What Is Ethyl Caprylate?
Ethyl Caprylate is an aroma chemical belonging to the family of esters, the same broad group that gives many fruits their appetising smell. The material is produced on an industrial scale, with Symrise offering a high-purity grade, and other suppliers around the world making comparable versions for the fragrance market.
It starts life in the lab through a simple reaction between caprylic acid, a natural fatty acid, and ethanol. The result is a light, clear liquid that stays water-white when stored well. Because the process is straightforward and the raw materials are easy to source, Ethyl Caprylate sits at the more affordable end of a perfumer’s palette.
You will find it in many everyday scented goods, from fine perfume to shampoos, soaps, softeners and even scented candles. Thanks to its chemical stability and lack of added stabilisers, the material holds its quality for several years when kept sealed and cool. Most producers suggest using it within three to four years for peak freshness.
Its high renewable carbon content and ready biodegradability also make it an appealing choice for brands aiming at greener formulas.
Ethyl Caprylate’s Scent Description
This ingredient is usually grouped under the fruity family. On a fresh blotter the first impression is a juicy pineapple accord, quickly joined by crisp apple and ripe banana tones. Within a minute or two a gentle grape brandy twist shows up, adding a soft warmth that keeps the fruit from feeling candy-like.
The note sits firmly in the top zone of a fragrance, making its biggest impact during the opening stages. It flashes bright and happy, then blends into the heart within about 15 minutes. While its main sparkle is brief, a faint creamy fruitiness can still be detected an hour later if you press the blotter to the nose.
Projection is moderate, giving a pleasant halo without overwhelming nearby notes. Longevity is typical for a light ester: noticeable for the first half hour, then gradually fading yet lending a subtle support to other fruit facets for several more hours.
How & Where To Use Ethyl Caprylate
Perfumers reach for Ethyl Caprylate when they need an immediate burst of natural fruitiness that feels ripe rather than candy sweet. It slips easily into pineapple, apple or banana accords and can even round out grape or cognac effects thanks to its gentle brandy nuance. Used alongside green notes like hexenol or crisp aldehydes, it brightens the top of a composition and helps fruity themes feel freshly cut rather than canned.
Ethyl Caprylate also serves as a subtle blender. At trace levels it softens sharp citrus materials and adds a creamy undertone that smooths transitions between top and heart. Because it is slightly heavier than very short chain esters such as Ethyl Butyrate, it hangs around a little longer, making it a good choice when you want the fruit to linger past the first few minutes.
Typical inclusion sits between 0.05 % and 1 % of the concentrate, with Symrise advising an upper limit of 1 %. Below 0.1 % the note is airy and fresh. Move toward 0.5 % and the pineapple becomes vivid with a banana peel edge. Push it over 1 % and a fatty waxy tone can creep in, dulling brightness and overwhelming delicate florals. Always test across a dilution series to find the sweet spot.
The material behaves well in most product bases, from fine fragrance alcohol to shampoos and softeners. High pH soap and highly acidic cleaners can hydrolyse esters over time so longevity may drop in those matrices. If you need long shelf life in alkaline bars consider encapsulating or pairing with more stable fruity boosters.
Prep work is simple: predilute to 10 % in ethanol or dipropylene glycol for smelling and weighing, then add the required amount to your concentrate. Shake or stir thoroughly since the neat liquid can stratify for a moment before fully blending. Store the bulk drum tightly closed to keep the color water white and avoid oxidation.
Safely Information
While Ethyl Caprylate is considered low hazard, sensible precautions help keep the workspace safe.
- Always dilute before evaluation: create a 10 % solution so you can smell the material accurately and avoid nasal fatigue.
- Never sniff from the bottle: direct inhalation of concentrated vapors can irritate mucous membranes and skew your perception of the scent.
- Ensure good ventilation: work near a fume hood or open window to disperse airborne volatiles and reduce buildup in the air.
- Wear gloves and safety glasses: these basic barriers prevent accidental skin contact or eye splashes when handling the neat liquid.
- Health considerations: some aroma chemicals trigger irritation or allergic reactions on sensitive skin. People who are pregnant or breastfeeding should consult a medical professional before prolonged exposure. Short encounters with low levels are generally safe but extended handling or high concentration exposure can be harmful.
For complete peace of mind always consult the up to date safety data sheet supplied by your vendor and revisit it regularly as regulations evolve. Follow the current IFRA guidelines for maximum use levels in any finished product to ensure consumer safety and regulatory compliance.
How To Store & Dispose of Ethyl Caprylate
Good storage habits keep Ethyl Caprylate fresh and bright. A fridge set between 4 °C and 8 °C slows oxidation, yet a cool cupboard works fine as long as it stays out of direct sun and away from heaters. Steady temperatures help prevent unwanted color changes.
Choose amber glass or high grade HDPE bottles fitted with polycone caps. The soft liner forms a tight seal that limits air exchange. Dropper tops look handy but often leak vapor, so reserve them for short term test solutions only.
Try to keep bottles topped up. The less air space above the liquid, the slower it ages. When you decant into smaller vials, fill them close to the shoulder and close firmly. Label every container with the name, date of opening and any hazard icons so no one mistakes the contents.
Store predilutions upright in a tray or box to catch spills. Wipe threads after each use, then return the bottle to its dark home. Check stocks every six months. If the liquid turns yellow or develops off notes discard the batch rather than risk spoiling a formula.
Disposal is straightforward thanks to the material’s ready biodegradability. Small lab volumes can usually be mixed with plenty of warm soapy water and rinsed to drain if local rules allow. Larger batches should go to a licensed waste handler together with other non-halogenated organics. Never pour it onto soil or throw it in regular trash.
Summary
Ethyl Caprylate is a clear fruity ester that smells of pineapple, apple, banana and a hint of brandy. It lifts the top of fragrances, smooths citrus blends and adds realistic fruit flesh at levels up to 1 %. Light, inexpensive and largely renewable, it shows up in fine perfume, body care, cleaners and candles.
The note is vivid yet short lived so it pairs best with other boosters that carry the fruit into the heart. It stays stable in most bases but can hydrolyse in very alkaline soap. Because the raw materials are common the cost is low, making it a staple in many labs.
You can buy high purity Ethyl Caprylate in bulk from Symrise or other aroma suppliers. Hobbyists will find smaller amounts at online resellers that cater to independent perfumers and candle makers. Whether you run a large factory or a kitchen bench setup careful storage, smart dosing and clear labeling will let this cheerful ester shine in your next formula.
