ABSTRACT
The numerous examples of multifunctional personal care products in today’s marketplace clearly illustrate the relevance of the concept of multifunctionality to modern cosmetic science. Effects, efficacies, and performances that were never considered to be associated are now being combined-for instance: color and moisture, UV blocking and suppleness. In theory, the number of combinations of efficacies is infinite. On paper, multifunctionality can be easily invented, but technically, it may be extremely difficult to find the chemicals that allow the cosmetic scientist to achieve these demanding requests of consumers and marketers.
