Rosmarinus Officinalis (Rosemary) Leaf Extract

Rosmarinus Officinalis Leaf Extract is derived from the leaves of the Mediterranean rosemary herb and is particularly valued for its high content of rosmarinic acid, carnosic acid, and carnosol—potent polyphenolic antioxidants that provide exceptional free radical scavenging activity. Formulators choose this extract not only for its antioxidant properties but also for its natural antimicrobial activity, which can extend product shelf life and reduce reliance on synthetic preservatives. The extract's dual functionality as both a skin-conditioning agent and preservation booster makes it especially popular in natural and clean beauty formulations.
