宝洁公司生产甘油已超过150年的历史，共拥有三个系列的产品，即Superolk、Stark和Moonk。其中Superolk是具美国药典、美国食典、欧洲药典、清真洁食等多项认证，主要用于制药、食品及个人护理领域，Superolk的纯度为99.7％而Stark的纯度为96.7％。Moonk系列是由宝洁委托当地厂家按照宝洁的要求代工的产品，不具备食品认证及欧洲药典认证，杂质含量相比Superolk、Stark来得稍微高一些，但同样具备99.7％的纯度，并符合USP标准，适用于一般的工业生产。 Superolk系列共有四个品种： Superol K        Glycerine 99.7% USP/FCC (Kosher) Superol KNP      Glycerine 99.7% USP/FCC (Kosher Not for Passover) Superol V        Glycerine 99.7% USP/FCC (all-vegetable) Superol NK      Glycerine 99.7% USP/FCC (non-kosher)  Stark系列共有两个品种：  Star K           Glycerine 96% USP/FCC (Kosher) Star NK          Glycerine 96% USP/FCC (non-kosher)  Moonk系列共有两个品种：  Moon NK          Glycerine 99.7% USP (non-kosher) Moon K           Glycerine 99.7% USP (Kosher) 宝洁公司对Superol K 产品的描述如下：Superol K Glycerine is produced at P&G Chemicals’ Cincinnati plant. It is manufactured entirely from naturally occurring tropical oils (coconut, palm, and palm kernel). 宝洁公司对Moon K产品的描述如下：Moon K Glycerine is produced at P&G Chemicals’ approved and audited facility, but isn’t necessarily owned by P&G.
