Description

Sodium n-Palmitoyl-L-Serinate CAS NO 58725-46-5 is a high-purity, anionic amino acid-based surfactant derived from L-serine and palmitic acid. This compound is valued for its excellent emulsifying, foaming, and mild cleansing properties, making it a superior and skin-friendly alternative to traditional surfactants. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking high-performance, biocompatible formulations.

Application

• Personal Care & Cosmetics: A key surfactant and emulsifier in facial cleansers, shower gels, shampoos, and shaving foams due to its mildness and skin compatibility.
• Skincare Formulations: Used in moisturizing creams, lotions, and serums for its emulsifying properties and potential skin-conditioning benefits.
• Pharmaceutical Topicals: Employed as an excipient in creams, ointments, and medicated washes where gentle yet effective surfactant action is required.
• Biodegradable Detergents: Serves as a primary surfactant in eco-friendly and high-end liquid detergents and dish soaps.
• Biochemical Research: Utilized as a specialty surfactant or lipid conjugate in membrane studies and biochemical assays.
• Industrial Emulsification: Applied in niche industrial processes requiring mild, amino acid-based emulsifiers.

Quality Control

Our Sodium n-Palmitoyl-L-Serinate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for cosmetic and pharmaceutical-grade applications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with every shipment.

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 opening to prevent absorption of atmospheric moisture, which can affect quality and performance.
