Description

Calcium Dehydroacetate is the calcium salt of dehydroacetic acid, a versatile and effective preservative. This compound is valued for its broad-spectrum antimicrobial activity against molds, yeasts, and bacteria, enhancing product shelf-life and safety. It is primarily utilized by manufacturers in the food, cosmetics, and pharmaceutical industries where reliable, non-toxic preservation is critical.

Application

• Food Preservation: Used as an antimicrobial agent in baked goods, cheese rinds, and processed foods to prevent spoilage.
• Cosmetics & Personal Care: Acts as a preservative in creams, lotions, and makeup formulations to ensure microbiological stability.
• Pharmaceuticals: Employed as a preservative in topical ointments, creams, and certain liquid preparations.
• Animal Feed Additive: Helps prevent fungal growth and mycotoxin formation in stored feed ingredients.
• Industrial Applications: Can serve as a biocide in adhesives, paints, and other aqueous systems susceptible to microbial degradation.
• Fruit & Vegetable Coatings: Incorporated into edible coatings to extend the post-harvest life of fresh produce.

Quality Control

Our Calcium Dehydroacetate is produced under a strict quality management system. It can be manufactured to meet various industry standards, including FCC (Food Chemicals Codex) for food-grade applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and flow properties.
