The present invention relates to dentifrices in general and dentifrices free of chemically-derived foaming agents in particular. Particularly, the present invention relates to an all-natural dentifrice (e.g., toothpaste) comprising a concentration of glycyrrhizic acid that is suitable to work as a foaming agent. Even more particularly, the present invention relates to an all-natural dentifrice (e.g., toothpaste) that does not contain one or more of sodium lauryl sulfate, sodium lauroyl sarcosinate, cocomidopropyl betaine, sodium methyl cocoyl taurate, sodium cocoyl glutamate, poloxamer or any other chemically-derived foaming agent.
