Since minerals are in ionic forms in aqueous phase (like deep sea water), it is very hard to incorporate concentrated minerals in gel like cosmetic formulations which are generally composed of carbomer or acrylates polymer. In this study, we invented a salt-resistant network formulation made of silicon copolyol. It was found that the network formulation traps minerals (especially from marine) in a mesh-like silicone copolyol structure. Since the mineral-containing formulation makes a very thin film on the skin, minerals could be easily absorbed into stratum corneum. In 6 weeks in vivo test, it was found that the novel mineral formulation increased the amounts of amino acids, major components of natural moisturizing factors (NMFs), as well as levels of minerals. It was also found that the moisture contents and the brightness of the skin increased.
