Uncover the production process of sunscreen spray

Summer is here, how can you protect your skin? No doubt people use sunscreen spray more. The sunscreen spray is popular among users because of its convenient use and good experience effect. So, do you know how sunscreen spray is produced? Here are the secrets of sunscreen spray production process and required equipment.

Sunscreen spray is an aerosol product, which means that lotion or suspension is sealed in a pressure resistant container with a special valve system together with a suitable propellant, and the contents are sprayed out as mist with the pressure of the propellant. There are two packaging forms of sunscreen spray, one is on valve kind and two is bag on valve kind.

On valve kind

The propellant and material body of the on valve kind packaging sunscreen spray are mixed in the Aerosol Can. The propellant is used to pressurize to push the material body to spray out and assist in the material body atomization. It is sprayed together with the material body. If propane butane is seen in the composition list of the general sunscreen spray, it is the unitary sunscreen aerosol. Propane butane is flammable gas, so it is not very safe and environmentally friendly.

Bag on valve kind

The bag on valve kind packaging sunscreen spray also has a container in the aerosol can (usually prone to volume change under pressure), which forms two separation spaces with the can body. The propellant exerts pressure on the inner container outside, and the inner container is connected with the valve. Since the propellant is separated and completely disconnected from the outside, the safety and environmental protection are better. At present, the dual package sunscreen spray is more popular with consumers, with good experience effect, and can also be taken on trains and planes.
