Description

Sodium Lauroyl Aspartate is a high-purity, mild anionic surfactant derived from lauric acid and aspartic acid. This compound is valued for its excellent foaming, cleansing, and emulsifying properties combined with exceptional skin and hair compatibility. It is a key ingredient for formulators seeking high-performance, biodegradable, and skin-friendly alternatives to traditional sulfates. Primary industrial users include manufacturers of personal care products, cosmetics, and high-end detergents.

Application

• Personal Care Cleansers: A primary surfactant in sulfate-free shampoos, facial cleansers, body washes, and shower gels, providing rich, stable foam with low irritation potential.
• Cosmetic Formulations: Used in cleansing milks, makeup removers, and sensitive skin formulations due to its mildness and ability to pair with cationic conditioners.
• Baby Care Products: An ideal surfactant for baby shampoos, bath products, and wipes where gentleness and safety are paramount.
• Oral Care: Employed as a foaming agent in mild toothpastes and mouthwashes.
• High-End Detergents: Incorporated into premium liquid hand soaps and fine fabric washes for its biodegradability and skin feel benefits.
• Biodegradable & "Green" Formulations: A cornerstone ingredient in eco-friendly and natural cosmetic lines, meeting demand for plant-derived, readily biodegradable surfactants.

Quality Control

Our Sodium Lauroyl Aspartate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, pH, and heavy metals are provided with every shipment. We support compliance with global standards including REACH, and our quality processes are designed to meet the needs of cosmetic and personal care industries.

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 original container must be kept tightly sealed after opening to prevent moisture absorption and caking.
