Composition and Description

LANOLAN WAX is a special type of pharmaceutical wool wax, in which the content of natural esters with low emulsifying capacity has been reduced by fractional crystallisation at low temperature without chemical changes. LANOLAN WAX is a complex mixture of esters, di-esters and hydroxy-esters of sterols and aliphatic alcohols with medium- to long-chain fatty acids.

Features

LANOLAN WAX is closely similar to the normal lanolin. However, it forms W/O emulsions with greater stability, particularly at higher temperatures. It is absorbed by the stratum corneum of the skin and has good emollient properties. The appearance of LANOLAN WAX is more opaque than conventional lanolin. The texture is less sticky and firmer. Since it is manufactured gently in modern facilities, the initial peroxide value (measure of oxidation) is very low. Therefore LANOLAN WAX does not need additional stabilisers. Nevertheless, a shelf life of 2 years is guaranteed. Upon request, BHT or natural alpha-tocopherol can be added as stabilisers.

Applications

The use of LANOLAN WAX is particularly suited for W/O emulsified creams and ointments, where high stability is required, especially at tropical temperatures. The resulting emulsions are of pleasant white colour. Hair creams made with LANOLAN WAX give the hair a stronger texture. They are non-ionic and insensitive to water-soluble electrolytes and humectants in a wide range of pH, a prerequisite for highly emollient creams.

Dermatology

LANOLAN WAX is chemically very similar to anhydrous lanolin and complies in all respects with the requirements of many pharmacopoeia with the exception of its melting point. Lanolin has a pronounced emollient effect on the skin. Cracked skin and fissures are flattened and widened due to the natural, moisturizing properties of lanolin. Nearly 40% reduction in skin roughness is achieved in just 1 hour. Lanolin is used in many pharmaceutical and cosmetic products and only very few cases of allergic reactions were observed. The incidence of lanolin allergy in the general population has been estimated to be no more than 5.5 cases per million people. The oral LD50 is greater than 16 g/kg and no irritating effect on the skin even after regular administration was observed.

Processing

LANOLAN WAX is easy to use and it may be processed both cold and melted forms. Heating at temperature close to the melting point for up to four weeks have negligible impact. Longer heating at higher temperatures, particularly above 80 °C should be avoided. To protect against autoxidation LANOLAN WAX should be stored at cool temperatures in closed containers.
