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

Contact Dermatitis, EarlyView.
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 ...

The dose makes the poison: have “field realistic” rates of exposure of bees to neonicotinoid insecticides been overestimated in laboratory studies? [PDF]

, 2014
Recent laboratory based studies have demonstrated adverse sub-lethal effects of neonicotinoid insecticides on honey bees and bumble bees, and these studies have been influential in leading to a European Union moratorium on the use of three neonicotinoids,
