This active agent consists of a combination of natural lethicins and phospholipids with different levels of phosphatidylcholine. Its uses as a co-emulsifier, humectant or active agent make lecithin a good choice to improve all kinds of formulae with unique sensorial and natural gains. The phospholipids present in it perform their own biological role. As natural ingredients virtually identical to skin, the have great affinity with its tissue and, thus, are easily diffused throught the cutaneous layers. They are important sources of fatty acids which are essential for keeping the skin soft, once they form a protective layer on its surface, avoiding water loss.
