説明
A purified, yellowish white, semisolid, fatlike substance extracted

about twice its weight of water without separation. It is soluble in
chloroform and in ether.
化学的特性
Hydrous lanolin is a pale yellow-colored, unctuous substance with a
faint characteristic odor. When melted by heating on a water bath,
hydrous lanolin separates into a clear oily layer and a clear water
layer.
使用
lanolin USP (modified) is an emollient and an emulsifier. This is a highly purified lanolin that meets uSP monograph specifications requiring analysis for trace contaminants.
調製方法
Lanolin is melted, and sufficient purified water is gradually added
with constant stirring.

and cosmetics in applications similar to those for lanolin.

hydrous lanolin than into lanolin.

pharmaceutical formulations and is generally regarded as a
nontoxic and nonirritant material, although it has been associated
with hypersensitivity reactions. See Lanolin for further information.
