What Is Cassie Abs Type Nat?
Cassie Abs Type Nat is a specialty aroma ingredient designed to replicate the fragrant twigs and blossoms of the cassie shrub, better known to gardeners as Acacia farnesiana. It comes from DSM-Firmenich, one of the largest suppliers of perfumery materials worldwide. While DSM-Firmenich originated the formula, comparable “cassie absolute type” blends are offered by several other ingredient houses, each with its own minor tweaks.
Rather than a single raw extract, this material is a carefully balanced mixture of natural absolutes, isolates and a few protected captive molecules. The blend captures the character of true cassie absolute while improving consistency and supply. Twigs and flowers are first extracted, then the aromatic fraction is refined and combined with complementary components. The result is a smooth, ready-to-use liquid that behaves much like a natural absolute but with greater stability and batch-to-batch uniformity.
At room temperature the product pours as a thick, slightly sticky liquid colored a deep olive green. Its viscosity eases with gentle warming, an advantage when weighing small amounts in the lab. Cassie Abs Type Nat is already popular in fine fragrance work and is steadily gaining ground in functional products such as shampoo, shower gel and candles thanks to its good stability in soap bases and detergents.
Under normal storage conditions you can expect a shelf life of roughly two to three years before subtle oxidation starts to dull its brightness. Perfumers tend to regard it as a mid-priced floral ingredient: not prohibitively costly, yet still special enough that it is dosed with care rather than poured with abandon.
Cassie Abs Type Nat’s Scent Description
Most perfumers file this ingredient in the broad floral family. On a scent strip it first greets the nose with airy mimosa pollen crossed with a touch of honeyed warmth. Within minutes a spicy-green facet peeks through, evoking fresh twig shavings and crushed violet leaves. As the strip dries further, a soft woody undertone surfaces, giving the whole accord a rounded, almost suede-like depth.
In the classical top-middle-base framework cassie sits firmly in the heart. It rises fairly quickly yet stays present after brighter top notes have faded, knitting the opening to the base. Although not a base note, it does leave a subtle imprint well into the drydown, especially when reinforced by other woody or balsamic materials.
Projection is moderate, lending a diffusive floral halo without overwhelming neighboring notes. Longevity on paper is impressive for a floral heart, easily lasting eight hours and often detectable the next morning in closed notebooks or wallets where the blotter was tucked away.
How & Where To Use Cassie Abs Type Nat
Perfumers reach for Cassie Abs Type Nat when they need a soft yet lasting floral bridge. Its honeyed mimosa vibe fills the gap between bright top notes and deep base materials, giving a creamy link that feels natural. In a classic spring bouquet it can replace part of real cassie absolute, lowering cost while keeping character. It also lifts violet, heliotrope or orange blossom themes without stealing the spotlight.
A typical inclusion sits between traces and 2 percent in fine fragrance concentrates. Light body sprays may accept up to 5 percent, while soaps or detergents often work best below 0.5 percent so the floral tone does not clash with cleansing bases. At 0.1 percent the note reads as a gentle pollen dusting. Push it above 3 percent and the green stem facet turns earthy and can overshadow delicate accords.
The ingredient shines in powdery florals, skin scents, fougères and soft orientals. It partners well with benzoin, sandalwood, iris or subtle musks. Uses are less convincing in sharp citrus colognes or ultra fresh marine blends where its warmth feels out of place. Candles benefit from its tenacity though the wax matrix may mute some green nuances.
Because the liquid is thick, most labs pre dilute it to 10 percent in ethanol or dipropylene glycol for easy weighing. A gentle warm water bath loosens the viscous mass before pipetting. Blotter tests should be done at several strengths to judge how the floral tone shifts with concentration. Keep in mind that a little goes a long way; overuse can flatten a composition and leave an oily feel in functional bases.
Safely Using Cassie Abs Type Nat
Dilution is key. Always create a working solution before smelling or adding to a formula. Avoid direct sniffing from the bottle since high vapour hits can dull your sense of smell and irritate membranes. Work in a well-ventilated space so airborne particles disperse quickly. Gloves and safety glasses stop accidental skin contact or splashes.
Like many perfumery materials this blend can provoke skin irritation or rare allergic reactions, especially when handled neat. Anyone who is pregnant or breastfeeding should check with a medical professional before extended work sessions. Short exposure to low concentrations is generally safe yet long or repeated handling at full strength can be harmful.
Store the bottle tightly capped in a cool spot away from light to keep oxidation low. Wipe threads after use so the cap seals well and the thick liquid does not gum up. Dispose of waste solutions and wipes through local chemical waste channels, never down the sink.
For the latest limits and hazard codes always review the supplier’s Material Safety Data Sheet and update your records when a new revision appears. Follow current IFRA guidelines to set maximum dosage in each product type and adjust your formula if those rules change.
How To Store & Dispose of Cassie Abs Type Nat
Cassie Abs Type Nat holds up well at normal room temperature yet a cool dark cabinet slows oxidation and colour change. If you have the space a dedicated fragrance fridge set between 4 °C and 8 °C can stretch the shelf life even further. Whichever option you choose keep the bottle away from direct sunlight and heaters so the thick liquid stays stable.
Air contact is the main enemy of this material. Decant it into the smallest practical bottle so the headspace stays low and top up working bottles when levels drop. Fit them with polycone caps because the insert squeezes against the neck and forms a tight seal. Dropper tops look convenient but they leak vapour and invite clogging as the viscous oil dries.
Label every container with the full name, date of receipt, strength of any dilution and the main hazard codes. Clear labels prevent mix ups, speed up inventory checks and help first responders in an emergency. Store dilutions upright in a secondary tray so any drips are contained and easier to wipe.
When a batch finally turns cloudy or loses its bloom do not pour it down the sink. The concentrate is oily and only partly biodegradable so it can stress water treatment plants. Collect spent material in a sealed container then hand it to a licensed chemical disposal service or community hazardous waste drop off. Paper wipes and empty bottles should be triple-rinsed with solvent, dried, bagged and disposed of according to local regulations.
Summary
Cassie Abs Type Nat is a ready blended specialty from DSM-Firmenich that mimics costly cassie absolute with impressive faithfulness. It smells of creamy mimosa touched by honey, green stems and a whisper of wood, sitting between a heart and a base note in a formula. Perfumers prize it for filling floral gaps, extending delicate bouquets and lending powdery warmth to soaps, candles and fine fragrance.
The accord enjoys steady popularity because it offers natural character without the price swings tied to botanical harvests. It remains fairly stable for two to three years when stored well although thick texture and possible oxidation need watching. Cost is higher than basic aroma chemicals yet often lower than true absolutes so many brands see it as good value for the effect it delivers.
Commercial buyers can source it straight from DSM-Firmenich or authorised distributors in kilogram lots. Smaller labs, hobbyists and indie makers usually pick up decanted portions from trusted resellers or explore generic equivalents sold under similar names. However you obtain it, treat it with care, dose it with restraint and it will reward you with a long-lasting floral glow that few other materials provide.
