What Is Cedroxyde?
Cedroxyde is a liquid aroma chemical designed to give fragrances a dry woody accent. It was first introduced by DSM-Firmenich, one of the leading suppliers of fragrance materials. Over time other aroma houses have offered their own versions that match the original profile, so you may find it sold under alternative trade names as well.
The molecule is produced through chemical synthesis, meaning it is built step by step from smaller building blocks rather than extracted from wood itself. The production process follows modern green-chemistry guidelines that aim to cut waste and energy use wherever possible.
At room temperature Cedroxyde looks like a clear to pale yellow oil that pours easily. It mixes well with most perfume solvents and keeps a consistent smell even after repeated openings of the drum.
Formulators reach for Cedroxyde quite often because it gives an instant cedar-like backbone without the price or supply swings of natural wood oils. You will see it in fine fragrance, body wash, soap, fabric care and even scented candles. When stored in a cool dark place the material stays in good shape for roughly two to three years before the aroma starts to fade.
Budget wise it sits in the affordable bracket compared with many specialty woods, making it a practical choice for both prestige and mass-market work.
Cedroxyde’s Scent Description
Cedroxyde is grouped in the woody family. On a blotter the first impression is crisp freshly cut cedar. Within a minute or two you start to notice a slightly earthy tone that recalls patchouli leaves and a gentle amber warmth that rounds the edges. The overall effect is dry, smooth and quietly elegant rather than rough or smoky.
Perfumers talk about top, middle and base notes to describe how a scent unfolds over time. Top notes flash off quickly, middle notes set the mood, while base notes linger for hours. Cedroxyde sits firmly in the base. Once the brighter parts of a perfume drift away this material keeps working in the background, giving structure and a long lasting wood aura.
Projection is moderate to strong depending on the dose. It radiates clearly for the first few hours then settles into a soft haze that can still be smelled on skin or fabric the next day. In blends it helps anchor more volatile ingredients and stretches the overall wear time of the perfume.
How & Where To Use Cedroxyde
Perfumers reach for Cedroxyde when they need a dry yet refined wood note that lifts an accord without turning it smoky or resinous. It fits neatly into cedar, patchouli or modern amber bases and deepens fougère structures where lavender might feel too bright on its own. A small amount can also give body to citrus or floral blends by adding a discreet woody spine that keeps top notes from floating away too quickly.
Typical usage sits anywhere between a trace and 5 percent of the total concentrate. At 0.1 percent the material whispers cedar shavings and dryness, useful for fine tuning balance without declaring itself. Around 1 percent the ambery warmth becomes clearer and the note starts to shape the overall personality of the perfume. Push it closer to 5 percent and Cedroxyde turns into a principal voice, steering the scent toward a crisp pencil-wood effect that can crowd softer notes if not checked.
Over-use brings two main risks: the formula may feel flat and dusty instead of rich, and the drydown can become stubbornly linear. If you already have other strong woody synthetics like Iso E Super or Z-11 in place, dial Cedroxyde back to avoid overlap. In soaps or shampoos the material holds up well during processing but can mask delicate floral nuances, so a trial batch is wise.
Cedroxyde is oil-soluble and blends smoothly into most perfume bases with only gentle stirring. No special antioxidants are required, though adding a hint of BHT can prolong shelf life in high-surfactant products. Pre-diluting to 10 percent in ethanol or DPG makes weighing easier and reduces the chance of accidental overdose. Always label the dilution clearly and store it away from acidic materials that could shift its odor profile.
Because the molecule is stable up to candle temperatures it performs nicely in scented wax, lending a solid woody backbone that lasts through the burn. In spray cleaners or softeners, stick to the lower end of the range so the room does not feel overly dry or dusty. When in doubt, build the concentration stepwise and evaluate each version after a full 24-hour maceration.
Safely Using Cedroxyde
Good lab habits keep work with Cedroxyde worry-free. Always dilute the raw material before smelling it so you avoid the shock of a concentrated hit. Never sniff straight from the bottle as the vapor, though low, can overwhelm your nose and muddle judgment. Work in a space with steady airflow or use a small fume hood, and slip on nitrile gloves plus safety glasses to protect skin and eyes from accidental splashes.
Like many aroma chemicals, Cedroxyde can cause mild skin irritation or trigger allergies in sensitive users. If you notice redness or discomfort wash the area with soap and water and seek medical advice if symptoms persist. Pregnant or breastfeeding individuals should consult a healthcare professional before frequent handling since data on long-term exposure is limited. Short contacts at low concentrations are generally regarded as safe, yet repeated high-level exposure could pose respiratory or dermal risks.
Clean any spills right away using an absorbent cloth then wash the surface with warm soapy water. Keep containers tightly closed when not in use to limit oxidation and vapor buildup. Dispose of unwanted material by following local chemical waste rules—never pour it down the drain.
Before formulating, download the latest safety data sheet from your supplier and review it often because updates can occur without notice. Follow current IFRA guidelines to confirm your chosen percentage sits inside the recommended limits for each product type. Careful adherence to these documents helps ensure both creative freedom and consumer safety.
How To Store & Dispose of Cedroxyde
Cedroxyde keeps its punch longest when stored in a cool dark spot away from heaters or direct sun. A dedicated fragrance fridge is even better because steady low temperatures slow oxidation.
Use bottles with polycone caps for both the neat material and any dilutions. The liner makes a tight seal that stops slow leaks of scent and air. Dropper bottles often let air creep in so leave those for short term test blends.
Try to keep each bottle as full as possible. Top up small amounts into a smaller vial rather than leave a half empty one. Less headspace means less oxygen touching the liquid which helps the woody note stay crisp.
Label every container clearly with the name Cedroxyde, the dilution strength, and basic safety notes like “irritant” or the GHS symbols. Good labels prevent mix-ups and remind anyone handling the bottle to use gloves and eye protection.
If you spill some, wipe it with an absorbent cloth then wash the area with warm soapy water. Collect rags or paper towels in a sealable bag before tossing them in the chemical waste bin.
Unused stock should go to a licensed waste handler. The molecule is slow to break down in water and can build up in the environment, so do not pour leftovers down the drain or into soil. Small hobby amounts can be taken to a local hazardous drop-off center where solvents and paint thinners are accepted.
Summary
Cedroxyde is a lab made woody note from DSM-Firmenich that delivers a dry cedar-patchouli vibe with a soft amber glow. It acts as a long lasting base, giving depth to chypre, fougère and modern amber styles while staying affordable and easy to blend.
The material is stable in soap, candles and cleaners yet still shines in fine fragrance, making it popular with both big brands and indie makers. Its scent is specific and linear, so pair it with livelier woods or florals if you want extra movement.
Cost sits in the moderate range and shelf life reaches several years when stored cool and sealed tight. Remember to limit headspace, choose the right cap and follow IFRA limits for leave-on products.
You can buy Cedroxyde in bulk straight from DSM-Firmenich or through their distributors. Smaller hobby sizes often appear at perfume ingredient shops and re-bottlers who carry generic versions once patents expire. Always check the CAS number 71735-79-0 to be sure you are getting the real molecule.
