TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The 8C or greater fatty acid sorbitan ester is a 8-22C fatty acid sorbitan ester, a saturated or unsaturated tallow fatty acid sorbitan ester and/or a saturated or unsaturated coconut fatty acid sorbitan ester. The 8C or greater fatty acid sorbitan ester has: a viscosity of at least 15000 centipoises (cP) at 25 degrees C, preferably 15000-50000 cP at 25 degrees C; type A Shore Durometer hardness of at least about 0.5, preferably 0.5-94 and where the friction modifier composition has a type A Shore Durometer hardness 0.5-94, preferably a type A Shore Durometer hardness of at least 10. The 8C or greater fatty acid sorbitan ester is of formula (I). The fatty acid sorbitan ester is present at 1-50000 part per million, the weight percentages are based on the total weight of the friction modifier composition. The composition further comprises: at least one additional additive (5-95 wt.%), which is tartrates, citrates, alkanolamides, alkanols, aminic antioxidants and/or phenolic antioxidants, preferably 12-14C acetal of tartrate, diethyl tartrate, diisopropyl tartrate, 8-22C alkanolamide, lauryl diethanolamide, lauryl diethanolamide alkanol, alkylated diphenyl amine, N,N'-di-sec-butyl-p-phenylenediamine, N-phenyl-N-alkyl-p-phenylene diamine, N,N'-di-isopropyl -p-phenylenediamine, 2,6-di-tert-butyl-phenol, 2,4-di-methyl-6-tert-butyl-phenol, 2-methyl-6-tert-butyl-phenol, 2-tert-butyl-4-methyl-phenol or 2,6-dimethyl-4-tert-butyl-phenol. The composition has a coefficient of friction of less than about 0.09 at 130 degrees C, as measured by a Cameron Plint TE 77 high frequency friction test.n = 6-28 (preferably 14).Preferred Process: In the process, the fatty acid sorbitan ester is released into the lubricant at a rate of 0.0025-0.15 grams per minute, preferably at a rate not greater than 0.5 grams per minute. EXAMPLE - Excell 100 HC (RTM: Base stock) was blended with composition (500 ppm) of tallow sorbitan ester (TSE) and HXL 7121 (RTM: Alkyl tartrate) to give the lubricant composition.
