I want to know what vitamin A Retinyl Acetate powder can be dissolved in the cool down phase of the cream? Just on the web page it says to mix in water. heat resistant But I'm afraid that vitamin A will be sensitive to heat. I'm not sure.
Hello Retinal Acetate is soluble in oils (and various organic solvents), not soluble in water. Mix, dissolve in oil in the formulation first. If it's difficult to melt, you can use warm heat (50-60 degrees) to help melt.
