Aspartame

What is Aspartame?

Aspartame is an artificial sweetener, chemically a methyl ester of the dipeptide formed from aspartic acid and phenylalanine. Created in laboratories via enzymatic processes, it delivers sweetness 200 times greater than sucrose without adding calories. In cosmetics, it targets oral hygiene products like toothpastes, mouth rinses, and lip treatments. It works by interacting with taste receptors on the tongue and lips upon contact with moisture, providing a clean, sugar-like sweetness. Simultaneously, it neutralizes undesirable aftertastes from active ingredients such as fluorides or antimicrobials. Its heat stability and solubility suit both rinse-off and leave-on formulations, boosting sensory enjoyment to promote consistent product use without promoting dental issues linked to sugars.
