Peg-5 lanolin

PEG-5 Lanolin (CAS 61790-81-6), also marketed as PEG-75 Lanolin and known commercially as ethoxylated lanolin, is produced by reacting natural wool wax with ethylene oxide to yield a water-soluble lanolin derivative. It functions primarily as an emulsifier, humectant, and wetting agent across personal care, textile, and industrial formulations. In cosmetic formulations, it stabilizes oil-in-water emulsions in creams and lotions.

It is also used in hair conditioners while improving moisture retention on skin and hair. Textile processors use it as a fiber lubricant and softening agent in spinning baths and finishing treatments. In these industrial settings, it reduces static and improves handle. Leather manufacturers incorporate it into fat-liquoring compounds to condition hides during processing to ensure a high-quality finish.

In pharmaceutical topical preparations, it acts as an emulsifying excipient that enhances spreadability and compatibility with active ingredients. This makes it a versatile component for various medical creams. PEG-5 Lanolin is typically supplied as a viscous liquid or soft paste, depending on the degree of ethoxylation. Cosmetic-grade and pharmaceutical-grade specifications are the most commonly available.

The pharmaceutical material meets USP or Ph. Eur. standards where applicable. Industrial-grade material is also offered for textile and leather processing applications to meet specific manufacturing needs.
