Composition and Description

LANOLAN EP ELP 3% is produced from multi-stage refining of woolgrease, a natural and renewable raw material, which is obtained from the scouring (washing) of raw wool. It differs from conventional LANOLAN EP ELP by the guaranteed content of free alcohols below 3%. 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 3% meets the requirements of the current European Pharmacopoeia and is characterised by its high purity, light colour, low odour and very low pesticide level. It is purified by molecular distillation that results into less than 3% of free wool wax alcohols. Since it is manufactured gently in modern facilities, the initial peroxide value (measure of oxidation) is very low. Therefore LANOLAN EP ELP 3% 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

Studies have shown that possible allergic effects of lanolin can be almost entirely avoided by a reduction of free lanolin alohols below 3%. Therefore LANOLAN EP ELP 3% is especially suitable for the use in baby creams and lotions, on sensitive or damaged skin and whenever highest purity is required.

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 reduction in the proportion of free lanolin alcohols in LANOLAN EP ELP 3% should result in a significantly lower allergy rate. The oral LD50 is greater than 16 g/kg and no irritating effect on the skin even after regular administration was observed.

Processing

Usage of LANOLAN EP ELP 3% is easy to use and it may be processed 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 3% 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
