Nanosilver synthesis was carried out by a one-step chemical reduction. Ascorbic acid and gelatin were used as reducing agent of silver ions and stabilizing factor of nanoparticles. Obtained nanosilver suspensions were characterized by monomodal particle size distribution with their average size of 5–125 nm.

Valuable properties of nanosilver caused that it is one of the most desirable nanomateials. Its biocidal properties make it is applied in many areas including cosmetics, medicine, medical engineering, construction, agriculture industry and others. Due to the fact that the preparation of nanosilver brings many benefits, many ways of its acquiring have been developed. In addition to the known physical and chemical methods, in recent times, environmentally friendly methods are increasingly important. A review of methods for the preparation of nanosilver using plant extracts has been described. Keywords: nanosilver, green chemistry, plant extracts

The use of renewable sources for synthesis of cosmetics ingredients

The use of renewable sources for synthesis of cosmetics ingredients. Feliczak -Guzik A., Jagodzi ńska K., KROMA A., Nowak I. Please cite as: CHEMIK 2012, 66, 2, 123-128 Depletion of non-renewable sources of energy and materials has stimulated the search for new ways to generate chemicals, energy and materials using renewable sources. The best renewable resource is the one that can be supplied in a relatively short period of time and whose amount is in principle unlimited. Such substrates come from plants, animals or ecosystems and can be regenerated through sustainable management.
