Question about Pineapple Fragrance Ingredient (Pineapple Heptadienone, Pharaone 10%) Properties and Scent

Regarding Pineapple Heptadienone, Pharaone 10% from bescent:

• The active ingredient is dissolved in Dipropylene glycol (DPG) to achieve the 10% concentration.
• If you use this 10% solution and dissolve it further in alcohol, the DPG from the 10% solution will be present. Your calculation of approximately 9% DPG in the final mixture (if the 10% solution is 10% of the final volume/weight) is plausible based on the product description. However, having DPG in the perfume base does not make it sticky or oily.
• This product is a single molecule extracted from pineapple, not a natural-like pineapple blend. It provides only one tone or aspect of the pineapple scent.
• Using this single ingredient alone will not smell exactly like a complete pineapple. A full pineapple scent is composed of several molecules blended together.
• If you wish to create a pineapple scent blend, other important components include Allyl cyclohexyl propionate, Allyl Caproate, and Allyl Amyl Glycolate, in addition to Pineapple Heptadienone/Pharaone. Adding a fruit base can also help complete the scent.
