AI Technical Summary

Technical Problem

In existing microcapsule technologies, the wall material is prone to breakage, making stable storage and transportation difficult, and the binding effect with active ingredients is poor, failing to achieve stable storage and on-demand delivery of cosmetic active ingredients.

Method used

A gel shell is formed by a mixed solution of sodium alginate and edible gum to encapsulate oil phase droplets. The inner phase liquid is uniformly encapsulated in the outer phase liquid using a two-phase dripping device to form cosmetic beads, thereby achieving stable storage and on-demand release of the oil phase components.

Benefits of technology

It enhances the protection and stability of active ingredients in cosmetic beads, enabling stable storage and on-demand delivery of cosmetic active substances, while also increasing mechanical strength and thickness to ensure the stability of active ingredients under different environmental conditions.

Abstract

The present application provides a cosmetic condensation bead, a preparation method and application thereof, the cosmetic condensation bead comprises an outer phase liquid and an inner phase liquid; the outer phase liquid comprises sodium alginate, edible glue and deionized water; the inner phase liquid comprises grease; the edible glue comprises any one or a combination of at least two of carrageenan, xanthan gum, guar gum, agar, gelatin, locust bean gum or konjac gum. The present application utilizes the composite capsule formed by blending and encapsulating the cosmetic active ingredients with sodium alginate and edible glue, has a special core-shell structure, can reduce the influence of external environmental factors on the performance of the internal cosmetic efficacy material, and improve the performance stability of the cosmetic efficacy material.
