 pet·ro·la·tum /ˌpɛtrəˈletəm, ˈlɑt-/ 名詞

From: Webster's Revised Unabridged Dictionary (1913)

 Pet·ro·la·tum n. Chem. & Pharm. A semisolid unctuous substance, neutral, and without taste or odor, derived from petroleum by distilling off the lighter portions and purifying the residue.  It is a yellowish, fatlike mass, transparent in thin layers, and somewhat fluorescent.  It is used as a bland protective dressing, and as a substitute for fatty materials in ointments.
 Note: ☞ Petrolatum is the official name for the purified product.  Cosmoline and vaseline are commercial names for substances essentially the same, but differing slightly in appearance and consistency or fusibility.
