Rosmarinus Officinalis (Rosemary) Flower Extract

What is Rosmarinus Officinalis (Rosemary) Flower Extract?

Rosmarinus Officinalis Flower Extract comes from the blooms of the rosemary shrub, Rosmarinus officinalis, a hardy evergreen herb originating from Mediterranean climates. Harvested flowers undergo extraction processes like infusion or solvent methods to yield a concentrate rich in polyphenols, flavonoids, and volatile compounds. In cosmetics, it functions mainly to counteract oxidation in formulations containing oils or unstable actives, helping preserve product integrity and appearance over time. Its components also exhibit antimicrobial action, aiding in odor control within deodorants and body washes. Furthermore, the extract supports skin conditioning by promoting hydration retention and surface smoothness. Commonly featured in lotions, creams, and serums, it integrates well into diverse product types due to its versatile botanical profile and compatibility.
