Sorbitan monooleate CAS 1338-43-8

Sorbitol monoleate, also known as sorbitol anhydride monoleate, can be used as a non-ionic surfactant.

About Sorbitan monooleate:

First, sorbitan oleate is a non-ionic surfactant with hydrophilic and lipophilic properties. Its molecular structure is composed of two parts: sorbitol and oleate. Sorbitol is an organic alcohol with multiple hydroxyl groups, which make the molecule hydrophilic. The oleate part is hydrophobic and can be combined with oil substances. This special molecular structure enables sorbitan oleate to attract water and oil molecules in aqueous solution, reduce surface tension, and play a good role in emulsification, dispersion, wetting, etc.

Secondly, sorbitan oleate has good stability. It can maintain good stability in weakly acidic and weakly alkaline media and is not easy to hydrolyze or oxidize. In addition, sorbitan oleate has a certain heat resistance and is not easy to decompose or lose activity at high temperatures. This allows it to perform well over various temperatures and pH.

Thirdly, sorbitan oleate has excellent wettability and permeability. It can effectively reduce the interfacial tension of oil and water, make oily substances better dispersed in water, and improve the wettability and permeability of the system. This makes sorbitan oleate widely used in cosmetics, textiles, printing and dyeing, metal processing, and other fields as an emulsifier, wetting agent, softener, and other additives.

In addition, sorbitan oleate also has certain antibacterial properties. In the fields of cosmetics, paint and coatings, sorbitan oleate can be used as a preservative or antibacterial agent to improve product health and safety performance.

Applications of  Sorbitan monooleate  :

Cosmetics industry: In cosmetics, sorbitan oleate is mainly used as an emulsifier, wetting agent and thickener. It can reduce the interfacial tension of oil and water, improve the wettability and permeability of products, and make cosmetics more easily absorbed by the skin. At the same time, sorbitan oleate also has certain antibacterial properties, which help maintain the hygiene and safety of cosmetics. In face cream, lotion, shampoo, body wash, and other cosmetics, sorbitan oleate is widely used as the main or auxiliary ingredient.

Textile and printing industry: In the textile and printing industry, sorbitan oleate is mainly used as a softener, antistatic agent, and penetrant. It can improve the fabric's feel, gloss, and antistatic properties, the printing and dyeing effect, and the quality of the fabric. At the same time, sorbitan oleate can also be used as dyeing AIDS, fixing agents, etc., to improve dyes' coloring effect and durability.

Paints and coatings industry: Sorbitan oleate is mainly used as a wetting agent, leveling agent and dispersant. It can improve the fluidity and leveling of the paint, improve the coverage and uniformity of the paint, and make the coating smoother, more uniform, and more beautiful. At the same time, sorbitan oleate can also inhibit the settlement of pigments and fillers and extend the service life of coatings.

Pharmaceutical industry: In producing drugs, sorbitan oleate can be used as a drug carrier, emulsifier, etc. It can effectively disperse drug components uniformly in the medium and improve the stability and bioavailability of the drug. At the same time, sorbitan oleate has lower toxicity and better biocompatibility and is also used in some medical devices and pharmaceutical excipients.

Agricultural field: In pesticides and fertilizers, sorbitan oleate is mainly used as an emulsifier, wetting agent and thickening agent. It can improve the wettability and adhesion of pesticides, making it easier for pesticides to adhere to plant surfaces and play a role. At the same time, sorbitan oleate can also improve fertilizer's solubility and permeability, improving fertilizer's utilization rate and absorption effect.

Production Method of  Sorbitan monooleate  :

Raw material preparation

The main raw materials for producing lost sorbitan oleate include sorbitan, oleic acid, a catalyst, and the appropriate amount of water. Among them, sorbitol is the starting material and provides the hydrophilic part; oleic acid provides the hydrophobic part; the catalyst is used to accelerate the reaction process; and water plays a role in regulating the balance of the reaction.

Synthesis steps

Esterification reaction: The sorbitol and oleic acid are esterified under the catalyst to produce the dehydrated sorbitol oleate and by-product water. This step is the key to the entire production process, and it is necessary to control the conditions of the esterification reaction, such as temperature, pressure, reaction time, etc., to ensure the complete esterification reaction and the stability of the product.

Dehydration treatment: The product obtained by esterification may contain unreacted sorbitol and water. Therefore, a dewatering treatment is required to remove excess water and unreacted sorbitol. This step usually uses heating, vacuum, or centrifugation to separate the water and the unreacted sorbitol from the product.

Refining and purification: The products obtained after dehydration may also contain some by-products and impurities. Therefore, refining and purification steps are required to improve the purity and stability of the product. This step typically removes impurities and by-products by filtration, recrystallization, or extraction.

Drying and packaging: The resulting dehydrated sorbitan oleate is dried and packaged for subsequent application. When drying, attention should be paid to controlling temperature and humidity to avoid degradation or caking of sorbitan oleate. At the same time, it is also necessary to choose the appropriate drying method and equipment according to the actual situation to improve product quality and production efficiency.
