Abstract
An industrial fluid additive composition comprises one or more sequestering agents one or more compounds of formula (A): (A) wherein R1 and R2 are independently selected from substituted hydrocarbyl moieties containing from 1 to 10 carbon atoms or unsubstituted hydrocarbyl moieties containing from 1 to 10 carbon atoms.
Claims18
An industrial fluid additive composition comprising:
- one or more sequestering agents comprising one or more phosphonate moieties, present in an amount of at least 5% by weight of the composition, and
- one or more compounds of formula (A):
- present in amounts in the range of from 10% to 50% by weight of the composition;
- wherein the compound of formula (A) contains from 5 to 12 carbon atoms;
- wherein R1 and R2 are independently selected from substituted hydrocarbyl moieties containing from 1 to 5 carbon atoms or unsubstituted hydrocarbyl moieties containing from 1 to 5 carbon atoms;
- and
- wherein the composition does not comprise a biocide.
