Jojoba oil is a natural stabilizer for different oils, and fragrances are composed of volatile substances which evaporate over time, so Jojoba Desert (JD) used the services of a professional laboratory to test if JD Jojoba Oil could stabilize fragrance materials by deceleration of their evaporation rate.
Testing for Fragrance
During the first stage of the experiment, two samples of pure oils were tested—JD Jojoba Oil and Sweet Almond oil—combined with 5% of Geranium essential oil, test subjects evaluated the odor intensity during a three-hour timeframe. Both oils started with the same odor intensity. At the end of the experiment, the odor intensity in JD Jojoba Oil sample was higher than the odor intensity in the Almond oil, showing the evaporation rate of the essential oil from the JD Jojoba Oil sample was slower.
In order to see whether this phenomenon would behave the same in a formula, the lab tested a sample of basic aqua cream formulation with both oils and Geranium essential oil as a perfume. After the cream application, panelists were asked to rank the loss in odor intensity for each sample. After three hours, the essential oil evaporated in both products, resulting in the loss of odor intensity; however, in the case of formulation based on JD Jojoba Oil, the evaporation rate was slower.
“Through these experiments, we proved that JD Jojoba oil can stabilize the scent and ensure slow release of odor by the sensorial approach in pure oil and in a basic cream formulation,” said Dr. Anna Aharoni, R&D manager at Jojoba Desert. “This performance benefit of JD Jojoba Oil can be valuable in each cosmetic product that contain some amount of oil. When the product is formulated with JD Jojoba Oil, the odor can last longer, even if highly volatile perfumes are used.”
JD Jojoba Oil can help manufacturers and consumers enjoy clean beauty without having to compromise on performance or on long-lasting scent.
