Georgia Patent of the Month – November 2022
Air fresheners and fragrance diffusers are a great way to build aroma-driven experiences. If you’ve ever walked into a home that smells like fresh-baked cookies, or you can recall the way your parent’s home smells when you go and visit them, you know how powerful scent can be in creating memories and moods.
Using air fresheners and diffusers to set these aromatic moods relies on the formulation of the scent itself. Enviroscent, Inc. are experts in developing these products, replicating long-lasting scent products.
Most other fragrance-releasing devices use passive diffusion and are limited by a finite supply of the fragrance and its evaporation rate. Enviroscent uses a different, proprietary approach. Their newly patented solution uses pulp-based materials with a modulated scent release.
This pulp base material is formulated with numerous pores which provide a space to hold the volatile fragrance. The density of the pulp controls how quickly gas can diffuse through it. Enviroscent’s manufacturing process carefully controls this density and pore size, enhancing the diffusion rate to prolong the release of fragrance. The peaks and pores of the exterior also contribute to release rate. When the fragrance is emitted through a peak, it releases in all directions. Releasing from a flatter surface creates a more directional release. Carefully controlling where base notes and top notes are placed – and therefore where they will emit – can help to ensure the released fragrance matches the desired smell. For instance, sending the main scent out through peaks will let it fill the room, while the more directional release of the secondary scent ensures it remains a background scent.
Enviroscent’s careful production process supports their organic and healthy air freshener portfolio. The use of pulp base materials supports the release of wholly natural fragrance oils. The pulp itself is sustainable sourced and made of biodegradable and recyclable papers, starches, and silicas. From material to production process, the company strives to leave as little impact on the environment as possible, while leaving a big impact on their customers.
