Ultramarine Blue

Cosmetic Grade. USA approved for use: Eyes, Face, NOT Lips. EU approved for use: Lips, Eyes, Face. Recommended for nail polish (pre-wet with alcohol) and soap making (stable and non-bleeding). 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).
