Abstract

Crystal growth of cloquintocet mexyl hydrate is inhibited by polymeric carboxylate compounds.

Claims

1. A method of reducing crystal growth of cloquintocet mexyl hydrate formed when a composition containing cloquintocet mexyl is exposed to water which comprises incorporating into the composition containing cloquintocet mexyl a crystal-growth inhibiting amount of a polymeric carboxylate having a molecular weight of about 500 to about 70,000 grams per mole.

2. The method of claim 1 in which the weight ratio of polymeric carboxylate to cloquintocet mexyl is from about 1:

100 to about 1;

0.001.

3. The method of claim 2 in which the weight ratio of polymeric carboxylate to cloquintocet mexyl is from about 1:

10 to about 1;

0.1.

4. The method of claim 1 in which the polymeric carboxylate is an alkali metal salt of a polyacrylic or polymethacrylic acid.

5. The method of claim 1 in which the polymeric carboxylate is the sodium salt of a copolymer of maleic anhydride and 2,4,4-trimethylpentene (CAS 37199-81-8).
