Description

Sodium Dehydroacetate is the sodium salt of dehydroacetic acid, a highly effective preservative and antimicrobial agent. This compound is valued for its broad-spectrum activity against bacteria, yeasts, and molds, making it a critical component for product stability and shelf-life extension. It is primarily utilized by manufacturers in the food, cosmetics, and pharmaceutical industries seeking reliable, compliant preservation solutions.

Application

• Food Preservation: Used as a preservative in baked goods, cheese spreads, fermented beverages, and prepared salads to inhibit microbial growth.
• Cosmetics & Personal Care: Incorporated into creams, lotions, shampoos, and sunscreens to prevent spoilage and ensure product safety.
• Pharmaceuticals: Serves as a preservative in topical ointments, liquid formulations, and other non-sterile medicinal products.
• Animal Feed: Applied as a fungistatic agent in feed and silage to prevent mycotoxin formation.
• Industrial Applications: Functions as a biocide in adhesives, paints, and metalworking fluids to control microbial contamination.
• Agriculture: Used in post-harvest treatments for fruits and vegetables to reduce decay during storage and transport.

Quality Control

Our Sodium Dehydroacetate is manufactured under strict quality management systems. It can be supplied in grades compliant with FCC (Food Chemicals Codex) and cosmetic standards, ensuring suitability for sensitive applications. Every batch undergoes rigorous analytical testing. Certificates of Analysis (COA) documenting purity, identity, and specific 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 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 reduced efficacy.
