Overview of Non-ionic oil-in-water emulsifier Steareth-21 9005-00-9 nonionic Steareth-21
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 Non-ionic oil-in-water emulsifier Steareth-21 9005-00-9 nonionic Steareth-21
-
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 Non-ionic oil-in-water emulsifier Steareth-21 9005-00-9 nonionic Steareth-21
The nonionic soap Emulsion Steareth-21 is made by mixing detergents such as sodium lauryl sulfate (SLS) and fatty acids like stearic acid (C17H35COO). The formula for the emulsion would be:
Emulsion = Sodium Lauryl Sulfate + C17H35COO + Water
To determine the specific parameters of this emulsion, such as its viscosity and solubility in water, you will need to perform experiments using physical and chemical techniques. In general, the nonionic nature of Steareth-21 makes it useful for emulsifying and suspensions. It also has a high melting point and boiling point, which can affect its stability and texture.
The nonionic parameter, typically represented as Kd, is used to describe the stability of an emulsion. It represents the ratio of droplet size to liquid saturation level at the given temperature and concentration. A lower Kd value indicates higher stability, while a higher Kd value indicates lower stability. The value of Kd depends on various factors such as the type of detergent used, the presence of other additives, and the temperature and pressure conditions.

FAQs of Non-ionic oil-in-water emulsifier Steareth-21 9005-00-9 nonionic Steareth-21
Q: Is Non-ionic oil-in-water emulsifier Steareth-21 9005-00-9 nonionic Steareth-21 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 Non-ionic oil-in-water emulsifier Steareth-21 9005-00-9 nonionic Steareth-21 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 Non-ionic oil-in-water emulsifier Steareth-21 9005-00-9 nonionic Steareth-21 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 Non-ionic oil-in-water emulsifier Steareth-21 9005-00-9 nonionic Steareth-21 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.
