A heavy, waxy long-chain aldehyde with a soft, slightly musky-fatty character reminiscent of warm beeswax and clean laundered fabric. Much less sharp than shorter aldehydes (C10-C12); it reads as a smooth, creamy skin-like nuance with a subtle soapy shimmer. Adds substantivity and a rounded fatty-wax dimension to musk and floral accords.AI · claude-opus-4-7
