Product Details

Zhejiang Camp-Shinning is providing this article of product details of Sorbitan Oleate, for further analysis of the chemical. We listed important information you may need to know about  Sorbitan Oleate 80.

Chemical Description

Sorbitan Monooleate is a non-ionic surfactant that possesses several distinctive chemical characteristics. It is primarily utilized in the formation of oil-in-water emulsions, where it effectively stabilizes the interface between oil and water.

Furthermore, when combined with low hydrophilic-lipophilic balance (HLB) surfactants, Sorbitan Monooleate can facilitate the creation of water-in-oil emulsions.

It is an EPA-approved oil spill dispersant, an essential component in environmental cleanup efforts. The hydrophobic nature enables it to interact strongly with oil molecules, and it is promoting their dispersion and aiding in the breakdown of oil spills.

Chemically, Sorbitan Oleate belongs to the sorbitan ester series of surfactants. It is produced through the esterification process, which involves the reaction of one or more hydroxyl groups of sorbitan with fatty acids.

This reaction leads to the formation of a sorbitan ester, specifically sorbitan monooleate, which is the primary composition of Sorbitan Oleate.

Chemical Name

Sorbitan Oleate chemical name is sorbitan monooleate. This name accurately describes the molecular composition of the compound. Sorbitan refers to the core structure derived from sorbitol, a sugar alcohol.

Monooleate indicates that the compound is formed through the esterification of one molecule of sorbitan with oleic acid, a fatty acid. This chemical name specifies the specific fatty acid involved in the esterification process, highlighting the presence of the oleate group.

Molecular Weight

Sorbitan Oleate molecular weight is determined by adding the atomic weights of the carbon, hydrogen, and oxygen atoms present in its chemical formula. The molecular weight of 428.60 g/mol provides valuable information about the mass of Sorbitan Oleate 80 on a molecular scale.

Ingredient Origin

Oleic acid, a fatty acid commonly found in vegetable oils such as olive oil, provides the hydrophobic properties necessary for Sorbitan Oleate‘s emulsifying capabilities. Sorbitol, a sugar alcohol derived from the hydrogenation of glucose, serves as the backbone for the sorbitan structure in Sorbitan Oleate 80.

This combination of oleic acid and sorbitol results in a surfactant with excellent emulsifying properties, making S 80 a preferred choice in various industries.

Functions

As S 80 emulsifier, it plays a crucial role in forming and stabilizing emulsions. It enables the dispersion of oil droplets in water, creating oil-in-water emulsions. It also acts as a wetting agent, improving the spreadability and contact of liquids on solid surfaces.

It reduces the surface tension of liquids, allowing them to penetrate and cover surfaces more effectively. It can also function as an antifoam and defoamer agent.

Physical Form

The color of Sorbitan Oleate S 80 can range from pale yellow to a deeper amber hue, depending on factors such as purity and storage conditions.

Density of Sorbitan Oleate s 80 can vary slightly from 0.97 to 1.03 g/cm3, which is a moderately high density. Span 80 viscosity is heavier compared to an equal volume of water.

HLB

The Hydrophilic-Lipophilic Balance value of Sorbitan Oleate is 4.3. The HLB value is a measure of the relative hydrophilic and lipophilic properties of a surfactant. Sorbitan Oleate80  HLB value of 4.3 places it within the typical range for water-in-oil emulsifiers.

Sorbitan Oleate has a slightly higher affinity for oil than water. It is commonly used in formulations where the goal is to create stable water-in-oil emulsions.

A lower HLB value indicates a higher affinity towards lipophilic substances. In comparison between S  20 vs S 80, S 80 has lower HLB value indicates a stronger preference for oil and hydrophobic environments.

S 80 particularly suitable for applications where oil-in-water emulsions are desired, as it can efficiently stabilize and disperse oil droplets in water-based systems. Sorbitan Oleate S 20 with a higher HLB value exhibits more hydrophilic characteristics, making it better suited for water-in-oil emulsions.

Applications

Its primary applications is as an emulsifier, facilitating the formation and stabilization of emulsions, particularly oil-in-water emulsions. By reducing the interfacial tension between oil and water, Sorbitan Oleate S 80 enables the homogeneous dispersion of oil droplets within water-based systems.

It also serves as an emulsion stabilizer, helping to maintain the stability and uniformity of emulsions over time. Its presence prevents phase separation and enhances the shelf life of emulsion-based products.

Another important application of Sorbitan Oleate S 80 is as a pigment wetter. In the paint, ink, and coatings industries, it aids in dispersing and wetting pigments, ensuring their even distribution and adherence to surfaces.

It also acts as a surfactant and dispersing agent, enhancing the Sorbitan Oleate S 80 solubility and dispersibility of various substances in liquid systems. It enables efficient mixing, reduces surface tension, and promotes the uniform dispersion of particles or ingredients.

As with any chemical substance, it is crucial to consult the safety data sheet (Sorbitan Oleate 80 SDS) provided by Zhejiang Camp-Shinning for specific information regarding handling, storage, and safety precautions.

Sorbitan Oleate 80 Preparation Products and Raw Materials

First, a sorbitol solution is heated to remove excess water, resulting in sorbitol. Then, sorbitol reacts with a catalyst to produce sorbitan. Next, oleic acid is refined to obtain essential oil.

The oleic acid and sorbitan anhydride are mixed and subjected to an esterification reaction in a reaction kettle for about 3 hours at a temperature of 210-220°C. The resulting mixture is then dehydrated and subjected to further esterification under vacuum to obtain a crude product.

The crude product is cooled and precipitated, and the sediment is removed, leaving behind the final product, which is the emulsifier Sorbitan Oleate S 80.

The advantage of this process is that by adjusting the molar ratio of acid to alcohol, it is possible to reduce the amount of raw materials needed, decrease the residue of sorbitol, increase the amount of product produced, and improve the production rate of the emulsifier Sorbitan Oleate S 80.
