ABSTRACT:
A powder laundry detergent has improved solubility in the laundering solution by incorporating an acidulant that, in its acid form, is sparingly soluble in water and, in its salt form, is soluble in water. In particular, the acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 0.7% by weight at 25.degree. C. and in a salt form are soluble in water at least in an amount of about 15% by weight at 25.degree. C. A method of improving the solubility of a powder detergent includes admixing an acidulant in the powder detergent where the acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 0.7% by weight at 25.degree. C. and in a salt form are soluble in water at least in an amount of about 15% by weight at 25.degree. C.
