What Is Intreleven Aldehyde Spec.?
Intreleven Aldehyde Spec. is a modern aroma chemical that belongs to the aldehyde family. It is made by Symrise, one of the world’s largest fragrance ingredient suppliers, though smaller firms may offer similar molecules under different names. The material is created through a controlled chemical process that starts with plant-derived building blocks. Because most of those building blocks come from upcycled streams, nearly all of the final product can be classed as renewable.
At room temperature the ingredient is a clear, watery liquid that shows no color. It stays that way over time thanks to an added stabilizer that keeps the molecule from breaking down. When stored in a cool dry space and kept in a tight container away from direct light, the shelf life is typically around two years before any noticeable loss in quality.
Perfumers reach for Intreleven Aldehyde Spec. whenever they need an instant burst of airy freshness. You will see it in fine fragrance, household products and just about every corner of fabric care. Because it delivers such strong effect at low dosage, the cost per formula stays reasonable, making it neither a bargain material nor a luxury one but comfortably in the middle.
The ingredient is offered at a purity of at least 95 percent, which gives perfumers a consistent result every time they use it. It is also readily biodegradable, so brands focused on sustainability appreciate its profile. All these points explain why its use has spread quickly since its launch and why it is now considered a staple in modern clean smelling accords.
Intreleven Aldehyde Spec.’s Scent Description
This molecule sits in the fresh family of perfumery. Off a blotter it opens with a bright aldehydic pop that feels like crisp linen fresh from the dryer. Within seconds a light floral breeze follows, suggesting jasmine petals and soft white blossoms. There is also a gentle ozonic touch that brings to mind cool morning air just after rain. A faint citrus sparkle and a hint of powder keep the whole effect smooth rather than harsh.
Perfumers break a fragrance into top, middle and base notes. Top notes greet you first, stay for a short while then give way to the heart. Intreleven Aldehyde Spec. lives almost entirely in that top space. It lifts other ingredients, makes them feel more open and helps the entire perfume announce itself from the first spray.
Projection is strong in the opening, so even a small amount can fill personal space quickly. Because the molecule is light it does not linger all day, yet it hangs on longer than many classic aldehydes. Expect two to three hours of noticeable presence on skin before it softens and slips into the background.
How & Where To Use Intreleven Aldehyde Spec.
Perfumers turn to this molecule when they need a quick burst of airy freshness at the very start of a scent. It slides neatly into clean white floral accords, watery ozone themes or anywhere a crisp linen twist feels right. Because it is quiet in the dry-down, it layers well over richer hearts without muddying them.
Typical use sits between 0.1% and 2% of the total formula. At 0.1% you get a gentle lift that makes citrus and light florals sparkle. Push it to 0.5% and the fabric softener vibe becomes obvious. Around 1% the aldehydic buzz is clear and the top feels room filling. Anything past 2% can start to smell waxy or fatty so keep trials small when exploring higher loads.
Intreleven Aldehyde Spec. excels in fine fragrance, soaps, shampoos and most fabric care bases. It stays bright even in high pH detergents which often dull other delicate notes. In candles it holds its fresh edge through the burn but needs help from fixatives to avoid flash off. The only places it struggles are heavy gourmand or deep oriental styles where its light voice gets lost.
The ingredient is easy to handle but pre-dilution makes weighing more accurate. Most labs keep a 10% solution in ethanol or DPG ready. This also lets you blotter test the material without overpowering the room. Blend it early in the build rather than tacking it on at the end so you can balance its opening power against the rest of the top notes.
Watch out for overdosing. Too much can push a perfume into harsh territory and mask subtle heart notes. Because it projects fast, even a trace above the sweet spot can change the first impression. Run multiple trials in small steps and always test on skin and in the final product base before locking the level.
Safely Information
Working with Intreleven Aldehyde Spec. calls for the same care you would give any concentrated aroma material.
- Dilute before evaluation: prepare a 1% solution in alcohol or dipropylene glycol so the raw vapors do not overwhelm the nose
- Avoid direct inhalation: never sniff straight from the bottle as the high concentration can irritate airways
- Ventilation: weigh and mix in a well ventilated space or under a fume hood to keep airborne levels low
- Personal protective gear: use nitrile gloves and safety glasses to prevent skin or eye contact
- Health considerations: some people may develop skin irritation or an allergic response, brief low level exposure is usually fine but long or repeated contact at high levels can be harmful, consult a doctor if pregnant or breastfeeding before handling
Always review the latest safety data sheet from your supplier and keep an eye on updates. Follow any IFRA guidelines for maximum usage in finished products to ensure your formula meets current standards and remains safe for consumers.
How To Store & Dispose of Intreleven Aldehyde Spec.
Keep the ingredient in a cool dry cupboard out of direct sunlight and away from heat sources. Refrigeration is not required but it does slow down oxidation and can stretch the shelf life beyond two years if the bottle is sealed well. Bring chilled stock back to room temperature before opening to avoid moisture condensing inside the neck.
Use amber glass or high quality fluorinated plastic bottles fitted with polycone caps. These caps create a tight seal that limits evaporation and keeps oxygen out. Avoid dropper tops since they let air creep in and often leak during transport. When a bottle is half empty decant the remainder into a smaller container so the headspace stays minimal.
Label every container clearly with the material name lot number date opened and the GHS warning symbols found on the safety data sheet. This stops mix-ups in the lab and reminds everyone of the basic handling rules at a glance.
For disposal first check local regulations. The molecule is readily biodegradable so small test quantities can usually be washed down the drain after dilution in plenty of water and detergent. Never pour concentrated residue into sinks or outdoor drains. Larger volumes or contaminated solutions should be collected in a sealed drum and passed to a licensed chemical waste contractor. Rinse empty containers three times let them dry then recycle or discard according to municipal guidelines.
Summary
Intreleven Aldehyde Spec. is a modern fresh aldehyde from Symrise that delivers a bright clean linen note with floral and ozonic hints. It excels as a top note booster in white floral fabric care and everyday clean themes while staying affordable and easy to dose at 0.1 – 2 percent.
Its strong opening power quick biodegradability and 90 percent renewable origin have made it popular among both niche perfumers and large formulators who want lift without a heavy footprint. Stability is solid yet the molecule can oxidize if left in half full bottles or in warm light-exposed areas so good storage habits matter.
You can buy commercial volumes direct from Symrise or through distribution partners. Smaller hobby sized packs often appear at fragrance supply shops and online resellers sometimes under generic names. Whether you are scaling a detergent line or spiking a personal project the material offers an easy route to instant airy freshness provided you respect its potency and keep the bottle tightly closed.
