What about artificial snow?

Artificial snow, also known as Fu Na, refers to the process of artificially turning water (steam) into snowflakes or similar snowflakes through certain equipment or physical and chemical means.

The manufacturing methods of artificial snow are divided into gun barrel type and borneol crushing type. The density of natural snow is about 328kg/m3, while that of artificial snow is about 856kg/m3. In essence, artificial snow is the same as natural snow, but the density of artificial snow is higher. Therefore, under the same conditions, the same volume of artificial snow melts slower than natural snow.

Sodium polyacrylate is a new functional polymer material and an important chemical product. The solid product is white (or light yellow) block or powder. Food-grade sodium polyacrylate can be used as an additive in bread, cake, juice, ice cream, alcohol and other foods. Industrial sodium polyacrylate can be used for papermaking or as a water treatment agent.

Chen Dong, an associate professor at beijing university of chemical technology College of Materials Science and Engineering, said that generally speaking, sodium polyacrylate is non-toxic and tasteless, which is white powder after drying and transparent colloidal liquid after dissolving in water. "Under normal circumstances, high-purity food-grade sodium polyacrylate is mild in nature, non-irritating to human skin and harmless to a small amount of food."

However, experts said that from the introduction of "artificial snow powder" currently sold online, the sodium polyacrylate used is probably industrial sodium polyacrylate, and parents are not recommended to use it for their children. "Because of industrial-grade sodium polyacrylate, there may be other chemical residues during processing, which may be harmful to human body.

Experts further explained that "if the residue comes into contact with the eyes or is eaten by people, the harm will be even greater." Chen Dong reminded that if the "artificial snow powder" accidentally enters the eyes during use, it should be washed with clear water immediately, but if it is eaten by mistake, it must go to the hospital for medical treatment and be handled by professionals.
