Sorbitan sesquioleate

Liquid emulsifier with mild odor.

Sorbitan sesquioleate is a pale-yellow to amber viscous liquid with a slight characteristic odor. It is a non-ionic surfactant that is used in a variety of personal care and cosmetic products, as well as in the food industry. It functions as an emulsifier, solubilizer, and dispersant, and can improve the texture and stability of formulations.

Energy Sector

Sorbitan sesquioleate is used as an emulsifier in the energy sector to improve the stability and effectiveness of oil-based drilling fluids. It helps to create a homogeneous mixture of oil and water, preventing the oil from separating out and facilitating the transport of oil-based fluids in oil and gas drilling operations.

Water Treatment

Sorbitan sesquioleate is not commonly used in water treatment processes. However, it can be used as an emulsifier and dispersant in the production of water treatment chemicals such as coagulants and flocculants. Additionally, it can be used in the formulation of water-based drilling fluids for oil and gas exploration.


Sorbitan sesquioleate is used in agriculture as a wetting agent, emulsifier, and dispersant for agricultural products such as pesticides, herbicides, and fertilizers. It helps to improve the uniformity and effectiveness of the application, reduce the surface tension of the solution, and increase the coverage of the sprayed material. Additionally, it is used in the production of animal feed and as a processing aid for edible oils and fats.
