With more consumers entering middle age than ever before, personal care products are evolving to meet changing market needs. In response to this trend, formulators look for innovative ways to enhance the appearance of skin and encourage a more youthful, healthy appearance. Use of botanical extracts and other potentially unstable cosmetic actives continues to rise. At the same time, competition in the marketplace favors products with novel, appealing sensory attributes such as fragrance, a component that can also be unstable.
Ingredient instability drives the need for delivery systems that combine performance with cost efficiency. Because delivery technologies differ widely, selection of an appropriate system depends on individual formulation parameters as well as the expertise of the delivery system provider.
