What Is Oxane 50 Tec?
Oxane 50 Tec is a synthetic aroma molecule created by DSM-Firmenich to give fragrances a vivid blackcurrant signature. While DSM-Firmenich owns the original trade name, other aroma houses may offer comparable materials under generic labels that carry the same chemical identity.
The molecule is produced through conventional chemical synthesis, a step-by-step build-up of smaller building blocks into the finished compound. The manufacturer states that its research and development team applies green chemistry principles wherever the process allows, keeping waste and energy use in check.
At room temperature the material presents itself as a clear to very slightly yellow liquid that pours easily. It blends well with perfume oils or solvent bases, which makes it straightforward to handle in both artisan and industrial settings.
Perfumers reach for Oxane 50 Tec quite often, especially when they want a juicy fruit tone that feels natural yet powerful. It lasts around one day on a paper blotter, giving enough working time during formula evaluation. When kept in tightly closed containers away from heat and light, most suppliers recommend using it within 24 to 36 months for optimum performance.
Cost wise it sits in the mid range of specialty fruity aromatics: not the cheapest option on the shelf yet accessible enough for fine fragrance, body care and household applications alike.
Oxane 50 Tec’s Scent Description
Perfumers file Oxane 50 Tec under the fruity family. Smelled on a blotter it opens with an unmistakable burst of ripe blackcurrant juice touched by the tang of grapefruit zest. A subtle sulfuric spark gives the fruit a realistic edge, much like the sharp whiff released when you crush a handful of currant berries. Within seconds a tropical wave drifts in, mixing passion fruit pulp and a hint of mango skin. Underneath, a faint green note recalls the stems and leaves, tying the whole accord together.
In the traditional top-middle-base framework the molecule sits mainly in the top to early heart zone. It lights up a perfume within the first minutes, then anchors itself just long enough to bridge into florals or other fruits in the heart. On its own it is not a fixed base note, yet its presence can still be detected several hours later as a nuanced fruit shadow.
Projection is solid: even at low dosage the material radiates clearly for the first hour giving the composition a bright halo. Longevity on skin lands in the medium bracket, often six to eight hours depending on the formula, after which it fades to a gentle fruity whisper.
How & Where To Use Oxane 50 Tec
Perfumers turn to Oxane 50 Tec when they want an unmistakable blackcurrant flash that feels juicy and fresh rather than candied. It can act as a solo top note but more often anchors a fruit accord with Isospirene, Helional or citrus aldehydes, lending depth to grapefruit, passion fruit or mango effects. In a modern chypre it sharpens the berry nuance in a cassis top, while in a solar floral it pushes jasmine and ylang into a tropical space.
Typical inclusion ranges from a trace level up to about 5 percent of the concentrate. At 0.1 percent it simply brightens a formula, adding a crisp peel impression. Around 1 percent the sulfuric facet becomes obvious and the blackcurrant heart dominates, which suits niche fine fragrance or shampoo bases that need extra lift. Above 3 percent the material can overpower lighter partners, throwing the balance off and introducing an unwelcome catty edge.
Because Oxane 50 Tec projects strongly, it pairs best with equally assertive notes or with dampening modifiers like musks and creamy lactones. It excels in citrus top accords where natural grapefruit oil is restricted by safety limits. Conversely it can feel out of place in powdery orientals or delicate tea accords unless kept at microdose levels.
The ingredient is robust in soaps, detergents and candles, surviving high pH and moderate heat without breaking down, though some of its sparkle softens in wax. In alcohol perfumes it dissolves instantly; for water based products premix it into a solubiliser or a small slug of ethanol first to avoid cloudiness.
Prep work is minimal: check the flashpoint if hot compounding, keep the bottle tightly closed and weigh with a 0.01 g scale because small errors translate to big olfactory swings. A quick bench dilution at 10 percent in ethanol is recommended for day-to-day dosing and smelling.
Safety Information
Always work with Oxane 50 Tec in a diluted form. Avoid waving the open bottle under your nose; instead smell from a blotter in a well ventilated space. Wear nitrile gloves and safety glasses so the liquid never touches skin or eyes.
Like many aroma chemicals it can trigger irritation or sensitisation in some people, especially at higher concentrations or after repeated contact. Anyone who is pregnant or breastfeeding should check with a healthcare professional before handling fragrance raw materials.
Short, low level exposure during normal compounding is generally considered safe but prolonged inhalation of concentrated vapours or skin contact with the neat liquid increases health risks. Wash hands after use and keep food and drinks away from the workbench.
Dispose of spills by absorbing them on an inert material such as vermiculite and follow local regulations for chemical waste. Store the bottle tightly sealed, upright and away from heat sources or direct sunlight.
Always consult the latest Material Safety Data Sheet supplied by your vendor for detailed toxicological and regulatory information and review it periodically because updates are common. Adhere to the current IFRA guidelines that set maximum usage levels for each product category.
How To Store & Dispose of Oxane 50 Tec
Keep Oxane 50 Tec in a tightly sealed amber glass or stainless-steel container placed in a cool dark cupboard away from direct sunlight and heat sources. Refrigeration is optional yet helpful for extending shelf life, just allow the bottle to reach room temperature before opening to avoid moisture condensation.
Use polycone caps for both neat material and dilutions because they form an airtight seal. Avoid dropper bottles since their loose fit invites slow evaporation and oxidation. Whenever possible store the liquid in a container that is almost full so less air sits above the surface.
Label every bottle clearly with the material’s name, concentration, batch number, flashpoint and hazard symbols. Add the preparation date so you can track ageing and plan periodic odor checks.
For short-term handling keep the working bottle inside a secondary plastic tub to catch drips. Wipe threads and caps after each use so residue does not crystalise or leak.
Small spills can be soaked into vermiculite or paper towels then sealed in a plastic bag for hazardous waste collection. Never pour the chemical or alcoholic dilutions down the drain. While the molecule shows low water solubility it is not readily biodegradable so uncontrolled disposal can burden wastewater systems. Larger quantities should be handed to licensed chemical disposal services that follow local environmental regulations.
Summary
Oxane 50 Tec is a synthetic fruity note from DSM-Firmenich prized for its vivid blackcurrant signature laced with grapefruit, passion fruit and a slight sulfuric bite. It lifts citrus accords, deepens tropical mixes and adds realism to jasmine or rose when used in moderation.
The ingredient enjoys steady popularity because it delivers big impact at low doses, survives pH stress in soaps and remains affordable compared with many exotic fruit naturals. Its medium volatility means good top-heart presence yet it should be protected from excess air or heat to avoid dulling.
Creative perfumers value its specificity so be mindful that over-use can dominate lighter compositions. Price sits in the mid tier making it accessible for fine fragrance, personal care and household products alike.
Commercial quantities come straight from DSM-Firmenich or authorised distributors. Hobbyists and small brands can source it in smaller packs from specialty resellers or under generic chemical names that match the same CAS profile, letting anyone explore its juicy blackcurrant charm without committing to industrial volumes.
