PhytoCide Aspen Bark Extract Powder

Willow bark and aspen bark are both a source of salicin, from which salicylic acid, an aspirin-like substance, is derived. In cosmetics, extracts from these barks are amazing multitaskers that are used for their anti-inflammatory, exfoliating, and even preservative properties. Salicylic acid is in a class of medications called keratolytic agents. Topical salicylic acid treats acne by reducing swelling and redness and unplugging blocked skin pores to allow pimples to shrink. It treats other skin conditions by softening and loosening dry, scaly, or thickened skin so that it flakes off or can be removed easily.

These salicylates may be isolated from Aspen Bark and applied to cosmetic and personal care products as a natural alternative to traditional chemical preservative systems. The manufacturing method allows us to consistently isolate a salicylate content between 54.0 – 60.0%, which makes PhytoCide Aspen Bark Extract Powder an ideal antimicrobial. As an additional benefit, PhytoCide Aspen Bark Extract Powder may also impart a smooth feel to the skin.

A Double Challenge Test was completed using 2% PhytoCide Aspen Bark Extract Powder in a generic cream base formulation. Samples were inoculated with E. coli, P. aeruginosa, S. aureus, A. brasiliensis, and C. albicans. During the first 28-day incubation period, samples were periodically collected and tested for the presence of these microorganisms. Following this initial 28 days of incubation, the cream samples were then re-inoculated with the microbial cultures and sampled over an additional 28-day period. The results were over 99.99% effectiveness
