Propolis and Beeswax in Cosmetics: A Market Survey and Literature Review on Their Relationship and Role in Allergic Contact Dermatitis

open access: yesContact Dermatitis, Volume 94, Issue 5, Page 494-503, May 2026.
Propolis is rarely used in conventional cosmetics within the EU, and such products are therefore unlikely to be significant sources of exposure for patients with positive patch test reactions to propolis. There is no evidence that small amounts of propolis in white beeswax (cera alba) in cosmetics can trigger allergic contact dermatitis in individuals ...

Trophic Diversity in Aquatic Food Webs Along a Tropical Coastal River Continuum in West‐Central Africa

open access: yesFreshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT In the wet Afrotropics, information on trophic diversity and resource use in freshwaters is extremely limited. Here we used stable isotope ratios (δ13C, δ15N) from food webs along the continuum of a coastal river in the Republic of the Congo to examine seasonal and spatial patterns of trophic diversity.

Isoeugenol-based novel potent antioxidants: Synthesis and reactivity

open access: yesEuropean Journal of Medicinal Chemistry, 2011
We are attempting to develop the novel phenolic synthetic antioxidants aimed at retarding the effects of free radicals and oxidants. The phenolic compounds (7-12) were synthesized by Friedel-Crafts alkylation of isoeugenol (1) and phenol derivatives (2-6) and their structures were determined by spectroscopic methods.
