Product Description:

Our anionic surfactant product is a high-quality anionic detergent agent that provides superior cleaning performance and excellent surface activity. This product, designed to meet the rigorous demands of the cleaning industry, is characterized by its solubility in water, making it an ideal choice for a variety of applications ranging from household cleaners to industrial degreasers. When dissolved, it forms a clear to pale yellow liquid that is visually unobtrusive and can maintain the aesthetic integrity of the solution it is mixed into.

The surfactant functions as an anionic surface active agent, which means it carries a negative charge when in an aqueous solution. This negative charge allows it to interact effectively with a wide range of dirt and organic matter, encapsulating them in micelles and making them easier to rinse away. Due to this property, it is particularly effective in hard water conditions where calcium and magnesium ions are present. Unlike nonionic or cationic surfactants, our anionic surfactant exhibits excellent performance in such challenging water conditions.

One of the defining physical properties of our anionic surfactant is its surface tension reduction capability, which typically ranges between 30-40 MN/m. This impressive reduction in surface tension is indicative of the product's ability to increase the wetting and spreading properties of liquids, thereby enhancing their cleaning power. This characteristic is particularly beneficial when the surfactant is used as an anionic foaming agent. The product generates a rich and stable foam that increases contact time with surfaces, ensuring thorough cleaning and the removal of soils and residues.

Another advantage of our anionic surfactant is that it has no applicable vapor pressure, which means it does not readily evaporate into the air under normal conditions. This non-volatility ensures that the product remains on the surface for a longer duration, providing a sustained cleaning action without the risk of inhalation hazards associated with volatile organic compounds (VOCs). Similarly, the product's vapor density is also not applicable, as the surfactant is designed to remain in liquid form and not to become airborne, further underscoring its safety profile in various usage environments.

The product's safety and effectiveness make it a versatile component in numerous formulations. It is widely used not only as an anionic detergent agent but also as an emulsifying agent, wetting agent, and dispersing agent. Its compatibility with other surfactants allows it to be an integral part of complex cleaning formulations, where it can complement other ingredients to maximize cleaning efficiency. The surfactant's stability in both acidic and alkaline environments also adds to its versatility, allowing it to be used across a broad pH spectrum.

In summary, our anionic surfactant product stands out in the market due to its excellent solubility in water, clear to pale yellow appearance, high surface activity, and ability to reduce surface tension significantly. With no applicable vapor pressure or vapor density, it is a safe and effective choice for consumers and professionals alike, who require a high-performing anionic surface active agent in their cleaning products. Whether used as an anionic detergent agent, anionic surface active agent, or anionic foaming agent, this product delivers consistent and reliable results across a wide range of cleaning applications.

Anionic surfactants, characterized by their unique chemical formula CnH2n+1OSO3Na, are widely recognized for their superior ability to reduce surface tension, typically ranging from 30-40 MN/m. These surfactants are particularly known for their excellent performance as anionic foaming agents, making them an essential ingredient in a variety of product applications where foam generation is desired. With a density of 1.0-1.2 g/cm³, these surfactants are substantial enough to be effectively dispersed in various formulations without adversely affecting the end product's consistency.

The slight characteristic odor of anionic surfactants is seen as an advantage in many applications, as it does not overpower or interfere with the addition of fragrances or other scent profiles desired in finished products. This makes them highly versatile and suitable for use in personal care and household cleaning products where a neutral base is preferred for the incorporation of additional scents.

Since the boiling point of anionic surfactants is not applicable, they are ideal for use in scenarios that involve high-temperature processing. This stability under heat stress ensures that the surfactant's integrity is maintained throughout the manufacturing process, resulting in a consistent product performance. This property is especially important in industrial applications where the surfactant may be subjected to elevated temperatures during mixing, molding, or curing processes.

As an anionic foaming agent, these surfactants find extensive use in the production of shampoos, body washes, and facial cleansers. The negative ion surfactant component works excellently in capturing dirt and oil, allowing them to be washed away with water, which is why they are also included in dishwashing liquids and laundry detergents. The anionic cleansing agent properties ensure effective soil removal with the added benefit of substantial foam generation, which is often associated with cleaning efficacy by consumers.

Additionally, the anionic nature of these surfactants makes them suitable for applications in industrial cleaners and degreasers. They are also used in textile and fabric softening processes due to their ability to condition fibers and reduce static. In the realm of agriculture, anionic surfactants serve as wetting agents to improve the efficacy of herbicides and insecticides. In every scenario, their function as a negative ion surfactant aids in the dispersion of products, enhancing performance, and user satisfaction.

Overall, the unique attributes of anionic surfactants, such as their specific chemical formula, density, low surface tension, and stability, make them a valuable component across a wide range of applications, solidifying their role as a cornerstone ingredient in the formulation of numerous products within the cleansing and personal care industries, as well as in industrial and agricultural sectors.

Q1: What is an anionic surfactant and how does it work?

A1: An anionic surfactant is a type of surfactant that carries a negative charge on its hydrophilic end. It works by reducing the surface tension between substances, such as between oil and water, making it easier to remove dirt and grime. This is because the negatively charged end is attracted to water, while the hydrophobic tail is attracted to oils and grease, effectively emulsifying and dispersing them in water.

Q2: Can anionic surfactants be used in combination with other types of surfactants?

A2: Yes, anionic surfactants can be used in combination with other types of surfactants, such as nonionic, cationic, or amphoteric surfactants. This is often done to enhance the performance and properties of the product, as different surfactants can provide synergistic effects when used together.

Q3: Are anionic surfactants biodegradable?

A3: Many anionic surfactants are designed to be biodegradable to minimize their environmental impact. However, the rate of biodegradability can vary depending on the specific chemical structure of the surfactant. It is important to refer to the product information or manufacturer's specifications for details on the biodegradability of a particular anionic surfactant.

Q4: What types of products typically contain anionic surfactants?

A4: Anionic surfactants are commonly found in a variety of household and industrial cleaning products, including laundry detergents, dishwashing liquids, shampoos, body washes, and all-purpose cleaners. They are valued for their ability to remove dirt, oils, and stains effectively.

Q5: Are there any precautions to take when handling anionic surfactants?

A5: When handling anionic surfactants, it is important to follow safety guidelines such as wearing appropriate personal protective equipment (PPE) like gloves and goggles. Avoid inhaling fumes and ensure good ventilation in the area. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical advice if necessary. Always read the label and material safety data sheet (MSDS) for specific handling procedures.
