PhytoCide Aspen Bark Extract
CAS No. 90083-05-9
PhytoCide Aspen Bark Extract is extracted from the bark of the American Aspen tree, also known as the Quaking or Trembling Aspen. The bark of the Aspen tree is rich in salicylates that may function as the plant’s natural defense mechanism against invading parasites. Historically, the salicylates in Aspen bark have also be used for medicinal purposes. Medicinal barks have been used as analgesics and to reduce fevers for centuries.
The Natural salicylates in Aspen Bark have been isolated by Active Micro Technologies and standardized between 54.0 - 60% in PhytoCide Aspen Bark Extract Powder. This powder has been found to have a useful activity as an antimicrobial in cosmetic and personal care products. Initial efficacy testing has shown it to be effective at inhibiting the growth of E. coli, S. aureus, B. subtilis, P. aeuruginosa, yeast and mold. Additionally, it may also impart a smooth feel to the skin.
