Description

Sodium Isethionate is the sodium salt of isethionic acid, a versatile and highly water-soluble organic compound. It serves as a key mild anionic surfactant and conditioning agent, prized for its excellent skin and hair compatibility. This makes it an essential ingredient for manufacturers in the personal care and detergent industries seeking high-performance, gentle formulations.

Application

• Primary Surfactant in Syndet Bars: A fundamental building block for synthetic detergent (syndet) and combo bars, providing mild cleansing with a rich, stable lather and improved skin feel.
• Hair Care Formulations: Used in shampoos, conditioners, and hair dyes as a gentle cleansing agent and antistatic conditioner, enhancing manageability and shine.
• Facial Cleansers & Body Washes: Incorporated into liquid and cream-based cleansers for its exceptional mildness and low irritation potential, suitable for sensitive skin.
• Baby Care Products: Ideal for baby shampoos, soaps, and washes due to its proven mildness and high safety profile.
• Pharmaceutical & Cosmetic Preparations: Acts as a solubilizing agent, hydrotrope, and stabilizer in topical creams, lotions, and medicated cleansers.
• Industrial & Household Cleaners: Functions as a wetting agent, dispersant, and mild surfactant in specialty cleaning formulations.
