Oil-in-water emulsions

An oil-in-water emulsion comprising an oil phase dispersed in an aqueous phase, the oil-in-water emulsion comprising:

• from 0.05 to 0.6 wt % of a surfactant selected from the group consisting of fatty alkyl amines, ethoxylated fatty alkylamines, ethoxylated fatty alkyl monoamines, methylated fatty alkyl monoamines, methylated fatty alkyl amines, and quaternary fatty alkyl amines, or a combination thereof;
• one or more organic acids selected from the group consisting of:
• methanesulfonic acid, formic acid, acetic acid, citric acid, benzoic acid, p-toluenesulfonic acid, and combinations thereof;
• up to 50 wt % hydrocarbon residue;
• from about 0.5 to about 70 wt % of an alcohol selected from the group consisting of:
• C1 to C6 mono or di hydric alcohols;
• and
• from 30 to 70 wt % glycerol;
• wherein the oil-in-water emulsion has the following characteristics:
• an average droplet size (D[4,3]) of from 3 to 15 μm;
• less than 3 wt % of the droplets have a particle size of greater than 125 μm;
• and
• a dynamic viscosity of up to 500 mPas at 50° C. and 100 s−1, wherein viscosity is measured on a Malvern Kinexus™ instrument.
