Descriptors

A powerfully diffusive fatty aldehyde with a distinctive oily, fish-skin character reminiscent of cod liver oil and fresh cucumber peel. At trace levels it reads as green, watery and slightly melon-like, but neat it is aggressively fishy and rancid-fatty. Used in ultra-low ppm doses for marine, melon and dairy effects.AI · claude-opus-4-7
