Problems solved by technology

[0006] However, since liquid foundations use liquid oily bases regardless of whether they are oily or emulsified, stickiness tends to occur during application (smearing) or after application, and it is difficult to obtain the dry skin feel of powdery foundations in this respect.

Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described in detail.

[0032] [Oil Absorbing Hydrophobic Powder]

[0033] As the oil-absorbing hydrophobic powder suitably used in the present invention, cross-linked polymethyl methacrylate, nylon porous powder, and the like are suitably used. The material itself may be lipophilic, or the material may be hydrophilic but coated with a lipophilic substance, but in the case of coating, it is preferably lipophilicized into the pores.

[0034] The maximum possible oil absorption energy of the oil-absorbing hydrophobic powder is preferably 90% by mass or more relative to the powder. If the maximum possible oil absorption capacity is less than 90% by mass, sufficient oil cannot be absorbed during application, and good skin touch may not be obtained.

[0035] The blending amount of the oil-absorbing hydrophobic powder in the composition is 5 to 25% by mass, preferably 10 to 20% by mass. If it is less than 5% by mass,...

Abstract

The problem to be solved by the present invention is to provide an oil-in-water composition that spreads well at the time of application and can give a dry touch on the skin after application. The oil-in-water composition is characterized by comprising: an aqueous medium containing water and a water-soluble and volatile organic solvent, oil dispersed in the aqueous medium, and an oil-absorbing hydrophobic powder capable of absorbing the aqueous medium and the oil In the composition, the oil-absorbing hydrophobic powder maintains an aqueous medium.

Description

[0001] related application [0002] This application claims the priority of Japanese Patent Application No. 2016-051579 submitted on March 15, 2016, which is incorporated herein. technical field [0003] The present invention relates to an oil-in-water composition, and particularly to an improvement of an oil-in-water composition using an oil-absorbing hydrophobic powder. Background technique [0004] Usually, skin care and make-up operations use cleansing cosmetics such as lotion to adjust the skin condition, and then use foundation to correct blemishes (tone, or unevenness) of the skin, and then adjust the appearance by imparting the target tone and imprint (shadow) as necessary . [0005] There are powder foundations, liquid foundations, and the like as the above-mentioned foundations. In particular, liquid foundations are excellent in spreading properties, and demand is increasing. [0006] However, since liquid foundations use a liquid oily base regardless of whether ...
