Description

Sodium n-Dodecanoyl-L-Alaninate is a high-purity, anionic amino acid-based surfactant derived from L-alanine. This compound is valued for its excellent foaming, emulsifying, and mild cleansing properties, making it a superior alternative to traditional surfactants in sensitive formulations. It is primarily sought after by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating gentle, high-performance products.

Application

• Personal Care Cleansers: A key ingredient in mild facial cleansers, shower gels, and shampoos, especially for sensitive skin.
• Cosmetic Formulations: Used in makeup removers, shaving foams, and bubble baths due to its rich, stable lather.
• Pharmaceutical Preparations: Employed as a gentle surfactant in topical dermatological creams and medicated washes.
• High-End Detergents: Incorporated into premium liquid soaps and hand washes for its biodegradability and skin compatibility.
• Biochemical Research: Serves as a mild detergent in protein chemistry and membrane studies.

Quality Control

Our Sodium n-Dodecanoyl-L-Alaninate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for cosmetic and personal care applications. Certificates of Analysis (COA) documenting identity, purity, and related substances are available upon request to support your quality assurance protocols.

Storage

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