    Abstract: The present invention relates to industrial gear lubricating composi- tions that include a specific class of substituted triazoles, where the substituted triazole includes at least one hydrocarbyl group linked to one of the nitrogen atoms in the triazole ring. Such compositions pro- vide surprisingly good seal compatibility compared to compositions with other triazoles and/or alternative additives.

    Abstract: This invention relates to improved grease compositions comprising a major amount of an oil based simple metal soap thickened base grease and a minor amount of at least one phosphorus and boron containing composition, said phosphorus and boron containing composition prepared by reacting a combination of (A) at least one boron compound and (B) at least one phospholipid. In one embodiment, the phosphorus and boron containing composition is present in amounts sufficient to improve the extreme pressure, antiwear and lubricity properties of the base grease. In another embodiment the phosphorus and boron containing composition is present in amounts sufficient to increase the dropping point of the base grease, as determined by ASTM procedure D-2265, by at least 20.degree.C.
