Problems solved by technology

[0004] However, in the case of using these highly hydrophilic surfactants such as polyglycerol fatty acid esters and sucrose fatty acid esters, not only functions such as low water resistance of the coating film but also stickiness and the like are caused. There is a problem that the feeling of use decreases with the decrease of water resistance

Abstract

Provided is an oil-in-water emulsion composition which uses a mannosylerythritol lipid and imparts a favorable and stable sensation when applied. The oil-in-water emulsion composition is characterized in comprising the following components (A) to (C): a specific UV absorber (A), a sorbitan fatty acid ester (B) having an HLB of 6 or less, and a mannosylerythritol lipid (c). The HLB of a mixture of surfactants in the composition is less than 8, and the content ratio of component (A) relative to 100 parts by mass of the total amount of the oily components is at least 75 parts by mass.

Description

technical field [0001] The present invention relates to an oil-in-water emulsion composition excellent in touch. Background technique [0002] In recent years, oil-in-water emulsion compositions have been used as sunscreens because they have a better texture when applied to the skin than water-in-oil emulsion compositions. However, ultraviolet absorbers used in sunscreens have poor solubility in solvents and are insoluble in humectants such as glycerin or in water, making it difficult to stably blend them into oil-in-water emulsion compositions. Here, an oil-in-water emulsified formulation using a surfactant having an oxyalkylene group having relatively good compatibility with an ultraviolet absorber is considered (Patent Document 1). [0003] So far, surfactants having oxyalkylene groups such as ethylene oxide, propylene oxide, and butylene oxide in the molecule have been widely used in the fields including cosmetics and pharmaceuticals, but in recent years, related to the...
