Abstract: The specification relates to an emulsion composition of a formulation that can stably comprise an active substance through a biomimetic structure and can effectively deliver the active substance into the skin. The disclosure uses biocompatible natural vegetable proteins and macromolecules to mimic plant seeds with components and form a morphologically simulated structure of stem cells, so that various efficacious substances can be stably comprised in a high content in the formulation, and high skin absorbability of active substances can be provided. Accordingly, the disclosure can not only solve the safety issues caused by the use of conventional synthetic chemicals, but also enhance the effect of a cosmetic composition or pharmaceutical composition comprising an active substance by stabilizing the active substance in a formulation and effectively absorbing the active substance into the skin.

Abstract: The present specification relates to a chiral resolution method of a stereoisomer mixture, comprising a step of mixing a stereoisomer mixture of compounds, in which an amine group is bound to an asymmetric carbon atom, with a chiral auxiliary and salt-forming auxiliary compound, wherein the chiral auxiliary is an O,O′-diacyltartaric acid derivative, more specifically, a 2,3-dibenzoyl-tartaric acid or O,O′-di-p-toluoyl tartaric acid, the salt-forming auxiliary compound is mandelic acid or camphorsulfonic acid, and an optical isomer having a high level of optical purity can be obtained by using the method. Therefore, according to one aspect of the present invention, the method can be useful in pharmaceutical or cosmetic field when preparing an optical isomer having a high optical purity.
