Erucamidopropyl Hydroxysultaine

Updated: 2026-08-06

Overview

Erucamidopropyl Hydroxysultaine is a zwitterionic surfactant derived from erucic acid, a fatty acid found in rapeseed oil. It is known for its mildness and excellent foaming properties, making it a popular choice in personal care formulations. The compound is biodegradable and exhibits low irritation potential, which is particularly beneficial for sensitive skin applications such as baby care products. Its unique structure allows it to function effectively in a wide pH range, enhancing its versatility in various cosmetic and industrial applications. The surfactant is also compatible with other anionic, cationic, and nonionic surfactants, making it a valuable component in complex formulations.

Physical and Chemical Properties

Erucamidopropyl Hydroxysultaine typically appears as a clear to pale yellow viscous liquid with a density of approximately 1.05 g/cm³. It is highly soluble in water and polar organic solvents, which facilitates its incorporation into aqueous-based formulations. The molecular weight is around 477.75 g/mol, and its structure includes both hydrophilic and hydrophobic moieties, contributing to its surfactant properties. The compound is stable under normal storage conditions but should be protected from extreme temperatures and prolonged exposure to sunlight to prevent degradation. Its zwitterionic nature ensures excellent compatibility with a wide range of ingredients, enhancing its utility in diverse applications.

Main Applications

Erucamidopropyl Hydroxysultaine is predominantly used in the personal care industry, particularly in shampoos, body washes, and facial cleansers, where its mildness and foaming capabilities are highly valued. It is also a key ingredient in baby care products due to its low irritation potential and gentle cleansing properties. Beyond personal care, this surfactant finds applications in industrial cleaning formulations where biodegradability and mildness are required. Its compatibility with other surfactants allows it to be used in complex blends to achieve specific performance characteristics, such as enhanced foam stability or improved skin feel.

Safety and Storage

Erucamidopropyl Hydroxysultaine is generally regarded as safe for use in cosmetic and personal care products. However, as with all surfactants, it is advisable to avoid direct contact with eyes and prolonged skin exposure to prevent potential irritation. Proper storage in a cool, dry place away from direct sunlight is recommended to maintain its stability and efficacy. Manufacturers should ensure that the product is handled in accordance with standard safety protocols, including the use of personal protective equipment (PPE) when necessary. Regulatory compliance, including adherence to regional cosmetic safety guidelines, is essential for its use in commercial formulations.

B2B Procurement Guide

When procuring Erucamidopropyl Hydroxysultaine, buyers should verify the CAS number, purity, and compatibility with other surfactants in their formulations. It is advisable to request technical data sheets (TDS) and safety data sheets (SDS) from suppliers to ensure the product meets specific requirements. The reference price range is approximately $5-$15 per kilogram, depending on purity, volume, and supplier. Buyers should also consider the supplier's reputation, delivery timelines, and compliance with international quality standards such as ISO or GMP. Bulk procurement may offer cost advantages, but storage capacity and shelf life should be factored into purchasing decisions.
