Carbamide Peroxide 44%

Regarding the use of Carbamide Peroxide 44% directly on teeth, based on the information available for similar products:

• A high concentration like 95% Carbamide Peroxide (Solid) cannot be used directly and must be diluted to a concentration of no more than 17% for use in teeth whitening products.
• A lower concentration product, such as Carbamide Peroxide (Gel, 25% Carbamide Peroxide), is formulated as a gel that can be applied to teeth for 20-30 minutes.

Given that a 95% concentration requires significant dilution, a 44% concentration is also likely too high for direct application and would need to be diluted or formulated into a product with a lower, safe concentration before use on teeth. Always check the recommended usage rate and guidelines, especially those from regulatory bodies like the FDA, before using teeth whitening products.
