Description

Sulfuric Acid, Mono-C12-16-Alkyl Esters, Sodium Salts is a high-purity anionic surfactant belonging to the class of sodium alkyl sulfates. This compound is valued for its excellent wetting, emulsifying, and foaming properties in aqueous systems. It is a critical raw material for manufacturers in the personal care, industrial cleaning, and textile processing sectors seeking consistent performance and reliable supply.

Application

• Primary Surfactant in Personal Care: Used in the formulation of shampoos, body washes, liquid soaps, and bubble baths for its rich lather and cleansing efficacy.
• Industrial & Institutional (I&I) Cleaners: Acts as a key foaming and degreasing agent in heavy-duty floor cleaners, vehicle wash solutions, and industrial detergents.
• Textile Processing Auxiliary: Employed as a wetting and scouring agent in textile pretreatment to ensure uniform dye penetration and fabric cleaning.
• Emulsion Polymerization: Serves as an emulsifier in the production of synthetic latexes for paints, coatings, and adhesives.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spray droplet spread and coverage on plant surfaces.
• Metal Working Fluids: Functions as an emulsifier in coolants and drawing compounds to provide lubrication and corrosion inhibition.

Quality Control

Our production of Sodium C12-16 Alkyl Sulfate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance. Quality is verified through parameters including active matter content, unsulfated matter, pH, and color. Certificates of Analysis (COA) documenting these specifications are available for every shipment. We support compliance with relevant frameworks including REACH and guidelines for cosmetics and detergent applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent caking and degradation from atmospheric moisture.
