Abstract: Antimony dithiocarbamate is known to provide extreme pressure (EP) protection in lubricating compositions, such as grease. However, there is a desire to reduce the amount of antimony used in such compositions, while still maintaining acceptable EP performance.

To counteract the corrosive effects of the SbDTC and ammonium dithiocarbamate composition, it has been found that compounds containing a carboxylic acid group are effective in avoiding copper corrosion.
