Willow Bark Liquid Extract

Willow Bark Extract is a source of natural salicylic acid-like ingredients which has been shown to contribute effects similar to those seen from synthetic salicylic acid with none of the drawbacks associated with its use, primarily irritation. As such, it is a safe way to get the benefits of a ß-hydroxy acid.

Salicylic acid, when used in cosmetic formulations at 0.5% to 1%, enhances skin cell turnover by promoting exfoliation, resulting in a general improvement in the appearance of the skin and a smoothing effect with accompanying reduction of fine lines and wrinkles. Also known for its antimicrobial properties, it can be useful as a remedy for problem skin conditions.

In vitro tests have shown Willow Bark Extract to have activity against Staphylococcus aureus and Propionibacterium acnes, the two strains of bacteria implicated in the formation of acne, as such it may prove useful in targeted facial cleaners, toners and lotion formulas.

In addition, challenge testing has shown that, in cosmetic formulations, of varying degrees of complexity,  Willow Bark Extract , when present in concentrations of 2.5 - 5%, contributes to the preservative efficacy of formulas even when no other synthetic chemical preservatives are used. It has proven efficacy against gram positive, gram negative bacteria, yeast, and mold.

The choice of preservatives for personal care formulations should be carefully considered. This is especially true when using natural antimicrobial and or other “mild” antimicrobial. We recommend that every formula undergo stability and microbial testing to ensure adequate preservation.
