The properties of lanolin are similar in their indicators toFat, which is produced by the skin of a person. The most valuable property of this substance is expressed by its ability to emulsify up to 140% of glycerin, up to 180-200% of water and up to 40% of ethanol - all from its own mass with the formation of emulsions of the oil / water type.
Even under conditions of a large temperature rangeand humidity lanolin is able to maintain all of its physical parameters-connectivity. Experts have proved that it can hold twice as much water as it weighs itself and yet it does not lose its viscosity. If a small amount of lanolin is added to hydrocarbons and fats, this will dramatically increase their ability to mix with aqueous solutions and water. Moreover, this possibility has caused its wide application in the composition of lipophilic-hydrophilic moieties.
Chemical composition of lanolin
The chemical composition of lanolin is so complex thatIt has not yet been studied and has not been clarified. But for the most part it predstavlyaetsoboy weight combination of higher fatty acids (palmitic, myristic, cerotic et al.)

As raw material is taken woolen fat,Which is extracted from washing water, when primary sheep wool processing is carried out in woolen mills. In the process of washing wool with hot water, an emulsion liquid forms, which contains fats (unsaponified and saponified), wax-like substances (containing lanolin), protein-mucous, coloring and other kinds of unpleasant smelling and contaminants. When there is a centrifugation, a layer emerges, which is then separated, this is called raw lanolin or wool fat. After that, produce lanolin itself, for this you need to perform six operations: wool melting grease, then oxidizing it, then oxidized grease neutralizes, dried, filtered and the finished lanolin is directly fed.

Is in this fat-like mass anda disadvantage which manifests itself in the fact that lanolin is the most allergenic ingredient in the cosmetics, so it can cause a rash on the skin and various redness. However, once a dermatological analysis was performed where the interaction of lanolin with the skin was clarified, 1048 people participated and only 12 people complained an allergic reaction.
Despite this, before you buyand use cosmetics containing this substance, it is necessary to make a small test for a small area of skin, for example, on the skin of the hand, slightly above the wrist, from the inside.
