Fragrances play a special role in our lives, adding a touch of magic to everyday experiences. From the calming scent of a reed diffuser in our office to the fresh aroma of clean laundry, fragrances are all around us. While creating the perfect fragrance involves combining various ingredients, choosing the right solvent—the liquid that blends and carries these ingredients—is just as important.


Why Solvents Matter


Think of a fragrance as a recipe with many ingredients. Each one has its own unique features, like how fast it evaporates or how it smells. A solvent acts like a glue, helping all these ingredients mix together properly and ensuring the fragrance works as intended, whether it’s in a candle, a cleaning product, or a personal care item.


The Right Match for the Job


Picking the right solvent isn’t always easy. It depends on what the fragrance will be used for. For example:

• 
  Dipropylene glycol (DPG) works great in personal care products but isn’t suitable for candles due to its low volatility, which also limits its use in reed diffusers
• Dipropylene glycol methyl ether (DPM) is often used as a fragrance carrier for liquid electrical plugins. However, its strong odor can impact the fragrance profile, and it is considered a VOC under CARB regulations, limiting its use in certain markets.
• 3-methoxy-3-methyl-1-butanol (MMB) has an appropriate evaporation rate but a mild smell that can interfere with the fragrance’s intended scent. This often requires higher concentrations, which can drive up costs.
• Ethanol, while cost-effective, evaporates quickly and has a strong smell that may disrupt the sensory experience. It is also flammable and toxic, prompting producers to seek safer alternatives.

Sustainability and Safer Solutions

Solvent selection today isn’t just about performance—it’s also about meeting safety and sustainability goals. Companies now focus on the full life cycle of their products, from sourcing raw materials and reducing carbon footprints to ensuring biodegradability and using eco-friendly packaging. This shift reflects growing consumer demands for greener, more ethical options.

A perfect example is Augeo® Clean Multi, a bio sourced   solvent with low odor and high solubilizing power, classified as environmentally friendly  . It can replace petrochemical-derived dipropylene glycol (DPG) on a 1:1 basis, offering a more sustainable alternative with a 40% lower carbon footprint. Additionally, its higher volatility improves fragrance diffusion, enhancing the blooming effect and creating a stronger perception of cleanliness.



Exciting Innovations

Augeo® Clean Multi is gaining attention for its versatility. With a mild smell, it is ideal for products like candles and reed diffusers, helping fragrances last longer. Innovations like these, along with the rise of biobased solvents, promise safer, eco-friendly solutions that align with modern values.
