preparation example Construction

[0025] The preparation method among the present invention, comprises the steps:

[0026] 1) Mix the water-soluble components and water-soluble sunscreen and heat to 80.00-85.00°C, stir well and set aside;

[0027] 2) Mix the emulsifier and 5.00-10.00% emollient and heat it to 80.00-85.00°C, stir evenly and slowly add the water phase components prepared in the above step 1) while stirring quickly to obtain oil-in-water (O / W) Or water-in-oil (W / O) pre-emulsion;

[0028] 3) Mix the oil-soluble or lipophilic sunscreen, powder, and the remaining emollient and heat to 80.00-85.00°C, stir evenly, and slowly add the pre-emulsion prepared in the above step 2) while stirring quickly;

[0029] 4) When the temperature of the material prepared in the above step 3) is lowered to 65.00-75.00°C, it is injected into the mold while stirring (to prevent the powder from settling), and after cooling to room temperature, a sunscreen stick containing water-soluble components is obtained.

Abstract

The invention discloses a sunscreen bar containing a water-soluble component, which belongs to the technical field of special cosmetics. The sunscreen bar containing water-soluble component is prepared from the components of, by weight, 5.00 to 40.00 part of sun-screening agent, 1.00 to 10.00 part of emulsifying agent, 1.00 to 30.00 part of water-soluble component, 10.00 to 92.00 parts of emollient and 1.00 to 20.00 part of powder. According to the invention, the water-soluble component is added into the sunscreen bar; the defect that water-soluble components (a water-soluble skin conditioner,a sun-screening agent, a film-forming agent, a humectant, a preservative and the like) cannot be added into a traditional pure oil sunscreen bar is overcome; the selection range of the raw materialsis widened; the formula cost and greasy feeling are reduced; moisturizing experience can be provided while moisturizing is achieved; and particularly, the sunscreen index can be increased by effectively reducing the 'window effect' by adding the water-soluble sun-screening agent which has a synergistic effect with an oil-soluble sun-screening agent.
