It is sometimes called Brazil Wax or Palm Wax.
The Food and Drug Administration (FDA) includes carnauba wax in its list of substances considered 'Generally Recognized as Safe' (GRAS) for direct addition to food.
It is also PCPC listed (Personal Care products Council).
Although it is part of the emulsifying system, its primary function is to significantly increase water resistance, thus enabling the avoidance of synthetic polymers used in most sunscreens for which water resistance is claimed.
