What is Sodium Dehydroacetate CAS 4418-26-2 ？

Sodium dehydroacetate is a white crystalline powder that is easily soluble in water. It exhibits weak acidity in water and can release SO2 gas under acidic conditions. Sodium dehydroacetate is a broad-spectrum and highly antibacterial food preservative, with particularly strong inhibitory ability against mold and yeast. At the same dosage, the antibacterial effect is several times or even tens of times higher than the widely used sodium benzoate and potassium sorbate. What is particularly valuable is that it has little inhibitory effect on acid producing bacteria, especially lactic acid bacteria.

Application

1.Sodium dehydroacetate is an antibacterial agent with high safety, wide antibacterial range, and strong antibacterial ability. It is less affected by the acidity or alkalinity of food and can maintain high antibacterial efficacy under acidic or slightly alkaline conditions. Its antibacterial ability is superior to sodium benzoate, potassium sorbate, calcium propionate, etc., making it an ideal food preservative.
2. Sodium dehydroacetate can be used for metal surface treatment, degreasing, and rust prevention on metal surfaces,
3. Sodium dehydroacetate can also be used for chemical analysis and the preparation of mordants.
4.Sodium dehydroacetate is also used in the fields of papermaking, leather, coatings, cosmetics, etc
