What Is Isoraldeine 70 P Dsm?
Isoraldeine 70 P Dsm is a lab made aroma molecule first introduced by DSM scientists in 1972. It was developed to give perfumers a reliable violet style effect that was hard to source from nature at the time.
The molecule is produced through a multi step synthesis that starts with simple petrochemical feedstocks. A precise series of reactions, including controlled oxidation and condensation, leads to the final substance. Because each batch is built from the ground up in stainless steel reactors, quality stays consistent from drum to drum.
At room temperature the ingredient appears as a clear, slightly viscous liquid. It pours easily, so handling in the fragrance lab is straightforward. The product is supplied at 70 percent strength on a carrier to make weighing and blending simpler.
Isoraldeine 70 P Dsm sits in the mid range of cost for specialty fragrance materials. It is not as pricey as rare naturals yet it is more of an investment than everyday aroma chemicals like limonene. The balance between price and performance has made it popular with perfumers across fine fragrance, home care and personal wash categories.
Thanks to its four day staying power on a smelling strip, formulators value it for projects that require noticeable scent life. You will find it in commercial perfumes, scented candles, shampoos and even fabric softeners.
What Does Isoraldeine 70 P Dsm Smell Like?
Perfumers classify this material in the floral family.
On a fresh blotter the very first impression is a cool violet petal effect that feels soft and airy rather than green. Within a minute a gentle powder nuance shows up, giving the profile a cosmetic vibe similar to classic face powder. As the minutes pass a subtle woody tone anchors the floral part and keeps it from smelling too sweet. If you pay close attention there is also a bright raspberry touch that lifts the overall character.
In the traditional top, middle and base structure Isoraldeine 70 P Dsm sits firmly in the heart. It starts to speak after the top notes have flashed off then carries through for many hours into the dry down, lending continuity between the opening sparkle and the deeper base materials.
Projection is moderate; it does not flood the room but has an elegant personal radius that feels polished. Longevity is impressive for a floral heart note, lasting most of the day on skin and well over twenty four hours on fabric or blotter.
How & Where To Use Isoraldeine 70 P Dsm
First off this is an easygoing material to handle. It pours smoothly, the odor is pleasant rather than sharp and it does not rush out of the bottle like some lighter aromatics so spills are unlikely.
Perfumers reach for Isoraldeine 70 P Dsm when they want a clean modern violet effect that lasts. It can be the main driver of a violet heart accord or a supporting note that softens woods, fruits or musks. In rose formulas a touch rounds off green edges, while in raspberry accords it adds realism without extra sweetness. When a brief hint of lipstick powder is needed in a cosmetics inspired fragrance this molecule delivers that vibe in one stroke.
Because the scent leans airy and transparent at low dose and more powdery at higher dose, concentration guides the creative outcome. Traces to 0.2 percent brighten top notes, 0.3 to 1 percent sit squarely in the heart for a classical floral character and anything above 2 percent pushes a full on violet cosmetic signature. Most finished perfumes fall between 0.5 and 3 percent though functional products like fabric softener may go up to 5 percent thanks to the four day tenacity.
Applications are broad: fine fragrance, haircare, body wash, home cleaning products and candles all benefit from its stability. The only notable limitation is high temperature soap cookers where extended exposure above its flashpoint can strip out some character, so late addition or premix in a carrier is advised.
Prep work is minimal. Many labs cut it to 10 percent in dipropylene glycol or TEC for easier weighing and more accurate micro dosing. Once diluted, store in an amber glass bottle to slow oxidation and keep that violet note crisp.
Safety Information
Working with any concentrated aroma chemical calls for basic precautions to keep your workspace safe and your senses sharp.
- Always dilute before evaluation: prepare a 10 percent or weaker solution so the odor can be judged accurately without overwhelming the nose
- No direct sniffing from the bottle: wave the bottle cap gently under your nose instead of inhaling the full strength vapors
- Ventilation: blend and smell in a well ventilated area or under a fume hood to disperse airborne molecules
- Personal protective equipment: wear nitrile gloves and safety glasses to avoid skin or eye contact with the neat material
- Health considerations: some aroma chemicals may trigger irritation or allergies, brief low level exposure is generally safe but prolonged or high level exposure can be harmful, consult a medical professional before use if pregnant or breastfeeding
Always review the latest safety data sheet supplied with your batch and keep an eye on updates as regulations evolve. Follow current IFRA guidelines for maximum usage levels to ensure your finished product is both enjoyable and safe.
Storage And Disposal
Unopened drums or bottles of Isoraldeine 70 P Dsm stay in good shape for roughly five years. Once a container is opened expect two to three years of reliable performance if you store it well.
Refrigeration is helpful but not essential. A cool dark cupboard away from direct sun and heat sources protects the liquid just fine. Aim for a steady temperature under 20 °C and keep the bottle tightly closed when not in use.
Switch the standard cap for a polycone cap on any dilution you prepare. Polycone liners create a snug seal that cuts down on slow air leaks. Dropper bottles look convenient but rarely seal well enough and let oxygen creep in, so skip them for long term storage.
Try to keep each bottle as full as practical. The smaller the air space the less chance oxygen has to start oxidation that dulls the violet note. If a stock bottle is half empty transfer the remainder to a smaller vessel to minimize headspace.
Label every container clearly with the ingredient name, strength of any dilution, date of preparation and basic hazard phrases. Good labeling prevents mix-ups and speeds up safety checks when you are working quickly.
When it is time to dispose of leftovers do not pour the neat material straight down the drain. First contact your local waste authority for rules on disposing of fragrance chemicals. Small residues can usually be diluted heavily in warm soapy water then flushed while the tap runs, but larger volumes should go to a licensed chemical waste or incineration facility. Isoraldeine 70 P Dsm is only partially biodegradable so controlled disposal keeps it out of waterways.
Summary
Isoraldeine 70 P Dsm is a synthetic violet aroma chemical that brings a soft powdery raspberry-tinged floral effect to a broad range of formulas. It behaves like a reliable heart note with four day tenacity on blotter so it bridges top sparkle and base depth with ease.
Perfumers lean on it for modern violet accords, to polish roses or to add a chic cosmetic vibe in lipstick style blends. It stays stable in most product bases from fine fragrance to fabric softener which explains its steady popularity in labs around the world.
The cost sits in the mid tier, its stability is solid and the scent is specific enough to stand out yet versatile enough to support woods, fruits and musks. In short it is a fun tool for both beginners and seasoned noses looking to add long lasting floral elegance to their creations.
