Lanolin ethoxylated belongs to the class of ethoxylated lanolin derivatives. The purified product is a flaky wax, yellow to amber in colour, and with a faint, characteristic odour.
LANIS ETX 75 consists of polymer chains with a mean length of 75 ethylene oxide units (monomers), which are chemically linked to ester compounds of highest-grade lanolin anhydrous through condensation reaction.
LANIS ETX 75 is water-soluble; often used in clear liquid cosmetics and toiletries, such as cleansing lotions.The resulting macromolecules have a mean molecular weight (MW) of about 4000 Dalton, and consist of a lanolin ester core and a surrounding polyethylene oxide chain.
LANIS ETX 75 is a completely water-soluble derivative of anhydrous lanolin as a result of ethoxylation.
The surrounding polyether chain allows water molecules to assemble a hydrate cage around the unpolar and otherwise virtually insoluble lanolin ester core.
The resulting solutions (both aqueous and ethanolic) are crystal clear at any concentration, non-ionic and compatible with most physiological electrolytes, e.g. sodium chloride. The dissolved lanolin derivatives are chemically rather inert and stable over a wide pH range of 2-10.
LANIS ETX 75 is a multifunctional surfactant with solubilising, emulsifying, wetting and soft detergent-like properties.
It can be used in clear liquid cosmetics and toiletries where viscosity must be controlled, such as in aftershaves and cleansing lotions. It minimises the defatting effect of detergents on skin and hair without impairing their cleansing ability.
Ethoxylated lanolin derivatives are potent solubilisers of insoluble materials such as lanolin, lanolin oil and hydrocarbons. It is also used in stable low-viscosity micro emulsions of insoluble pharmacological compounds for spraying onto wounds or burns.

In addition to its solid anhydrous form, lanolin ethoxylated is also available in a 50% aqueous solution.
The clear, bright yellow viscous liquid has the same characteristics as anhydrous lanolin, with the added advantage of already being dissolved and therefore easier to handle.
