Aldioxa

What is Aldioxa?

Aldioxa is a synthetic derivative of allantoin, created through chemical modification for enhanced stability in formulations. Chemically, it is 3-ureido-5,5-dimethylhydantoin, appearing as a white, odorless powder soluble in water. It belongs to the category of multifunctional cosmetic actives commonly incorporated into skincare, haircare, and personal care products like lotions, creams, and deodorants. In products, Aldioxa works by interacting with skin proteins to produce a tightening sensation, while also forming a protective layer that preserves moisture balance and inhibits microbial proliferation. This dual action supports its use in oil-control and freshness-maintaining formulas, drawing from its origins in pharmaceutical applications for soothing properties.
