Product Introduction

Lanolin Alcohol Polyether-n is a non-ionic surfactant derived from lanolin, the natural wax found in sheep's wool, specifically through ethoxylation of lanolin alcohols. It functions primarily as an emulsifier, helping to mix oil and water-based ingredients, as well as an emollient to soften and soothe skin in cosmetic formulations. The 'n' in its name indicates the average number of ethylene oxide units added to the lanolin alcohol during the ethoxylation process, which affects its hydrophilic properties and consequently its behavior in formulations [1]. This material is valued for its ability to stabilize emulsions and contribute to the texture and feel of the final product.

Production Process

The production of Lanolin Alcohol Polyether-n involves several steps starting with the extraction of lanolin from sheep's wool. The lanolin is then processed to isolate the lanolin alcohols, a mixture of sterols and other alcohols. These alcohols are then subjected to ethoxylation, where ethylene oxide is added under controlled conditions. The number of ethylene oxide units added determines the specific properties of the resulting Lanolin Alcohol Polyether-n. The reaction is typically catalyzed by an alkaline catalyst, such as sodium hydroxide [2]. Following ethoxylation, the product is neutralized, purified to remove any residual reactants or by-products, and then standardized to meet specific quality control parameters.

Efficacy and Function

Lanolin Alcohol Polyether-n primarily acts as an emulsifier in cosmetic formulations, enabling the stable mixing of oil and water phases. Its emollient properties contribute to skin softening and moisturization, leaving the skin feeling smooth and supple [3]. It can also function as a stabilizer, preventing the separation of ingredients in a product over time and increasing the shelf life of cosmetic products. Additionally, its presence can enhance the sensory attributes of formulations, providing a desirable texture and feel upon application.

Application Scenarios

Lanolin Alcohol Polyether-n is used across a wide range of cosmetic and personal care products, including creams, lotions, and ointments, where its emulsifying and emollient properties are beneficial. It can be found in hair care products such as conditioners and styling aids, where it contributes to manageability and shine [4]. In skincare, it is often incorporated into moisturizers and cleansers for its ability to improve skin hydration and texture. It is also utilized in sunscreens to help evenly distribute UV filters and provide a smooth application.

Packaging and Transportation

Lanolin Alcohol Polyether-n is typically packaged in plastic drums or containers that are suitable for viscous liquids to prevent leakage and maintain product integrity during transportation. The containers are sealed to prevent contamination and exposure to moisture or air. During transportation, it should be protected from extreme temperatures and direct sunlight to avoid degradation. It is usually transported by road, rail, or sea, in compliance with transportation regulations for non-hazardous materials. Proper labeling with the product name, batch number, and safety information is essential.
