AI Technical Summary
Technical Problem
Conventional cosmetics without microplastic beads have inferior feel and reduced effectiveness in terms of texture and SPF compared to those using microplastic beads.
Method used
A composite powder is developed by coating spherical powders with an average diameter of 1 to 20 μm with semi-solid or solid oils, amphoteric surfactants, and/or oil-based gelling agents, to which plate-like powders with an average diameter of 50 μm or less are attached, enhancing the feel and performance.
Benefits of technology
The composite powder provides a feel similar to microplastic beads with improved light diffusivity and SPF, significantly enhancing texture evaluations such as smoothness and moistness.

Abstract
To provide a more effective composite powder as a substitute technology for microplastic beads.SOLUTION: A composite powder contains: spherical particles with an average particle size of 1-20 μm, coated by (A), and (B) and / or (C), where (A) is at least one selected from oil solutions that are semisolid or solid at room temperature, (B) is an ampholytic surfactant and (C) an oil-based gelator; and plate-like particles with an average particle size of 50 μm or less, bonded to the spherical particles. Also provided are cosmetics containing the same.SELECTED DRAWING: Figure 1
