Descriptions
Description
Rose Oxide is a solid floral-rose with faint sweet-fruity touches. It isdiffusive and penetrating.
Odour (PerfumersWorld)
Can aid in creating a realistic rose but it is very stout despite some ofits linalool freshess. It is sometimes described as a “gassy-green” or “hardgreen” floral with lots of lift but poor longevity. Certain materials have aless gassy more 'bread-like' topnote (Rose de Mai) which is warmer and morepleasant than the 'gassy' type of odor

Synaesthesia (PerfumersWorld)
A rose crawls out of the bouquet and chastises you with abaritone voice
Comment (FraterWork)
Rose Oxide (Racemic) opens with an almost aggressive metallic freshness that
cuts through compositions like a blade. This sharp, gassy-green character
delivers the unmistakable scent of rose stems being snapped in half. You'll
recognise its penetrating quality immediately—that bright, almost electrical
sensation that makes roses feel alive rather than preserved.
This material transforms predictable rose reconstructions into dynamic,
three-dimensional experiences. Use it when you need compositions to project
powerfully from the bottle, creating that crucial first impression. Combine Rose
Oxide with traditional rose alcohols like citronellol and geraniol to build
complexity, or pair it with black pepper for unexpected vibrancy that modern
perfumery demands.
Deploy Rose Oxide with extreme restraint—overdosing creates harsh, unpleasant
effects that dominate rather than enhance. Working concentrations rarely exceed
1% in your concentrate, with trace amounts often sufficient for remarkable
transformation. Its poor tenacity makes it purely a top-note material,
disappearing within hours but leaving behind space for your heart notes to
bloom.

ROSE OXIDE VARIATIONS
Rose Oxide comes in three commercially significant forms, each offering distinct
olfactory profiles and potency levels.
Racemic Rose Oxide (this product) contains approximately seventy-five percent
cis isomers mixed with trans forms, delivering strong rose-geranium character
with pronounced metallic-green edges and good diffusion.
High Cis Rose Oxide elevates cis content above ninety percent, resulting in
cleaner, brighter red rose character with significantly reduced metallic
sting—it's easier to dose and exceptionally diffusive.
Laevo Rose Oxide isolates the pure minus-cis isomer, offering unmatched potency
(one-hundred times stronger than racemic) with softer, more radiant floral
character, enhanced greenness, and sublime diffusion—though its extreme strength
and premium price make it challenging to work with for everyday formulations.
