Description

Bismuth Subgallate Hydrate is an organometallic compound of bismuth and gallic acid, widely recognized for its astringent and hemostatic properties. This material is crucial for formulators requiring a reliable, high-purity active ingredient for pharmaceutical and personal care applications. It is primarily needed by manufacturers in the pharmaceutical, medical device, and cosmetic industries seeking to develop products with specific therapeutic or protective functions.

Application

• Pharmaceutical Active Ingredient: Key component in topical antiseptic and astringent preparations, such as hemorrhoid creams, ointments, and powders.
• Medical Device Coatings: Used in coatings for wound dressings and surgical pads to promote hemostasis and reduce minor bleeding.
• Cosmetic & Personal Care: Incorporated into formulations for skin protectants and deodorants for its mild antiseptic and odor-control properties.
• Veterinary Medicine: Employed in topical treatments for animals, similar to its human pharmaceutical applications.
• Chemical Intermediate: Serves as a precursor or reagent in the synthesis of other bismuth-containing compounds for research and development.

Quality Control

Our Bismuth Subgallate Hydrate is manufactured and tested under a strict quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for pharmaceutical and cosmetic applications. Certificates of Analysis (COA) with detailed test results are provided to guarantee traceability, consistency, and compliance with your specifications.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
