What is Benzoin Resinoid Sumatra?

Benzoin Resinoid is a natural exudate from Styrax benzoin, harvested in Sumatra through bark incisions that yield aromatic resin droplets. Once collected, the raw resin is processed into a resinoid using solvents such as ethanol or benzyl benzoate (BB), creating a material with consistent texture and improved solubility for perfumery use. Its olfactory profile combines sweetness with warmth and subtle spice, making it a long-standing base note modifier and fixative.

Olfactory Profile and Perfumery Applications

Benzoin Resinoid functions as a base note and fixative, reinforcing the longevity of top and heart notes while enriching a formula’s depth with:

• Vanilla-balsamic warmth

• Slightly spicy amber tonality

• Soft smoky trails in drydown

It is frequently used in:

• Oriental fragrances: Adds roundness and warmth

• Gourmand compositions: Supports vanilla, caramel, and praline notes

• Amber bases: Boosts depth and richness

• Floral perfumes: Used in traces with lilac, heliotrope, or orange blossom

Common concentration ranges:

• Fine fragrance: 2–5%

• Soaps and lotions: 0.5–2%

• Incense or ceremonial uses: Up to 10%

Its ability to blend with natural oils and synthetics makes it indispensable for traditional and modern perfumery.
