Description

 Specification

 Oil-based cleansing fee

 Technical field

 [0001] The present invention relates to a semi-solid or solid oil-based cleansing agent, and more particularly, has good detergency, ease of use, and feeling of use, has excellent transparency, and has excellent high-temperature stability. Further, the present invention relates to an oil-based cleansing agent having an excellent massage effect. Background art

 [0002] In recent years, with the spread of hard makeup cosmetics such as oily mascara and hard-to-drop lipstick, high cleansing ingredients have been required to have high detergency, and have high water resistance and long lasting! Makeup cosmetics, etc. The demand for oil-based cleansing charges, which can remove the oil, is increasing rapidly.

 [0003] However, since a general oil-based cleansing agent is mainly composed of liquid oil, its usability such as difficulty in picking it up on a finger or skin wiping after wiping or rinsing has been found. There was a problem in the feeling of use, such as a rattle. In order to solve these problems, an oil-based cleansing agent (e.g., Patent Document 1) in which an oil-based component is gelled with bentonite, an oil-based gelling agent, or solid oil to give a viscosity to the system has been studied. .

 [0004] On the other hand, oily solid cosmetics having a transparent appearance and aesthetic properties include those containing polyamide resin (for example, Patent Documents 2 and 3) and those containing 12-hydroxystearic acid ( For example, Patent Documents 4 and 5) and compounds containing dextrin fatty acid esters (for example, Patent Document 6) are known.

 Patent Document 3: Japanese Patent Publication No. 52-7067

 Disclosure of the invention

Problems the invention is trying to solve [0006] Cosmetics in which the oil component is gelled with bentonite, an oily gelling agent, or solid oil while imparting viscosity to the system, while having excellent usability, are gelled even if they have excellent usability. The agent itself was cloudy due to the agent itself, the aesthetic appearance was poor, and there were also points that were unpleasant to the touch, such as stickiness after use due to solid oil and the like.

 [0007] In addition, when the cleansing fee is spread on the skin and blended with the makeup fee! / ヽ ぅ The rubbing action promotes blood circulation of the skin, and softens and brightens the skin, similar to massage. However, these effects are expected to increase if the cosmetic used at that time is viscous and has an appropriate resistance on the skin. However, the cleansing agent, which is obtained by gelling oil-based components with bentonite, an oil-based gelling agent, or solid oil, and giving the system a viscosity, significantly reduces the viscosity of the system due to the rubbing action at the time of use. No effect was obtained.

 [0008] On the other hand, among the oily solid cosmetics having a transparent appearance, those containing a polyamide resin have the drawback that oil bleeds due to aging or temperature change and the storage stability is immediately deteriorated. In addition, those containing 12-hydroxystearic acid have excellent transparency in appearance, but have somewhat poor temperature stability, while those containing dextrin fatty acid esters have higher transparency and system hardness. I was not satisfied with both. In addition, these transparency-related technologies are technologies that assume transparent lipstick, and when applied as cleansing ingredients, they were not powerful enough to withstand the feeling of use, such as being stretchy and sticky.

 [0009] That is, under the present circumstances, no oil-based cleansing agent having a transparent or translucent appearance, having an excellent feeling in use, having no viscosity reduction due to a rubbing action during use, and having an excellent massage effect has not been found in the field.

 Means for solving the problem

[0010] Under such circumstances, the present inventors have conducted intensive studies on the composition of an oil-based cleansing material in order to solve the above-mentioned problems. As a result, by combining a specific polyamide-modified silicone, a surfactant having a specific property, and an ester oil in combination, it has good detergency, is transparent or translucent in appearance, and has excellent aesthetics. Because of its semi-solid or solid form, it has good usability such as easy handling because it can be removed without spilling during use, and massage that can be expected to promote blood circulation and remove keratin It has been found that an oil-based cleansing agent having both effects and excellent high-temperature stability can be obtained, and the present invention has been completed.

 [0011] Furthermore, the rubbing action with the oil-based cleansing agent causes the cleansing agent to penetrate deep into the texture of the skin merely by a massage effect such as blood circulation promotion, dissolves the components to be washed, and removes the components to be washed onto the skin. At the same time, it was found that the cleansing effect, that is, raising the cleansing effect, was enhanced.

 That is, the present invention provides the following components (A) — (C):

In the present specification, the semi-solid form or the solid form refers to a gel hardness (specimen storage temperature of 25 ° C, a pressure-sensitive shaft (adapter)) measured by a rheometer (Rheometer NRM-2002D.D manufactured by Fudo Industry Co., Ltd.). In a penetration test at a needle diameter of ΙΟπιπι φ and a table moving speed of 60 mmZmin, it means that the load applied to the pressure-sensitive shaft when the pressure-sensitive shaft is pushed to a depth of 5 mm is 15 gf or more, preferably 50 gf or more.

 [0032] The oil-based cleansing agent of the present invention is more preferably transparent or translucent. In this specification, transparent or translucent refers to a state (semi-transparent) in which a paper character (about 11 fonts) placed at the bottom of a beaker can be read when a glass beaker is filled with the product of the present invention at a depth of 15 mm. Transparent) force also means more transparent.

 As described above, in order to make the oil-based cleansing agent of the present invention transparent or translucent, it is preferable to use a surfactant having an amide group as the component (B) of the present invention. Since this surfactant has excellent compatibility with the component (A), it enhances the stability of the oil-based cleansing agent and also contributes to making the appearance of the oil-based cleansing agent transparent or translucent.

 [0034] In addition to the above-mentioned components, a volatile silicone such as decamethylcyclopentasiloxane can be added to the oil-based cleansing agent of the present invention. By blending these volatile silicones, cosmetics such as lipstick and mascara become more familiar with cleansing agents, and as a result, cleansing agents with higher cleansing and extremely excellent stain removal can be obtained. When these volatile silicones are contained, the content is preferably about 3 to 25% based on the total composition.

[0035] The oil-based cleansing agent of the present invention contains the above-mentioned components, and the components commonly used in cosmetics, such as oils and surfactants, to the extent that the effects of the present invention are not impaired depending on the purpose. , Water-soluble polymer, clay mineral, powder, water-soluble moisturizing ingredient, beauty ingredient, antioxidant, antiseptic It is possible to mix ingredients such as agents, chelating agents, pH adjusters, coloring agents, medicinal ingredients, and fragrances.
