Superol®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)
Star®系列共有两个品种：
Star K Glycerine 96% USP/FCC (Kosher)
Star NK Glycerine 96% USP/FCC (non-kosher)
Moon®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).
