Diffuseur pour voiture SOJA&CO.,

car diffuser

a concentrated fragrance, crafted exclusively for small spaces.

an amber glass bottle made to hang from your rearview mirror. discreet, effective, always with you.

the most portable format in the collection

the wood does the work

how does it diffuse? same logic as our reed diffusers, on a smaller scale. the wooden cap absorbs the concentrate and slowly releases the fragrance throughout your car

the wood soaks it in

the wooden cap sits in the concentrate, drawing it up slowly. diffusion starts the moment you tip it

the car does the rest

the car's natural movements keep the wood in contact with the fragrance. nothing to do

tilt to refresh

when the intensity drops, tilt the bottle gently, without fully inverting it, to re-saturate the wood. the one gesture to remember

available fragrances

Frequently asked questions

longevity varies depending on conditions — heat, direct sunlight, and how often you tilt it all speed up diffusion. on average, a bottle lasts around 3 months, sometimes up to 15 weeks in milder conditions. when the concentrate runs out, simply refill with a 30 ml refill

the wooden cap does the work. it draws up the concentrate through capillary action, and the fragrance slowly evaporates from the surface. the car's natural movements keep the wood in contact with the scent, so there's nothing to do on a daily basis

gently tilt the bottle (without fully inverting it, to avoid spills) to rewet the wood. the gesture takes two seconds and works on the same principle as a reed diffuser you flip once a week. do it as needed, not on a fixed schedule

two options depending on the state of the bottle. when the concentrate runs out, refill with a 30 ml refill, sold separately. when the wooden cap eventually saturates after several refills, order a new bottle with a fresh cap

yes. cats in particular struggle to metabolize certain molecules naturally present in essential oils. our fragrances contain none of these compounds, and are free from phthalates and SVHC substances

essential oils oxidize quickly and shift in scent within weeks, especially in a sun-exposed car. they also naturally contain some of the most common allergens. a well-constructed fragrance by a perfumer is more stable, more consistent batch to batch, and allows for precise control over individual molecules
