Signal Bio Natural Whitening toothpaste is a 75 ml, organic-labeled oral care gel from Unilever that promises natural tooth whitening. The formula blends peppermint leaf water, fluoride, charcoal powder and zinc citrate for fresh breath, enamel strengthening, and a whitening effect, and it uses stevia as a sugar-free sweetener. Nonetheless, it also includes synthetic components such as benzyl alcohol, sodium benzoate, fragrance and a surfactant (decyl glucoside), which may irritate sensitive mouths, and the presence of fluoride requires careful dosing to avoid ingestion.
