All cosmetic-grade ultramarines are lab-manufacturered from sulphur.  This product will release hydrogen sulphide in an acid-base reaction, causing a "rotten egg" odor.  This reaction may occur if the pH is under 6 on the pH scale.  Generally, this only occurs with the ultramarine blue shades (not the pinks or violets).

Ultarmarines can be used in face makeup, and eye makeup, soaps and lotions. Ultramarines and oxides can be blended together to give a wide range of colours. For soap making Blue Ultramarine can be added after the lye and fats are blended, use at about 1 teaspoon per 2.27 kg (5 lbs) soap. Iron oxides are inorganic and will not bleed. Do not use in lipsticks. Not recommended for nail lacquers.
