 Notice of Modification to the List of Permitted Preservatives  to Revise Permitted  Uses of Methylparaben, Propylparaben and their 
Sodium Salts – Reference Number: NOM/ADM -0171| 2 
 Summary  
Food additives are regulated in Canada under Marketing Authorizations  (MAs) issued by the Minister of 
Health and the Food and Drug Regulations  (Regulations) .  Approved food additives and their permitted 
conditions of use are set out in the Lists of Pe rmitted Food Additives  that are incorporated by reference in 
the MAs and published on the Canada.ca website.  
Health Canada’s Proposal to Revise Permitted Uses of the food additives Methyl Paraben, Propyl Paraben and 
their Sodium Salts in Various Foods  [NOP/ADP -0033] was published on November 15, 2019 , and was open to 
the public for comment for 75 days.  The objective of the proposed modifications was to ensure that 
approved food additive uses of parabens are up to date and reflective of actual uses by the food industry in 
foods sold in Canada.  As n o new scientific information was submitted to the Department  as a result of this 
Notice of Proposal , Health Canada has updated  the permitted conditions of use for  methylparaben , 
propylparaben, and their sodium salts as preservatives by modifying  Part 2 of the List of Permitted 
Preservatives  as shown in the table below.

The food s and maximum levels of use  shown in the above  table are the same modifications that were  
consulted on in Health Canada’s Proposal [ NOP/ADP -0033 ], with the exception that subitems M.1( 5) and 
P.5(6) shown above do not specify “chewing gum” as had been  originally proposed . This is because 
“unstandardized confectionery”  is a broad category that,  for the purpose of the Lists of Permitted Food 
Additives,  includes chewing gum . Finally, i n order to keep  the list of foods in alphabetical order  in the English 
version of the List , the subitems M.1(4), M.1(5), P.5(4), P.5(5) and P.5(6) were renumbered.  
Consequential Modification s to Part 2 of the List of Permitted Preservatives  
As p ut forward in Health Canada’s Proposal [ NOP/ADP -0033 ], the names “Methylparaben” and 
“Propylparaben” are now shown as synonyms in parentheses in the Column 1 entries for item M.1 methyl -p-
hydroxybenzoate and item P.5 propyl -p-hydroxybenzoate , respectively, as shown in the above table . Since 
this change would have made the entries for i tem M.2 Methyl Paraben and P.6 Propyl Paraben redundant, 
they have been removed. This minor modification does not result in any change s to the  permitted uses of 
these food additives .

In addition, entries shown in the first table above include the following revisions to the names of parabens:  
(1) the Greek letter “ρ”  was replaced  by an  italicized “ p” where the former had been used ; (2) the term  Notice of Modification to the List of Permitted Preservatives  to Revise Permitted  Uses of Methylparaben, Propylparaben and their 
Sodium Salts – Reference Number: NOM/ADM -0171| 5 
 “hydroxy Benzoate” was revised to "hydroxybenzoate" , and “hydroxy Benzoic Acid" revised to 
"hydroxybenzoic acid ”; and (3) the terms "Propyl Paraben" and "Methyl Paraben" were changed to 
"Propylparaben" and "Methylparaben" . 
Rationale  
As indicated in Health Canada’s Proposal [ NOP /ADP -0033 ], the Food Directorate identified parabens as a 
priority for safety assessment . As a result of Health Canada modifying Part 2 of the List of Permitted 
Preservati ves as shown in the tables above, t he permitted food additive uses of these parabens are more 
specific  and reflect current uses.  Potential exposure  to parabens as a result of the revised listings is expected 
to be well below the Acceptable Daily Intake (ADI) of 0-10 mg/kg bw that Health Canada applies to  methyl - 
and propyl -paraben and their sodium salts . 
Other Relevant Information  
The Food and Drug Regulations  require that food additives such as methyl -p-hydroxybenzoate 
(methylparaben), propyl -p-hydroxybenzoate (propylparaben), and their sodium salts , that do not have food -
grade specifications set out in Part B of the Regulations meet the food -grade specifications set out in the  
most recent edition of the  Food Chemicals Codex  or the Combined Compe ndium of Food Additive 
Specifications .  The Food Chemicals Codex  is a compendium of standards for purity and identity for food 
ingredients, including food additives, published by the United States Pharmacopeial Convention. The 
Combined Compendium of Food A dditive Specifications , which contains specifications prepared by JECFA, is 
published by the Food and Agriculture Organization of the United Nations.  
Notification – Summary of Comments  
No comments were received in response to Health Canada’s  Proposal to Revise Permitted Uses of the food 
additives Methyl Paraben, Propyl Paraben and their Sodium Salts in Various Foods  [NOP/ADP -0033], 
published on November 15, 2019 . 
Implementation and Enforcement  
The above modification s took effect  August 10, 202 1, the day they  were  published in  Part 2 of the  List of 
Permitted Preservatives .  
Regulat ions specific  to the use of parabens  as preservatives pre-date the List of Permitted Preservatives . 
These still appear in subparagraph B.21.005(b)(ii) and paragraph B.21.021(c) , and in Table XI of Division 16 of 
Part B of the Food and Drug Regulations . As indicated in the transition guide  published by the Food 
Directo rate in November 2012, the Lists are acknowledged as the official repository of approved additives. 
Health Canada intends to repeal the regulations for  parabens  from the Regulations under a Targeted 
Regulatory Review  that is part of the Agri -food and Aquaculture Roadmap.  
The Canadian Food Inspection Agency is responsible for the enforcement of the Food and Drugs Act and its 
associated regulations with respect to foods.   Notice of Modification to the List of Permitted Preservatives  to Revise Permitted  Uses of Methylparaben, Propylparaben and their
