Overview of Alcohol Polyoxyethylene Ether Emulsifier Detergent AEO-7 Nonionic Surfactants CAS 68131-39-5
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 Alcohol Polyoxyethylene Ether Emulsifier Detergent AEO-7 Nonionic Surfactants CAS 68131-39-5
-
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.

Parameter of Alcohol Polyoxyethylene Ether Emulsifier Detergent AEO-7 Nonionic Surfactants CAS 68131-39-5
The concentration of alcohol poloyoxyethylene ether emulsifier (AEO-7) in the detergent is 7%. The chemical formula for this nonionic surfactant is (C4H9O2)2, and its molecular weight is approximately 804.6 g/mol. The molecular weight of the corresponding salt (C4H9SO4) is approximately 236.8 g/mol. The parameter for this surfactant is the pseudo-critical micelle concentration (PMC), which is calculated as the molar concentration at which the surface tension of a droplet becomes equal to that of a bulk liquid.
The molecular weight of C4H9O2 (AEO-7) is much less than that of the corresponding salt (C4H9SO4), so it will not form a micelle on water surfaces. This means that it will be more effective at reducing dirt and grease stains on clothing and other surfaces.
The PEC value for AEO-7 can be calculated using the following equation:
PMC = [M] / [(M1 + M2) / 2]
where [M] is the molecular weight of the substance being analyzed, and [M1], [M2] are the molecular weights of the two substances being compared.
The exact values for these parameters may vary depending on the specific application and formulation requirements of the detergent. However, it is generally accepted that nonionic surfactants with lower PECs are more effective at cleaning surfaces and removing dirt and grease.

FAQs of Alcohol Polyoxyethylene Ether Emulsifier Detergent AEO-7 Nonionic Surfactants CAS 68131-39-5
Q: Is Alcohol Polyoxyethylene Ether Emulsifier Detergent AEO-7 Nonionic Surfactants CAS 68131-39-5 biodegradable?
A: Biodegradability varies; many nonionic surfactants are designed to be biodegradable to minimize environmental impact, but it’s important to check specific product labels.
Q: Why is Alcohol Polyoxyethylene Ether Emulsifier Detergent AEO-7 Nonionic Surfactants CAS 68131-39-5 used in low-foaming applications?
A: Their molecular structure tends to produce less foam than ionic surfactants, making them suitable for applications where foam could interfere with processes or cleaning effectiveness.
Q: Can Alcohol Polyoxyethylene Ether Emulsifier Detergent AEO-7 Nonionic Surfactants CAS 68131-39-5 be used in hard water conditions?
A: Yes, their performance is generally not affected by the presence of minerals in hard water, unlike some ionic surfactants that can precipitate.
Q: How do Alcohol Polyoxyethylene Ether Emulsifier Detergent AEO-7 Nonionic Surfactants CAS 68131-39-5 affect the skin?
A: Generally, they are considered mild and less irritating than ionic surfactants, making them popular in personal care products.
Q: Are all nonionic surfactants soluble in cold water?
A: Not necessarily. While many nonionic surfactants are cold-water soluble, some may require warmer temperatures to fully dissolve or exhibit optimal performance.
