name: Sodium benzoate
CAS:532-32-1
EINECS: 208-534-8
Sodium benzoate is mostly white particles, odorless or microstrip benzoin smell, taste slightly sweet; soluble in water (room temperature) about53.0g/100ml, PH is about 8; sodium benzoate is acidic in nature, without sterilization, in alkaline medium bacteriostasis; its anti-corrosion best PH is 2.5-4.0, solution the sterilization effect in PH5.0 5% is not very good. Sodium benzoate lipophilicity is large, easy to penetrate the cell membrane into the cell body, interfere with the cell membrane permeability, inhibit absorption cell membrane for amino acid; into the alkali storage cells in vivo ionizing intracellular acidification, and inhibit the activity of respiratory enzymes in cells, prevent the acetyl coenzyme A condensation reaction, so as to food preservation objective.
Applications:
[1] mainly used as food preservatives, also used for preparing drugs, dyes etc.
[2] for the pharmaceutical industry and the use of plant genetic research, also used as dye intermediates, fungicides and preservatives
[3] use of preservatives; anti microbial agent.
[4] the use of sodium benzoate is also important acid food preservative. When in use into effective form of benzoic acid. Scope and quantity of use see benzoic acid. In addition, also can be used as feed preservative.
[5] use the products used as food additives (preservative), pharmaceutical industry fungicides, of industrial dyes mordant, plastic industrial plasticizers, also used as intermediates in Organic Synthesis Perfume etc..
[6] use of serum bilirubin test used as cosolvent, food additive (preservative), pharmaceutical industry fungicides, of industrial dyes mordant, plastic industrial plasticizers, also used as intermediates in Organic Synthesis Perfume etc..
