Nonadecan-9-ol is primarily used in the formulation of surfactants and emulsifiers due to its long hydrocarbon chain and hydroxyl group, which make it effective in reducing surface tension. It is often incorporated into industrial cleaning agents and detergents to enhance their ability to dissolve oils and greases. Additionally, it finds application in the production of lubricants and coatings, where it helps improve smoothness and durability. In the cosmetic industry, it is utilized as a thickening agent and emollient in skincare products, contributing to a softer texture and better moisture retention. Its chemical properties also make it suitable for use in research and development of organic compounds and polymers.
