What Is Benzoin Siam Res 50 Dipg?
Benzoin Siam Res 50 Dipg is a liquid aromatic extract derived from the gum of the Styrax tonkinensis tree. DSM-Firmenich markets this particular grade, yet similar versions are offered by other aroma suppliers under different trade names. The 50 in the title signals the dilution level in dipropylene glycol, which keeps the resin easy to pour and blend.
Production starts with a gentle solvent wash of the raw gum, giving a thick resinoid. A second cleaning step removes waxes and heavy residues, leaving a polished material with consistent scent strength. The result is a pourable golden-brown liquid that stays fluid even in a cool studio.
Perfumers reach for Benzoin Siam often because its warm vanilla-balsamic character fits both classic and modern briefs. It appears in fine fragrance, candles, soaps and household care thanks to good stability across many formula types. When stored in a tight drum away from light and heat it keeps its quality for roughly three to four years before the top sparkle starts to fade.
Cost wise it sits in the moderate bracket. It is not a budget filler yet far from the most lavish naturals, which lets creative teams use it generously without wrecking a cost target.
Benzoin Siam Res 50 Dipg’s Scent Description
This ingredient lives in the balsamic family of smells. Off a blotter it opens with a sweet velvety cloud that feels like vanilla syrup touched with soft cinnamon and faint almond. Within minutes a gentle spicy edge appears, hinting at clove while never turning sharp. As the blotter dries the scent deepens into creamy amber, joined by a whisper of warm wood smoke that lingers soothingly.
In perfumery we talk about top, middle and base notes. Tops are the first impression, middles shape the heart of a perfume, bases are the long lasting trail. Benzoin Siam Res 50 Dipg sits firmly in the base group. It arrives quickly enough to support the heart yet remains detectable long after brighter notes have vanished.
Projection is moderate. It will not overpower a room yet provides a comforting aura close to the skin or fabric. Longevity is solid, often holding on for eight hours on a blotter and even longer when anchored by other resins or woods in a full formula.
How & Where To Use Benzoin Siam Res 50 Dipg
Perfumers reach for Benzoin Siam Res 50 Dipg when they want a gentle balsamic sweetness that rounds out sharp notes and adds lasting warmth. Its vanilla caramel heart slips easily into amber accords, oriental bases, gourmand blends and even certain fougères that need a creamy undertone. Because it is already thinned in dipropylene glycol, it blends quickly with both alcohol and oil systems, saving valuable bench time.
Typical usage sits anywhere from a trace up to about 5 percent of the concentrate. At very low levels it simply softens the formula, giving a subtle cushion behind top notes. From 1 to 2 percent the almond and cinnamon suggestions become clearer, weaving into tonka, vanilla, labdanum or coumarin for a fuller amber effect. Above 3 percent the material can dominate, reading intensely resinous and slightly medicinal, so restraint is wise unless a pronounced balsamic theme is desired.
Its odor profile shifts with concentration. Dilute doses smell milky and vanillic, while heavier doses reveal smoky phenolic edges. Overuse can flatten bright florals, muddy citrus and leave a cloying aftertaste in functional products like detergent. A light touch keeps the blend feeling plush rather than sticky.
Thanks to natural fixative qualities, Benzoin Siam extends longevity of volatile notes and acts as a bridge between mid and drydown stages. Layer it with opoponax for a classic amber chord, with patchouli for a chocolate nuance, or with spices such as cardamom for a chai-like finish. It is less effective in crisp colognes where transparency matters, and in high pH soap bases an added antioxidant may be needed to prevent color darkening.
Preparation is simple: shake the drum to redisperse any settled resin, then weigh directly into the perfume concentrate. If the liquid thickens in cool weather gently warm the container in a water bath below 40 °C. Further dilutions to 10 percent in ethanol can make fine adjustments easier when working at trace levels.
Safely Using Benzoin Siam Res 50 Dipg
Dilution is key when evaluating any fragrance raw material. Always prepare a working solution before smelling and avoid direct sniffing from the bottle. Conduct all bench work in a well ventilated space to prevent inhaling concentrated vapors. Gloves and safety glasses protect skin and eyes from accidental splashes.
Like many resins Benzoin Siam can trigger irritation or allergic responses in sensitive individuals. If you are pregnant or breastfeeding consult a medical professional before handling. Short handling sessions with low concentrations are generally considered safe but long or repeated exposure to undiluted material can lead to respiratory or dermal discomfort.
Clean any spills promptly with absorbent paper then wash the surface with mild soap. Contaminated wipes should be sealed and discarded according to local regulations. Should the material contact skin rinse with plenty of water and seek medical advice if redness persists.
Always reference the latest safety data sheet from your supplier and review it regularly as updates occur. Follow current IFRA guidelines for maximum use levels in finished goods to ensure consumer safety and regulatory compliance.
How To Store & Dispose of Benzoin Siam Res 50 Dipg
Keep Benzoin Siam Res 50 Dipg in a tightly closed amber glass or metal container placed in a cool dark cabinet away from heat sources and direct sunlight. Refrigeration is not essential yet it can slow oxidation and prolong the rich balsamic character, especially if the bottle will sit for more than a year.
Use polycone lined caps that create a tight seal and resist resin seepage. Dropper tops often let air creep in and should be avoided. After pouring material into a working bottle top up the container with inert gas or add glass marbles so the remaining headspace is minimal. Less oxygen means less chance of color shift or off notes.
Label every container clearly with the full ingredient name, dilution strength, date opened, batch number if supplied and any hazard pictograms required by local law. Periodically check older stock for cloudiness or sediment that can hint at degradation.
If a spill occurs absorb the liquid with sand or paper towel then wash the area with warm soapy water. Small residues on glassware rinse out easily with ethanol followed by detergent.
Dipropylene glycol is readily biodegradable while the natural resin portion breaks down more slowly. Never pour bulk quantities into drains or soil. For larger volumes mix with an inert absorbent, seal in a labeled drum and hand over to a licensed waste contractor. Hobby scale leftovers can usually be taken to a municipal household hazardous waste facility. Empty bottles should be triple rinsed before recycling when regulations permit.
Summary
Benzoin Siam Res 50 Dipg is a fifty percent solution of Siam benzoin resin in dipropylene glycol that arrives as an easy pouring amber liquid. It smells warmly balsamic with vanilla, caramel and faint almond facets backed by a touch of cinnamon.
Perfumers use it as a base note to anchor amber accords, sweeten gourmands or give soft depth to orientals. It fixes volatile notes, blends without fuss and sits at an accessible mid range price which explains why both artisan and global brands keep it on the bench.
The material stays stable for two or more years when stored cool and well sealed though refrigeration extends shelf life further. Costs remain reasonable yet its scent is specific so overdosing can weigh down light compositions.
Commercial buyers can source Benzoin Siam Res 50 Dipg directly from DSM-Firmenich or comparable dilutions from other major aroma suppliers. Smaller volumes for testing and hobby work are widely sold by specialty resellers and online fragrance ingredient shops, making this classic balsamic note within reach for projects of any scale.
