Abstract

The invention discloses a liquid crystal structure-containing multi-structure emulsion and a preparation method thereof. The liquid crystal structure-containing multi-structure emulsion comprises is prepared from the following components by weight percentage: 1 to 10% of internal oil phase, 2 to 20% of external oil phase, 0.1 to 2% of lipophilic emulsifier, 1 to 15% of hydrophilic emulsifier, 1 to10% of co-emulsifier and the balance of water.

Description

technical field [0001] The invention relates to a multi-structure emulsion containing a liquid crystal structure and a preparation method thereof, belonging to the technical field of cosmetics. Background technique [0002] The multiple structure system is a composite system in which the oil-in-water (O / W) type and the water-in-oil (W / O) type coexist. Due to its unique structure and properties, it is often used as a coating carrier for hydrophilic active ingredients , used in drug delivery systems and cosmetics. It overcomes the shortcomings of the O / W type system that the water is relatively volatile and the W / O type system has a strong greasy feeling, and has the advantages of both. In the development process of new cosmetics, the multiple structure system can be said to be one of the most promising ideal systems. The advantages of the multiple structure system are mainly manifested in the following aspects: (1) Due to its multiple structure, functional components are ...
