Etymology

From German Kreosot in 1935, coined in 1832 by German natural philosopher Carl Ludwig, Baron Reichenbach, from Ancient Greek κρέας (kréas, “flesh”) + σωτήρ (sōtḗr, “preserver”) for its use as an antiseptic and meat-preservative. Creosote-bush named after its scent. By surface analysis, creo- + -sote.
