use

1, sodium propionate is acid type food preservative, its bacteriostatic effect by the environmental ph value. In the acidic medium of various types of mold, gram-negative bacillus or aerobic bacteria have a strong inhibitory effect. To prevent the production of aflatoxin have special effects on the yeast almost invalid. In the food industry, can be used for the preservation of pastry, the use of 2.5g --- kg (propionic acid).

2, cosmetics preservatives. On the mold, yeast and has a wide range of antibacterial effect. In the acidic solution of antibacterial effect is particularly evident. The amount of cosmetics to be added is usually not more than 2%.

3, other uses such as for: pesticides, fungicides, in the leather for the masking agent to improve the resistance of leather and tanning uniformity.

 

Packing: The product is packed in polyethylene film, the outer packing is polypropylene woven bag. Net weight 25KG.

Storage: ventilated and dry place, avoid the sun, away from the fire.
