Description

Foundation cream and preparation method thereof

Technical Field

The invention relates to the technical field of daily chemical industry, in particular to foundation cream and a preparation method thereof.

Background

The emulsion cosmetic mainly comprises two systems of 0/W type and W/O type. As is well known, the W/O type body system has good antibacterial performance and beautiful appearance, and the performance makes the W/O type body system more applied to cream products such as foundation cream and the like. However, at the same time the W/O type systems have some inherent disadvantages: a very high oil phase is required, and a refreshing formula cannot be easily prepared; in addition, wax macromolecular grease is mostly required to be added as an external phase to increase the viscosity of the emulsion and improve the stability of the emulsion, so that the skin feel of the product is poor, the stability of the formula is greatly influenced by the change of temperature, and the regulation and control difficulty of the formula design is greater than that of an O/W system. For example, most of the prior foundation cream products form a continuous closed oil film on the skin through a wax macromolecular grease external phase and then by combining with lipophilic titanium dioxide added into the product, so as to achieve the purposes of resisting water and sweat. However, the skin feel of the product is not refreshing enough due to poor air permeability of the oil film, so that the product always gives a sticky feeling, and the sealing property is too strong, so that sweat is easily discharged from pores of the substrate, and the oil film is impacted from the bottom layer, thereby causing the adverse effects of 'makeup' and 'powder removal'.

At present, a large amount of studies have not been made on W/O type systems in which wax-based macromolecular oils and fats are not added as an external phase. Further development is still needed on how to select a proper emulsifier for the W/O type emulsifying system so as to obtain a foundation cream formula which has good stability, no greasy feeling, good water resistance and difficult sweating and make up.
