Effect of Perfumes on the Viscosity of Surfactant Systems
It is well-known that perfumes can affect the viscosity of bubble bath or shampoo formulations. Usually they have a thinning effect, but they can also cause a viscosity increase. The effect and its magnitude will vary with perfume type and also with the product formulation. Small changes in the latter can cause large changes in a perfume's effect on the viscosity.

Implicit Olfaction: Effect On Use Of Fragrance In Functional Products
Recent research shows that fragrances may be smelled and remembered implicitly, that is without awareness of their presence. This finding helps to explain well-known but poorly understood facts about fragrance in functional consumer products: namely, their widely-shared meanings within markets and their halo effect. Implicit olfaction has consequences for fragrance selection and testing, as well as for product labeling and advertising.
