Abstract Of The Disclosure Heavy duty built synthetic organic detergent compositions, which are especially useful for washing laundry in wash water of medium hardness, include either anionic or nonionic synthetic organic detergents or mixtures thereof and a polyacetal carboxylate builder of lower molecular weight, i.e., 3,000 to 6,000. The detergent(s) perferably is/are a sulfated higher fatty alcohol ethoxylate and/or a condensation product of ethylene oxide and a higher fatty alcohol, and the polyacetal carboxylate is a sodium carboxylate. The compositions are especially useful for cold water washing of laundry and in such washing processes they are found to be superior in soil and stain removal to similar compositions wherein the polyacetal carboxylate is of higher molecular weight. They are also superior in such performance to control compositions in which sodium tripolyphosphate is present instead of the polyacetal carboxylate builder. Also within the invention are washing processes in which the described compositions or essential detersive and builder components thereof are employed.
