Isomalt

Isomalt is a sugar alcohol (polyol) derived from sucrose, used in cosmetics as a humectant and skin-conditioning agent.

What it is

Isomalt is a sugar alcohol produced from sucrose and best known as a food sweetener, but in cosmetics it functions as a humectant that helps attract and hold moisture. It can contribute to a smooth, hydrated skin feel and to the overall conditioning of a formula. In sunscreens it is a supporting moisturizing ingredient and plays no role in UV filtering.

Safety & warnings

Isomalt is a well-characterized sugar alcohol with a long history of food use and is considered gentle and non-sensitizing on skin at cosmetic levels.

Origin & sourcing

Derived from sucrose (beet or cane sugar) through enzymatic conversion and hydrogenation.
