Description

L-Glutamic Acid, n-(1-Oxododecyl)-, Monopotassium Salt(9Ci) is a specialized amino acid derivative, a monopotassium salt of an N-acylated glutamic acid. This compound is valued for its surfactant and emulsifying properties derived from its amphiphilic structure, combining a hydrophilic glutamic acid head with a lipophilic lauroyl chain. It is primarily utilized in the formulation of high-performance personal care products, cosmetics, and select industrial applications where mild, biodegradable surfactants are required.

Application

• Primary surfactant or co-surfactant in mild facial cleansers, shower gels, and shampoos.
• Key ingredient in cosmetic formulations such as creams, lotions, and makeup for its emulsifying and skin-conditioning properties.
• Used in the development of high-end skincare products targeting sensitive skin due to its amino acid-based, low-irritation profile.
• Potential application in industrial emulsifiers and dispersants for agrochemicals or coatings where biodegradability is a concern.
• As a biocompatible stabilizer in certain pharmaceutical and nutraceutical delivery systems.

Quality Control

Our L-Glutamic Acid, n-(1-Oxododecyl)-, Monopotassium Salt is produced under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for cosmetic and personal care applications. A comprehensive Certificate of Analysis (COA) documenting identity, purity, assay, and impurity profiles is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which may affect quality.
