A salicylate is disclosed, which has detergent and anti-oxidant
properties, for use as a metal based detergent additive. An alkyl
salicylic acid is derived from the alkylation of salicylic acid with
styrene. The neutralization and subsequent overbasing of neutral salt
results in an alkaline detergent, such as calcium or magnesium
salicylate. The resulting detergent is a salicylic acid having
multi-styrenated chains, which provide oil solubility. A method for
making such a detergent is also disclosed.
