摘要:Improved oil-in-water emulsions are provided and a method for theirmanufacture. In particular, the emulsions comprise a means to control delivery of oil-soluble or water-soluble actives in a core comprising a liquid oil or gel oil continuousphase, which actives can be delivered with improved deposition to surfaces such as, inparticular, the skin, gastro-intestinal tract and that defined by the oral cavity. Theemulsions are also noted for their improved stability. The stable emulsion comprises astable droplet dispersed in an aqueous phase, the stable droplet comprising a core, afirst inner layer coating the core, and a second outer layer coating the first inner layer,wherein the core comprises at least a liquid oil or gel oil continuous phase, wherein thefirst inner layer comprises at least one at least partially solid uncharged emulsifier and atleast one anionic or cationic or zwitterionic emulsifier, the second outer layer comprises afirst polycation or first polyanion or first polyzwitterion of opposing charge to the firstinner layer, and wherein the at least partially solid uncharged emulsifier forms a solutionin the aqueous phase or the liquid oil phase or the gel oil phase at temperatures greaterthan room temperature, preferably greater than 40, more preferably greater than 50,even more preferably greater than 60 degrees centigrade. The invention also provides a
product selected from the group consisting of a food product, a home care product, apersonal care product and a pharmaceutical product, wherein each product comprisesemulsion of the invention.
