Abstract:
1. A particulate composition comprising; a) 5 to 50% of at least one phosphatidyl choline component b) 5 to 90% of at least one diacyl glycerol component, at least one tocopherol, or mixtures thereof, and c) 1 to 40% of at least one non-ionic stabilising amphiphile consisting essentially of surfactants having a molecular weight below 8000 amu, wherein all parts are by weight relative to the sum of the weights of a+b+c and wherein the composition comprises particles of at least one non-lamellar phase structure or forms particles of at least one non-lamellar phase structure when contacted with an aqueous fluid; wherein, when contacted with an aqueous fluid to form particles having a non-lamellar phase structure, no more than 1% of particles have a particle size outside the range of 0.05-1.5 μm; and wherein the compositions are essentially stable in terms of phase behaviour, particle size and particle size distribution for at least 3 months.
