Description

Sodium Cocoyl Isethionate is a high-purity, mild anionic surfactant derived from coconut oil. This compound is highly valued for its excellent foaming properties, skin compatibility, and biodegradability, making it a premium ingredient for demanding formulations. It is primarily used by manufacturers in the personal care, cosmetics, and detergent industries seeking superior mildness and performance.

Application

• Premium Personal Cleansers: A key surfactant in syndet (synthetic detergent) bars, liquid facial cleansers, and body washes where mildness is critical.
• Baby Care Products: Formulated into gentle baby shampoos, soaps, and bath products due to its low irritation potential.
• Sensitive Skin Formulations: Used in products designed for sensitive, eczema-prone, or dermatologist-recommended skincare lines.
• High-End Cosmetics: Incorporated into creamy makeup removers, cleansing milks, and foaming mousses for a luxurious feel.
• Oral Care: Employed as a foaming agent in mild toothpastes and mouthwashes.
• Household Detergents: Used in premium hand dishwashing liquids and fine fabric washes for its gentle yet effective cleaning.

Quality Control

Our Sodium Cocoyl Isethionate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for purity, active matter, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and fatty alcohol content 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, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent caking or degradation due to moisture absorption.
