Uses
  
  1 propionate acid type food preservatives, its inhibitory effect impact on the environment by the ph value. In acidic medium for various types of fungi, aerobic gram-negative bacillus subtilis or strongly inhibited. Prevention of aflatoxin produced streptozotocin have effects on yeast almost ineffective. In the food industry, can be used to save, use the amount of pastry 2.5g / kg (with propionic acid).
  
  2 cosmetic preservatives. To mold, yeast and has a broad antibacterial activity. In acidic solution quality in the antibacterial effect is particularly evident. To add the amount of cosmetics usually not more than 2%. Insecticide, Fungicide. Determination of transaminases. In leather as a masking agent, in order to improve the uniformity of alkali force and leather tanning.
