In the 1940s, synthetic sponges were invented and patented by the DuPont Company. They were made primarily with sodium sulphate, hemp fiber, and cellulose derived from wood pulp; and secondarily with bleach, chemical softeners, and dye. In 1952, the synthetic sponge-making process was sold to General Mills. Since then, synthetic sponges have successfully competed with natural sponges for most common household uses.
