All cosmetic-grade ultramarines are lab-manufactured from sulphur. As a result the product can develop a “sulphur” or “rotten egg” odour in various formulating conditions (typically it is related to the pH of the product where if you bring the product under 6 on the pH scale you will begin to notice an odour).
