Mixing Natural Oils with SPF Protect Ultra II

Yes, natural oils such as Safflower Oil, Grape Seed Oil, and Avocado Oil can be combined with SPF Protect Ultra II. SPF Protect Ultra II is an oil-soluble sunscreen ingredient.

However, simply mixing the oils directly with SPF Protect Ultra II is not recommended if you intend to create a stable and effective sunscreen product. To ensure the sunscreen actives are properly dispersed and the sun protection factor (SPF) is maintained, SPF Protect Ultra II should be incorporated into a properly formulated product, typically an emulsion (like a cream or lotion) that uses emulsifiers.

In a standard formulation process, SPF Protect Ultra II would be heated to 70-80°C and mixed into the oil phase of your formula. The natural oils you mentioned can be part of this oil phase. This oil phase is then combined with a water phase using appropriate emulsifiers to create a stable product that provides reliable sun protection.

Mixing without proper formulation techniques and emulsifiers can lead to an unstable mixture where the sunscreen actives are not evenly distributed, potentially reducing the effectiveness of the sun protection.
