CURCUMA ZEDOARIA ROOT WATER.

Valuable CAS 84961-49-9 / FRAGRANCE, SKIN CONDITIONING

Commonly known as White Turmeric hydrosol, this aqueous extract serves as a multi-functional botanical solvent that bridges the gap between hydration and antioxidant protection. It is particularly valued in precision skincare for its ability to deliver water-soluble phytonutrients while simultaneously reinforcing the skin's moisture barrier.

Antioxidant Skin Conditioning Hydration Booster Barrier Support

Science

This botanical water functions as a complex delivery system for sesquiterpenes, adenosine, and phenolic compounds. It neutralizes oxidative stress by scavenging free radicals, while its unique blend of nucleotides and amino acids supports cellular hydration. Furthermore, it exhibits natural antimicrobial properties and aids in maintaining the integrity of the dermal matrix by inhibiting degradative enzymes.
