Claim 1
Independent Claim
40 words
A method of inhibiting or preventing the growth of bacteria and fungi in an aqueous composition subject to spoilage thereby which comprises incorporating in said composition an effective amount of a methyl, ethyl, propyl or butyl ester of α-chloro-β-aminocrotonic acid.
Claim 2
Independent Claim
40 words
A method of inhibiting or preventing the growth of bacteria and fungi in an aqueous composition subject to spoilage thereby which comprises incorporating in said composition an effective amount of a methyl, ethyl, propyl or butyl ester of α-chloro-β-aminocrotonic acid.
Claim 3
Dependent Claim
