What changed

This document is a USPTO patent application (US20260083646A1) for a method of forming a dispersion comprising drops of a fatty phase within a gelled aqueous phase. The described method involves providing distinct fatty and aqueous phases, forming fatty phase drops, conveying them through a circulation duct, and recovering the dispersion. It also details the addition of an aqueous solution to the aqueous phase or within the circulation duct.

As a patent application, this document does not impose immediate regulatory obligations. However, it signifies potential innovation in formulation science, particularly relevant to industries involved in creating emulsions or dispersions, such as pharmaceuticals or cosmetics. Companies in these sectors may wish to review the application for insights into novel manufacturing techniques or potential intellectual property considerations.

Abstract

A method of forming a dispersion comprising drops having a fatty phase dispersed in a gelled continuous aqueous phase. The method includes: providing a fatty phase comprising at least one oil; providing an aqueous phase, that is substantially immiscible with the fatty phase, comprising at least water and at least one hydrophilic gelling agent capable of gelling in the presence of at least one salt; forming fatty phase drops in the aqueous phase or the gelled continuous aqueous phase; conveying the drops in a circulation duct; recovering a dispersion comprising drops and the gelled continuous aqueous phase in a container. The method further includes: before the forming step, adding, to the aqueous phase, at least one portion of an aqueous solution; and/or injecting at least one portion of the aqueous solution into the circulation duct or at the outlet of the circulation duct upstream of the container.
