Description

Calcium Thioglycolate Trihydrate is a key inorganic salt of thioglycolic acid, widely recognized for its role as a depilatory agent and a versatile reducing agent in chemical synthesis. Its importance lies in providing a stable, solid source of thioglycolate ions, which are crucial for breaking disulfide bonds in various industrial and cosmetic processes. This product is essential for manufacturers in the personal care, pharmaceutical, and chemical synthesis sectors seeking a reliable and effective ingredient for depilatory creams, permanent wave solutions, and specific reduction reactions.

Application

• Cosmetic & Personal Care Depilatories: The primary application is as the active ingredient in cream and lotion hair removal products, where it breaks keratin disulfide bonds.
• Hair Care Products: Used in certain permanent wave (perm) solutions and hair straightening treatments as a reducing agent.
• Chemical Synthesis: Serves as a specialized reducing agent and a source of thioglycolate anions in organic and inorganic synthesis.
• Pharmaceutical Intermediates: Employed in the synthesis of certain active pharmaceutical ingredients (APIs) requiring thioglycolate functionality.
• Analytical Chemistry: Can be used as a reagent in specific titrimetric and spectrophotometric analytical methods.
• Textile & Leather Processing: Acts as a reducing agent in specific dyeing and finishing processes.

Quality Control

Our Calcium Thioglycolate Trihydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metals, and loss on drying are available upon request. We can supply material compliant with cosmetic-grade standards and tailor specifications to meet specific customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed after opening to minimize exposure to air and moisture. Keep away from strong oxidizing agents.
