  • Patent number: 3954858
    Abstract: There are disclosed herein novel sequestrant builders for use in detergent compositions having the general formula: ##EQU1## wherein R.sub.1 is selected from the group consisting of H, an alkyl group having 1 to 12 carbon atoms, a hydroxylalkyl group having 1 to 4 carbon atoms, and a COOM group; n is zero or 1; when n is 1, R.sub.2 and R.sub.3 are selected from the group consisting of H, CH.sub.3 and CH.sub.2 COOM; when n is zero a double bond is present between C' and C"; X is COOM, OSO.sub.3 M or SO.sub.3 M; a is zero, 1 or 2; b is zero or 1; Z is selected from the group consisting of O, S, NH, NR.sub.4 wherein R.sub.4 is an alkyl group or hydroxyalkyl group having 1 to 4 carbon atoms provided that when Z is O, a must be zero, X must be COOM and R.sub.1 cannot be H when R.sub.2 and R.sub.3 are both H and b is zero; M is selected from the group consisting of H, alkali metal, ammonium and substituted ammonium cations.
