What Is Neobutenone Alpha?
Neobutenone Alpha is an aroma molecule created to add bright green accents to perfume and fragranced products. It is offered by DSM-Firmenich, one of the largest suppliers of raw materials for scent, yet you may also find the same chemical sold under generic names by other distributors.
The material is obtained through a targeted chemical synthesis that builds the molecule from smaller building blocks. This approach lets the producer keep quality steady from batch to batch while following modern green-chemistry guidelines that cut down on waste.
At room temperature Neobutenone Alpha is a clear mobile liquid that pours easily and blends without fuss into most oils, alcohol or surfactant bases. Perfumers value its versatility so it shows up in fine fragrance, shampoo, soap and even scented candles. In creative labs it often serves as a reference point for the classic galbanum style of freshness.
On a smelling strip the note lingers around three days, a sign of good staying power for a green-toned ingredient. Unopened drums kept in a cool dark place typically stay in spec for about two years, though many users report it holding its full character well past that.
Cost wise it sits in the middle of the price range: not as cheap as simple citrus oils yet far from the most luxurious specialties. This balance between impact and cost explains why it is considered a workhorse in modern green accords.
Neobutenone Alpha’s Scent Description
Perfumers file Neobutenone Alpha under the green family, the group known for evoking cut leaves, stems and fresh sap. Off a blotter it opens with an intense flash of crushed galbanum resin fused with the impression of wild pine needles. Almost at once a juicy pineapple nuance bubbles up, adding a playful fruity twist that keeps the greenery from feeling too sharp. As minutes pass a soft rose-petal glow surfaces, giving the profile a gentle floral halo.
In the traditional top-middle-base framework this molecule starts as a powerful top note yet carries through into the heart before quietly fading. It does not stick around in the drydown like woods or musks, but its presence can still be sensed hours later as a delicate green whisper.
Projection is high during the first hour, throwing a clear aura that cuts through dense compositions. Longevity on skin averages four to six hours, longer in lotions or fabric care where the scent can cling well past a wash cycle.
How & Where To Use Neobutenone Alpha
Perfumers reach for Neobutenone Alpha when they need an unmistakable green flash that stays lively through the heart of a formula. It excels at lifting heavy florals, modern fougères and any composition that could benefit from a brisk garden-fresh accent. In citrus top notes it reinforces the cut-leaf effect while a touch in woody bases keeps the drydown feeling crisp rather than dusty.
The molecule can also anchor fruity accords. At around 0.5-1 % of the concentrate it pushes pineapple or mango themes forward without resorting to lactones. Below 0.1 % it behaves almost like a rose ketone and polishes petals in rose, peony or muguet blends. Trace amounts soften harsh aldehydes and add realism to melon or cucumber notes.
Thanks to a high flashpoint and good stability it works across fine fragrance, shampoos, soaps, detergents and candles. Saponification does not dull its impact so cold-process soap makers prize it. The only caveat is in gourmand or heavy amber styles where its sharp greenery may feel out of place unless balanced by sweet resins or musks.
Over-dosing can be a pitfall. Above 2 % of the finished fragrance it can turn metallic and swamp delicate accords. Some fabric softener bases show a faint solvent note if the level exceeds 0.3 % so running a small pilot batch is wise.
Preparation is straightforward: predilute to 10-20 % in ethanol, dipropylene glycol or triethyl citrate for easier weighing and smoother blending. Let the mix rest overnight because the material can bloom, slightly altering its perceived strength. Store the working solution in amber glass away from light to keep the pineapple facet intact.
Safety Information
Always dilute Neobutenone Alpha before evaluating it. Avoid direct sniffing from the bottle and work in a well-ventilated area to reduce vapor build-up. Wear nitrile gloves and safety glasses so accidental splashes do not reach skin or eyes.
Like many aroma chemicals it can provoke irritation or sensitisation in susceptible individuals. If you notice redness or discomfort wash the area with mild soap and water and discontinue use. Consult a medical professional before handling if you are pregnant or breastfeeding.
Short encounters with low concentrations are generally considered safe but prolonged contact with higher levels can lead to headaches respiratory irritation or skin issues. Keep the raw material out of reach of children and pets and clean spills promptly with absorbent paper followed by soap solution.
Dispose of surplus or expired material through a licensed chemical waste service rather than pouring it down the drain. Rinse empty containers, let them dry and recycle where local regulations permit.
Always refer to the latest Safety Data Sheet from your supplier for detailed toxicology flashpoint and first-aid advice. Check the document periodically for updates and formulate within the most recent IFRA guidelines to ensure consumer safety.
How To Store & Dispose of Neobutenone Alpha
Keep Neobutenone Alpha in tightly closed bottles placed in a cool dark cupboard away from heaters or direct sun. Refrigeration is optional yet helpful when you plan to keep a stock for more than a year because lower temperature slows oxidation.
Use containers fitted with polycone caps for both neat material and dilutions. These liners form a snug seal that limits evaporation. Avoid glass dropper bottles since their rubber bulbs allow air to creep in and may leach odor over time.
Try to store the liquid in vessels that are almost full. The smaller the air gap the less oxygen has a chance to react with the pineapple facet which is the part most prone to fading. If you must split a large drum into working bottles top them up with inert gas or simply use smaller bottles to keep headspace minimal.
Label every container clearly with the chemical name batch number date opened and hazard pictograms. This keeps your workspace orderly and lets anyone identify the contents at a glance in case of an emergency.
Though the molecule is ultimately biodegradable it should never be poured straight into drains. Small leftovers can be mixed with cat litter or sand, sealed in a bag then disposed of as household chemical waste according to local rules. Larger volumes need collection by a licensed disposal service. Rinse empty bottles with soapy water, let them dry then recycle the glass or plastic where facilities exist.
