Polymers in cosmetics are used to deliver desired attributes to skin and hair. Precisely constructed block and graft copolymers widen the range of available mechanical properties and compatibilities. Stimuli responsive hydrophobic polymers can be triggered to become hydrophilic by changes in their environment and this can confer waterproof properties at low temperature and easy water removal at higher temperatures. Transfer-resistant cosmetics can be possible due to silicone resins. The control of rheology properties in cosmetics gradually continue to be easy with copolymers. Durability of colors and fragrances for rinse-off products can be enhanced by delivery systems from complex coacervates. Polymeric anti-microbials promise product preservation while minimizing the concern of skin permeation. This article reviews recent trends in the use of polymers in cosmetics.
