Calone
Aroma Chemical Base Note CAS 28940-11-6
Powerful marine and ozonic with a fresh watermelon coolness and a clean, slightly green floral edge. The defining sea breeze note of 1990s aquatics, it is intensely diffusive and used in small amounts, revealing a mineral, oyster like facet at higher levels.

Both tenacity figures are blotter life. The two labs use different evaluation protocols, so the numbers are not directly comparable — read them as two independent readings, not as a contradiction.
