Description

Calcium Bis(4-Hydroxybenzoate) is the calcium salt of 4-hydroxybenzoic acid, a compound valued for its preservative and stabilizing properties. This material is crucial for formulators requiring a metal-based, broad-spectrum antimicrobial agent with good thermal stability. It is primarily sought by manufacturers in the food, pharmaceutical, and personal care industries for its efficacy in preventing microbial growth and extending product shelf life.

Application

• Food Preservative: Used as an antimicrobial agent in baked goods, dairy products, beverages, and processed meats to inhibit mold, yeast, and bacteria.
• Pharmaceutical Excipient: Functions as a preservative in topical creams, ointments, oral suspensions, and liquid formulations to ensure product stability.
• Cosmetics & Personal Care: Incorporated into creams, lotions, and makeup as a stabilizer and preservative to prevent spoilage.
• Industrial Preservative: Applied in adhesives, paints, and functional fluids where microbial degradation is a concern.
• Animal Feed Additive: Utilized to preserve the quality and nutritional value of feed by preventing fungal growth.

Quality Control

Our Calcium Bis(4-Hydroxybenzoate) is manufactured under a strict quality management system. Each batch is tested to ensure it meets specifications for identity, purity, and heavy metal content, aligning with standards such as FCC (Food Chemicals Codex) and relevant pharmacopoeial guidelines for pharmaceutical grades. Certificates of Analysis (COA) are available upon request to support your regulatory and quality assurance needs.

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, which can affect product quality.
