- wherein
- A is an optionally substituted phenyl, naphthalene, indole, purine, pyridine, quinoline, isoquinoline or pyrimidine;
- and
- Z has a structure of moiety A or moiety B:
- wherein
- X is —O—, —N(R10)—, or —OC(O)—;
- n is an integer from 0 to 10;
- R6 and R9 are independently hydrogen, alkyl, or aryl;
- R7 is —(CH2)z-O—R11;
- R8 is independently hydrogen, alkyl, or aryl;
- R10 is hydrogen, alkyl, or Z;
- R11 is hydrogen or alkyl;
- m is independently an integer from 3 to 20;
- and
- z is an integer from 1 to 10;
- and the cleaning composition has a pH of 7 or less.
