ABSTRACT
Natural extracts have played an important role since ancient times. Egyptian hieroglyphs over 3000 years old [1] offer formulas showing how treatment products were prepared with extracts from plants. For quite some time natural materials were the only possible raw materials available in cosmetic formulations. The very prosperous development of synthetic chemistry and manufacturing, which started around the beginning of the century, has led to a dramatic increase in materials of synthetic origin and with highly targeted functionality.
