Natural waxes are sustainable materials that remain under-exploited today in cosmetics while they represent a unique starting block for many green chemistry reactions.
Moisturisation is one of the main objectives in skin care cosmetics. Moisturising properties are generally brought by glycols, mainly glycerin, and emollients such as mineral oil which are used to decrease the transepidermal water loss (TEWL). Whereas it is acceptable in temperate conditions, these solutions lead to overloaded skin and discomfort in tropical conditions.
Functionalised waxes, prepared through transesterification and polyglycerolysis of specific wax blends are efficient moisturisers and usable in a wide variety of usage conditions. These products named Acticire® (active texturising agent)1 and Emulium® Mellifera (PEG-free sensorial emulsifier)2 contain a variety of modified waxes and bring true benefits to the skin (see Table 1).
