Description

Sodium Cocoyl Isethionate is a high-purity, mild anionic surfactant derived from coconut oil and isethionic acid. This compound is highly valued for its exceptional foaming properties, skin compatibility, and biodegradability, making it a superior alternative to harsher surfactants. It is a critical ingredient for manufacturers in the personal care and detergent industries seeking to formulate premium, gentle cleansing products.

Application

• Personal Care Cleansers: Primary surfactant in syndet (synthetic detergent) bars, facial cleansers, body washes, and baby shampoos for its mildness and rich lather.
• Liquid Soaps & Shower Gels: Used to create stable, pearlescent, and viscosity-building formulations with a luxurious skin feel.
• Sensitive Skin Formulations: Ideal for products targeting eczema-prone or sensitive skin due to its low irritation potential and skin-friendly pH.
• High-End Toiletries: Key component in premium beauty bars, luxury bath products, and dermatologist-recommended cleansers.
• Combination Bars: Blended with traditional soaps to improve mildness, reduce soap scum, and enhance overall user experience.
• Household & I&I Cleaning: Employed in mild industrial and institutional (I&I) detergents where effective yet gentle cleaning is required.

Quality Control

Our Sodium Cocoyl Isethionate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for purity, composition, and performance. A Certificate of Analysis (COA) documenting key parameters such as active matter, free fatty acid, pH, and moisture content is provided with every shipment to guarantee consistency and compliance with your formulation requirements.

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 after opening to prevent caking or degradation due to moisture absorption.
