Abstract: Fatty acid vesicles (FAVs) with a hollow core-shell structure can entrap reactive molecules.In order to improve the defect that FAVs can form near its pKa only so as to enlarge their application field,mild anionic surfactant potassium alkyl phosphate (MAPK) was added to conjugated linoleic acid (CLA).The pH window for vesicles formation was characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM).It was found that hybrid FAVs can be formed at neutral to acidic environment by blending CLA with 9% MAPK without significant change of morphology and particle size of the original FAVs,and the pH window of the hybrid FAVs has a tendency to gradually broaden along with increasing of the dosage of MAPK.The result shows the potential application of FAVs in fields of cosmetics and personal health care products.

Key words: potassium alkyl phosphate, fatty acid vesicles, cosmetics, personal health care products
