Using ODA-White Plus™ and Sym-White™ in Oil-Based Formulations
Based on the information for ODA-White Plus™ and Phenylethyl Resorcinol (Sym-White™), here's how they can be incorporated into formulations:
Phenylethyl Resorcinol (Sym-White™): This ingredient is oil-soluble. While it can dissolve in oil, product information suggests it is typically used in cream or lotion formulations, which contain both oil and water phases with an emulsifier. The stability of Phenylethyl Resorcinol is also dependent on the pH of the final product, ideally between 4-5, which is easier to achieve and maintain in an emulsion system.
ODA-White Plus™: This ingredient is an oil itself and is soluble in oil. However, for use in cream or lotion formulations, the product information explicitly states that while the formula doesn't necessarily need additional oil, it must contain an oil-in-water emulsifier. This indicates that to create a stable and effective product with ODA-White Plus™, an emulsion system (containing both oil and water phases with an emulsifier) is required.
Conclusion:
While both ODA-White Plus™ and Phenylethyl Resorcinol can dissolve in oil, formulating a stable and effective product containing these ingredients typically requires an emulsifier and often a water phase to create a cream or lotion. A purely oil-based formula might not be suitable for achieving the best stability and performance, especially for ODA-White Plus™ which requires an emulsifier for incorporation into common cosmetic bases like creams and lotions.
