Problems solved by technology

However, this method cannot prevent the appearance of cloudiness, and in addition, due to the thickening of the composition, it may be difficult to dissolve with cosmetics, and the massaging property may not be sufficient.
[0007] In addition, JP-A-6-16524 and JP-A-2001-270809 describe cleaning materials that use a combination of a nonionic surfactant and an amphoteric surfactant, and a combination of a nonionic surfactant and glyceryl ether. The combination of derivatives has a high detergency even with hands wet with water, but there are problems such as insufficient massaging properties, insufficient prevention of cloudy appearance, and irritation to mucous membranes such as eyes

Embodiment 1～10 and comparative example 1～6

[0048] An oil-based cleansing material (washing oil) composed of the compounding compositions described in the following Tables I to Table III was prepared by a conventional method, and the stability of the composition, the transparency when mixed with water, and the coating on the skin when mixed with water were evaluated. The results are shown in the table respectively for development and eye irritation. In addition, the unit of compounding quantity is mass %.

[0049] In the table, polyoxyethylene polyoxypropylene dimethyl ether is a random addition of oxypropylene and oxyethylene groups, and was prepared by the method described in JP-A-2003-113023.

[0050] The evaluation methods performed in each Example and Comparative Example are as follows.

[0051] (1) Evaluate the stability of the composition

[0052] Put the test samples of Examples and Comparative Examples into 50ml transparent glass bottles with screw caps, place them at temperatures of 0°C, 25°C, and 50°C, and ...

Abstract

A liquid oil-based detergent preparation which comprises (a) 50-95 mass% liquid oily matter, (b) a nonionic surfactant having a C14 or higher alkyl chain and an HLB of 9-16, (c) a higher fatty acid and / or a higher alcohol, and (d) a compound having in the molecule a polyoxypropylene group having a number of moles of oxypropylene added of 5-35.

Description

technical field [0001] The present invention relates to an oil-based cleansing material, and more specifically, to an oil-based cleansing material that does not become cloudy or thickened even if it is mixed with water, does not irritate mucous membranes such as eyes, and has an excellent degreasing effect and usability. Background technique [0002] Cosmetic cleansing compositions can be broadly classified into aqueous detergents and oil-based detergents. As aqueous detergents, lotion types in which the surfactant is composed of an aqueous ethanol solution, and those in which the surfactant is thickened by a polymer are known. Water-based gel type, etc. Also known as oil-based detergents are cream types in which O / W emulsions perform phase inversion by rubbing, and oil types in which surfactants consist of oil solutions. Among these, the oil type is known to be particularly high in washing effect. In recent years, in the direction of makeup, the type that prevents second...
