Summary:PCT No. PCT/EP94/04057 Sec. 371 Date May 20, 1996 Sec. 102(e) Date May 20, 1996 PCT Filed Dec. 6, 1994 PCT Pub. No. WO95/16020 PCT Pub. Date Jun. 15, 1995The use of polyaspartic acid prepared by polycondensation of aspartic acid in the presence of phosphoric acid in a molar ratio of from 1:0.05 to 1:10 at temperatures of at least 120 DEG C. to give polysuccinimide, and subsequent hydrolysis of the polysuccinimide with bases to give at least partially neutralized polyaspartic acid, as additive to detergents and cleaners in amounts of from 0.1 to 10% by weight, and detergents and cleaners which contain polyaspartic acids prepared in the presence of phosphoric acid.
