Overview of Anionic Surfactant

Anionic surfactants are a class of surface-active agents characterized by their negatively charged hydrophilic (water-loving) head groups. These surfactants are widely used in various applications, including detergents, cleaning agents, and personal care products. They excel at removing dirt and oils due to their strong emulsifying and foaming properties. Common types include sodium lauryl sulfate (SLS) and linear alkylbenzene sulfonates (LAS).

Features of Anionic Surfactant

Emulsification: Effective at breaking down oils and fats into smaller droplets, making them easier to wash away.

Foaming Properties: Generate rich, stable foam that enhances cleaning efficiency.

Detergency: Strong ability to lift and remove dirt and grease from surfaces.

Solubility: Highly soluble in water, facilitating easy rinsing and dispersion.

Stability: Stable under a wide range of temperatures and pH levels, ensuring consistent performance.

Compatibility: Often compatible with other surfactants and additives, allowing for versatile formulations.

Cost-Effectiveness: Generally more affordable compared to other types of surfactants, making them popular in mass-market products.

Applications of Research Chemical Powder SLS/Sodium CAS 151-21-3 Sodium Dodecyl Sulfate Anionic Surfactants

Salt Dodecyl Sulfate (SLS), CAS 151-21-3, is a very flexible anionic surfactant extensively identified for its exceptional foaming, emulsifying, and cleaning properties. This research chemical powder plays a crucial duty throughout varied markets as a result of its capability to decrease surface area tension between compounds, making it essential in formulations calling for stability, solubility, or detergency.

In personal treatment and cosmetics, SLS is a key active ingredient in shampoos, body washes, tooth paste, and facial cleansers. It creates abundant lather, efficiently removing dust, oil, and impurities from skin and hair. Its mildness at controlled focus makes certain compatibility with customer items, though solutions usually stabilize its usage with moisturizing agents to minimize possible irritation.

House and commercial cleansing products take advantage of SLS’s grease-cutting power. It is located in washing detergents, meal soaps, and all-purpose cleaners, where it breaks down oils and lifts spots from fabrics and surfaces. Its compatibility with other surfactants improves cleaning up efficiency in tough water conditions.

In scientific research, SLS is a staple in research laboratories. It denatures healthy proteins in techniques like SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis), enabling accurate molecular weight evaluation. It additionally solubilizes membrane layer healthy proteins and lipids in cell biology research studies and help in nucleic acid removal by interfering with cell membrane layers.

The pharmaceutical industry utilizes SLS as an excipient in tablets and creams to enhance drug dissolution and absorption. Its emulsifying properties ensure uniform circulation of energetic ingredients. In industrial applications, SLS acts as a moistening representative in fabric handling, a dispersant in agrochemicals, and a foaming representative in fire resistants.

Researchers value SLS as a version surfactant for studying interfacial phenomena, micelle development, and colloidal systems. While normally safe in controlled dosages, focused SLS powder needs mindful managing to prevent skin or respiratory irritability. Proper storage space in a cool, completely dry setting keeps its stability and efficiency.

With its wide utility extending consumer goods, clinical research, and commercial processes, Sodium Dodecyl Sulfate continues to be a cornerstone chemical, integrating useful convenience with cost-effectiveness. Its versatility continues to drive development in solutions and experimental techniques worldwide.

5 FAQs of Research Chemical Powder SLS/Sodium CAS 151-21-3 Sodium Dodecyl Sulfate Anionic Surfactants

**What is Sodium Dodecyl Sulfate (SLS) CAS 151-21-3?**
Sodium Dodecyl Sulfate (SLS), with CAS number 151-21-3, is an anionic surfactant widely used in industrial, cosmetic, and research applications. It is a white crystalline powder that reduces surface tension in liquids, acting as a detergent, emulsifier, or foaming agent. Its molecular structure includes a hydrophilic sulfate group and a hydrophobic 12-carbon chain, enabling it to interact with both water and oils.

**What are the primary applications of SLS?**
SLS is commonly found in household cleaners, personal care products (shampoos, toothpaste), and laboratory settings. In research, it is used to solubilize proteins during electrophoresis, disrupt cell membranes, or stabilize emulsions. Its strong degreasing and foaming properties make it ideal for industrial formulations like detergents, fire retardants, and textile processing agents.

**Is SLS safe for use in cosmetics and personal care?**
SLS is generally safe in diluted concentrations (1–10%) for rinse-off products like shampoos. However, prolonged exposure to high concentrations may cause skin or eye irritation. Regulatory bodies like the FDA and EFSA approve its use in cosmetics when formulated appropriately. Always follow safety guidelines and avoid direct contact with undiluted powder.

**How should SLS be stored and handled?**
Store SLS in a cool, dry place away from moisture, heat, and direct sunlight. Use airtight containers to prevent clumping. When handling, wear PPE (gloves, goggles, mask) to avoid inhalation or skin contact. In case of accidental exposure, rinse thoroughly with water. Shelf life is typically 2–3 years if stored correctly.

**How does SLS differ from other surfactants like SLES?**
SLS (sodium dodecyl sulfate) and SLES (sodium laureth sulfate) are both anionic surfactants, but SLES has an ethoxylated chain, making it milder and less irritating. SLS is a stronger degreaser, while SLES is preferred in products requiring gentler foaming. SLS is also cheaper and more widely used in research due to its predictable behavior in biochemical processes.
