Odor Science

ODORGO founder Şebnem Oğuz has a saying: "If you can smell it, it's inside you."

This section explains the science behind that sentence. How an odor forms, how the nose and brain process it, why it clings to things, and why some methods work while others don't. All of it sourced, none of it exaggerated.

Pages

• 1. What is odor and how does the brain perceive it?

  The three conditions a molecule has to meet to become a smell, the olfactory epithelium and its roughly 400 receptors, the signal's route to the brain, and why smell hits memory directly.

• 2. Why do odors cling to things and why do they come back?

  Adsorption, which surfaces hold odor and why, why heat and humidity bring an odor back, and the right cleaning order.

• 3. Masking or neutralization?

  The real difference between room sprays, odor trappers, odor absorbers and odor eliminators; an honest look at ozone, ultraviolet and enzyme products.

• 4. How does ODORGO work?

  Attracts, binds, neutralizes: the mechanism, the formula, which format suits which product, and what the product does not do.

  Odor eliminator, odor trapper, odor absorber, deodorizer: 15 terms with their definitions.
