Liquid bandages, also known as liquid skin or collodion bandages, are a type of topical skin protectant that forms a thin, flexible, and waterproof barrier over minor cuts, scrapes, and abrasions. They are a convenient and effective way to keep wounds clean and protected while they heal.
Liquid bandages are typically made from a combination of polymers, such as nitrocellulose and polyvinyl acetate, and solvents, such as ethyl acetate and butyl acetate. When applied to the skin, the liquid bandage dries quickly to form a clear, protective film. This film helps to keep out dirt and bacteria, and it also provides a barrier against moisture. Liquid bandages are also waterproof, so they can be worn while swimming or bathing.
