Exploring the Properties and Applications of Chemical Compound with CAS Number 26172-55-4 in Industry

Understanding the Significance of CAS Number 26172-55-4

In the realm of chemistry and biochemistry, the Chemical Abstracts Service (CAS) plays a crucial role in the identification and classification of chemical substances. One of the key components of this system is the CAS number, a unique numerical identifier assigned to every chemical compound. In this article, we will delve into the details surrounding CAS number 26172-55-4, exploring its significance, classification, applications, and safety considerations.

What is CAS Number 26172-55-4?

CAS number 26172-55-4 corresponds to a chemical known as Sodium Lauryl Sulfate (SLS), a widely used anionic surfactant. Characterized by its long hydrophobic chain, it is commonly derived from natural sources such as coconut oil or palm kernel oil. Its structural formula consists of a sulfate group bonded to a lauryl alkyl chain, which is 12 carbons long, making it effective in reducing surface tension in liquids.

Classification and Properties

Sodium Lauryl Sulfate is classified as a surfactant, meaning it can solubilize oil and dirt in water, allowing for easy rinsing and cleaning. This compound is soluble in water and exhibits excellent wetting properties. SLS is characterized by its foaming ability, which is why it is favored in many personal care products, detergents, and industrial applications. Additionally, it has emulsifying properties, enabling the mixing of oil and water.

The chemical formula of SLS is C12H25NaO4S, and its molecular weight is 288.38 g/mol. When encountered in its pure form, it appears as a white or cream-colored powder or flaky solid. Its effective pH range is generally between 6 and 8, allowing it to maintain stability in many formulations.

Applications of Sodium Lauryl Sulfate

Sodium Lauryl Sulfate is ubiquitous in the formulation of various products, especially those in the personal care and cosmetics industries. It is primarily found in shampoos, toothpastes, body washes, and bubble baths due to its ability to create lather and enhance cleaning efficacy.

Beyond personal care, SLS is utilized in industrial formulations as well. It serves in the manufacturing of latex products, textile processing, and as a wetting agent in various cleaning applications. The pharmaceutical industry also employs SLS as an excipient in drug formulations, where it helps improve the solubility of active ingredients.

Safety and Environmental Considerations

Although Sodium Lauryl Sulfate is generally regarded as safe for use in consumer products, it is essential to recognize its potential irritancy. The compound can cause skin irritation in sensitive individuals, especially when used in high concentrations. Consequently, many formulations include SLS at lower concentrations or use alternative surfactants to reduce the risk of irritation.

From an environmental perspective, SLS is biodegradable, which means it breaks down naturally over time. However, the production of SLS, like many surfactants, can have ecological implications if not managed properly. Responsible sourcing of raw materials – preferably from renewable sources – remains a critical aspect of its use.

Conclusion

CAS number 26172-55-4 (Sodium Lauryl Sulfate) is a compound that epitomizes the dual role of surfactants in modern applications. Its effectiveness as a cleaning agent, foaming agent, and emulsifier has solidified its place in both personal care and industrial products. However, it is imperative for consumers and manufacturers alike to stay informed about the safety and environmental impacts associated with its use. By understanding the properties and applications of SLS, we can make more informed choices about the products we use and their impact on health and the environment.
