrease in massage performance. Agent. [Embodiment] 100524.doc 200534871 In order to solve all the above-mentioned problems, it is found that the liquid oil content, a specific ammonium ionic surfactant, The high-grade fatty alcohol and / or the higher alcohol, and the high-grade alcohol; # t. At, the oily cleaning of polyoxypropylene-based compounds solves the above problems and completes the present invention. The following describes the best practice of the present invention. In addition, this specification and the attached patent application 囷 囷 will use the early number form, such as one, the (a, an, the) is in addition to the context /] fresh also contains a plurality of objects. (a) Liquid oil component The liquid oil component used in the present invention is not particularly limited as long as it is a liquid oil component generally used in cosmetics, and any type may be used. I.
