Sodium Dehydroacetate, also known as the sodium salt of dehydroacetic acid, is a safe and highly effective preservative with strong inhibitory effects on mold, yeast, and bacteria. It is widely used in food processing, personal care products, and pharmaceuticals to extend shelf life and maintain product quality.

As a white to light yellow crystalline powder, Sodium Dehydroacetate is easily soluble in water and stable under normal conditions of use. It functions by disrupting microbial cell membranes and inhibiting enzymatic activity, thereby preventing spoilage and contamination in various products.
 

Key Features and Benefits:

Broad-spectrum antimicrobial: Effective against fungi, yeast, and Gram-positive bacteria.

Low toxicity: Recognized as safe by major global food and drug authorities.

Excellent stability: Maintains efficacy in acidic and neutral conditions and during heat processing.

Non-irritating and odorless: Suitable for sensitive applications like baby products and personal care.

Synergistic properties: Can be combined with other preservatives (e.g. potassium sorbate) to enhance effectiveness.

Applications:

Food Industry: Used in soy sauce, beverages, condiments, jelly, canned food, and meat products to prevent mold and spoilage.

Cosmetics & Personal Care: Employed in creams, lotions, shampoos, and makeup products as a mild, non-sensitizing preservative.

Pharmaceuticals: Added to oral and topical formulations to prevent microbial growth and ensure long-term stability.

Packaging Materials: Sometimes used as an antimicrobial agent in food packaging films and coatings.

 
Usage & Dosage:

The typical concentration ranges from 0.1% to 0.3% depending on the application and local regulatory limits. Its antimicrobial activity is most effective at pH 2–6.

Packaging & Storage:
Sodium Dehydroacetate is commonly packed in 25 kg fiber drums with inner plastic liners or other moisture-proof packaging. Store in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. Shelf life is generally 2 years under optimal conditions.
