Improve the performance of cosmetic products
Problem: The cosmetic industry is always looking for innovative solutions in order to improve products’s performances. For example, for hair dyes the aim is to identify new treatments that allow to obtain brighter colours and longer duration compared to dyes currently available on the market.
Solution: A long-lasting colour is obtained by anchoring hair dyes to keratines. This anchorage is strengthened using coadjutors or “activators” for dyes, Crossing ACLs can act as “activators”.
In the presence of a formulation containing specific ACLs, preliminary tests showed that there is an improvement in the resistance of colour after washing cycles and brighter colours can be obtained with the same amount of dyes.
