In short

What Ozofleur smells like
IFF's description, as The Good Scents Company records it, is ozone-like, wet metallic, clean and effervescent. The Good Scents Company's own evaluation of a 10% solution in dipropylene glycol gives fresh outdoors, green bell pepper, ozone and marine; other listings it quotes call it aldehydic, ozonic, green and fruity.

What makes Ozofleur distinctive
Wet metal and open air rather than sea spray: ozone with a mineral, metallic edge.
How Ozofleur is used
Used for fresh-air, ozonic and marine effects in aquatic, solar and fresh floral accords.
Typical role: modifier (used in small amounts to change the character of a blend).
How Ozofleur differs from similar materials
- Pinoacetaldehyde
- Pinoacetaldehyde carries pine needles with its sea air; Ozofleur is ozone and wet metal, without the pine.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
