Description

Sodium Hydroxymethylglycinate is a versatile and effective organic salt widely recognized for its preservative and antimicrobial properties. This compound matters for formulators seeking a broad-spectrum, formaldehyde-free alternative to traditional biocides, offering enhanced safety and compatibility. It is primarily needed by manufacturers in the personal care, cosmetic, and home care industries to ensure product integrity and shelf-life.

Application

• Primary preservative in rinse-off and leave-on cosmetic and personal care formulations such as shampoos, conditioners, and lotions.
• Stabilizing agent and biocide in household and industrial cleaning products, including liquid soaps and detergents.
• Used in wet wipes and toiletry products to prevent microbial contamination.
• Incorporated into hair dye and styling product formulations for enhanced stability.
• Potential application as a stabilizing agent in certain industrial fluid systems.

Quality Control

Our Sodium Hydroxymethylglycinate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and is suitable for cosmetic and personal care applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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 lead to caking or degradation.
