Rose Oil Gum and Old Man Smell

Kracie is selling gum aimed at older men who don't want to smell like older men. I looked up the main ingredient, geraniol, and it is the main component of rose oil and is used in some perfumes, various flavorings and even tobacco, but I am not sure why it is supposed to have a specially good effect for masking old man odor or "otoko kusai" (オトコくさい).
As I remember, another company isolated the main ingredient responsible for old man smell, but I am not sure what product resulted from that discovery.
