Candelilla Wax comes from the Candelilla shrub, which grows in northern Mexico. It is completely vegetable-based and therefore 100% vegan. It is often used as a substitute for beeswax, as they have very similar properties.
Quoted from (edited for relevance, emphasis added) eHow.com:
"For those who wish to use a wax emulsifier, but want a plant-based or allergy-free alternative, candelilla wax is a solid choice. While most waxes are best suited for lighter formulations, candelilla wax works well in thicker, heavier, water-in-oil formulations. Lotions made with candelilla wax sit on the skin longer without breaking down, which lends them to formulas for drier or sensitive skin that need more protection."
