Product Description:

The anionic surfactant product offered is a premium grade anionic surface active agent designed for a variety of industrial and household applications. This efficient anionic wetting agent is characterized by its superior ability to lower the surface tension between various substances, such as liquids and solids or liquids and gases. Engineered with precision, the product boasts a range of features that make it an ideal choice for customers seeking a high-performance surfactant.

One of the key attributes of this anionic surfactant is its appearance, which is a clear to pale yellow liquid. This visual clarity ensures that it can be seamlessly integrated into various formulations without altering the color aesthetics of the end product. The physical state of this anionic surface active agent makes it convenient for handling, storage, and application, providing ease of use for all customers.

In terms of chemical properties, the product has a pH range of 8-10, which indicates that it is mildly basic. This characteristic ensures that the anionic surfactant is gentle on materials and surfaces, reducing the risk of damage or degradation that can occur with more extreme pH levels. This makes the surfactant an excellent choice for applications requiring a delicate touch, such as in the textile or cosmetic industries.

Another crucial property of this anionic surfactant is its density, which falls between 1.0-1.2 g/cm3. This measurement provides an indication of the concentration and quality of the surfactant, assuring users of its substantial active content and effectiveness in various applications. The appropriate density also ensures compatibility with a wide range of formulations, allowing for versatility in its use across different industries.

The refractive index of the anionic surfactant stands between 1.35-1.45, reflecting its purity and consistency. The refractive index is a measure of how much the speed of light is reduced inside the medium, and in the case of surfactants, it can provide insights into the concentration and composition of the solution. A consistent refractive index is a sign of a high-quality product that users can rely on for uniform performance in every batch.

It is important to note that the vapor density of this anionic wetting agent is listed as not applicable. This indicates that under normal conditions, the product is not volatile and does not readily produce vapors that could affect air quality or pose a risk of inhalation. This feature is especially important for ensuring the safety of users and maintaining a healthy working environment, particularly in enclosed spaces.

As a negative ion surfactant, this product carries a charge that allows it to interact effectively with positively charged particles in solutions. This property is central to its function as a surfactant, enabling it to bind with various substances and promote processes such as emulsification, dispersion, and wetting. The anionic nature also means that it is compatible with other negatively charged ingredients, which is useful in complex chemical formulations.

In conclusion, our anionic surfactant product stands out as a versatile and high-quality anionic surface active agent. Its clear to pale yellow appearance, mild pH, appropriate density, and consistent refractive index make it a reliable and effective choice for a wide range of applications. The non-volatile nature of the product further adds to its appeal, ensuring safety and stability for users. Whether employed in industrial processes or household cleaning, this negative ion surfactant is poised to deliver excellent results and enhance the performance of products in which it is used.

Anionic surfactants are versatile chemical agents that possess unique characteristics making them suitable for a wide range of applications. Their ability to lower surface tension, typically within the range of 30-40 MN/m, enables them to function effectively in scenarios that require the breaking down of liquid interfaces. Despite the lack of a defined melting point and their negligible vapor density and pressure, which indicate that they do not easily vaporize, anionic surfactants are highly sought after in various industries.

As an anionic foaming agent, this class of surfactants is commonly used in the manufacture of soaps and detergents. The clear to pale yellow liquid creates a rich lather when mixed with water, which enhances the product's ability to trap dirt and oil particles. This property is particularly beneficial in personal care products such as shampoos and shower gels, as well as in household cleaning products like dishwashing liquids and laundry detergents, where the foam helps to indicate the product's cleaning action.

Moreover, the anionic wetting agent attribute of these surfactants makes them indispensable in the textile industry. During the processing of fibers and fabrics, the application of anionic surfactants ensures uniform wetting, which is crucial for consistent dyeing and finishing. The surfactant's propensity to spread over fibers promotes better penetration of processing chemicals, resulting in improved quality of the finished textile goods.

Anionic solubilizing agents are another key role played by these surfactants. In the pharmaceutical and cosmetic industries, they are used to enhance the solubility of poorly soluble organic compounds. This is particularly important for the formulation of lotions, creams, and transdermal patches where active ingredients need to be effectively delivered through the skin. The clear to pale yellow liquid is adept at incorporating lipophilic substances into aqueous solutions, thus increasing the range of formulations that can be created.

Aside from these traditional roles, anionic surfactants are also used in agricultural products as emulsifiers, in the oil and gas industry for enhanced oil recovery, and in the construction industry to improve the workability of concrete. The versatility and effectiveness of anionic surfactants make them a staple ingredient in products designed for a multitude of occasions and scenarios where reduction of surface tension and enhancement of solubilizing properties are required.
