The Sweetness in Chanel Allure Homme Sport Eau Extreme

What ingredient gives off that subtle addicting sweetness 1-2 hours after applying Chanel Allure Homme Sport Eau Extreme?

I’m inclined to believe it’s the Tonka Bean, and if so, was wondering if Montale Arabian’s Tonka would be a good addition to my collection as the sweetness in CAHSEE is addicting and I cannot stop smelling myself after applying it.
