PEG-75 lanolin wax is a chemical compound, polyether lanolin. The term 'eth' refers to the ethoxylation process (reaction with ethylene oxide) after which residues of ethylene oxide and 1,4-dioxane, chemical compounds considered carcinogenic, may remain in the final product. It depends on the degree of purity resulting from the completed reaction. The number after PEG (Polyethylene glycol) indicates the mol of ethylene oxide and the higher this number is, the less it penetrates the skin.

What it is used for and where
Cosmetics
Emulsifying agent. Emulsions are thermodynamically unstable. Emulsifiers have the property to reduce the oil/water or water/oil interfacial tension, improve emulsion stability and also directly influence the stability, sensory properties and surface tension of sunscreens by modulating their filmometric performance.

Surfactant - Solubilising agent. Solubilisation facilitates the diffusion and transport of many cosmetic ingredients, even in the form of microemulsions, on the stratum corneum, improving the effectiveness of formulations.
