Vegan condoms are a type of condom that are made without any animal-derived materials. This means that they do not contain casein (a protein found in milk), which is often used as a lubricant in traditional condoms. Instead, vegan condoms may use plant-based lubricants such as aloe vera or carrageenan. They are also free of any animal testing. Vegan condoms are a ethically and environmentally friendly alternative to traditional condoms.
