In a new patent application, PZ Cussons inventors explain how unstructured personal cleansing compositions are challenged to suspend insoluble materials such as hydrophobic oils or waxes, scrub particles or encapsulates. These materials typically sink to the bottom or rise to the top of a formula, depending on their density. As a consequence, such compositions demonstrate low storage stability.
