Steareth-16 is prepared by reacting ethylene oxide with stearyl alcohol where the numerical value in the name corresponds to the average number of units of ethylene oxide.
For example, Steareth-16 is prepared using an average of 16 units of ethylene oxide reacted with stearyl alcohol.
通过使环氧乙烷与硬脂醇反应制备Steareth-16，其中名称中的数值对应于环氧乙烷的平均单元数。
例如，使用平均16个环氧乙烷与硬脂醇反应制得Steareth-16。

The higher ethoxylated derivatives with HLBs above 12 are more water-soluble and noncomedogenic and nonirritating (PEG 75 lanolin).
Two of the lanolin derivatives studied require special comments: (1) The acetylated lanolin alcohols are both comedogenic and irritating, not because of the acetylated lanolin but because of the cetyl acetate additive, and (2) PEG 16 lanolin (Solulan 16) is quite comedogenic and irritating, perhaps secondary to the combination of nonlanolin additives: ceteth-16,oleth-16, and steareth-16.
HLB高於12的較高乙氧基化衍生物(ethoxylated derivatives)具有更高的水溶性和非粉刺性和無刺激性(PEG 75 lanolin)。
研究的兩種羊毛脂衍生物(lanolin derivatives)需要特別說明：(1)乙酰化羊毛脂醇(acetylated lanolin alcohols)既會引起粉刺，又會刺激人，不是因為乙酰化羊毛脂(acetylated lanolin)，而是因為乙酸十六烷基酯添加劑(cetyl acetate additive)，以及(2)PEG 16羊毛脂(PEG 16 lanolin/Solulan) 會引起粉刺和刺激性，可能僅次於非羊毛脂添加劑(nonlanolin additives)的組合：像是ceteth-16，oleth-16和steareth-16。
