Question

Can fragrance be mixed directly with oil? Does this type of oil become rancid? If so, how can rancidity be prevented? For 120ml of oil, how much fragrance should be added?

Answer

Mixing Fragrance Oil with Avocado Oil

Yes, you can mix fragrance oil directly with Avocado Oil (Refined). Fragrance oils are generally miscible with carrier oils like Avocado Oil.

Regarding rancidity, natural oils like Avocado Oil can indeed become rancid over time due to oxidation. To help prevent or slow down this process, you can add antioxidants to your oil blend. Some options include:

  • Vitamin E (Tocopheryl Acetate): A stable form of Vitamin E. It helps protect against oxidation but has lower efficiency compared to other types.
  • Vitamin E (dl-alpha tocopherol): Another form of Vitamin E with moderate efficiency, higher than Tocopheryl Acetate, but has a shorter lifespan.
  • Rosemary Oleoresin Extract (ROE): A highly effective natural antioxidant, especially when used with Vitamin E. Note that it has a dark color and distinct smell.
  • Protec™ OX: A highly effective synthetic antioxidant.
  • Protec™ UV: A synthetic UV absorber that protects ingredients from UV light damage, which can contribute to degradation.
  • Protec™ SQ: A singlet state quencher that helps reduce oxidation caused by UV light. It is effective but has a dark yellow color.

The amount of fragrance oil to add to 120ml of Avocado Oil depends entirely on your desired scent strength. There is no fixed amount; you should add gradually and test until you achieve the fragrance intensity you prefer.
