Composition and Description

LANOLAN EP ELP is produced from the multi-stage refining of wool grease, a natural, renewable raw material, which is obtained from the scouring (washing) of raw wool. It is yellowish with a waxy consistency and melts at temperatures above 40 °C. Lanolin 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 EP ELP meets the requirements of the current European Pharmacopoeia and is characterised by its high purity, light colour, low odour and very low pesticide level. Since it is manufactured gently in modern facilities, the initial peroxide value (measure of oxidation) is very low. Therefore LANOLAN EP ELP 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 product can be used in applications where colour, odour and purity are critical. LANOLAN EP ELP has been refined to a point where trace pesticide residues are undetectable. The high purity without sacrificing product colour makes it ideal for use in topical pharmaceutical preparations, suppositories, lip products and baby creams or lotions.

Dermatology

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 EP ELP is easy to use and it may be processed in both cold and melted forms. It is non-hazardous and melts easily with a relatively low volatility. Prolonged heating above the melting point should be avoided. However, heat sterilisation is possible. LANOLAN EP ELP should be stored cool, protected from light in containers and surface exposure to air should be kept at minimum.

Solubility at room temperature

Water: none; mineral oil: partially soluble; castor oil: soluble; oleyl alcohols: soluble; isopropyl myristate: partially soluble
