Composition and Description

PEG-75 LANOLIN is a polyoxyethylene condensate with the best pharmaceutical lanolin. It has a mean chain length of 75 ethylene oxide units and an average molecular weight of about 3.970 Da. The lanolin content in PEG-75 LANOLIN is approximately 17%. It is a hard, pale yellow wax with weak fruity odour.

Features

PEG-75 LANOLIN is ethoxylated, to obtain not only complete water solubility, but also solutions that are crystal clear in all concentrations, both in water and in aqueous ethanol concentrations of up to 40%. The solutions are nonionic and compatible with most other solubilisers including up to 10% electrolytes solutions. The solution is only slightly affected by oxidative and reducing agents. It is stable in a pH range of 2-10. A particularly unique feature of PEG-75 LANOLIN is its carefully controlled manufacturing that ensures minimum viscosity variations of the aqueous solutions.

Applications

PEG-75 LANOLIN is particularly recommended for use in aqueous or aqueous-alcoholic lotions and solutions with high clarity. Moreover, the product has emulsifying, solubilising and emollient properties and a mild cleaning effect. Main applications include skin cleansing and after-shave lotions, as well as in shampoos and detergent formulations, where viscosity is of importance.

Dermatology

PEG-75 LANOLIN is made from pharmaceutical grade lanolin, which complies to the European Pharmacopoeia. It is well established in the market for many years, especially for hair and skin care products. To date, no adverse effects were observed. Patch tests that were made with the 100 % substance in 11 subjects with daily dosing of 2-3 hours over a period of 4 weeks showed no adverse skin reaction.

Processing

When used in solutions, PEG-75 LANOLIN should first be melted, followed by addition of 3 times the amount of hot water under constant stirring. The resulting concentrate is then diluted with either hot or cold water. In order to prepare emulsions, PEG-75 LANOLIN is normally melted together with the oil phase, but it can also be dissolved in the aqueous phase. It should be stored cool in closed containers. Prolonged heating above 80 °C should be avoided.

Solubility at room temperature

Water: soluble; ethanol, anhydrous: soluble; ethanol 80%: partly soluble; ethanol 40%: soluble; mineral oil: slightly soluble
