Buckthorn Oil Dispersible Powdered Extract is derived from the brightly colored berries of Rhamnus Petiolaris, a species of buckthorn. Buckthorn Extract is known in the textile industry for the range of yellow hues it produces when used as a botanical dye. In the personal care industry, it may be used as a natural dye in soaps and as a beneficial herbal extract in skin care formulations.
Buckthorn Oil Dispersible Powdered Extract is a natural source of beneficial phenols. It may be used in soaps, creams, lotions, balms, bath salts, scrubs and other formulations to incorporate the phytochemicals and herbal benefits of the extract. We recommend doing several test batches to find the ideal usage rate for your product, as the extract will impart a characteristic hue to your formulation and may limit your usage rate.*
For Soapmaking Applications:
Several factors, including the base color of your recipe, will affect the final color achieved when using this extract.
The final result will also depend on which phase the extract is added to. Therefore, we recommend experimenting by creating different one-pound test batches so that you can compare the results achieved by adding the extract directly to the oil phase, steeping the extract in the lye solution and adding the extract to the combined phases at trace.
In our one-pound test batch, we found that adding 1 level tablespoon of dry extract directly to the warm oil phase yielded a bar that cured to a mottled off-white and yellow hue after four weeks. Our uncolored control batch was a light off-white shade after curing for four weeks.
*Important Usage Note: While this extract may be used for its herbal benefits in personal care products such as creams, lotions and balms, the FDA does not allow its intentional use as a color additive in such products. It may be used as a natural botanical dye in soaps as the FDA does not regulate the manufacturing or labeling of soap. A soap is defined by the FDA as a product intended for cleansing the skin. It must be made from a combination of alkali (lye) and fats/oils, and it cannot contain detergent agents.
*Shelf life begins on the date of manufacture and is defined as the average reasonable shelf life of an ingredient
when it is stored and handled properly.
