AI Technical Summary

Technical Problem

Existing methods for producing W/O/W-type emulsions face challenges in achieving a linear appearance of the dispersed phase, leading to high equipment costs and inefficient production, and lack the aesthetic appeal provided by W/O/W-type emulsified cosmetics.

Method used

A method involving the mixing of an aqueous gel containing a water-soluble polymer with a W/O type emulsion under specific stirring conditions using a rotary mixer with blades, resulting in a visible linear dispersion of the W/O type emulsion within an aqueous gel continuous phase.

Benefits of technology

The W/O/W type emulsified composition offers a novel aesthetic appearance with a linear dispersed phase, while enabling efficient production using general-purpose equipment and maintaining stability over time.

Abstract

This invention provides a W / O / W type emulsion composition suitable for use as a cosmetic, which has a novel appearance with high aesthetic appeal, and an efficient method for producing the same. [Solution] This is a W / O / W type emulsion composition in which a dispersed phase consisting of a W / O type emulsion is dispersed in a visible linear form within a continuous phase consisting of an aqueous gel containing a water-soluble polymer. Carbomer or water-soluble polysaccharides are preferred as the water-soluble polymer, and the oil phase of the W / O type emulsion preferably contains a water-retaining oil. This O / W type emulsion composition can be obtained by mixing an aqueous gel containing a water-soluble polymer with a W / O type emulsion, and then stirring and mixing it using a rotary mixer equipped with stirring blades at a peripheral speed of 1 to 10 m / s.
