Claim:
1. An oil-in-water nanoemulsion which consists of up to 40 volume % of an oil phase comprising at least 50 volume % of a triglyceride having a fatty acid chain length of 12 carbon atoms or greater; a hydrophilic non-ionic surfactant having a hydrophilic-lipophilic balance (HLB) greater than 7; and an aqueous phase; optionally one or more additional oils; a co-solvent selected from the group consisting of methanol, ethanol, propanol and butanol, wherein the amount of col-solvent is 0.1 to 70 wt %; optionally a co-surfactant selected from a sorbitan fatty acid ester, phospholipid, sodium stearoyl lactylate and calcium stearoyl lactylate; and optionally an additive selected from a stabiliser, antioxidant, preservative, buffering agent, charge inducing agent, weighting agent and protein in which the oil droplets of the nanoemulsion have an intensity average size of less than 100 nm, the ratio of surfactant to oil is less than 1:1 and the nanoemulsion retains its structure upon dilution and/or acidification.
