What Is Delphol Hc?
Delphol Hc is a synthetically produced aroma chemical belonging to the broad family of jasmine-type materials. It was first developed by DSM-Firmenich, the same house that created Hedione in the late 1950s. Today you will also find comparable versions offered by independent suppliers who purchase it in bulk or reproduce the molecule under a generic name.
The material is obtained by a carefully controlled chemical process that uses by-products from the large-scale Hedione manufacture. Using what would otherwise be waste fits neatly into modern ideas of upcycling and green chemistry. The final product is a clear mobile liquid at room temperature with a moderate flash point, making it straightforward to handle in most fragrance labs.
Delphol Hc is classed as readily biodegradable and shows excellent formula stability, so it can be used in fine fragrance through to household cleaners without breaking down or discoloring. Its shelf life, when stored in a tightly closed container away from heat and direct light, is typically around two to three years before noticeable quality drift occurs.
In the broader raw-material marketplace Delphol Hc sits in the mid-price band. It is not a rare or captive ingredient, yet the molecule gives a refined floral effect that perfumers value. As a result it appears in many commercial creations aiming for a modern light jasmine nuance.
Delphol Hc’s Scent Description
Perfumers place Delphol Hc in the floral family. On a fresh blotter the first impression is a gentle jasmine note backed by a soft, milky fruitiness. Within seconds a hint of celery leaf peeks through, lending a crisp green facet that keeps the material from feeling overly sweet. As the scent opens further, echoes of magnolia petal and hot tea emerge, creating an airy bloom rather than a dense bouquet.
Perfumery often divides a fragrance into top, middle and base notes. Tops are what you notice in the first few minutes, middles form the heart that lasts for several hours, bases linger longest on skin or fabric. Delphol Hc sits firmly in the middle zone. It appears after the more volatile citrus or herb notes drift off, then bridges smoothly to the deeper woods or musks underneath.
Projection from a formula is moderate. It radiates enough to give a clean floral aura without feeling overpowering. Longevity is impressive for a light floral: on a blotter a detectable trace can still be smelled after forty-eight hours, and on skin it often continues into the next day depending on dose and supporting ingredients.
How & Where To Use Delphol Hc
Perfumers reach for Delphol Hc when they want to build a light yet persistent jasmine effect without crowding the formula. It is most often slotted into the heart of white floral accords where it rounds off harsher indolic materials and stretches the bloom of natural absolutes. In a modern magnolia or tea accord it supplies the creamy petal nuance that keeps the composition airy.
Typical use levels run from a trace in delicate colognes up to around 5 % in richer eau de parfums. At 0.1 % it behaves like a softening modifier, adding milkiness that is almost invisible yet clearly missed if removed. Between 1 % and 3 % the jasmine character becomes evident and blends smoothly with hedione, linalool or benzyl acetate. Above 4 % the green celery facet asserts itself, which can be interesting in herbal or spa-style scents but feels distracting in classic bouquets.
Delphol Hc performs well in functional products thanks to its stability toward alkaline cleaners, bleach and high wash temperatures. It can appear in shampoos, soaps, fabric softeners and candles without discoloring or breaking down. The downside is that its subtle profile can be drowned by strong detergency odor, so backup boosters like hedione HC or jasmine absolute are often added.
Over-dosing risks a flat, slightly fatty note that muddies the mid accord and exaggerates the green edge. Because the molecule lingers on skin and strip, a heavy hand can also mask later base notes. Start with a 10 % solution in ethanol or di-propylene glycol, evaluate at 0.5 % total concentrate and adjust upward only after stability and odor checks.
No special activation is required before use, but a quick heat-and-cool cycle can help when blending into solid wax or cold process soap. Always note its 95 °C flash point when planning candle pours or hot compounding so you avoid unnecessary vapor loss.
Safety Information
Always dilute Delphol Hc before evaluating it. Avoid direct sniffing from the bottle and work in a well ventilated area to prevent inhaling concentrated vapors. Wear nitrile gloves and safety glasses to keep the liquid away from skin and eyes.
Like many aroma chemicals it may cause irritation or an allergic response in sensitive individuals. Those who are pregnant or breastfeeding should first seek medical advice before prolonged handling. Short low-level exposure is generally considered safe yet repeated high-concentration contact can be harmful so monitor air quality and avoid spills.
Store the material in a tightly closed amber bottle, keep it away from heat sources and direct sunlight and segregate it from strong acids or oxidizers. Spills can be wiped with absorbent material then disposed of according to local chemical waste regulations.
Always refer to the most recent Safety Data Sheet supplied by your vendor, as revisions are common. Follow IFRA guidelines for maximum dosage in each product category to ensure legal and consumer safety compliance.
How To Store & Dispose of Delphol Hc
Delphol Hc keeps its best character when stored in a cool dark place away from direct sunlight and heat. A dedicated fragrance fridge at 5 °C can stretch shelf life yet a stable basement cabinet also works if temperatures stay below 25 °C.
Use glass or aluminum bottles fitted with polycone caps because these create an airtight seal. Dropper bottles let air creep in and should be avoided for long term holding. Whenever possible top up containers or decant into smaller ones so the headspace stays minimal and oxidation slows.
Label every vessel with the material name batch date and essential hazard symbols. Include the flash point of 95 °C and note any personal protective gear required for handling. Clear labeling prevents mix-ups and speeds any emergency response.
Keep the storage area dry and separate from strong acids bases and oxidizers. Set a spill tray under the bottles, stock absorbent pads nearby and ventilate the room so vapors never build up.
When it is time to dispose of leftovers remember Delphol Hc is readily biodegradable. Small rinse residues can usually go to the municipal drain with plenty of running water unless local rules forbid it. Larger volumes should be collected in a sealed drum and handed to a licensed chemical waste contractor. Used wipes and empty bottles must also follow local hazardous waste guidelines.
Summary
Delphol Hc is a liquid aroma chemical from DSM-Firmenich that offers a light jasmine scent laced with creamy fruit and a crisp celery hint. It sits in the heart of a perfume where it widens white floral notes and brings smooth staying power for up to two days on a blotter.
The molecule is popular because it is stable across fine fragrance shampoo soap and cleaning formulas yet it costs far less than natural jasmine. Its subtle profile means you must dose with care; too much flattens the blend and pushes out later base notes.
Storage is simple; keep it cool dark and tightly sealed. The ingredient is readily biodegradable but still needs mindful disposal for larger batches.
You can buy Delphol Hc in bulk straight from DSM-Firmenich or pick up smaller hobby sizes from specialty resellers and generic aroma suppliers. Either route gives you access to a versatile floral helper that lifts modern compositions without stealing the spotlight.
