Problems solved by technology

Among them, sunscreen creams account for the majority of commercially available products. Compared with aerosol can-type sunscreen products, their biggest disadvantage is that it is not easy to apply on a large area of ​​the body, and among them, sunscreens with high SPF are usually accompanied by It has a sticky feeling, while the thinner sunscreen has adverse experiences such as running and dripping
The sunscreen spray with LPG as the propellant is more convenient to use on a large area. However, the atomization effect is very good after the material body is sprayed by the propellant. The experience of "clouds and mist" during use may make people have safety concerns , greater risk of inhalation
In addition, sunscreen sprays that use liquefied petroleum gas as a propellant have a high content of liquefied petroleum gas in the product, and liquefied petroleum gas is a flammable substance, so there are restrictions on storage, transportation and carrying by consumers

Abstract

The invention provides a sunscreen bubble taking carbon dioxide as a propellant. The sunscreen bubble is characterized by comprising the following components, by mass: 10.5 to 38% of an oil-phase component, 0.2% to 1.5% of a thickening agent, 1% to 5% of a pH regulator, 0.3% to 3% of a preservative, 0.01% to 0.2% of an essence, 0.5 to 3% of carbon dioxide, and the balance being water. The oil-phase component includes a sun-screening agent and an emulsifying agent. According to the sunscreen bubble using the carbon dioxide as a propellant completely, the foam is dense, fine and smooth when theproduct is extruded and the product is easily pushed away on the skin surface, so that the skin feels fresh and cool without greasy feeling; and thus the product is suitable for large-area use. Moreover, the product belongs to a non-flammable product, has no inhalation risk, and is convenient to carry and transport; and the safety performance of the product is improved.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a sunscreen bubble using carbon dioxide as a propellant and a preparation method thereof. Background technique [0002] The current sunscreen products on the market are roughly divided into two categories: sunscreen cream and sunscreen spray with LPG (liquefied petroleum gas) as propellant. Among them, sunscreen creams account for the majority of commercially available products. Compared with aerosol can-type sunscreen products, their biggest disadvantage is that it is not easy to apply on a large area of ​​the body, and among them, sunscreens with high SPF are usually accompanied by It has a sticky feeling, while the thinner sunscreen has adverse experiences such as running and dripping. The sunscreen spray with LPG as the propellant is more convenient to use on a large area. However, the atomization effect is very good after the material body is sprayed by the ...
