Overcoming Active Recrystallization and Discoloration
Centella Asiatica's signature pentacyclic triterpenes—namely Madecassic Acid, Asiatic Acid, and Asiaticoside—possess extremely high melting points and rigid crystalline structures. In standard emulsion systems, high active concentrations frequently precipitate out over shelf life, causing gritty textures, localized skin irritation, and noticeable formula separation.
At Guangzhou Cairas Beauty Products Co., Ltd., our senior formulation engineers utilize micro-liposomal encapsulation and biocompatible polar lipid solubilization. By micro-shearing botanical actives at precise thermal boundaries in our vacuum emulsifying machines, the triterpenes remain fully integrated inside the lipid bilayer, delivering high bioavailability, silky skin absorption, and 3-year color stability without oxidation or browning.
