Design of an Emulgel‐Type Cosmetic with Antioxidant Activity Using Active Essential Oil Microcapsules of Thyme (Thymus vulgaris L.), Cinnamon (Cinnamomum verum J.), and Clove (Eugenia caryophyllata T.)

open access: yesInternational Journal of Polymer Science, Volume 2018, Issue 1, 2018., 2018
Essential oils (EO) are complex mixtures of biosynthesized chemicals basically by plants, which provide them their characteristic aroma. Many have biologically recognized activities as antioxidants and anti‐inflammatory among others, and many of them are employed as cosmetic actives. Very often, these properties are not fully exploited because of their

A multiscale approach to evaluate the effect of different extraction and pre‐treatment methodologies on physicochemical properties of cashew (Anacardium occidentale L.) nut shell liquid

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 2, Page 266-275, February 2026.
Abstract BACKGROUND Cashew nutshell liquid (CNSL) is an agro‐industrial residue from cashew production that has gained relevance due to its possibilities to generate valuable by‐products. Although lab‐scale CNSL extraction has been studied in terms of yield and energy efficiency, the effect of industrial‐scale extraction and nut pre‐treatment methods ...
