Sunscreens – Canada and U.S. Regulatory Differences

Sunscreens – Canada and U.S. Regulatory Differences

Summertime has finally arrived and with it comes hot temperature and intense ultraviolet rays. Exposure to ultraviolet light is known to be associated with early skin aging and skin cancer. While the best protection from the sun is to avoid exposure altogether there are times when this is not possible. Using an appropriately regulated sunscreen can offer protection from the sun’s harmful rays.

If you are looking to market a sunscreen in Canada or the United States, there are a few things to consider.

Canadian Sunscreen Requirements

In Canada, sunscreens can be classified as either Natural Health Products (NHPs) or non-prescription drugs, depending on the ingredients they contain. Commonly used natural ingredients include titanium dioxide, zinc oxide, and p-aminobenzoic acid. Marketing a product containing these ingredients would require a Natural Product Number (NPN) unless the product also contains ingredients which are not naturally derived, such as avobenzone, oxybenzone, octinoxate or other recognized drug ingredients as outlined in the Natural and Non-Prescription Health Products Directorate’s (NNHPD’s) sunscreen monograph. For products that contain drug ingredients, a Drug Identification Number (DIN) would be required.

It is important to note that all Canadian sunscreen products must include a statement to the effect of “helps prevent sunburn” and display the appropriate Sun Protection Factor (SPF) value on the label. Companies are also permitted to market their sunscreen products with a ‘Broad Spectrum SPF’ value provided that test results demonstrate a critical wavelength of? 370 nm for the product.

There are however a few labeling statements that are not permitted by Health Canada. Statements that suggest the product completely blocks the penetration of the sun’s rays (e.g. sunblock) are not acceptable. Those that suggest the product helps to prevent cancer or photo-aging are also not permitted and the product cannot claim to filter out other UV rays apart from UVA/UVB. These are not the only non-permitted statements, but rather are those which are most commonly misused.

In summary, if you are looking to market a sunscreen in Canada, you need to determine whether it will be classified as a drug or an NHP, prepare the appropriate application and label your product according to the criteria as set out in the NNHPD sunscreen monograph and the appropriate set of governing regulations.

U.S. Sunscreen Requirements

Sunscreens in the United States are regulated as drugs through 2 pathways:

  1. The Over-the-Counter (OTC) monograph process outlined in 21 CFR part 330 and in accordance with the Sunscreen Innovation Act (SIA), or
  2. The new drug approval process outlined in 21 CFR part 314.

The United States Food and Drug Administration (FDA) has categorized sunscreen products by type and published several final rules. If you are looking to market a sunscreen product in the U.S., it is advisable to consult the FDA’s published final rules to verify if your product meets the indicated conditions. If the conditions as set out by the FDA are met and the product also complies with the FDA’s general regulations for OTC drugs then the FDA considers the sunscreen to be Generally Recognised as Safe and Effective (GRASE) and not misbranded.

Regulation through the OTC monographs was once the only option for sunscreen products, but in 2014, the FDA published the Sunscreen Innovation Act (SIA) to allow for an expedited review process for new sunscreen ingredients. The SIA functions to supplement the Time and Extent Application (TEA) regulation, as outlined in 21 CFR part 330.14(c), which together allows anyone (not only sponsors) to request that an active sunscreen ingredient be recognized as GRASE and not misbranded when used in accordance with the criteria set out in a final sunscreen order. This collaborative framework has allowed for a new process by which OTC active sunscreen ingredients or combinations of ingredients can be deemed GRASE and not misbranded when used according to the conditions set out in an administrative order.

In order to gain GRASE status for a new sunscreen ingredient, initial eligibility of the ingredient is determined by the FDA. If the ingredient is deemed eligible for review, data supporting the safety and efficacy of the ingredient is to be submitted by either the sponsor or the public.  If the provided evidence is deemed acceptable, a final GRASE determination in the form of an administrative order is made by the FDA within 60 days of data submission.

In summary, if you are looking to market a sunscreen product in the U.S., it is advisable to first check the OTC final rules for sunscreens and if your ingredient(s) is/are not present, then look into preparing a GRASE data submission.
