  • Patent number: 11141362
    Abstract: The present invention relates to novel oil-in-water nanoemulsions. The oil phase contains oil selected from the group consisting of triglyceride oil and/or petrolatum as well as C8 to C18 fatty acid; and the aqueous phase contains specific N-acyl derivatives having specific counterions of amino acid salt as emulsifier, glycerol, and water. When (i) there is defined ratio of glycerol to water; (ii) specific counterion for amino acid surfactant and (iii) fatty acid in oil phase. Nanoemulsions are processed in a one-step process yielding droplets of size 20 to 400 nm. In one embodiment, droplets of size 20 to 400 nm can be made using rotor-stator device (in one-step process) and in the absence of pressure based homogenizer. This saves in energy and cost. Compositions prepared according to this processes are also contemplated.
