NANOMATERIALS IN COSMETIC PREPARATIONS

This review determines various nanomaterial based cosmeceuticals. And glance on the properties, types, techniques used for preparation of nanomaterials, their advantages & disadvantages and various marketed products. Cosmeceuticals are fastest growing segment in the personal care industry and their use has increased drastically over the past years. The nanocosmeceuticals are mainly used in the application of cosmetics in managing conditions of wrinkling, dehydrated & inelastic skin associated with aging and dispersed hyperpigmentation, with the use of nanosized materials. The nanosized materials are nano emulsions, liposomes, nanosomes, dendrimers, nanocapsules and solid lipid nano particles. These nanosized materials have an advantage in increasing skin penetration and they release the active substances in a controlled and sustained manner. They have a higher stability; can be site specic targeting and high entrapment efcacy. Researchers have indicated concern regarding the impact of increased use of nanosized materials in cosmeceuticals and there are some possibilities of nanosized material can penetrate into the skin and cause health hazards.
