Safflower oleosomes isolated in the form of a naturally occurring emulsion can be useful to the cosmetics marketplace to deliver the emolliency, occlusivity and antioxidant effects without the need for other emulsifiers. In addition, safflower oleosomes can be used as the nonactive portion of the oil phase of a typical cosmetic formulation.

In the presented study, researchers suggest that acrylates/aminoacrylates/C10-30 alkyl PEG-20 itaconate copolymer serves to stabilize hydroxypropyl starch phosphate polymer in surfactant systems, and also enables hydroxypropyl starch phosphate polymer to further build viscosity.

Novel silicone-based vesicles can encapsulate and subsequently release a variety of cosmetic actives--both oil-soluble and water-soluble. This article discusses the silicone polyethers used to develop these vesicles and the methods used to evaluate both the silicone polyethers and the vesicles. One study describes the use of these vesicles to encapsulate retinyl palmitate.

Hydrolytic instability of esters in cosmetic products can be reduced, compared to that of standard straight chain esters, by using non-hydrolyzable esters synthesized from a diol reaction sequence. Two commercial dimer diol di-esters, given as examples, enable stable formulations at extremes of pH.

Nanoemulsions prepared and stabilized with hydrophobically modified inulin as the surfactant require much less surfactant than nanoemulsions prepared and stabilized using conventional surfactants such as alcohol ethoxylate because they have a reduced Ostwald ripening rate.
