INCI Name: Lanolin PEG 75 / Ethoxylated Lanolin or Lanolin Alcohol Ethoxylate

Chemical Structure and Formula

Ethoxylated lanolin is a diverse composition obtained from lanolin (wool wax), which mainly contains fatty alcohols and esters. The extent of ethoxylation can differ, leading to a range of molecular weights and structures.

Ethoxylated lanolin can play a role in disinfectant formulations due to its properties as an emulsifier and skin conditioner. Here are some specific applications:

Emulsification: It helps stabilize emulsions in disinfectants, allowing for the even distribution of active ingredients, which can enhance the effectiveness of the disinfectant.

Skin Conditioning: In disinfectants intended for skin use (like hand sanitizers), ethoxylated lanolin can provide moisturizing benefits, reducing skin irritation that might be caused by other harsher disinfectant ingredients.

Thickening Agent: It can contribute to the viscosity of liquid disinfectants, helping to improve application and adherence to surfaces.

Compatibility with Other Ingredients: Ethoxylated lanolin can improve the compatibility of various components in disinfectants, ensuring a more uniform product.

Surfactant Properties: It can aid in breaking down organic materials, enhancing the cleaning properties of disinfectants.

Overall, while ethoxylated lanolin is not a primary active ingredient in disinfectants, its functional properties can enhance the overall performance and user experience of the product.

Lanolin, a natural wax obtained from sheep’s wool, serves as a versatile raw material in various industries, particularly in cosmetics and pharmaceuticals. The ethoxylation process of lanolin involves the addition of ethylene oxide (EO) to enhance its properties and extend its applications.

Initial Structure of Lanolin

Lanolin, in its natural state, is a complex mixture of esters, alcohols, and lanolin acids. Its molecular structure forms the basis for the ethoxylation process.

Introduction of Ethylene Oxide (EO)

Ethylene oxide, a reactive and versatile epoxide, is introduced to lanolin in the presence of a catalyst. This catalyst, often an alkaline substance, facilitates the ethoxylation reaction.

Chemical Reaction

During ethoxylation, ethylene oxide reacts with lanolin, leading to the formation of ethoxylated lanolin. This process involves the addition of multiple ethylene oxide units to the lanolin structure, resulting in a product with altered chemical and physical properties.

Catalyst and Reaction Conditions

The ethoxylation reaction is typically carried out under controlled conditions, including specific temperatures and pressures. The catalyst assists in promoting the reaction efficiency and influencing the final characteristics of the ethoxylated lanolin.

Enhanced Properties

Ethoxylation imparts desirable properties to lanolin, such as improved solubility, emulsifying capabilities, and reduced viscosity. These modifications enhance the versatility of ethoxylated lanolin in various industrial applications.

Applications of Ethoxylated Lanolin

The ethoxylation process transforms lanolin into a more adaptable and multifunctional ingredient. Ethoxylated lanolin finds applications in cosmetics, skincare products, pharmaceuticals, and industrial formulations, where its modified properties contribute to product performance and stability.

In summary, the ethoxylation of lanolin is a controlled chemical process that transforms the natural wax into a more versatile and valuable compound. By carefully manipulating the molecular structure through ethoxylation, lanolin becomes a key ingredient in a wide range of products, offering enhanced functionality and performance.
