Abstract
A perfumed detergent tablet comprises a clay mineral compound and a heavy metal ion sequestrant. The clay mineral helps disperse the tablet in aqueous media and acts as a fabric softener for laundered fabrics. The perfume is free of Schiff bases, such as those formed from anthranilates and aldehydes, which can discolor the clay.
