1. Basic Information

• Chinese Name: 月桂酰羟乙基磺酸钠 (Sodium Lauroyl Isethionate)
• English Name: Sodium Lauroyl Isethionate
• Synonyms: Sodium 2-sulfoethyl laurate; Igepon A; Sodium lauroyl oxyethyl sulfonate
• Molecular Formula: C14​H29​NaO5​S
• Molecular Weight: 332.43
• EINECS Number: 230-949-8

2. Physical and Chemical Properties

• Appearance: White acicular granules or white flaky solids, with a slight odor.
• Active Matter Content: 78% – 83%
• Solubility: Extremely low water solubility in cold water, suitable for formulating cream-like products with short rheological properties (low flowability).

3. Performance Characteristics

• Ultra-Mild and Non-Irritating: No irritation to skin or mucous membranes, with extremely gentle properties, making it ideal for sensitive skin and baby care products.
• Rich Foaming: Produces rich, fine foam similar to soap-based products. The foam is bright, can accumulate, and maintains stability without fading easily.
• Strong Hard Water Resistance: Its foaming performance is hardly affected by water hardness (calcium and magnesium ion content), ensuring consistent performance in different water quality conditions.
• Easy Pearlescence Formation: No additional pearlescent agents are required; the product itself can generate a natural pearlescent effect, enhancing the visual appeal of end products.

4. Application Fields

• Facial Cleansers: Used as the main surfactant, it is easy to formulate, produces fine and rich foam, and is safe. It leaves the skin moisturized without tightness after washing.
• Body Washes: Reduces the irritation and pH value of soap-based body wash products, leaving the skin moisturized and soft after use, and is easy to rinse off.
• Hair Care Products: Effectively reduces the irritation of Sodium Laureth Sulfate (SLES) and minimizes SLES residue on hair, avoiding scalp irritation and dandruff caused by surfactant buildup.
• Soap Products: Serves as the main surfactant; mixing with other fillers, pigments, fragrances, or soap bases enables the production of various moisturizing soaps.

5. Packaging and Storage

• Packaging: Typically available in 25kg cardboard drums, 25kg woven bags, or 25kg cartons, with inner moisture-proof liners to prevent caking from moisture absorption.
• Storage: Store in a dry environment at a temperature below 40°C. Avoid direct sunlight and moisture. The shelf life is 24 months from the date of production.
