Information about your blend of Argan Oil, Bakuchiol, and DMI

Here are the answers to your questions about mixing Argan Oil, Bakuchiol, and Dimethyl Isosorbide (DMI):

1. Preservative: For an oil-based mixture like this, which does not contain water, traditional antimicrobial preservatives are generally not necessary because microbes require water to grow. However, oils can still oxidize and become rancid over time. Bakuchiol is known to have antioxidant properties and can help stabilize natural oils, potentially extending the shelf life of the Argan Oil.
2. Shelf life: The shelf life of the mixture will depend heavily on storage conditions. To maximize the shelf life, store the mixture in a tightly sealed, opaque container, away from direct sunlight and heat. Refrigeration is recommended for long-term storage. Bakuchiol may help improve the stability of the Argan Oil.
3. Mixing Method: Yes, you can mix these three ingredients by simply combining them in a bottle and shaking. Since all three are liquids and compatible with each other (Bakuchiol and DMI dissolve/disperse in oil), shaking will be sufficient to create a homogeneous mixture quickly. It should not take long, just a brief period of shaking until the mixture appears uniform.
4. Odor: Argan Oil (Deodorized) has had its typical nutty smell removed. However, Dimethyl Isosorbide (DMI) has a characteristic ether-like smell, and Bakuchiol has its own natural scent. Therefore, the resulting mixture will likely have a noticeable odor from the DMI and Bakuchiol. You can add fragrance to the mixture to mask these odors if desired.
