| titleOfInvention | PROCESS TO PRODUCE EMULSIONS OF SMALL LOW PRESSURE DROPS, NANOEMULSION |
| abstract | Procedure to prepare nanoemulsions of oil in water. The oil phase contains oil selected from the group consisting of triglyceride oil and / or petrolatum and a C₈ to C₁₈ fatty acid to be added during preparation; and the aqueous phase contains specific N-acyl derivatives of the amino carboxylic acid as the primary emulsifier. Claim 1: A process for preparing a nanoemulsion composition, characterized in that it comprises: a) an internal phase comprising (i) 40 to 75% by weight of a total nanoemulsion composition of oils selected from the group consisting of triglycerides, petrolatum and mixtures thereof, where the melting point of the petrolatum is 30 to 60 ° C; (ii) 1.1 to 8% by weight nanoemulsion of a C₈ to C₁₈ fatty acid; and b) an external aqueous phase comprising 2 to 15% by weight (as active) of the total nanoemulsion composition of a surfactant or surfactants that are N-acyl derivatives of an amino acid salt; wherein the surfactant of (b) comprises 50% or more of all the surfactant present in said external aqueous phase; wherein the average volume drop diameter of (a) is from 20 to 600 nanometers, wherein said procedure comprises: 1) adding the fatty acid C₈ to C₁₈ of component (a) (ii) to the oil of (a) ( i); 2) heating the oil phase (a) to a sufficient temperature such that all the compounds melt; and 3) heating the aqueous phase to a temperature range of 45 to 75 ° C; and 4) simultaneously pumping the heated aqueous and oily phases through a sonolator or a conventional homogenizer using a process pressure of 500 pounds per square inch (psi) or less. |
