General technical information

General information: sodium benzoate acts through undissociated benzoic acid, so it is most effective in acidic products (roughly pH 4.5 and below). Permitted uses and limits in food are set by the regulations of each market, such as FSSAI in India. This is general context about the substance, not a statement about a specific grade supplied by Sheetal Aromatics.
