Solubility and Dispersion of Water-Dispersible Vitamin A Acetate
คำถาม
I'm confused about how to dissolve Vitamin A Acetate. I tried dissolving it in oil, but it didn't seem to dissolve well, perhaps needing heat. When I tried dissolving it in water, it seemed to dissolve better, resulting in a cloudy liquid. Could you clarify the correct way to dissolve or mix this type of Vitamin A?

Solubility of Vitamin A Acetate (Retinyl Acetate)
Generally, Retinyl Acetate is an oil-soluble form of Vitamin A.
However, based on the product information found, the specific type you might be using, Vitamin A Acetate (Retinyl Acetate, Water-Dispersible, 325,000 IU/g), is a special form developed to be dispersible in water.
- Dissolving in Oil: This Water-Dispersible form is not designed to dissolve directly in oil. Therefore, when you tried dissolving it in oil, it did not dissolve, or perhaps required high heat, which would still be dispersion rather than true dissolution.
- Dissolving in Water: This type of product can "disperse" well in water, making it appear to dissolve better than in oil. However, it is actually dispersing into small particles in the water, resulting in a cloudy liquid, which matches your observation.
Conclusion: The correct way to dissolve/mix Vitamin A Acetate (Retinyl Acetate, Water-Dispersible, 325,000 IU/g) is to disperse it in water, not dissolve it in oil.
