What Is Prunella?
Prunella is an aroma material created by chemists in 1965 during a search for brighter fruit notes that could stand up in soap and detergent bases. Unlike essential oils that come from plants this material is produced in the lab through a controlled reaction of small organic building blocks. The result is a stable liquid that stays clear to slightly yellow at normal room temperature.
Because it is fully synthetic supplies are steady year-round and quality does not shift from batch to batch. This dependability has made Prunella a staple in many fragrance houses. You will find it on the ingredient lists of fine perfumes as well as everyday items like shampoos shower gels and candles.
In the world of raw materials Prunella sits in the mid-range for cost so perfumers can use it quite freely without pushing a formula over budget. It is stocked by most major distributors and is easy to source in both small and bulk volumes.
What Does Prunella Smell Like?
Perfumers place Prunella in the fruity family. Off a blotter it opens with a juicy plum impression that quickly shows hints of peach skin and dried coconut flakes. There is no sharp citrus edge here instead the note feels rounded and velvety almost like the flesh of a ripe stone fruit warmed by the sun.
On the fragrance pyramid Prunella starts in the heart and drifts into the early dry-down. It is not a fleeting top note but it does not anchor a composition the way woods or musks do either. Think of it as the bridge that carries a bright opening into a smoother base.
Projection is moderate so it lends a clear fruit accent without shouting over other ingredients. Longevity is impressive for a fruity note: on a standard smelling strip it remains distinct for about a week which gives formulas lasting mouth-watering charm on skin fabrics and air.
How & Where To Use Prunella
Prunella is a fun material to have on the blotter: it behaves well, blends quickly, and shows its plum side almost instantly, so you know right away if it is the right fit for your idea. It is not fussy about solvents and plays nicely with both alcohol and oil bases, making it a relaxed partner in the lab.
Perfumers reach for Prunella when they want a plush fruit tone that sits between peach and ripe plum without turning into sticky jam. A few drops can boost the heart of a white-floral bouquet, soften a berry accord, or round out the coconut facet in a beachy fantasy. Because it carries a subtle dried-fruit nuance, it also helps gourmand formulas feel fuller without adding obvious vanilla.
Typical usage sits anywhere from traces up to about 3 percent, although 5 percent is occasionally seen in soap where higher dosage is needed to push through the base. At 0.1 percent it merely polishes a composition, giving a gentle velvet glow. Above 1 percent the plum note becomes unmistakable and can even dominate lighter ingredients, so balance with woods, lactones, or a touch of musk if you want to keep the plum in check.
Applications are broad: fine fragrance, shampoos, shower gels, detergents, softeners, candles, and melts all tolerate Prunella well thanks to its good stability and respectable flashpoint. The only place it struggles is very high-heat air fresheners where temperatures exceed 100 °C for long periods, as some lift can be lost.
Prep work is simple. Most perfumers pre-dilute it to 10 percent in ethanol or DPG so dosing is easier and blotters dry faster. No special antioxidants or UV screens are required, and the material remains clear for months if the cap is kept tight.
Safely Information
Working with Prunella is straightforward yet the usual aroma-chemical precautions still apply.
- Always dilute before evaluation: reduce to around 10 percent in a carrier before smelling to avoid nasal fatigue or accidental overexposure.
- Never smell directly from the bottle: waft the scent from a blotter or strip to judge its character safely.
- Ensure good ventilation: blend in a fume hood or well-aired space to prevent inhaling concentrated vapors.
- Wear gloves and safety glasses: protect skin and eyes from splashes or spills during weighing and pouring.
- Health considerations: some people may experience skin irritation or sensitization, so handle with care. Consult a medical professional if pregnant or breastfeeding. Brief exposure to low levels is generally safe but prolonged or high-level contact can be harmful.
Always review the most recent Material Safety Data Sheet from your supplier before formulating and check it regularly for updates. Follow the current IFRA guidelines on maximum use levels to keep every blend within accepted safety limits.
Storage And Disposal
When Prunella is stored well it stays fresh for roughly two years after the production date. Many labs get three or even four years by keeping the bottle in a dedicated fragrance fridge set between 4 °C and 8 °C but this extra step is optional. A cool dark cupboard away from direct sunlight heaters and windowsills usually does the job.
Choose glass or coated aluminum bottles with tight polycone caps for both the neat material and any dilutions. Polycone inserts give a snug seal that limits evaporation and keeps oxygen out. Dropper tops look convenient yet they leak vapor and invite air inside so they shorten shelf life. Whenever possible decant into smaller bottles as you work through the stock so the headspace stays minimal and oxidation risk drops.
Label every container clearly with the name Prunella its strength if diluted the date it was filled and any hazard pictograms that apply. Sharpie ink fades on glass so use chemical-resistant labels or secure a printed tag under clear tape. Good labeling prevents mix-ups saves time during formulation and keeps co-workers safe.
If you ever need to discard Prunella treat it like other perfume concentrates. Small household amounts can usually be absorbed onto paper towels or kitty litter then sealed in a plastic bag and placed in the general trash but always confirm with local regulations first. For larger volumes contact a licensed hazardous waste service. The molecule is partly biodegradable yet concentrated dumps can still stress wastewater systems so avoid pouring it straight down the drain.
Summary
Prunella is a lab-made fruity note that gives fragrances a juicy plum accent with touches of peach skin and coconut. It is easy to blend fun to experiment with and finds a home in nearly any accord that needs a velvety fruit heart.
Stability is good enough for soap detergent and candles and the mid-range price lets perfumers dose it freely without wrecking the budget. Just remember that its character is specific so too much can push a formula into full-on plum territory. Store it cool keep the bottles topped up and you will have a reliable go-to material for years to come.
