Biological detergents are cleaning products that contain enzymes, which are proteins that help break down stains and dirt. These enzymes target specific types of stains, such as proteins, fats, and carbohydrates, making them effective for removing tough marks from fabrics. They work best in warm water, where the enzymes can function optimally. Unlike non-biological detergents, which rely on chemical agents for cleaning, biological detergents are often considered more environmentally friendly. They can be effective at lower temperatures, which may save energy and reduce carbon footprints. However, some people may be sensitive to the enzymes used in these products.
