Iso E Super Type OTNE Crystal – Woody-Amber Perfumery Molecule, Fixative, Liquid

OTNE Crystal (Iso E Super type) — Crystal-Clear, High-Purity Woody-Amber Molecule (Liquid)

OTNE Crystal is a high-purity grade of OTNE (Iso E Super type) with a crystal-clear, transparent aroma — one of the most iconic woody-amber molecules in perfumery. It is supplied as a clear, slightly viscous liquid.

Please note: "Crystal" is our commercial name — it refers to the crystal-clear purity and transparency of the aroma (a clean, smooth, transparent scent), not to a solid or crystalline form. The product is supplied as a liquid.

This refined grade is known for its expansive, airy, voluminous diffusion, creating a sense of depth, smoothness, and three-dimensional movement in a fragrance. The molecule forms a soft woody-amber aura, enhances surrounding notes, and adds clarity, transparency, and a silky atmospheric quality to any composition.

Why Perfumers Choose OTNE Crystal (Iso E Super type)
• Crystal-clear purity for a smooth, clean aroma
• Expansive, voluminous diffusion that creates an "aura around the skin"
• Clean woody-amber profile without dusty, sour, or harsh nuances
• Well suited to niche, artisanal, minimalist and skin-scent perfumery
• Enhances longevity, depth, and diffusion of finished fragrances
• Works harmoniously in both complex formulas and ultra-minimalist blends
• Widely used by perfumers in Europe, the USA, and Asia

OTNE Crystal is valued for its ability to "open up" a fragrance, add dimension, and amplify spatial perception without overshadowing other ingredients.

What is OTNE?
OTNE (Tetramethyl acetyloctahydronaphthalenes, CAS 54464-57-2) is a synthetic woody-amber aroma molecule first introduced in the 1970s, also offered under trade names such as Iso E Super (this product is an Iso E Super type / OTNE). It has become one of the most widely used ingredients in perfumery, prized for its smooth, expansive diffusion and its ability to lend volume, radiance and a velvety woody-amber character to a composition. This crystal-clear grade is a cleaner, more refined interpretation, chosen by creators who prioritise airy smoothness and nuanced diffusion.

SHIPPING & DELIVERY TIMES
Orders are shipped from Germany. Order processing — from placement to handover to the postal service — takes 1–2 business days, excluding weekends, and never exceeds the processing time stated on Etsy.
All parcels are sent via the German postal carriers DHL or Deutsche Post with a tracking number provided. Once your order ships, you will receive the tracking number and can follow your parcel.
Please note that the delivery times shown on Etsy are estimates. They are calculated automatically and depend on the postal and customs services, so the actual delivery time may vary. What we are responsible for — and fully guarantee — is handing your order over for shipment within the stated processing time.
The speed of the postal carriers (DHL and others) and customs is beyond our control. If anything unusual happens with a parcel — a delay, a loss, or a customs query — we step in and help: we open an inquiry, file the necessary claims, and see the matter through to a resolution.

CANCELLATIONS & RETURNS
If a parcel is returned to us because of an incorrect or incomplete address, the recipient's absence, or failure to collect it from the post office in time, we do not re-ship the same order. The cost of the item is refunded; a new shipment requires placing the order again.
If a buyer cancels an order that has already been shipped, the cost of the item is refunded once the item has been returned to us. Shipping costs are not refunded in this case.
For any return, the cost of the item is refunded. Shipping costs (both outbound and return postage), as well as any taxes and customs duties, are non-refundable.
If the sealed packaging has been opened, the item may not be eligible for return for reasons of hygiene (§ 312g (2) no. 3 of the German Civil Code, BGB). This applies to opened, used, or partially consumed materials. Your statutory consumer rights remain unaffected.

PAYMENTS & REFUNDS
All payments and refunds are processed through Etsy's payment system. The processing times for payments and refunds are determined by the platform. We initiate a refund on our side right away, but the time it takes to appear is governed by Etsy's rules.
