  Description du sujet:
• Nowadays a huge demand for solid cosmetics is observed in the cosmetic market in order to limit bulky packaging containing aqueous dispersions and tend towards the "zero waste". In the same time, multifunctional products able to be both make-up and skincare products are very attractive since they allow simplified formulations. Furthermore, there is a groundswell of interest for bio-based products as alternative to mineral ones such as talc, mica, silica, widely used as additives to improve the dispersibility and spreadability of cosmetics on the skin as well as to absorb sweat and sebum.
• In this context, we aimed to rationalize talc or silicates-containing products in face compacts and to develop new powdered compacts containing a limited number of ingredients in the formulation and a high level of biopolymers (polysaccharides) having similar properties (serving as bulky agent, preventing caking, assuring the flowability and dispersibility during the manufacturing process, compaction behavior, improving skin feeling, adhesiveness to the skin, sebum absorption, skin hydration, light or full skin coverage) as inorganic additives. Then the project concerns the development of a bio-based simple face-compact powder formulation containing an active agent.
