The term is often used for the simplest of the class, ethylene glycol (1,2-ethanediol). Propylene glycol (1,2-propanediol), much like ethylene glycol but not toxic, is used extensively in foods, cosmetics, and oral hygiene products as a solvent, preservative, and moisture-retaining agent.

甘醇一词，通常表示这种化合物中最简单的乙二醇(亦称1,2-乙二醇)。丙二醇(亦称1,2-丙二醇)和乙二醇类似但前者无毒，广泛用于食品、化妆品和口腔卫生品中作溶剂、防腐剂和保湿剂。
