Allium Sativum (Garlic) Extract
What is Allium Sativum (Garlic) Extract?
Allium Sativum (Garlic) Extract comes from the bulbs of the garlic plant, native to Central Asia and widely cultivated. Botanically, it belongs to the Amaryllidaceae family and contains bioactive sulfur compounds like allicin, which emerges from alliin via enzymatic reaction upon tissue damage, plus ajoene, diallyl disulfide, and flavonoids. In cosmetics, it appears in hair treatments, shampoos, and occasional skin products. As a skin conditioning agent, it helps preserve moisture, softness, and suppleness by forming a protective layer and delivering emollients. Its antimicrobial action stems from sulfur volatiles disrupting microbial cell membranes, while antioxidants neutralize free radicals from environmental stressors. Extracts are prepared through water, alcohol, or supercritical CO2 methods to isolate actives, ensuring stability and odor control in formulations for scalp and skin application.
