Quality Control

Our Sodium 1,4-Bis(2-Methylpentyl) Sulphonatosuccinate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for purity, activity, and performance. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and key physical-chemical parameters 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, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the original container tightly sealed to prevent absorption of atmospheric moisture which can affect product quality.
