Abstract

The invention relates to the technical field of skin care products, specifically a water-like sunscreen spray produced by high-pressure microjet. In the present invention, fumed silica and polyethylene glycol-32 are compounded with other chemical sunscreen agents and other ingredients at the same time, and then the mixture is subjected to high-pressure micro-jet homogenization treatment to form a stable water-like sunscreen spray, which is installed in An ordinary liquid water mist spray bottle can spray even and extremely fine mist droplets through an ordinary liquid water mist nozzle, which can be sprayed evenly on the skin without the need to use hands to apply it evenly. It is extremely convenient to use, especially for the skin. Sun protection for areas of skin that are difficult to apply with hands, such as the back. Moreover, the watery sunscreen spray of the present invention does not need to add ingredients such as emulsifiers and propellants. The product is mild and has little irritation to the skin, and is suitable for direct spraying on the face. In addition, since the aqueous sunscreen spray of the present invention has no propellant, it is safe and can be carried around normally.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a water-like sunscreen spray made by high-pressure micro-jet. Background technique [0002] The types of sunscreen spray products today can be divided into two types: aerosol sunscreen spray and manual pump sunscreen spray. Aerosol sunscreen sprays contain a lot of ethanol and jet propellants, so this type of product is less mild and is not suitable for direct spraying on the face, and aerosol sunscreen sprays cannot be carried on airplanes, high-speed rail and other transportation vehicles. Therefore, the application is limited. The paste of the manual pump sunscreen spray has a high viscosity, and the paste cannot be sprayed out with a general nozzle, and a specially designed nozzle is required. Even so, the mist droplets sprayed by the manual pump sunscreen spray are still not fine enough and uneven. The outer ring is more than the middle, so it needs to be applie...
