Carbamide peroxide—also an effective whitening agent—contains hydrogen peroxide at a ratio of 1:3. For example, a product with 30% carbamide peroxide has about 10% hydrogen peroxide. Hydrogen peroxide breaks down faster than carbamide peroxide, so it releases most of its whitening power within 30–60 minutes.
Does malic acid whiten teeth?
