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.

The rheology of a pre-neutralized, hydrophobically modified acrylic polymer was investigated by dynamic mechanical measurements using this methodological approach to establish its viscoelastic profile and stability in formulations. Properties of several polymer-containing emulsions were studied and their particle size distribution investigated by laser diffraction.
