Oil-in-water nanoemulsions comprising oil globules with an average size of less than 150 nm and comprising at least one oil, at least one amphiphilc lipid, and at least one polyethylene glycol (PEG) derivative chosen from PEG esters and PEG ethers chosen from compounds of formula (I): R.sub.1 --(O--CH.sub.2 --CH.sub.2).sub.n --OR.sub.2 (I) in which: R.sub.1 is chosen from linear and branched, saturated and unsaturated alkyl groups comprising from 8 to 30 carbon atoms and linear and branched, saturated and unsaturated acyl groups comprising from 8 to 30 carbon atoms, R.sub.2 is chosen from a hydrogen atom, linear and branched, saturated and unsaturated alkyl groups comprising from 1 to 30 carbon atoms, and linear and branched, saturated and unsaturated acyl groups comprising from 1 to 30 carbon atoms, and n is a number ranging from 80 to 350. Processes comprising such oil-in-water nanoemulsions.

Nanoemulsions aceite/agua que abarcan glóbulos del aceite con un tamaño medio de menos de 150 nm y que abarcan por lo menos un aceite, por lo menos un lípido del amphiphilc, y por lo menos un derivado del glicol de polietileno (CLAVIJA) elegido de los ésteres de la CLAVIJA y de los éteres de la CLAVIJA elegidos de compuestos del fórmula (i): R.sub.1 -- (O -- CH.sub.2 -- CH.sub.2).sub.n -- OR.sub.2 (i) en el cual: R.sub.1 se elige de los grupos alkyl lineares y ramificados, saturados y no saturados que abarcan a partir 8 a 30 átomos de carbón y de los grupos lineares y ramificados, saturados y no saturados del acyl que abarcan a partir 8 a 30 átomos de carbón, R.sub.2 se elige de grupos alkyl lineares y ramificados, saturados y no saturados de un átomo del hidrógeno, que abarcan a partir 1 a 30 átomos de carbón, y de grupos lineares y ramificados, saturados y no saturados del acyl que abarcan a partir 1 a 30 átomos de carbón, y n es un número que se extiende a partir del 80 a 350.
