Description

PEG-20 lanolin 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 - Suspending agent. Cosmetic or pharmaceutical suspensions are known to be thermodynamically unstable and it is therefore essential to include in the formulation a suspending agent capable of dispersing any sedimented particulates and reducing the rate of sedimentation. The presence of this agent increases the consistency of the suspension medium and exerts a protective colloidal action with a surfactant action.
