Characterization of Multilamellar Vesicles for Cleansing Applications
By: Lawrence A. Hough, Denis Bendejacq and Tobias …
In the present article, the authors characterize a multilamellar vesicle (MLV) system used in personal care and verify its structure via X-ray scattering, rheology and fluorescence microscopy. This enabled the study of MLV formation to investigate bulk rheology characteristics. The results are presented here as application-relevant properties.
