Problems solved by technology

[0004] However, because the oil and water phases of emulsified shoe polish are in a thermodynamically unstable state, the shoe polish system is easily damaged, resulting in separation (demulsification), resulting in the product not being able to be used normally

Embodiment 1

[0013] Example 1. Shoe polish composite emulsifier is composed of 10% sucrose acetate isobutyrate, 30% glyceryl rosin, 40% sucrose ester SE-11 and 20% Tween 20. At a temperature of 40℃, add sucrose acetate isobutyrate in proportion, add glyceryl rosin while stirring, dissolve, and cool to 20℃ to obtain a balanced oil; weigh sucrose ester SE-11 and Tween 20, add water to dissolve, while Add the prepared balance oil while stirring; it is pre-emulsified twice by an APV homogenizer under (first-stage pressure 100bar, second-stage pressure 40bar) to make a composite compound emulsifier.

Embodiment 2

[0014] Example 2. The shoe polish composite emulsifier is composed of 20% sucrose acetate isobutyrate, 40% glyceryl rosin, 20% sucrose ester SE-11 and 20% Tween 20. At a temperature of 40℃, add sucrose acetate isobutyrate in proportion, add glyceryl rosin while stirring, dissolve, and cool to 20℃ to obtain a balanced oil; weigh sucrose ester SE-11 and Tween 20, add water to dissolve, while Add the prepared balance oil while stirring; it is pre-emulsified twice by an APV homogenizer under the pressure of (first-stage pressure 150bar, second-stage pressure 50bar) to make a composite compound emulsifier.

Abstract

The invention relates to a shoe polish compound emulsifier and a preparation method thereof. The shoe polish compound emulsifier comprises 10 to 20% of sucrose acetate isobutyrate, 20 to 40% of rosin glycerin ester, 20 to 40% of sucrose ester SE-11 and 10 to 20% of tween-20. The preparation method comprises following steps: (1) at a temperature of 40 DEG C, rosin glycerin ester is added into sucrose acetate isobutyrate with stirring at the ratio listed above, and is cooled to 20 DEG C after dissolving so as to obtain an equilibrium oil; (2) sucrose ester SE-11 and tween-20 are dissolved in water, and the equilibrium oil is added into the mixture with stirring; (3) the mixture is pre emulsified for two times by an APV homogenizer (first grade pressure 100 to 150bar, and second grade pressure 40 to 50bar) so as to obtain the compound emulsifier. Stability of the shoe polish compound emulsifier is high, and brightness is excellent.

Description

[0001] Technical field: [0002] The invention relates to the field of shoe polish preparation, in particular to the field of shoe polish composite emulsifier preparation. Background technique: [0003] Emulsified shoe polish is a kind of shoe polish with special properties. It is usually an emulsion made by dispersing water-insoluble oil-soluble ointment into distilled water through surfactants (complex emulsifiers) and emulsifying equipment. Emulsified shoe polish can enable various oil-soluble ointments to be used in water products. [0004] However, due to the thermodynamically unstable state of the oil and water phases of emulsified shoe polish, the shoe polish system is easily damaged, causing separation (demulsification), resulting in the product cannot be used normally. Therefore, the key to the stability of emulsified shoe polish lies in the choice of compound emulsifier and emulsification method. [0005] Summary of the invention: [0006] The purpose of the patent of ...
