At least one of the components comprises a sulfurized neopentyl glycol phosphate, a substituted succinimide, a reaction product of a 16C alkyl dicarboxylic acid and ammonia, a fatty amine ethoxylate, an oleamide, a dodecyl succinic acid, a pour point depressant, a combustion improver, a foam inhibitor, a cetane number improver, an adipate, a sulfurized isobutylene, an alkylthiadiazole, an alkylpolymethacrylate comprising less than 0.3% weight of unreacted monomer, an olefin copolymer or a multifunctional olefin copolymer viscosity index improver comprising less than 0.3% weight of unreacted monomer, or a polyalphaolefin. Preferred Method: The non-persistent material is determined by a biodegradation test comprising a dissolved organic carbon die-away test, a modified Organization for Economic Cooperation and Development (OECD) screening dissolved organic carbon die-away test, a carbon dioxide evolution test, a manometric respirometry test, a closed bottle test, a Japanese Ministry of International Trade and Industry (MITI) test, a Zahn-Wellens test, an activated sludge simulation test, an activated sludge respiration inhibition test, or a modified semi-continuous activated sludge test. The non-bioaccumulative material is determined by a bioconcentration factor test comprising a flow-through fish test. The bioconcentration factor test comprises a flow-through fish test. The non-toxic material is determined by a toxicity test comprising an acute toxicity for fish test, an acute toxicity for Daphnia test, or an algal inhibition test. Preferred Condition: The non-bioaccumulative material has bioconcentration factor test result below 2000. The non-toxic material is devoid of a toxic effect at an aqueous concentration below 0.01 mg/L on a toxicity test. A non-persistent material is a material having an acceptable score on a biodegradation test comprising a half-life in marine water of less than 60 days; a half-life in fresh or estuarine water of less than 40 days; a half-life in marine sediment of less than 180 days; a half-life in fresh or estuarine water sediment of less than 120 days; and/or a half-life in soil of less than 120 days.
