Many people say they don't know what lanolin does. Today, Henan Jingke Pharmaceutical Co., Ltd. will give you a popular science. Lanolin is a kind of secretory oil attached to wool. Its main components are esters generated by sterols, fatty alcohols and triterpenols and about the same amount of fatty acids, accounting for about 95%, and it also contains 4% free alcohols, with a small amount of free fatty acids and hydrocarbons. White or light yellow to dark brown paste translucent body, with odor, and the relative density of anhydrous matter is 0.946. Softening point 38 ~ 44 ℃. acid value

羊毛脂精制品有两种，即无水羊毛脂和有水羊毛脂。无水羊毛脂为淡黄色或棕黄色的软膏状物；有黏性而滑腻；臭微弱而特异。在氯仿或乙醚中易溶，在热乙醇中溶解，在乙醇中极微溶解，在水中不溶，但能与约2倍量的水均匀混合，并且有优良的乳化性能。羊毛脂在苛性碱中不被皂化，但在苛性碱的乙醇溶液中，加压、加热，则可被皂化。吸湿性强。Mp36-42℃，酸值不大于1.5，皂化值为92-106(测定时加热回流时间为2h)，碘值为18-35(测定时在暗处放置时间为4h)。含水羊毛脂为羊毛脂熔化后加蒸馏水混合而得，为淡黄色或类白色软膏状物，含水25%-35%。溶于乙醚、氯仿；不溶于水。羊毛脂化学性质稳定，对金属表面有良好的粘接力。

There are two kinds of lanolin refined products, namely anhydrous lanolin and lanolin with water. Anhydrous lanolin is light yellow or brownish yellow ointment; Sticky and greasy; The odor is weak and specific. It is soluble in chloroform or ether, soluble in hot ethanol, very slightly soluble in ethanol, insoluble in water, but it can be evenly mixed with about twice the amount of water, and has excellent emulsifying performance. Lanolin is not saponified in caustic soda, but it can be saponified in ethanol solution of caustic soda under pressure and heating. Strong moisture absorption. Mp36-42 ℃, acid value is not greater than 1.5, saponification value is 92-106 (heating reflux time is 2H during determination), iodine value is 18-35 (placing time in the dark is 4H during determination). Aqueous Lanolin is obtained by melting lanolin and adding distilled water. It is a light yellow or quasi white ointment with water content of 25% - 35%. Soluble in ether and chloroform; Insoluble in water. Lanolin has stable chemical properties and good adhesion to metal surfaces.

能使主药迅速被粘膜及皮肤吸收，有附着力，性质稳定，且能吸水，不易酸败。为优良的软膏基质及油包水型乳剂的乳化剂，用量为5%。因粘稠性大，涂于局部有不适感，故不宜单独用作基质，常与凡士林合用，并可增加凡士林的吸水性与穿透性。

It can make the main drug quickly absorbed by the mucosa and skin, has adhesion, has stable properties, can absorb water, and is not easy to rancidity. It is an excellent ointment matrix and emulsifier of water in oil emulsion. The dosage is 5%. Due to its high viscosity, it is uncomfortable to apply it locally, so it should not be used as a substrate alone. It is often used with Vaseline, and can increase the water absorption and penetration of Vaseline.
