ASPARTAME.

Questionable CAS 22839-47-0 / FLAVOURING

Aspartame is an artificial, non-saccharide dipeptide methyl ester sweetener primarily recognized for its use in food products. In precision skincare formulations, its application is generally limited to enhancing taste or texture, rather than providing direct dermatological benefits.

Summary

Science

Mechanism of Action

Aspartame functions as an intense sweetener by interacting with taste receptors. While it lacks documented direct therapeutic mechanisms on the skin, it may be utilized in cosmetic formulations, particularly lip and oral care, for flavouring. Furthermore, its inclusion in encapsulation processes can contribute to the stability, taste, color, or texture of other active ingredients.

Stability

Aspartame exhibits optimal stability in aqueous solutions within a pH range of 4.0 to 5.0, peaking at approximately pH 4.3 with a half-life of nearly 300 days at ambient temperature. Extreme pH conditions (strongly acidic or alkaline) lead to hydrolysis, yielding methanol and cleaving peptide bonds, thereby diminishing sweetness. Under neutral to alkaline conditions, cyclization to diketopiperazine can occur, also resulting in a loss of sweetness. Heat significantly reduces its stability and sweetening capacity.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The U.S. FDA classifies aspartame as Generally Recognized As Safe (GRAS) for food use under approved conditions, and the EFSA affirms its safety for human consumption within current exposure levels. While isolated reports of individual sensitivities, including skin alterations, exist, the FDA has deemed these reports inconsistent. Individuals with phenylketonuria (PKU) must monitor their aspartame intake due to its phenylalanine content. The Cosmetic Ingredient Review (CIR) has not reviewed aspartame for cosmetic use.
