Practical formulation guide
Usage level: Depending on the application.
How to use and incorporate: Add to the oil phase of the formula. Oils rich in polyunsaturated fatty acids (linoleic, linolenic) are heat-sensitive: add them during cool-down (below 40 °C/104 °F) or heat them as briefly as possible. In anhydrous products (body oils, balms) blend cold or warm.
Formulation tips:
- Oil rich in polyunsaturated fatty acids, very sensitive to oxidation: add during cool-down, protect with tocopherol and pack in an opaque bottle.
- Add an antioxidant such as tocopherol (vitamin E) at 0.05–0.5 % to delay rancidity and extend shelf life.
- Combine light, fast-absorbing oils with heavier oils to adjust the skin feel; dry oils work well in facial serums and heavier oils in balms and products for dry skin.
- Before scaling up, make a pilot batch and run a stability test (cycles at 4 / 25 / 45 °C/39 / 77 / 113 °F for 4 weeks, checking odor, color, pH, viscosity and separation) in the final packaging.
Storage: The optimal storage temperature for the extract is between 4 and 18 °C/39 and 64 °F, protected from light. If precipitates form during storage, shake until reconstituted before adding to your formulation.
Precautions: Once the container is opened, handle the product with care to avoid secondary microbial contamination. None in particular for the user. Handling: Add as the last ingredient of the preparation at temperatures below 50 °C/122 °F; dissolving it before use is recommended.
