We consider that scientific research has been behind the development of various branches of chemistry (organic, analytical, electrochemical...), for nearly two centuries. Among the activities rich in scientific and innovative potential, there is one concerning cosmetology. There are thousands of chemical recipes that cover the field of beauty and health. This does not prevent the emergence of new, more specialized branches, thanks to the social and economic changes that the world is currently experiencing. In our article, we propose a new technique for the preparation of various cosmetic solutions by the process of soft chemistry. The process of soft chemistry is based on the technique of preparation of solutions and chemical complexes, at low temperature and in a less humid and aerated environment. The main characteristic method of soft chemistry is the one known as the soil gel process.
Our work consists in preparing new natural organo-molecules by ground-gel which will be used as a basis in cosmetic compounds intended for the care of the human body in general. The basis of these compounds consists of colored plant extracts, whose main ability is to focus photons and therefore to allow the dispersion of light within various chemical matrices.
Using poly (vinyl alcohol) (PVA) with highly hydrophilic properties as a membrane material and poly(ethylene glycol) (PEG) as an additive, as well as the Betacyanin dye we prepared ultrafiltration membranes (UF) PVA/Betacyanin with good anti dirt properties, disinfectant and vital for the skin, by a soil-gel method. PVA/Betacyanin UF membranes have been characterized by models of X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and static contact angle of water measurement. The morphology and permeation performance of the PVA/Betacyanin membranes varied with different Betacyanin loads and PEG content.
