Description

Glycolic Acid Calcium Salt CAS NO 26257-13-6 is the calcium salt derivative of glycolic acid, offering a stable, solid form of this important α-hydroxy acid. This compound is valued for its controlled release of glycolate ions, which are key in applications requiring pH buffering, chelation, or gentle exfoliation. It serves as a critical raw material for formulators in the personal care, pharmaceutical, and industrial cleaning sectors seeking effective yet mild performance.

Application

• Cosmetic & Personal Care Ingredients: Used as a pH adjuster, buffering agent, and active in skincare formulations for its gentle exfoliating and moisturizing properties.
• Pharmaceutical Intermediates: Acts as a precursor or stabilizing agent in the synthesis of certain active pharmaceutical ingredients (APIs).
• Industrial Cleaning & Descaling: Employed in specialty cleaning formulations where its chelating action helps remove mineral scales and deposits without excessive acidity.
• Agricultural Chemicals: Can be utilized as a component in certain fertilizer or plant treatment formulations to aid in nutrient delivery.
• Laboratory Research & Development: Serves as a standard or reagent in chemical research involving hydroxy acids and their salts.

Quality Control

Our Glycolic Acid Calcium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metals, and loss on drying are provided to guarantee consistent quality and traceability for your B2B applications.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
