Multiple economic, legislative and customer pressures are forcing an unprecedented level of change in chemical manufacturing and the design of chemical products. The authors examine the drivers for change and opportunities across the product lifecycle for green and sustainable chemistry including the use of renewable resources, cleaner synthesis methods and greener products.

The present work describes a cosmetic technology based on a newer formulating concept—cream in powder form. The final formulation can be created by two different technical processes to produce either water- or oil-based cosmetics. In each case, the proper selection of ingredients determines the stability of the finished products.

A new technology has been developed for the production of o/w phase inversion concentration (PIC) emulsions with a very fine particle size and excellent storage stability. The concept is based on non-ethoxylated emulsifiers and can be easily used for the preparation of impregnating lotions for cosmetic wet wipes.
