Description

Emulsified toning lotion and preparation method thereof

Technical Field

The invention discloses a lotion, in particular to an emulsified lotion, and belongs to the technical field of skin care products.

Background

In general, the moisturizing components on the facial skin are almost completely removed after cleansing, and therefore it is necessary to rapidly restore the moisturizing system of the skin, and in this respect, the lotion is a very simple and effective formulation, and the creams are inferior to the lotion in terms of rapidly reestablishing the moisturizing environment of the skin. The lotions can be classified into transparent type and emulsion type according to their forms. The transparent toning lotion is difficult to add oily skin care raw materials, so the oily moisturizing effect is generally not ideal; the emulsified toning lotion makes up the defects of transparent products, and certain oily components can be added into the formula, so that the moistening property of the product is improved.

The water phase and oil phase in the emulsified cosmetic water are not single substances generally, but are a mixture of multiple water-soluble components and oil-soluble components, for example, the water phase can be composed of water and water-soluble high molecular polymer, and the oil phase can be composed of white oil, fatty acid, synthetic oil, etc. In order to disperse the oil phase uniformly and stably in the water phase, it is necessary to add an emulsifier to the oil-water system and emulsify the oil by a certain emulsification method.

The milky liquid cosmetics on the market are various in types, but the formula and the preparation process of the milky liquid cosmetics cannot be knocked out, the milky liquid cosmetics seem to be the same simple mixed preparation method, and the milky liquid cosmetics are lack of scientificity. Taking cosmetics of an O/W emulsification system as an example, the documents of modern cosmetic science and technology, cosmetic formula technical manual, application of surfactant in formula and the like are consulted, and the most conventional and popular preparation method introduced by the documents is that water phase in the formula is poured into oil phase or oil phase in the formula is poured into water phase, and then the materials are mixed and uniformly dispersed together by matching with external force for homogenization. Although the method is simple and convenient, the selection of the emulsifier is not high, and the common emulsifier basically can meet the requirements, the technology cannot meet the scientificity of the cosmetics, the stability and safety risk of the product are high, and the skin care effect of the cosmetics is also reduced by half.
