TL;DR: Despite the fact that microencapsulation of EOs is a very promising and extremely attractive application area for cosmetic industry, further basic research needs to be carried out, for a better understanding of the biofunctional activities of microencapped EOs and its release modulation, as well as the effects of others cosmetic ingredients and the storage time in the microparticles properties.
Abstract: Nowadays, the consumers around the world are increasingly focused on health and beauty. The renewed consumer interest in natural cosmetic products creates the demand for new products and reformulated others with botanical and functional ingredients. In cosmetic products, essential oils (EOs) play a major role as fragrance ingredients. They can optimize its proprieties and preservation, as well as the marketing image of the final product. Microencapsulation of EOs can protect and prevent the loss of volatile aromatic ingredients and improve the controlled release and stability of this core materials. The importance of EOs for cosmetic industry and its microencapsulation was reviewed in this study. Also a briefly introduction about the preparation of microparticles was presented. Some of the most important and usual microencapsulation techniques of EOs, as well as the conventional encapsulating agents, were discussed. Despite the fact that microencapsulation of EOs is a very promising and extremely attractive application area for cosmetic industry, further basic research needs to be carried out, for a better understanding of the biofunctional activities of microencapsulated EOs and its release modulation, as well as the effects of others cosmetic ingredients and the storage time in the microparticles properties.

TL;DR: A clear and significant improvement was visible in the endoscopic and self-assessment ratings after rehabilitation by isolated voice therapy, and despite possible anatomical and physiological aging changes in the phonatory system, age did not compromise the successful rate obtained by voice therapy.
Abstract: Objective:To use a multidimensional assessment to analyze potential influence of “aging” in the functional outcomes achieved by a group of patients with recent onset of unilateral vocal fold paraly...

Journal ArticleDOI
TL;DR: Important aspects of antibiotic pollution in fresh waters are highlighted: that concentrations of antibiotics in the environment are substantial, that micro-organisms are susceptible to this, that bacteria can evolve resistance in the environments, and that antibiotic pollution affects natural food webs while interacting with other stressors; which taken together poses a number of challenges for environmental scientists.
