Overview of Span 40 (CAS 26266-57-9) – Nonionic Surfactant Sorbitan Monopalmitate
Nonionic surfactants are a class of surface-active agents that do not carry an electrical charge in aqueous solutions, distinguishing them from ionic surfactants like cationics and anionics. They are composed of a hydrophilic (water-loving) head group and a hydrophobic (oil-loving) tail, which allows them to reduce surface tension between fluids and facilitate interactions between substances that are normally immiscible. Their neutrality makes them stable over a wide pH range and compatible with other types of surfactants, making them highly versatile in numerous applications.
Features of Span 40 (CAS 26266-57-9) – Nonionic Surfactant Sorbitan Monopalmitate
-
Neutral Charge: Lack of charge leads to compatibility with both anionic and cationic substances, reducing the risk of precipitation or instability in formulations.
-
Wide pH Stability: Function effectively across a broad pH range, making them suitable for diverse chemical environments.
-
Solubility: Readily soluble in both water and organic solvents, enhancing their utility in cleaning, emulsification, and dispersion processes.
-
Low Foam Profile: Many nonionic surfactants generate less foam compared to their ionic counterparts, beneficial in applications where excessive foam is undesirable.
-
Wetting and Spreading: Excellent at reducing surface tension, promoting wetting and spreading of liquids on surfaces, improving cleaning and coating processes.
-
Emulsification: Efficiently stabilize oil-in-water or water-in-oil emulsions, depending on their structure, which is crucial in formulations like cosmetics, agrochemicals, and food products.

Specification of Span 40 (CAS 26266-57-9) – Nonionic Surfactant Sorbitan Monopalmitate
Cover 40 is Sorbitan Monopalmitate. Its CAS Computer Registry Number is 26266-57-9. This material is a nonionic surfactant. Nonionic surfactants have no electric fee. They function well in several formulations.
This product looks like a waxy strong. Its shade is normally cream or pale yellow. The material has a moderate particular smell. It feels smooth to the touch.
Chemically, Period 40 is an ester. It creates from palmitic acid and sorbitol. Sorbitol is a sugar alcohol. Palmitic acid is a typical fat. The result is a hydrophobic molecule. Hydrophobic indicates it fends off water.
Solubility is an essential home. Extend 40 liquifies conveniently in numerous organic solvents. Examples include ethanol and mineral oil. It dissolves partly in veggie oils. Solubility in water is really reduced. This low tide solubility defines its usage.
The HLB worth is important. HLB means Hydrophile-Lipophile Equilibrium. Span 40 has an HLB value near 6.7. This number indicates its oil-loving nature. It is suitable for water-in-oil solutions. Water-in-oil ways water droplets are spread in oil.
This surfactant acts largely as an emulsifier. Emulsifiers help blend oil and water. They avoid separation. Extend 40 is good for producing secure w/o solutions. It also works as a spreading representative. Distributing agents assist spread out solids in fluids. It can function as a lube too.
Common applications vary. It prevails in food processing. It assists mix active ingredients like baked goods. The cosmetics sector uses it commonly. It is found in creams and creams. Industrial utilizes consist of lubricating substances and fabrics. Pharmaceuticals use it in some ointments. Agricultural chemicals might include it.
Handling requires standard safety measures. Use ample ventilation. Avoid breathing dirt. Use safety handwear covers and eye defense. Skin call need to be minimized. Clean thoroughly after dealing with. Shop in an amazing, completely dry location. Keep the container firmly secured.
