Macrocystis Pyrifera (Kelp) Extract
What is Macrocystis Pyrifera (Kelp) Extract?
Macrocystis Pyrifera (Kelp) Extract originates from Macrocystis pyrifera, a massive brown seaweed thriving in nutrient-rich ocean waters along Pacific coasts. Harvested from its flexible fronds, the extract captures polysaccharides like alginates, along with trace minerals and fucoidans through aqueous or solvent processing. Primarily employed in cosmetics as a viscosity controlling agent, it works by hydrating and swelling in formulations to increase thickness. This creates stable gels and emulsions, preventing ingredient separation, enhancing spreadability, and delivering a silky feel. Common in lotions, creams, and masks, it supports product integrity without synthetic additives, contributing to consistent performance across various textures.
