PEG-75

Ethoxylated Lanolin

Composition and description

PEG-75 Lanolin is a polyoxyethylene condensate with pharmaceutical lanolin. It has an average 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 a faint fruity odor.

Peculiarities

PEG-75 Lanolin is ethoxylated and allows you to obtain not only complete solubility in water, but also crystal clear solutions in all concentrations both in water and in concentrations of aqueous ethanol up to 40%. The solutions are non-ionic and compatible with most other solubilisates, including up to 10% electrolyte solutions. The solution is weakly affected by oxidizing and reducing agents. It is stable in the pH range 2-10. A particularly unique feature of PEG-75 Lanolin is its carefully controlled production, ensuring minimal variations in the viscosity of aqueous solutions.

Dermatological studies

PEG-75 Lanolin is made from pharmaceutical grade lanolin that complies with the European Pharmacopoeia. It has proven itself well in the market for many years, especially for hair and skin care products. To date, no side effects have been observed.

Features of application

When used in solutions, first melt PEG-75 Lanolin and add 3 portions of hot water with constant stirring. The resulting concentrate is then diluted with hot or cold water. To produce PEG-75 emulsions, Lanolin is usually melted with the oil phase, but it can also be dissolved in the aqueous phase. It should be stored in closed containers. Prolonged heating above 80°C should be avoided.

Solubility at room temperature

• water – soluble;
• anhydrous ethanol – soluble;
• ethanol 80% – partially soluble;
• ethanol 40% – soluble;
• mineral oil – slightly soluble.
