Benzoin Siam Essential Oil

Benzoin Siam Essential Oil (Styrax tonkinensis): Sweet Vanilla-Balsamic Resin Oil for Perfumery, Diffuser, Soap and Candles

Quick answer: Benzoin Siam Essential Oil is a solvent-extracted resinoid from the gum resin of Styrax tonkinensis, sold under the common name benzoin Siam essential oil. It has a sweet, warm, vanilla-like balsamic aroma and works as a long-lasting fixative in perfumery, diffusers, soaps, candles and balms. It is thick and dark, with a two year shelf life and COA and MSDS available on request. It comes in 100 ml and 500 ml bottles for home use and 1 kg to 25 kg packs for brands and bulk buyers.

Benzoin Siam Essential Oil is made from the natural gum resin that tree bark releases when it is cut. Unlike steam distilled oils, it is a resinoid obtained by solvent extraction, which is why it is thick, dark and rich in resin compounds. RV Organica’s Benzoin Siam Essential Oil is packed at our facility in Nimbri, Panipat, Haryana, and offered in sizes from 100 ml to 25 kg.

What is benzoin Siam essential oil and how is it made?

Benzoin Siam comes from Styrax tonkinensis, a tree grown in parts of Laos, Vietnam and Thailand. Growers cut incisions in the bark, the tree exudes a pale, sticky sap, and the sap hardens into resin. That resin is then dissolved in a solvent and the solvent is removed, leaving a thick, brown, aromatic resinoid. Because it is a resinoid rather than a distilled oil, it is sold under the trade name essential oil but behaves differently, being heavier, stickier and far more tenacious.

It should not be confused with Sumatra benzoin, which comes from a different tree, Styrax benzoin, and smells darker and more cinnamic. Siam benzoin is cleaner, sweeter and closer to vanilla. Its character comes mainly from coniferyl benzoate at 55 to 65 percent and benzoic acid at 10 to 20 percent, with benzyl benzoate at 1 to 6 percent and vanillin at 1 to 3 percent. The vanillin explains the sweet, creamy note, and the benzoic acid explains why the acid value is high.

What does benzoin Siam essential oil smell like?

Benzoin Siam smells rich, sweet and warm, with vanilla, caramel and soft chocolate notes over a powdery, balsamic base. It is smooth rather than sharp and lingers for a very long time. Perfumers value it as a base note and fixative, because it slows the evaporation of lighter, more volatile ingredients and rounds off rough edges in a blend.

How do you use benzoin Siam essential oil in a diffuser?

Because the resinoid is thick and may solidify below 20°C, warm the closed bottle gently in a bowl of warm water until it flows, then add a few drops to a diffuser. It gives a cosy, sweet and comforting atmosphere, especially in cooler months. Blend it with sandalwood essential oil for a creamy, woody mix or with frankincense essential oil for a warm, resinous one. For a dessert-like warmth, pair it with vanilla essential oil.

How do you use benzoin Siam essential oil in body oils, balms and soap?

Always dilute benzoin before it touches the skin. It dissolves in alcohol and fixed oils but not in water, so warm it gently and mix it into a carrier oil first. The right ratio depends on how much you are making and where it will be used, and our essential oil dilution calculator works it out for you. Once diluted, it adds a sweet, balsamic note to massage oils, balms, salves and body butters. In soap it brings a warm, lasting scent, though its brown colour can tint pale bases, so test a small batch first.

Can you use benzoin Siam essential oil in candles and perfume?

Yes. In candles, test a small batch first, because a thick resinoid can behave differently from a thin oil in wax. In perfumery it is a classic fixative and base note, central to amber, oriental, gourmand and incense-style compositions. It pairs well with rose, jasmine, patchouli, vetiver, myrrh, cedarwood, lavender, ylang ylang, clove bud and spice oils. For fragrance products, check the current IFRA standards for your product category before setting usage levels.

What are the specifications of benzoin Siam essential oil?

The resinoid has a specific gravity of 1.095, a relative density of 1.080 to 1.120, a refractive index of 1.500 to 1.530 at 20°C, a flash point above 101°C, an acid value of 80 to 120 mg KOH/g and moisture content of up to 0.1 percent. It is a viscous liquid to semi-solid, brown to dark brown, with a rich, sweet, balsamic odour. The shelf life is two years, and it is soluble in alcohol and fixed oils and insoluble in water.

How should you store benzoin Siam essential oil?

Keep the bottle tightly closed in a cool, dark place away from heat and direct sunlight. Cool storage may thicken or solidify the resinoid, which is normal. Warm the closed bottle gently in warm water before use rather than heating it directly. Stored well, it keeps its quality for the full two year shelf life.

Is benzoin Siam essential oil safe to use?

Benzoin Siam essential oil is for external use only. Do not ingest it. Always dilute it in a carrier oil before applying it to the skin, do a patch test first, and avoid direct sunlight on treated skin. Resinous materials and compounds such as benzyl benzoate can cause reactions in some people, so use it sparingly. Keep it away from children and pets, and consult a doctor before use if you are pregnant or nursing. This product is not intended to diagnose, treat, cure or prevent any disease.

Each batch is checked before dispatch, and a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS) are available for every batch, which most brands need for their records and compliance.
