Practical formulation guide
Usage level::
- 1 to 3 % in hair products.
- 3 to 5 % in body products.
- 5 to 10 % in facial products.
HIGHER CONCENTRATIONS SHOW NO NEGATIVE EFFECTS.
How to use and incorporate: Aqueous, glycolic or glycerin extracts: add to the water phase or during cool-down (below 40 °C/104 °F). Oil extracts: add to the oil phase or during cool-down. Powdered extracts: first dissolve or disperse in water or glycerin. Adjust the pH at the end.
Formulation tips:
- Extracts contribute color, odor and microbial load: use a broad-spectrum preservative system and run a microbial challenge test on the final formula.
- They may precipitate in the cold or over time; filter or shake before use and check that the color or clarity of the finished product does not change.
- 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.
Compatibility: Aqueous and glycolic extracts are compatible with gels, toners, emulsions and surfactant bases; oil extracts with oils and emulsions. Some tannins and flavonoids darken in the presence of iron or at alkaline pH.
Storage: The optimal storage temperature for the extract is 4–18 °C/39–64 °F; 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.
Technical information for formulators: This sheet describes industrial uses of the raw material in the development of cosmetic products. It is not an efficacy claim for any finished product. The person responsible for the formulation must validate the concentration, compatibility and claims of their product in accordance with applicable regulations.
