This invention relates to a process for preparing a sulfurized composition comprising the steps of preparing a mixture comprising (a) a fatty acid or ester, and (b) an olefin having from about 6 to about 30 carbon atoms, and reacting the mixture with sulfur and hydrogen sulfide in the presence of a catalyst and under superatmospheric pressure, wherein the mixture contains from about 10 to about 90 parts by weight of (a) and from about 10 parts to about 80 parts by weight of (b), and wherein from about 10% to about 70% of the sulfur is from hydrogen sulfide. The invention also relates to a sulfur composition comprising a hydrocarbyl sulfide, wherein from about 20% to about 90% of the hydrocarbyl groups are derived from a fatty acid or ester and from about 10% to about 80% of the hydrocarbyl groups are derived from an olefin having from about 6 to about 30 carbon atoms, wherein the hydrocarbyl sulfide contains from about 8% to about 15% sulfur, and has a neat ASTM color of less than about 4.5.
