Oil and Fragrance Separation Issue

The separation observed in your mixture of Mineral Oil, Sweet Almond Oil, and White Musk fragrance occurs because the fragrance is likely not fully soluble or compatible with the specific blend of these carrier oils at the concentration used (1%). Fragrances are complex mixtures, and their solubility can vary greatly depending on the carrier oils.

Traditional emulsifiers are used to mix oil and water to create a stable emulsion. Since your mixture is primarily oil-based (Mineral Oil and Sweet Almond Oil) with a fragrance, a traditional emulsifier designed for oil-in-water or water-in-oil emulsions is generally not the correct solution.

What you might need is a solubilizer or a co-solvent that can help the fragrance integrate better into the oil blend. While solubilizers like Flora Solve™ Clear and Ultra Solve™ are typically used to dissolve oils and fragrances into water or water-based formulas, they function by improving compatibility between different types of molecules.

Based on the products available, Flora Solve™ Clear (Fragrance Solubilizer) and Ultra Solve™ are potential candidates that might help improve the compatibility of the White Musk fragrance within your oil blend, even though their primary use is for dissolving fragrances into water. Ultra Solve™ is described as a highly effective solvent for various oils and fragrances.

You could try adding a small amount of either Flora Solve™ Clear or Ultra Solve™ to your oil and fragrance mixture to see if it helps prevent separation. Start with a low percentage and observe the results. Please note that success is not guaranteed as these are typically used for oil-in-water systems, but they are the most relevant products available for improving fragrance solubility.

Always test any modifications in a small batch first.
