What Is Aldehyde C11 Moa?
Aldehyde C11 Moa is an aroma chemical created to give fragrances a lively splash of fresh orange peel blended with a breezy clean nuance. The best-known producer is Symrise, a global supplier of perfumery ingredients, yet a few other flavor and fragrance houses also offer comparable versions under slightly different trade names.
Rather than being pressed from fruit, the molecule is made in a lab through controlled oxidation of a fatty alcohol followed by careful purification. This synthetic route keeps quality consistent and ensures the high purity needed for fine fragrance work.
At room temperature it appears as a perfectly clear liquid that looks much like water but carries a noticeably crisp scent. The material is easy to blend because it stays fluid and does not crystallize.
Perfumers reach for Aldehyde C11 Moa quite often. It shows up in sparkling citrus accords, marine themes and even fabric-care bases. Thanks to the built-in stabilizer the shelf life is comfortable; stored in a cool dark place the molecule typically stays in specification for two to three years.
The cost sits in the mid range for aldehydic materials. It is not as pricey as some niche naturals yet commands a little more than standard commoditized aroma chemicals, reflecting its high purity and versatility.
Aldehyde C11 Moa’s Scent Description
This ingredient is generally filed under the citrus family because its first impression evokes the zest of a freshly peeled orange. On a scent strip it bursts open with a bright aldehydic sparkle that feels fizzy and airy, quickly joined by sweet orange rind. Within seconds a salty marine breeze peeks through, adding coolness and keeping the character from turning too sugary. A faint waxy note trails behind, reminiscent of clean sun-dried linen.
In the traditional fragrance pyramid aldehydes like this live in the top portion. They are among the first notes to greet the wearer, lifting heavier elements that follow. Aldehyde C11 Moa excels at that task, giving immediate lift while linking seamlessly into citrus hearts.
Projection is confident during the opening minutes, easily radiating from a scent strip or freshly sprayed skin. After about half an hour the diffusion settles but a gentle cleanliness lingers. On paper the aroma remains detectable for a full day, although the punchy citrus edge fades sooner leaving a subtle soapy freshness behind.
How & Where To Use Aldehyde C11 Moa
Perfumers pull Aldehyde C11 Moa off the shelf when they want to kick off a composition with quick sparkling lift yet keep the vibe natural and juicy. It is a go to choice for orange top accords because it marries aldehydic fizz with an authentic peel note, filling the gap between pure citral and more abstract laundry aldehydes. When a brief marine breeze or a freshly washed textile nuance is also desired this molecule covers both without stacking several separate ingredients.
Typical inclusion levels run from mere traces up to about 2 percent of the concentrate. At 0.05 percent it simply freshens and brightens, acting nearly invisible while it pushes diffusion. Around 0.5 percent the orange peel flashes clearly and the linen effect moves forward. Above 1 percent the salty marine note gains weight and can shift the whole accord toward ozonic territory. Going past 2 percent risks a harsh waxy edge that can read as candle smoke or hot iron so moderation is key.
Formulators reach for it most often in sparkling citrus colognes, aquatic masculines, fruity florals, fabric care boosters and air fresheners aimed at a clean sea breeze impression. It also performs well in soaps where its tenacity survives the curing stage and keeps bars smelling crisp. The flash point of about 81 °C means it is stable enough for candles yet still volatizes nicely once the wax warms.
Aldehyde C11 Moa is less convincing in heavy oriental bases or gourmand blends where its sharpness can clash with dense vanilla or resin. If an orange accord already leans sweet, lighter aldehydes such as Decanal might be safer. Likewise, in delicate white florals a tiny dose is fine but overuse can mask petals with detergent facets.
Preparation is straightforward. The material is a clear mobile liquid that dissolves quickly in ethanol or dipropylene glycol. Weigh it accurately because tiny shifts in dosage make a big difference to the opening. Pre dilute to a 10 percent solution for trials to avoid aromatic shock when adding to a blend. No extra antioxidants are needed thanks to the built in stabilizer yet storing the working solution in amber glass away from heat keeps it at peak freshness.
If the formula will live in surfactant bases such as shampoo or dish soap a short bench stability test is wise. Check for odor drift after a week since aldehydes can hydrate in water rich systems. For candles combine with a small amount of antioxidant BHT if long term storage is planned, then test burn for any unexpected metallic notes.
Safely Information
Always handle Aldehyde C11 Moa with care. Dilute the raw material before evaluating its odor to avoid overwhelming the nose. Do not sniff directly from the bottle. Work in a well ventilated area so vapor does not accumulate and wear nitrile gloves plus safety glasses to keep skin and eyes protected.
Most users experience no issues at the low concentrations typical in fragrance but aldehydes can trigger irritation or sensitization in some individuals. Anyone who is pregnant or breastfeeding should seek medical advice before extensive exposure. Short encounters with diluted forms are generally safe while prolonged contact with high strength solutions can lead to headaches or dermatitis.
If skin contact occurs wash immediately with plenty of soap and water. Should eye exposure happen rinse with clean water for several minutes and seek medical help if discomfort persists. In case of accidental ingestion call a poison center and provide the full material name.
Remember that safety data can be updated as regulations evolve. Consult the latest Material Safety Data Sheet from your supplier each time you order a new batch and follow any new handling advice. Check current IFRA guidelines for maximum allowable levels in your intended product category and design your formula so the finished dilution stays comfortably below that threshold.
How To Store & Dispose of Aldehyde C11 Moa
Keep Aldehyde C11 Moa in a tightly sealed amber glass bottle placed in a cool, dark cupboard away from direct sunlight or radiators. A dedicated fragrance fridge set around 4 °C is even better because lower temperatures slow oxidation and extend shelf life.
Use polycone caps on both neat material and dilutions. Their flexible conical liner forms a snug seal that beats the loose fit of dropper tops and prevents the aldehyde aroma from escaping into the workspace. Avoid plastic droppers for long term storage, as they allow air to creep in and can leach solvent-sensitive plastics into the concentrate.
Whenever possible decant the liquid into the smallest practical bottle so the container stays nearly full. Less headspace means less oxygen contacting the surface which helps preserve that bright orange peel sparkle. If you have only a half-filled bottle, top it off with an inert gas spray before closing.
Label every container clearly with the full ingredient name, date received, batch number and hazard pictograms. Include personal protective equipment reminders so anyone grabbing the bottle later remembers to wear gloves and goggles.
For disposal, first check local regulations. Small hobby quantities can usually be mixed with cat litter or another absorbent, sealed in a bag then placed in household hazardous waste collection. Never tip raw aldehyde down the sink because its strong odor can linger in drains. Larger volumes from a studio or factory should go to a licensed chemical disposal service.
Aldehyde C11 Moa is inherently biodegradable, so trace residues in finished consumer products break down in normal wastewater treatment. Rinse bottles with a little alcohol, add the rinse to your waste solvent drum and let the clean glass dry before recycling.
Summary
Aldehyde C11 Moa is a clear liquid aroma chemical from Symrise that delivers an effervescent blend of orange peel aldehydic fizz and a hint of sea breeze. Perfumers use it as a top note booster, especially in citrus, marine and clean linen styles, at doses from mere traces to about 2 percent.
The material enjoys steady popularity because it offers high purity, good stability and versatile performance across fine fragrance, fabric care and even candles, yet its distinct character means it can clash with very sweet or heavy bases if overdosed.
Cost sits in the mid range and the built-in stabilizer makes storage straightforward, though refrigeration and full bottles help preserve freshness. Safety measures are simple: dilute before smelling, ventilate the workspace and protect skin and eyes.
Commercial buyers can source Aldehyde C11 Moa directly from Symrise or authorized distributors. Smaller bottles for hobbyists and indie brands are often available through specialty perfume suppliers and reputable resellers who stock either the Symrise grade or equivalent generics.
