Formulating 3% Bakuchiol with Natural Oils and the need for EDTA
Question
Can Bakuchiol 3% be mixed with any natural oils, such as Sea Buckthorn (Fruit) Oil, Rose Hip Oil, and Avena sativa (Oat) Oil, to reach 100% of the formulation? And is it true that Disodium EDTA is not necessary in this formulation?
Answer
Regarding your question about formulating with Pure-Bakuchiol™ (Natural Retinol, 99% Pure, USA) at 3% concentration:
Yes, you can mix 3% Pure-Bakuchiol™ with natural oils such as Sea Buckthorn (Fruit) Oil, Rose Hip Oil, and Avena sativa (Oat) Extract (Oil Soluble) to make up 100% of your formula. These oils are suitable for creating an oil-based serum or blend.
However, regarding Disodium EDTA, the product description for Pure-Bakuchiol™ specifically recommends adding a chelating agent like Disodium EDTA (at 0.1%) or Phytic Acid for stability. This is because Bakuchiol is sensitive to metal ions that might be present in the formula, even in an oil base. Therefore, it is not unnecessary; it is recommended for optimal stability.
Please note that the recommended usage rate for Pure-Bakuchiol™ in the product description is 0.5-1%. Using it at 3% is higher than the recommended concentration.
For maximum efficiency and skin penetration, the product description also recommends including Dimethyl Isosorbide (DMI) at 2-3% in your formulation.
