Which type of cyanoacrylate is used in over-the-counter liquid bandages?

1. Ethyl cyanoacrylate

2. Octyl cyanoacrylate

3. Butyl cyanoacrylate

4. Alkyl cyanoacrylate

The correct answer is: Octyl cyanoacrylate

Octyl cyanoacrylate is commonly used in over-the-counter liquid bandages due to its favorable properties. This specific type of cyanoacrylate forms strong bonds quickly and provides a flexible, waterproof seal that is essential for protecting wounds while allowing for some movement of the skin. It also has a lower irritation potential compared to other cyanoacrylates, making it more suitable for use on sensitive skin. Its adhesive strength and flexibility make it ideal for applications where a durable bond is needed, such as in medical adhesives for skin. This bonding capability helps to protect against infection and allows for faster healing, making it the preferred choice in consumer products designed for self-application. In contrast, other types such as ethyl cyanoacrylate, although effective in various medical applications, tend to be more irritating to the skin and do not provide the same level of flexibility and durability that octyl cyanoacrylate offers for liquid bandages.
