Description

Sun-proof bubble using carbon dioxide as propellant and preparation method thereof

Technical Field

The invention relates to the technical field of daily chemical products, in particular to a sun-proof bubble taking carbon dioxide as a propellant and a preparation method thereof.

Background

The current commercial sunscreen products are classified broadly into sunscreen creams and sunscreen sprays using LPG (liquefied petroleum gas) as a propellant. Among them, sunscreen creams account for most of the commercial products, and the biggest disadvantage of sunscreen creams is that they are not easy to be applied on a large scale on the body, and among them, sunscreen creams with high sun protection index are often accompanied by sticky feeling, while thinner sunscreens have poor experience of body flow, dripping, etc. The sun-proof spray taking LPG as a propellant is convenient to use in a large area, however, the atomization effect of the liquid body sprayed by the propellant is very good, the experience of cloud and mist turning in the using process may cause people to have doubts in the aspect of safety, and the inhalation risk is large. In addition, the sun-screening spray using liquefied petroleum gas as propellant has the limitations in storage, transportation and carrying by consumers because the liquefied petroleum gas content in the product is high and the liquefied petroleum gas belongs to combustible substances.
