Description

Sodium n-Dodecanoyl-L-Serinate is a high-purity, amino acid-based anionic surfactant derived from L-serine and lauric acid. This compound matters for formulators seeking mild, biodegradable, and skin-compatible surfactants with excellent foaming and emulsifying properties. It is particularly needed by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating gentle cleansing products, shampoos, and topical formulations.

Application

• Primary Surfactant in Mild Cleansers: Ideal for facial cleansers, shower gels, and baby shampoos where skin mildness is paramount.
• Foam Booster & Stabilizer: Enhances and stabilizes foam in combination with other surfactants in liquid soaps and bubble baths.
• Cosmetic Emulsification: Used in the preparation of stable oil-in-water (O/W) emulsions for lotions and creams.
• Pharmaceutical Topicals: Employed as an excipient in medicated creams, ointments, and dermatological preparations for its good skin tolerance.
• High-End Personal Care: A key ingredient in premium skincare products targeting sensitive skin due to its amino acid origin.
• Biodegradable Formulations: Suitable for "green" or eco-friendly product lines requiring readily biodegradable components.

Quality Control

Our Sodium n-Dodecanoyl-L-Serinate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical characteristics are available upon request. We adhere to cGMP standards where applicable to support pharmaceutical and high-end cosmetic applications.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture which may lead to caking or degradation.
