Finally a thread that I feel somewhat qualified for answering.
I am hobby perfume collector and fragrance writer/blogger. If you are interested in reading some of my work, do check out my blog
(which hasn't been updated for ages) -
https://dandyness.wordpress.com or my last article for The Hindu Metroplus -

I had actually written about car fragrances for a column in the Hindu Metroplus last year, (link -
https://www.thehindu.com/life-and-st...le25308503.ece), but to add onto my limited knowledge about car fragrances and what I've mentioned in the column:
1. Fragrances work on the principle of
diffusion. Perfume collectors/fragrance enthusiasts usually judge a perfume on the parameters of
sillage (the 'scent-cloud' it leaves behind) and
longevity (how long does the sillage linger in the air).
2. Sillage and longevity depend on aromatic concentration, molecular composition of the
solvent and aromatics, ambient conditions and also to a large extent on who is smelling it. Believe it or not, but one of the most well-received theories on how we smell (by Luca Turin, a mad-genius of the science and perfume world) is that we have unique scent detection mechanism between our noses and brain which works on a principle similar to a mass spectrometer.
4. Adding to this, scent is one of our most primal senses and very closely linked to how we form our memories. Scent - through our first and last breath, is the first sense we experience with birth and is the last one to leave our consciousness when we die.
Every breath we have taken in the past affects our perception of smell in the present moment, over and above the biological differences in scent perception. Therefore factors like whether you smoke or not, where you grew up and events in your which life transpired around specific smells will affect your scent perception.
5. Therefore, going through all the posts on this thread, it is no surprise that different people like different smells. It is also true that people like widely
different scents based on their mood, environment, physiological factors. You might like the scent of wet earth while driving around on a hot May afternoon, and citrusy smells on a damp September evening or perhaps a warming sweet vanilla on a chilly January morning. Who you are with and what are you feeling also greatly affects how you smell.
6.
You must remember that you are always smelling; because you are always breathing. It's just that your brain chooses to actively ignores alerting you (like it ignores the sight of your nose in field of vision) of a smell unless essential, such as danger or arousal.
7. However, in automotive olfactory research, it was found that citrus smells tend to increase driver attention. Your personal perception might vary and therefore,
I tend to keep my own car scents as modular as possible.
8. This has been a long post and without getting into the details of different car fragrance options
(which you can in read my Hindu Metroplus article linked above), I shall offer my two pennies of what's commonly available in the Indian market:
- Passive diffusers:
a) Container based perfumes (in gel, liquid, solid form) - Generally you store them in the cup holder of your vehicle or stick them on your dash and they passively diffuse inside the car. Major downsides are they can become a projectiles in case of an accident or sudden braking, and cause injury to occupants. You will have to manually stow away the container or close its cap if you want to take a break from the smell. If left open, they will diffuse 24x7 and get over quickly. I do like My Shaldan's citrus scents.
b)Clip on diffusers - Similar to the can-type diffusers but more discreet, gentler (lower sillage) and minimal.They can either clip on to the air-con vents or to receipt holders in the sun-visor, depending on how long and strong you want them to smell. I am partial to Bath & Body Works clip-ons because of the fantastic range of scents, good build quality and great in-store experience.
c)Perfumed card/cardboards - similar to the above but even lower silage. Downside is the blindspot created if you hang them from IVRM. Little Trees is a classic but there are many 'Made in India' brands too. I had actually considered starting my own brand, with cards shaped in the form of religious figures/symbols which India in general puts on cars for auspicious reasons, but the plan never transpired
d)Homemade solutions like camphor, jasmine, essential oils, sandalwood, coffee beans, tea bags, potpourri etc. Major advantage to these are that they are easily available and cost next to nothing.
e)Activated charcoal has some credibility for absorbing odorous molecules in an environment.
- Powered diffusers - These are either battery powered or receive power through the 12 V socket or USB ports. They have the advantage of actively modulating diffusion to the strength and frequency of your preference. Downsides are that they eat up valuable space and power supply.
- In-built car perfume diffusers, often paired with air purifiers - They have the dual advantage of removing malodours as-well as infusing desirable smells. If you have a car with this feature then I'm guessing, you're best off trying out different perfume options that are compatible with your system.
- Car perfume sprays - This is my current go-to. I use a custom scent created by an independent perfumer but it is easy enough to use a cheap sample vial or an inexpensive perfume too. If you want your car to smell like your favourite perfume, try looking for a clone (cheaper rip-off but very similar olfactory signature) or use a travel atomizer and decant some of the real juice for car-usage. You may also consider diluting it with some denatured alcohol. I'm partial to Blue de Chanel in my car.
Phew! That was a bit too much gyaan
Cheers and many fragrant breaths to all!
