Description

Ammonium Pentadecyl Sulphate is a high-purity anionic surfactant derived from pentadecyl alcohol. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in demanding formulations. It is a critical raw material for manufacturers in the personal care, industrial cleaning, and textile processing sectors seeking reliable performance and consistent quality.

Application

• Primary Surfactant in high-viscosity personal care products like shampoos, body washes, and cream-based cleansers.
• Emulsifying Agent for oil-in-water (O/W) emulsions in cosmetic creams, lotions, and pharmaceutical topical preparations.
• Industrial & Institutional (I&I) Cleaners for hard surface cleaners, degreasers, and vehicle wash formulations requiring strong detergency.
• Textile Processing Aid used in scouring, dyeing, and finishing baths to improve wetting and level dyeing.
• Agricultural Adjuvant in pesticide and herbicide formulations to enhance spray coverage and active ingredient penetration.
• Latex & Polymer Stabilizer in emulsion polymerization processes to control particle size and dispersion stability.

Quality Control

Our Ammonium Pentadecyl Sulphate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, composition, and performance. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
