Abstract

|
Natural safflower oleosomes are small (1{sim}3{mu}m) spherical shaped "reservoir", inside which the seed stores triglycerides for use as a future energy source. The surface of the oleosome is covered with a high molecular weight (20{sim}24 KDa) oleosin protein which has been demonstrated to have emulsification properties. Traditionally, oleosomes from oil bearing seeds such as safflower were simply crushed to liberate the oil within. Our patented DermaSphere technology allows for the isolation of oleosomes in the intact state. Once isolated, these materials can be used in skin care formulations to deliver the emolliency, occlusivity, and anti-oxidant effects typically associated with safflower oil. However, because of the presence of the emulsifying oleosin protein covering the spherical oil body, oleosomes have self-emulsification property as well as can emulsify other oil phase in typical oil-in-water (O/W) emulsion. The oleosomes can literally serve as the entire non-active portion of the oil phase of a typical skin care product. Most importantly, natural oleosomes can be loaded with other oil-soluble active materials and can therefore be used as delivery systems for improved cosmetic efficacies. Oleosomes can be loaded with various actives, such as fragrances, vitamins, inset repellents, and UV chromophores. The loaded oleosomes can be utilized to either protect the active ingredients within the formulation itself or to allow for control release of those actives over time.
