Aqueous emulsifier package with anionic surfactant for fuel emulsion

An emulsifier package for emulsifying a fuel and water, consisting of comprising:

• an anionic surfactant selected from the group consisting of sulfates and sulfonates, consisting of comprising
• at least one sulfate selected from C6-22 alkyl sulfates, and
• at least one alkyl ether sulfate of the general formula R—O—(CH2CH2O)mSO3,
• in which R is a linear or branched alkyl and/or alkenyl radical having 6 to 22 carbon atoms, and m is a number from 1 to 10, and
• wherein the sulfonate is selected from di-(C8-10) alkyl sulfosuccinates,
• at least two nonionic surfactants which are alkoxylates, wherein the alkoxylates are selected from alkoxylated alkanols of the formula (I),
• Re—O-(AO)m—Rf (I)
• in which
• Re is straight-chain or branched alkyl or alkylene with from 1 to 32 carbon atoms,
• AO is an ethylene oxide radical, propylene oxide radical, butylene oxide radical, pentylene oxide radical, styrene oxide radical, or a mixture of the abovementioned radicals, in random or block sequence,
• m is a number from 1 to 100, and
• Rf is hydrogen or alkyl with from 1 to 4 carbon atoms, and
• water,
• and optionally one or more optional ingredients selected from the group consisting of organic solvents, aliphatic, cycloaliphatic, or aromatic mono-, di-, or polycarboxylic acids with at least 6 carbon atoms, sulfonates, sulfosuccinates, quaternary ammonium surfactants, carrier oils, cold flow improvers, lubricity improvers, corrosion inhibitors, dehazers, antifoams, cetane number improvers, combustion improvers, antioxidants, stabilizers, antistats, metallocenes, metal deactivators, and dyes,
• wherein said fuel is at least one fuel selected from the group consisting of diesel fuel and a marine fuel obtained from petroleum distillation as a distillate or a residue.
