Technical Field

The invention relates to the technical field of cosmetics, in particular to a water-in-oil type emulsified composition, foundation liquid and a preparation method thereof.

Background

With the pursuit of people for aesthetic feeling becoming higher, make-up cosmetics have become an indispensable living article for modern fashion people. Make-up cosmetics are of many varieties and mainly comprise various products such as foundation, honey powder, lipstick, eye shadow, rouge, mascara and the like. These make-up cosmetics generally contain both an aqueous phase component and an oil phase component, and an emulsifier is a raw material that must be added in order to sufficiently mix the aqueous phase component and the oil phase component. After the emulsifier is added to the oil-water system, the water and oil can be mixed with each other to form an emulsion. The powder base liquid belongs to emulsion, and comprises oil-in-water powder base liquid and water-in-oil powder base liquid. Regardless of the type of the powder base liquid, the user hopes that the product quality is stable, and the better use experience can be given to the user. However, the existing water-in-oil foundation liquid often has the phenomena of demulsification and layering, poor stability of an emulsifying system, poor skin feel and poor make-up holding effect.
