Problems solved by technology

[0012] The inventors of the present invention have continued to conduct intensive research to develop an oil-in-water emulsified cosmetic that blends white pond flower seed oil that is less sticky and has a moisturizing and lubricating feel. When sucrose fatty acid ester and glycerin monofatty acid ester are used as surfactants, oil droplet particles with large particle size and large particle size distribution width are formed, which are not uniform

Embodiment

[0092] Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited to the following examples.

manufacture example

[0093] Production Example: Preparation of Oil-in-Water Emulsion Cosmetics

[0094] By mixing each component in the compounding amount shown in Examples 1-10 and Comparative Examples 1-4 of the following Table 1, an oil phase and a water phase were prepared, respectively. Next, after heating the water phase and the oil phase to 80 to 85°C, the oil phase was added to the water phase, emulsified using a homomixer, and cooled to about 45°C. Then, the neutralizing agent, alcohol, and additives were added in the compounding amounts shown in Examples 1 to 10 and Comparative Examples 1 to 4 in the following Table 1, and they were uniformly stirred, whereby Examples 1 to 10 and Comparative Examples were prepared. 1 to 4 cosmetics.

[0095] After preparing the cosmetic products of Examples 1 to 10 and Comparative Examples 1 to 4, it was visually confirmed that all the cosmetic products were emulsified.

Abstract

The present invention provides an oil-in-water emulsified composition comprising white chia seed oil having uniform oil droplet particles, the oil droplet particles of the white chia seed oil having a small average particle diameter and a small particle size distribution width. In more detail, there is provided an oil-in-water emulsified composition comprising: (A) component: white chia seed oil, (B) component: N-acylglutamic acid and / or a salt thereof, (C) component : water-soluble sucrose fatty acid ester, and (D)component: glycerol monofatty acid ester.

Description

technical field [0001] The present invention relates to an oil-in-water emulsion composition and the like. Background technique [0002] When the oil-in-water (O / W) emulsion composition in which the continuous phase is the water phase is used as an external composition for cosmetics, etc., it is widely used as a cream, lotion, etc. Patent Documents 1 to 3, etc.). [0003] It is known that the particle size of the oil droplet particles, the repulsive force between the oil droplet particles, and the viscosity of the continuous phase have an influence on the stability of the oil-in-water emulsified cosmetic. For example, when the particle size of the oil droplet particles is large, the oil layer and the water phase are separated over time. Therefore, in order to improve the stability of the composition, methods using a high-pressure emulsifier such as a homogenizer and a nano-emulsifier are used, The particle diameter of the oil droplet is reduced by the D-phase emulsificatio...
