Sunscreen bar containing water-soluble component and preparation method thereof

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.

Description

technical field

[0001] The invention relates to the field of special cosmetics, in particular to a sunscreen stick containing water-soluble components and a preparation method thereof. Background technique

[0002] At present, there are many types of sunscreen cosmetics for UV protection on the market. Traditional sunscreen products include sunscreen lotion / lotion, sunscreen, sunscreen spray, etc. In recent years, sunscreen sticks, with their advantages of high SPF, portability, and easy application, have gradually entered the field of vision of consumers, especially in Western countries. However, since the sunscreen stick is a pure oil system, and contains a large amount of sunscreen agents and waxes with thick and greasy skin feeling, its greasy skin feel discourages consumers in eastern countries who prefer a moisturizing skin feel, so domestic cosmetics are rarely seen Manufacturers produce sunscreen sticks, which limits the popularity of sunscreen sticks in China.

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.
