This invention relates to N-alkylated anthranilic acid derivative and their use in lubricants, such as engine oils, as TBN boosters. The invention particularly relates to compositions that deliver an ash-free base to a lubricant in the form of a basic amine additive, without adversely impacting seal compatibility and/or degradation, and methods thereof.
