Can I add more than one Class II chemical preservative to the same product?


Updated by SFA
Where two or more permitted Class II chemical preservatives are used in the same product, the sum of their respective percentages must not exceed 100%, as stipulated under Regulation 19(3)(b)(ii) of the Food Regulations. The percentage use level for each Class II chemical preservative in an admixture may be calculated using the formula below: [Amount of permitted Class II chemical preservative added (ppm) / Maximum permitted level of Class II chemical preservative (ppm)] x 100% = Y Example: An admixture of permitted Class II Chemical Preservatives, (Chemical X + Chemical Y + ….) when added to the same food product must be less than 100% Y1 + Y2 + Y3 +… ≤100%
