Which of the following are examples of base oils with a strong smell?

• A. Olive oil, Wheat germ, Sesame seed, and Avocado oil
• B. Almond oil, Grapeseed oil, Sunflower oil, and Hazelnut oil
• C. Coconut oil, Olive oil, Sesame oil, and Jojoba oil
• D. Peach kernel oil, Soy oil, Sesame seed oil, and Olive oil

Answer: (A)

Odor strength varies a lot among carrier oils, and some carry a noticeable aroma that can influence a blend’s overall scent. Olive oil, wheat germ oil, sesame seed oil, and avocado oil are known for their more pronounced scents. Olive oil has a robust, fruity-olive aroma, especially in higher grades, which can linger in a mix. Wheat germ oil brings a rich, nutty, roasted note and is quite potent despite being used in small amounts. Sesame seed oil has a distinctly toasted, nutty fragrance that stands out. Avocado oil often has a deeper green, fatty aroma that can be more noticeable than many other carriers. In contrast, oils like almond, grapeseed, sunflower, and hazelnut are typically lighter or near-neutral in aroma, making them less likely to influence the blend’s scent.
