Mixing Sunflower Oil with Green Tea Extract Powder or Herbal Powder

Regarding your question about mixing Sunflower Oil with green tea extract powder or herbal powder for a facial oil, you do not need an emulsifier.

An emulsifier is used to mix oil and water together to form a stable blend (like a cream or lotion). When you mix oil (like Sunflower Oil) with a powder (like Pure-EGCG™ Green Tea Extract or other herbal powders), the powder particles will disperse within the oil, creating a suspension. The powder will not dissolve, and it may settle over time.

Therefore, you can mix the oil and powder directly. It is recommended to shake the mixture well before each use to ensure the powder is evenly distributed in the oil.

If you were considering the liquid form of green tea extract, such as Hi-EGCG™ Green Tea Extract, please note that its description indicates it is water-soluble and best used in formulations containing water (like gels, serums, lotions, or creams). Mixing a water-soluble liquid extract into pure oil would not result in a stable blend and would likely separate.

In summary:

• Mixing oil + powder: No emulsifier needed. It will form a suspension (shake before use).
• Mixing oil + water (or water-based liquid extract) (+/- powder): An emulsifier is needed to combine the oil and water phases.
