There is no reason to believe that products based on the Sorbay technology are unsafe. The three actives (citric acid, sodium lauryl sulfate, and tannic acid) upon which the Sorbay technology depends are found in nature. Clinical trials, and independent health and safety (toxicological) study, and an examination of the structure of a human tooth after five years of exposure to Sorbay lozenges have been conducted without the emergence of a single safety issue.
The only difference between the SorbayPC lozenge and the SorbayPOC mist is the formulation and method of delivery of the technology.
"Isomalt", the sugar-free lozenge base, Acesulfame K, the sweetness enhancer, and citric acid are commonly used in foods and widely accepted as safe. The U.S. Food & Drug Administration (FDA) has determined that all three are safe for human ingestion and may be used as food additives in a variety of foods. The remaining two ingredients, tannic acid and sodium lauryl sulfate have FDA approved uses in foods, however with restrictions as to amounts and vehicles.
Sodium lauryl sulfate is commonly found in toothpaste. It serves to dislodge contaminates from oral surfaces. The products based on the Sorbay technology contain 1/750th of the amount reported to be safe for children.
The ingestion of moderate amounts of tannic acid is also considered to be safe. In a recent look at the implications of dietary tannic acid, a committee of the National Research Council found nothing troubling about the human consumption of foods containing tannic acid. In fact, tannic acid was lauded for its antioxidant properties.
