f you are interested in Aroma-chology you will enjoy spending sometime on the (SOSI) website.Even if you don’t exactly know what Aroma-chology is I think you will find the website facinating. You can learn more about them here.

Aroma-Chology was developed by the Sense of Smell Institute in the 1980’s. It is defined as, “a collection of scientific data under controlled conditions to study the interrelationship of psychology and fragrance technology to transmit a variety of specific feelings and enhance behavior through the olfactory experience. Aroma-Chology seeks to establish the positive effects of aromas on human behavior that are verifiable through reproducible scientific experiments. Aroma-Chology deals only with the psychological effects achieved through the use of ambient odors that stimulate the olfactory pathways to the brain.”

From the Sense of Smell Institute you can learn about research done by the SOSI, use their virtual library, go to various scientific links, refer to the glossary of olifaction, check out their publications, go to Smell 101 and one of my favorite sections Fun Facts.

Here are a few Fun Facts from the SOSI:

Everyone has his or her own unique odor-identity or “smell fingerprint.

No two people have the exact same odor-identity or “smell fingerprint” which is determined by many factors including: our genes, skin type, diet, medicine, mood state and even the weather.

The average human being is able to recognize approximately 10,000 different odors.

Our sense of smell is so powerful that when you smell skunk, you are smelling 0.000,000,000,000,071 of an ounce of scent. Dogs have about 200 million olfactory receptors. That is about 20 times the number of receptors that humans have.

It is important to understand that throughout every day and night of our lives we smell a wide variety of odors without being aware of them at all.

We go about our activities, breathing in and out, as an infinite number of chemical molecules interact subliminally with our odor receptors. Only when an odor irritates or pleases us or acts as a sudden reminder of the past do we pause to take notice.

People recall smells with a 65% accuracy after a year, while the visual recall of photos sinks to about 50% after only three months.

Our odor memories frequently have strong emotional qualities and are associated with the good or bad experiences in which they occurred. Olfaction is handled by the same part of the brain (the limbic system) that handles memories and emotions. Therefore, we often find that we can immediately recognize and respond to smells from childhood such as the smell of clean sheets, cookies baking in the oven, the smell of new books or a musty room in Grandma’s house. Very often we cannot put a name to these odors yet they have a strong emotive association even if they cannot be specifically identified.


Dene Godfrey has been involved with preservatives for cosmetics since 1981, from both technical and commercial angles and has a degree in chemistry. Dene worked for one of the largest manufacturers of parabens from 1992 – 2002, and currently works for a UK company involved in the distribution of ingredients for cosmetics, health care and food. The Boots Company, 1973 – 92, Dene spent 11 years working with bronopol, although he was also involved in the initial development of Myavert C, now known as Biovert – a well-known “non-preservative”. Latterly was responsible (as Technical Manager) for the operation of the Formulation Laboratory and the Microbiology Laboratory. As Technical Manager when at Nipa Laboratories, Dene was responsible for development and sales of new preservative products, mainly into personal care. Developed the Nipaguard range of preservatives and co-patented a preservative system based on phenoxyethanol and IPBC. In 2002, Dene founded MGS MicroPure (as Technical & Sales Director) to compete with the giants of preservation, establishing the Paratexin brand name in the UK and several other markets (EU/ global). MGS MicroPure ceased trading in 2005. Since 2005, Dene has been employed by a major UK distributor of personal care ingredients, with his focus primarily on preservation systems. Dene’s articles are based solely on his personal opinions, observations and research, and are not intended to represent any official position of the part of his employer. Dene obtained a BSc (Hons) in Chemistry from the Open University in 1996. He also obtained the Professional Certificate in Management from the Open University in 1997. He has been an active member of the UK Society of Cosmetic Scientists since 1992, and has served 4 terms on the SCS Council, and is involved with the SCS Social Committee from 1993 to date; from 2004 – 7 as Social Secretary. Dene has presented papers at many SCS meetings and was President of the SCS (2009/10)
