What Is Ozofleur?
Ozofleur is a synthetic aroma chemical created by IFF to give fragrances a vibrant fresh lift. While IFF owns the trade name, a few specialty suppliers sell the same molecule under generic labels, so perfumers can source it from more than one place. It is made through a multi-step chemical process that starts with simple petrochemical feedstocks then gets purified to a very high grade suitable for fine fragrance.
At room temperature the material is a clear colorless liquid that looks much like water, yet a single drop packs a punch in scent compositions. The liquid flows easily, which makes it simple to weigh and blend in both oil and water-based products.
Ozofleur appears in many modern perfumes, household cleaners, soaps, shampoos, candles, and even fabric conditioners. Because it keeps its character in both high and low pH formulas, formulators reach for it whenever they need a clean fresh accent.
When stored tightly sealed in a cool dark spot it keeps its quality for roughly two to three years. The ingredient is vegan suitable though it is classed as non-biodegradable, a point manufacturers balance against its low use levels. In terms of cost it sits in the mid range: not a bargain synthetic yet not a luxury captive either, so it is accessible to both big brands and indie perfumers.
Ozofleur’s Scent Description
Perfumers slot Ozofleur into the fresh family, the same clan that includes airy marine notes and clean aldehydes. On a blotter it opens with a brisk ozone burst that feels like sea spray hitting hot pavement after a summer storm. There is a slight metallic twang, a wet stone nuance, and a tiny fizz that recalls sparkling mineral water. As the minutes pass a cool leafy facet peeks through, keeping the accord crisp rather than harsh.
Fragrance notes are often described as top, middle, and base. Top notes greet the nose first then fade, middle notes form the heart of the scent, and base notes linger until the drydown. Ozofleur is unusual because it shows up in all three layers. It explodes in the top, stays present in the heart adding airy space, and still hums quietly in the base six hours later, helping other notes feel cleaner and brighter.
The molecule projects well, so even small percentages push a composition outward and give it a breezy aura. Longevity sits in the moderate range: on skin the note remains noticeable for about six hours before it settles into a gentle whisper.
How & Where To Use Ozofleur
Perfumers pull Ozofleur into a formula when they want an instant breath of seaside air without leaning on traditional marine accords that can smell dated or heavy. It shines in the top and heart of a blend, pairing well with citrus, leafy green and light floral notes to boost brilliance. A trace can even lift woody or musky bases that feel flat, giving them a fresh sparkle that lasts for hours.
Typical dosage sits between 0.1 % and 3 % for fine fragrance, with the manufacturer allowing up to 6 % in most finished products. At very low levels it reads as a gentle watery shimmer. Push it past 2 % and the metallic side grows louder, adding an almost fizzy edge that can dominate softer materials. Beyond 4 % the note may turn harsh and soapy, swallowing subtle accords around it.
Ozofleur performs strongly in shampoos, deodorants and liquid detergents where its clarity carries through cleansing bases. It also holds up well in candles thanks to solid heat stability, though be prepared for a slightly softer ozone feel once the wax cools. Powder detergents and bleach show only moderate retention, so a higher load or a supporting booster like Calone or Aldehyde C-12 may be needed.
When replacing or reducing older marine synthetics, Ozofleur gives a modern twist without the heavy watermelon nuance some people dislike. It is also a smart alternative to certain aldehydes if you want sparkle but not the classic soapy vibe. That said, it will not supply the salty driftwood depth that materials like Ambergris type accords can offer, so layer wisely.
Before blending, many studios pre-dilute Ozofleur to 10 % in ethanol or dipropylene glycol. This makes fine-tuning easier and lessens the risk of over-dosing. The liquid is clear but slightly oily, so a quick warm-water bath helps it pour smoothly in cooler labs. As always label any dilutions with date, batch and strength to keep your library tidy.
Safely Using Ozofleur
Dilution is key. Always prepare a weaker solution before smelling or adding Ozofleur to a formula. Avoid direct sniffing from the bottle since the concentrated vapor can overwhelm your nose and irritate mucous membranes. Work in a well-ventilated space so fresh air can disperse any build-up. Gloves and safety glasses protect skin and eyes from accidental splashes.
Most people tolerate Ozofleur in normal perfume levels, yet any aroma chemical can cause skin irritation or an allergic response in sensitive users. If you are pregnant or breastfeeding consult a healthcare professional before handling fragrance ingredients. Short, low-level exposure is generally viewed as safe, but long sessions with high concentrations could lead to headaches or respiratory discomfort.
Clean spills right away with absorbent paper then wash the area with soap and water. Dispose of soaked materials in a sealed bag to reduce vapor release. Empty containers should be triple rinsed, dried and sent for chemical recycling where available.
Always review the latest Material Safety Data Sheet supplied by your vendor because recommendations can change as new research emerges. Follow current IFRA guidelines for total use level in each product type to make sure your creation meets global safety standards.
How To Store & Dispose of Ozofleur
Ozofleur behaves much like other specialty aroma chemicals: light, heat and oxygen are its biggest enemies. A refrigerator set between 4 °C and 8 °C slows oxidation and helps the note stay crisp for longer, yet a simple cool dark cupboard works for everyday use. Keep the bottle away from radiators, sunny windowsills and any source of ignition.
Choose containers that seal tight. Polycone caps grip the glass neck and create a reliable vapor barrier, while dropper tops often let air seep back in after every use. If you prepare a dilution, fill the bottle as high as practical to minimise the headspace that can speed up degradation. Gently purge the gap with nitrogen if you have it, although this is optional for hobbyists.
Label every container clearly with the name Ozofleur, its strength, date of dilution and basic hazard icons. Proper labelling avoids mix-ups and ensures anyone who handles your stock knows how to treat it safely.
When a batch has passed its best or you have leftover test blends, never pour them down the sink. Ozofleur is classed as non-biodegradable, so wastewater systems cannot break it down efficiently. Instead absorb small quantities onto cat litter or paper towels, seal them in a solvent-safe bag then send to a chemical waste facility. Larger volumes should go into a dedicated drum for flammable organics according to local regulations.
Rinse empty bottles three times with a solvent such as denatured alcohol before recycling the glass. Collect the rinse in your flammable waste container. Good housekeeping today prevents odour surprises and paperwork headaches later.
Summary
Ozofleur is an IFF fresh airy ingredient that delivers an ozone metallic splash with a leafy clean undertone. Perfumers use it to inject sparkle into top and heart notes, lift detergents and shampoos or modernise marine accords without the old-school melon profile.
The material carries solid stability across many product bases, projects boldly for around six hours and sits in the mid-price bracket for specialty synthetics. Its scent is distinctive so overdosing can edge into harsh territory, yet in balanced amounts it bridges bright citrus openings with wood or musk bases beautifully.
Commercial houses can source Ozofleur directly from IFF in drum quantities while indie creators often pick up smaller packs from reputable resellers or generic suppliers who stock the CAS-matched molecule. Whether you are scaling a global launch or tinkering with a weekend formula, careful dosing plus mindful storage will keep this modern ozone note working at its sparkling best.
