Science
Mechanism of Action
Maltitol operates by attracting water molecules from the environment and the deeper layers of the epidermis, creating a hydrating reservoir within the stratum corneum. This mechanism helps to strengthen the skin barrier and maintain sustained hydration, contributing to improved skin elasticity and smoothness.

Stability
Maltitol demonstrates robust thermal and chemical stability, resisting browning reactions with amino acids at elevated temperatures. While weakly hygroscopic in its solid state, it actively absorbs atmospheric moisture at relative humidities exceeding 89% at 20°C. Its intrinsic weak acid properties mean it can ionize under highly alkaline conditions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded Maltitol and Maltitol Laurate are safe for use in cosmetic and personal care products, reporting no issues of concern. Dermal penetration is expected to be very low due to its high water solubility, and it was not found to be an eye or skin irritant. Its inclusion in the U.S. FDA's list of eligible food ingredients and absence of specific restrictions from the SCCS in Europe further underscore its general safety profile.
