Beeswax
Cera Alba, commonly known as beeswax, is a natural solid wax produced by honey bees to construct their honeycomb. It consists primarily of myricyl palmitate, cerotic acid and esters, and some high-carbon paraffins. In cosmetics, it functions as an emollient, thickening/viscosity-controlling agent, emulsifier, and film-forming ingredient. It is especially common in lip balms, lipsticks, and other anhydrous formulations.
Beeswax acts as an emollient that helps soften and condition the skin, and as a thickening agent that gives body and structure to formulations. Its film-forming properties help create a protective layer on the skin surface, supporting moisture retention.
Not suitable for vegans or those with bee-related allergies. No photo-sensitivity or notable active-interaction concerns are mentioned in the source.
