Iso Eugenol (10% in DPG) is a pre-diluted form of the warm, spicy-floral aroma chemical Iso Eugenol, known for its clove-like, sweet, and slightly woody scent with a soft floral nuance. Used widely in oriental, carnation, spicy floral, and ambery perfumes, it brings volume, warmth, and longevity to floral heart notes and balsamic bases.

This 10% dilution in DPG (Dipropylene Glycol) makes it ready for use in attars, oil-based perfumes, body sprays, solid perfumes, and classic floral-oriental blends.

Iso Eugenol is perfect for reinforcing carnation, ylang-ylang, rose, and cinnamon accords, and blends well with Cinnamyl Alcohol, Rose Wardia, and Tolu Balsam.

SCENT DESCRIPTION : IsoEugenol opens with a sharp, medicinal clove spice that quickly softens into a warm, creamy floral warmth. The mid-character reveals a carnation-like quality with a hint of sweet woodiness underneath. As it dries down, it settles into a smooth, long-lasting spicy-woody base with subtle incense depth. It is less harsh than eugenol and carries a rounder, more diffusive quality on skin.

⚠️ IsoEugenol is a recognized skin sensitizer and is classified as a restricted fragrance allergen under EU Cosmetics Regulation and IFRA guidelines. Always calculate final concentration in finished product, not in fragrance concentrate.
⚠️ At concentrations above IFRA limits in leave-on products, risk of allergic contact dermatitis increases significantly. Do not exceed stated limits.
⚠️ Must be declared on EU/UK cosmetic labels if present above 0.001% (rinse-off) or 0.001% (leave-on) in finished product.

METHOD 1 — DIRECT ADDITION IN ALCOHOL BASE
Dissolve IsoEugenol directly in perfumer's alcohol (IPM or ethanol 95%) at your calculated concentration. Because its usage rate in fine fragrance is very low (max 0.02%), pre-dilute in ethanol at 10% concentration for easier accurate dosing at the bench. This avoids overdosing errors.

METHOD 2 — ATTAR AND CARRIER OIL BLENDING
In attar or oil-based perfumes, IsoEugenol blends readily with fixed oils and fractionated coconut oil. Combine with sandalwood base first, then layer rose, oud, or musk accords on top. Its warmth anchors the entire composition and rounds off sharp synthetic notes.

METHOD 3 — SOAP AND HOME FRAGRANCE APPLICATIONS
For soap and candle use, add IsoEugenol to your fragrance premix before incorporating into base. It is heat stable up to its flash point, making it suitable for hot-process soap and candle pouring temperatures. In candles, use in combination with woody and resinous materials for full oriental compositions.

BEST PAIRINGS

Rose Absolute/Rose Otto : Creates a classic carnation-rose accord; soft, romantic, and deeply oriental
Oud/Agarwood Oil : Amplifies the resinous, incense-like depth; essential pairing in attar work
Sandalwood (Mysore/Synthetic): Adds a creamy, smooth base that rounds and softens the clove edge
Ylang Ylang : Natural harmony since both share IsoEugenol in their chemistry; rich floral
Vetiver : Earthy-smoky contrast that grounds the spice and adds sophistication
Benzyl Benzoate : Excellent diluent and synergistic carrier that extends diffusion
Amyl Eugenol : Shares spicy clove family; layering creates complex, multi-faceted spice accord
Musk Ketone / Habanolide : Soft musk base lifts the clove character and adds modern longevity

AVOID
Avoid combining at high concentrations with other strong sensitizers such as cinnamaldehyde or hydroxycitronellal, as combined sensitization risk in leave-on products compounds significantly.

💡 To build a warm, spicy-floral perfume heart 🌺, use 1–3% Iso Eugenol (10% in DPG) in your oil-based perfumes or vintage-style attars.

🌹 Combine with Rose Wardia for a velvety floral warmth, and Cinnamyl Alcohol to push a bold carnation or cinnamon-clove edge.

🕯️ Add Tolu Balsam to create a traditional oriental amber base that feels nostalgic and rich.

🔄 Stir or shake before use for uniform distribution in oil or ethanol systems.
