Suggested Use Levels:
•Facial Masks: 1.0% – 10.0% •Cleansers / Washes: 0.5% – 5.0% •Soaps / Bars: 1.0% – 8.0% •Exfoliating Products: 0.5% – 5.0%

pH Stability in Formulations:
3 to 10 under normal cosmetic use conditions
Formulating Guidelines:
May be incorporated into the water phase, oil phase, or cool-down phase depending on formulation type and desired dispersion characteristics. We generally recommend pre-dispersing into a small portion of water, glycerin, oil, or humectant for improved incorporation and uniformity. Adequate mixing/shear is recommended to minimize agglomeration.
Odor:
Characteristic
Shelf Life:
12 months from date of manufacture.
Storage:
Store in a dry place at temperatures not exceeding 32°C. Based on stability studies, the optimum storage temperature for maximization of shelf life is 23 - 25°C. However, it may be stored at temperatures between 16 and 32°C if such specific temperature control is not available. Do not freeze.
