Formulating Guidelines:
Can be incorporated into the aqueous phase.**Additional Considerations: At a high concentration, FSS White Willow Bark Extract Powder may affect the viscosity of gum-thickened systems. FSS White Willow Bark Extract Powder contains natural salicylates which will contribute to the total salicylates/salicylic acid present in a finished product. In pigmented formulations containing iron oxide, the natural salicylates present in FSS White Willow Bark Extract Powder may form colored ferrosalicylic complexes with iron oxide, reducing the total amount of salicylates present over time.
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.
