n. See Creosote. [ 1913 Webster ]

n. [ Gr. kre`as, gen. kre`ws, flesh + sw`zein to preserve. ] (Chem.) Wood-tar oil; an oily antiseptic liquid, of a burning smoky taste, colorless when pure, but usually colored yellow or brown by impurity or exposure. It is a complex mixture of various phenols and their ethers, and is obtained by the distillation of wood tar, especially that of beechwood. [ 1913 Webster ]

☞ It is remarkable as an antiseptic and deodorizer in the preservation of wood, flesh, etc., and in the prevention of putrefaction; but it is a poor germicide, and in this respect has been overrated. Smoked meat, as ham, owes its preservation and taste to a small quantity of creosote absorbed from the smoke to which it is exposed. Carbolic acid is phenol{ 1 } proper, while creosote is a mixture of several phenols. [ 1913 Webster ]

Coal-tar creosote (Chem.), a colorless or yellow, oily liquid, obtained in the distillation of coal tar, and resembling wood-tar oil, or creosote proper, in composition and properties. [ 1913 Webster ]

v. t. [ imp. & p. p. Creosoted p. pr. & vb. n. Creosoting. ] To saturate or impregnate with creosote, as timber, for the prevention of decay.

. A shrub (Covillea mexicana) found in desert regions from Colorado to California and southward through Mexico. It has yellow flowers and very resinous foliage with a strong odor of creosote. [ Webster 1913 Suppl. ]
