Stevioside

What is Stevioside?

Stevioside is a naturally occurring steviol glycoside extracted from the leaves of the Stevia rebaudiana plant, native to South America. This botanical compound is renowned for its intense sweetness, approximately 250 times that of sucrose, without contributing calories. Chemically, it consists of a steviol aglycone bound to glucose molecules. In cosmetic formulations, particularly oral care products such as toothpastes and mouthwashes, stevioside functions primarily as a flavoring and masking agent. It activates sweet taste receptors on the tongue, imparting a clean, pleasant taste that improves overall product palatability. Additionally, it neutralizes bitter or medicinal notes from active ingredients like fluorides, enhancing sensory appeal. As a plant-derived alternative to synthetic sweeteners, it aligns with preferences for natural cosmetic ingredients while maintaining stability in aqueous formulations.
