Aspen Bark Powdered Extract, Water Soluble Preservative

The Aspen, also known as the Quaking Aspen, is a tall, deciduous tree that is native to North America. The tree has a slender truck that can reach heights of up to 80 feet. The beautiful, smooth, white bark is rich in natural salicylates, a compound that acts as a potent natural antimicrobial. Salicylates are thought to help defend and protect aspen trees against the invasion of parasites.

As the media continues to focus its attention on the risks of parabens, formaldehyde releasers, and other synthesized preservatives, product formulators and manufacturers are facing the growing challenge of procuring natural alternatives that provide suitable broad-spectrum protection.

Praan Naturals is pleased to offer manufacturers and formulators a range of premium quality natural preservatives, including Aspen Bark Powdered Extract.

Aspen Bark Powdered Extract helps to resist microbial contamination and control microbial growth while simultaneously offering nutritive skin conditioning benefits.

The specialized process used to manufacture Aspen Bark Powdered Extract isolates the antimicrobial salicylate content so that the extract provides a standardized salicylate content range of 54.0-60.0%.

All formulations should be challenge tested by a qualified laboratory to ensure that each batch is properly preserved. The method of production, the specific components of the formulation, the environment in which the batch is formulated and the method of packaging all play a crucial role in the resulting shelf life of a batch. Therefore, we cannot guarantee your results when incorporating natural preservatives into your formulations. Only lab challenge testing can determine how and if a preservative is achieving the desired results.
