Airlux Signature Aroma Oil No. 034 Opus Noir

Opus Noir is a amber vanilla designed for the way a room wears a fragrance — not the way skin does. It opens with pear, pink pepper, orange blossom, settles into a heart of coffee, jasmine, bitter almond, and lands on a base of vanilla, patchouli, cashmere wood, cedarwood that holds long after diffusion stops.

Designed for spaces where atmosphere is part of the design. The composition is calibrated for even ambient projection rather than skin-close radiance — the room reads the scent at consistent intensity from any corner.

Opus Noir is for you if

• You design your space deliberately and want the air to be part of that design.
• You want the room to feel composed and intentional.
• You prefer atmospheric depth over bright energy.
• You read ingredient lists and want to know what you're putting into your air.

Opus Noir is HumanSafe™ Verified with a Product Safety Score of A-. HumanSafe™ is an independent, science-based safety framework that scores ingredient safety at realistic use levels — not worst-case theoretical exposure, not fear-based ingredient blacklists.

What "application-aware" scoring means

The same ingredient is scored differently depending on whether it appears in a skin-contact product, a heated diffuser, or a cold-air ambient diffuser — because the actual exposure route changes the risk.

As of May 2026, Airlux is the only US-market luxury ambient scenting brand that publishes per-ingredient safety scores (INCI + CAS + concentration) with application-aware methodology.Last competitive audit: May 2026.
