Such NPs involve some problems including that lipid NPs should be evaluated in terms of size, stability, safety and efficient drug loading and release, and polymeric NPs should be evaluated in terms of size, surface charge, safety, biocompatibility and especially degradation kinetics and byproducts. The oral absorption rate is independent of the solubility of the calcium salt and is therefore applicable to calcium contained in calcium oxide. Further functions of calcium include, e. The first method is limited due to lack of availability and appearance of such suspending media. The effects of manganese doping on UVA absorption and free radical generation of microfine titanium dioxide and its consequences for the photostability of UVA absorbing organic sunscreen components. Hence, particle size needs to be maintained in a well-defined range and must be evenly distributed. Their enhancer effect was attributed to their positioning and remaining in the skin layers.
