Abstract

The invention relates to the technical field of skin care products, in particular to a water-like sunscreen spray prepared through high-pressure micro-jet. Gas-phase silicon dioxide and polyethylene glycol-32 are simultaneously compounded with other chemical sunscreen agents, then high-pressure micro-jet homogenization treatment is carried out on the mixture, and the stable water-like sunscreen spray can be formed. The water-like sunscreen spray is contained in a common liquid spray bottle, and uniform and fine droplets can be sprayed out through a liquid spray nozzle, can be uniformly sprayedon skin, do not need to be uniformly smeared by hand and are very convenient to use. The water-like sunscreen spray particularly facilitates sunscreen protection of backs and other skin areas difficult to be smeared by hand. An emulsifier, a propellant and other components do not need to be added into the water-like sunscreen spray, so that the product is mild, has little irritation on the skin and is suitable for being directly sprayed on faces to use. Besides, the water-like sunscreen spray is free of the propellant, so that the safety is good, and the sunscreen spray can be normally carried.

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...
