Science
Mechanism of Action
As a potent humectant, Isomalt functions by actively attracting and binding water molecules within cosmetic formulations and the skin's surface, effectively preventing transepidermal water loss. This sustained moisture retention deeply hydrates the skin, supports the maintenance of its natural moisture balance, and fortifies the skin barrier against environmental stressors. By promoting optimal hydration, Isomalt also contributes to improved skin elasticity and firmness. Furthermore, it exhibits notable antioxidant capabilities, helping to neutralize free radicals and thereby mitigate the visible signs of premature skin aging.

Stability
Isomalt demonstrates excellent thermal and chemical stability across a wide range of conditions, including notable resistance to acidic environments and microbial degradation. Its formulation compatibility is high, as it does not undergo browning reactions and remains inert with other cosmetic ingredients.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined Isomalt to be safe for use in cosmetic formulations. Testing up to 50% concentration showed no irritation in endpoint assessments. While undiluted Isomalt was classified as a slight irritant, this concentration is not typical for cosmetic application. Isomalt is also recognized as Generally Recognized As Safe (GRAS) by the FDA for food applications.
