What Is Syvertal?
Syvertal is a specialty aroma chemical created by IFF, one of the world’s largest fragrance houses. While IFF holds the trademarked name, other suppliers often offer the same molecule under generic labels so it is readily available to independent perfumers and larger brands alike.
The material is made through controlled chemical synthesis, typically starting from simple petrochemical or plant derived building blocks that are combined, refined and purified until a clear, colorless liquid is obtained. Each batch is tested for purity so the scent profile remains consistent.
To the eye Syvertal looks like water: no color, no haze and a light fluid character that pours easily from the bottle. It is not prone to crystallizing at room temperature so it stays workable in the lab year round.
Usage is fairly common in modern perfumery whenever a natural green nuance is needed without relying on fragile plant extracts. Niche and mainstream brands both reach for it, as do formulators of soaps and fabric conditioners.
Properly stored the ingredient keeps its quality for about two to three years before the smell can start to dull. It sits in the mid range of the price spectrum, making it affordable for everyday creative work yet still refined enough for fine fragrance.
Syvertal’s Scent Description
Perfumers group Syvertal within the green family, a category known for notes that recall freshly cut stems and leaves.
On a blotter the first impression is intensely leafy and wet, almost like snapping a radish straight from damp soil. Within seconds a cool earthy facet appears that hints at freshly turned garden dirt mixed with dewy chrysanthemum petals. A faint fruity sparkle rounds the edges so the overall profile feels lively rather than harsh.
The note settles into what professionals call the heart or middle phase. That means it bridges the bright top notes that fade quickly and the heavier base notes that linger for hours. In a finished perfume formula Syvertal usually starts to show clearly after the opening evaporates and remains noticeable for several hours before retreating into the background.
Projection sits at a moderate level: strong enough to radiate a natural green aura yet not so forceful that it dominates every other material. Longevity is good, typically holding its character on skin or fabric well past the four hour mark, especially when paired with woody or musky bases that can anchor it further.
How & Where To Use Syvertal
Perfumers reach for Syvertal when they need a vivid splash of garden-fresh greenery that still feels polished. It slips neatly into stemmy accords with galbanum, violet leaf or blackcurrant bud, giving a juicy wet nuance that those classics sometimes lack. In floral hearts it sharpens jasmine, gardenia or chrysanthemum notes so they read brisk rather than cloying.
Its profile is most helpful in modern gender-neutral fragrances where a crisp green thread ties citrus openings to clean musks in the finish. When soap or shower gel formulas call for a natural leafy lift Syvertal steps in, although its staying power drops in high-pH bases so it may need a booster like cis-3-Hexenyl acetate.
Typical usage sits anywhere from a trace to about 3 percent of the total oil. At 0.1 percent it offers a quiet dew-kissed sheen. Pushed closer to 2 percent the radish bite becomes prominent and can overshadow delicate florals. Anything above 3 percent risks turning the whole scent into a sharp vegetable cocktail that many wearers find harsh.
Its fruity accent grows sweeter as concentration climbs, which can surprise the nose during compounding. Always dose in small steps, smell the blend on a fresh blotter and give it fifteen minutes before deciding whether more is needed.
In fine fragrance Syvertal shows good longevity and blends smoothly with alcohol. In powder detergent or fabric softener the molecule struggles, fading during the high-heat drying cycle. It performs best in liquid soaps, candles and reed diffusers where moderate warmth helps it bloom.
Prepare a 10 percent solution in perfumers alcohol or dipropylene glycol before measuring. The diluted form mixes faster and lets you correct a formula without hunting for single-drop accuracy. Store the stock solution in amber glass with a tight cap to keep the lively top intact.
Safely Using Syvertal
Work with any aroma chemical as you would with paint thinner or strong cleaning fluid. Dilute first, then smell the blotter at arm’s length. Never hover over an open bottle since even short whiffs of full-strength vapor can irritate the nose.
Good airflow is essential. A small fume hood or a desk fan pulling air away from you keeps vapors from building up. Nitrile gloves stop the liquid from soaking into skin and safety glasses protect against splashes.
Syvertal is not classed as a major sensitizer yet prolonged skin contact can cause redness in sensitive users. Anyone pregnant or breastfeeding should ask a doctor before handling fragrance materials. Short contact with low levels is generally considered safe but high doses or long sessions in a closed room may provoke headaches or nausea.
Spills wipe up easily with paper towel followed by soap and water. Avoid pouring waste down household drains; collect unwanted solution in a sealed container and send it to a chemical disposal site.
Always review the most recent Safety Data Sheet from your supplier before starting a project and check back for updates. Follow current IFRA guidelines to confirm you are inside the recommended limits for each product type.
How To Store & Dispose of Syvertal
Syvertal remains happiest in a cool dry cupboard away from direct sunlight and hot pipes. If you have room in a fragrance refrigerator the lower temperature slows oxidation even further but it is not mandatory for good shelf life.
Use bottles that can be filled as close to the top as practical so less oxygen sits above the liquid. Amber or cobalt glass blocks light while a polycone cap forms a tight seal that ordinary droppers cannot match. Keep your working dilution in its own container and open the main stock as rarely as possible.
Label every bottle with the material name the CAS number 4359-47-1 the dilution strength and the date it was poured. Add any hazard pictograms required by your local rules so anyone picking up the bottle sees the key warnings at a glance.
Store Syvertal well apart from acids strong bases or oxidizers that might trigger unwanted reactions. If a spill occurs mop it up with paper towels place them in a sealed bag then rinse the area with soapy water.
When a batch no longer smells fresh do not pour it down household drains. The molecule is classed as non biodegradable so it could linger in wastewater. Instead collect the liquid in a closed metal or HDPE container and take it to a licensed chemical disposal center. Small hobby quantities can sometimes be solidified with cat litter before disposal in accordance with local regulations but verify that option with your waste authority first.
Summary
Syvertal is a green category aroma chemical from IFF known for its vivid wet leafy scent that hints at radish chrysanthemum and gardenia. It bridges sparkling top notes and floral hearts giving perfumes a dewy garden snap without feeling raw.
The molecule offers moderate cost good performance in alcohol based fine fragrance and fair stability in soap though it fades in high heat laundry products. Because its character is bold and specific careful dosing is key to avoid turning a blend into a vegetable salad.
Popularity among perfumers stems from the way it freshens modern gender neutral creations and sharpens white florals while requiring only tiny amounts. Keep an eye on air exposure to preserve its brightness and remember that it is non biodegradable when planning disposal.
Commercial houses can order Syvertal directly from IFF or authorized distributors. Hobbyists will find smaller volumes through specialty perfume supply shops and generic aroma chemical vendors that list it under its chemical name or CAS number.
