Is sunscreen spray a physical sunscreen?

Both, but it is not recommended to use sprays containing physical sunscreens because the physical sunscreens titanium dioxide or zinc oxide can easily be absorbed into the body when using the spray, and these two ingredients are harmful to the body.

Physical sunscreen: Sunscreen agents in sunscreen use physical methods to block ultraviolet rays, such as titanium dioxide and zinc oxide. When sunlight shines on the surface of titanium dioxide or zinc oxide, these fine particles can reflect ultraviolet rays, thereby reducing absorption. Use physical principles to block ultraviolet rays.

Chemical sunscreen: The sunscreen in sunscreen first absorbs ultraviolet rays, then converts them into a lower state of energy and releases it, thereby avoiding damage from ultraviolet rays. Sunscreens that use chemical principles to block ultraviolet rays are called chemical sunscreens. The advantage of chemical sunscreens is that they feel good to use, but some may cause contact allergies and trigger dermatitis. Sunscreens are called physical sunscreens. Physical sunscreens are non-irritating but can easily cause whitening and oiliness.

Is sunscreen spray flammable and explosive?

High-pressure canned items such as sunscreen spray are flammable and explosive and cannot be brought into the subway. Since the subway is a confined space with a large flow of people, the security requirements are very high. Some flammable and explosive items are prohibited from being brought into the subway not because they can cause a large fire, but because once a danger occurs, they can easily cause mass panic and lead to stampedes. For example, sprays, hairsprays, mousses, etc., are generally marked with the words "flammable and explosive" on the bottles, so citizens must pay more attention when purchasing and carrying them to avoid inconvenience.

Okay, friends, you know that sunscreen spray has both physical and chemical sunscreen.
