Degradable chelants having sulfonate groups, uses and compositions thereof

摘要

New compounds are represented by Formula I: <IMAGE> and salts and complexes thereof; wherein R is an alkyl group having at least one -SO3H and at least one -OH; each R' is independently selected from hydrogen, an unsubstituted or inertly substituted alkyl group, an alkyl group substituted with a carbonyl group, with a carboxylic acid, salt or complexed carboxyl group, or an alkoxy group; R'' is hydroxyalkyl and x+y+z=3 and are good chelants. The compounds are also biodegradable and are particularly useful in hard surface cleaners.
