Description

Sodium n-(2-Hydroxydodecyl)-n-Methyl-β-Alaninate is a high-purity, amphoteric surfactant derived from β-alanine. This compound is valued for its excellent mildness, foaming properties, and compatibility with other surfactants across a wide pH range. It is primarily utilized in the formulation of personal care and cosmetic products where gentle yet effective cleansing is required. Its unique structure provides enhanced skin feel and stability in complex formulations.

Application

• Primary surfactant in mild facial cleansers, shower gels, and baby shampoos.
• Key ingredient in sensitive skin formulations due to its low irritation potential.
• Foam booster and stabilizer in high-performance liquid soaps and syndet bars.
• Co-surfactant in conditioning shampoos and 2-in-1 products to improve combability and softness.
• Component in industrial and institutional (I&I) cleaning formulations requiring mildness.
• Used in cosmetic emulsifiers and solubilizers for essential oils and fragrances.

Quality Control

Our Sodium n-(2-Hydroxydodecyl)-n-Methyl-β-Alaninate is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for purity, active matter content, and performance characteristics relevant to the personal care industry. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is provided with every shipment to guarantee consistency and compliance.

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); the container must be kept tightly sealed after initial opening to prevent absorption of atmospheric moisture, which can affect product quality.
