Solubility of Astaxanthin Liquid (Stabilized, Crystal Clear)
Question
I noticed conflicting information regarding the solubility of Astaxanthin Liquid (Stabilized, Crystal Clear). The product description states it is water-soluble, but the technical section indicates it is oil-soluble. Which phase should this specific stabilized liquid be incorporated into (water phase or oil phase) for cosmetic formulation?
Answer
The product Astaxanthin Liquid (Stabilized, Crystal Clear) (Product ID: 127221) is designed to be water-soluble (or water-dispersible).
The confusion you noted is valid and stems from the difference between the raw material and the finished product:
- Pure Astaxanthin: The natural carotenoid Astaxanthin is inherently oil-soluble.
- Astaxanthin Liquid (Stabilized, Crystal Clear): This specific product is a stabilized liquid formulation that has been specially processed to be clear and compatible with the water phase of cosmetic formulas. The product description explicitly states it is a "clear, water-soluble, stable liquid."
Therefore, for your formulations, you should treat Astaxanthin Liquid (Stabilized, Crystal Clear) as a water-soluble ingredient. We will review and correct the technical section of the product page to resolve the inconsistency.
