Dissolving Oil-Soluble Vitamins in Clear Gel/Serum

Question

I am formulating a clear gel or serum and want to incorporate oil-soluble vitamins, specifically Retinyl Palmitate and Vitamin E at 5%. How can I dissolve these oil-soluble ingredients to maintain clarity in a water-based gel/serum? I have heard about using Ethoxydiglycol; is it suitable for this purpose?

Answer

Dissolving Oil-Soluble Vitamins in Clear Gel/Serum

Regarding your question about dissolving oil-soluble Retinyl Palmitate and Vitamin E in a clear gel or serum, here is the information:

  • Retinyl Palmitate and Vitamin E Solubility: Both Retinyl Palmitate (Vitamin A Palmitate) and Vitamin E (Tocopheryl Acetate) are oil-soluble ingredients. They do not dissolve directly in water.

  • Creating a Clear Gel/Serum: To incorporate oil-soluble ingredients into a clear, water-based gel or serum, you need to use a solubilizer. A suitable product for this purpose is Flora Solve Clear.

  • How Flora Solve Clear Works: Flora Solve Clear is designed to combine oils (like your vitamins) with water or water-based gels (created with a thickener like Pro Polymer) to form a clear microemulsion. This allows the oil phase to be stably dispersed in the water phase without making the product cloudy like a traditional emulsion (cream or lotion).

  • Usage Ratio for Flora Solve Clear: You should mix the oil-soluble ingredients (Vitamin A and Vitamin E) with Flora Solve Clear first before adding this mixture to the water phase. The recommended starting ratio is 2-3 parts of Flora Solve Clear to 1 part of the total oil mixture (Vitamin A + Vitamin E). You can test this ratio and increase the amount of Flora Solve Clear up to 5 parts if needed to achieve a clear solution when mixed with the water phase. If the mixture turns cloudy upon adding to water, it means you need more Flora Solve Clear.

  • Ethoxydiglycol: Ethoxydiglycol is a solvent and carrier, but it is not suitable for dissolving oil into water to create a clear, stable solution in the way that a solubilizer like Flora Solve Clear does. It cannot act as an emulsifier in this context.

  • Note on Vitamin E Concentration: Using Vitamin E at a concentration of 5% is quite high and may result in a sticky feeling on the skin.

In summary, to create a clear gel or serum with Retinyl Palmitate and Vitamin E, you should use Flora Solve Clear to solubilize the vitamins before adding them to a gel base made with a thickener like Pro Polymer. Ethoxydiglycol is not an appropriate substitute for this purpose.
