Description

Sodium Lauryl Sulfate (SLS) is a fundamental anionic surfactant renowned for its exceptional foaming, emulsifying, and cleansing properties. This high-purity compound is critical for ensuring consistent performance and product stability in demanding formulations. It is an indispensable raw material for manufacturers in the personal care, pharmaceutical, and industrial cleaning sectors seeking reliable quality and supply chain security.

Application

• Personal Care & Cosmetics: Primary foaming and cleansing agent in shampoos, body washes, facial cleansers, toothpaste, and bubble baths.
• Pharmaceuticals: Used as an emulsifying and wetting agent in topical creams, ointments, and medicated shampoos.
• Industrial & Institutional Cleaners: Key surfactant in heavy-duty detergents, car wash soaps, floor cleaners, and degreasers for its powerful grease-cutting action.
• Textile & Leather Processing: Employed as a wetting agent, penetrant, and detergent in scouring, bleaching, and dyeing processes.
• Agrochemical Formulations: Acts as a dispersant and wetting agent in pesticide and herbicide concentrates to improve application efficacy.
• Laboratory & Research: Utilized in biochemical applications such as cell lysis and protein denaturation in electrophoresis (SDS-PAGE).

Quality Control

Our Sodium Lauryl Sulfate is manufactured under a strict quality management system. Each batch is tested against rigorous in-house specifications to ensure consistency in purity, performance, and safety. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, pH, and moisture content. The product can be supplied to meet various grade requirements, including Pharmaceutical (USP/EP) and Kosher standards, subject to customer specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept sealed to prevent caking and degradation due to atmospheric moisture. Keep away from strong oxidizing agents.
