Solving Fragrance Separation in Anhydrous Body Oil Formulations

The separation of fragrance in an anhydrous body oil formula containing Mineral Oil (Paraffinum Liquidum) Very Light (15cst) and natural oils usually occurs due to the difference in polarity. Fragrance oils often contain polar components that do not blend well with non-polar oils like Mineral Oil.

To solve this issue and prevent separation, you can use "Coupling Agents" or "Solubilizers" that are compatible with oil systems:

Recommended Ingredients:

1. Isopropyl Myristate (Deodorized): This is a highly effective ester that acts as a coupling agent. It helps bridge the gap between the non-polar mineral oil and the more polar fragrance components. It also helps reduce the greasiness of the formula and improves skin absorption.
   • Usage: 3-10% of the total formula.
2. LipidSoft™ C1215 (C12-15 alkyl benzoate): An excellent solvent for fragrances and sunscreens. It is very stable and helps clarify the oil mixture while providing a light, silky skin feel.
   • Usage: 3-10% of the total formula.
3. Flora Solve™ Clear (Fragrance Solubilizer): While often used for water-based formulas, it can also be used to help harmonize and stabilize fragrances within oil systems due to its unique solubility properties.

Recommended Mixing Technique:

To ensure maximum stability, do not add the fragrance directly into the large batch of oil. Instead:

1. Mix the Fragrance with the coupling agent (such as Isopropyl Myristate or LipidSoft™ C1215) in a separate container first.
2. Stir until the mixture is completely clear.
3. Slowly add this mixture into your main oil base (Mineral Oil and natural oils) while stirring continuously.

If the formula remains cloudy or continues to separate, you may need to increase the ratio of the coupling agent relative to the fragrance.
