Powder detergents typically contain salts such as sodium sulphate and washing soda, which avoid clumping and assist in dissolving oil and grime, as well as oxidising agents for light bleaching effects.

Liquid detergents are mostly water-based and contain surfactants (both ionic and non-ionic), water softeners, and preservatives to maintain stability and inhibit microbial development.

Some detergents contain enzymes, which are proteins that break down specific stains, such as lipase for fats and protease for proteins; nevertheless, they are sensitive to high temperatures, which can damage their efficiency.

While liquid detergents provide advantages such as direct stain removal, they may lack peroxides, which help fight germs and mould in washing machines, potentially allowing biofilms to grow.
