Abstract
This invention relates to methods for delipidation of skin or hair through the use of cyclodextrins and cyclodextrin derivatives such as hydroxypropyl .beta.-cyclodextrin. The invention also relates to cerumen removal methods involving introduction of cyclodextrins to the ear canal, followed by complexation of the cyclodextrin with cerumen components, and removal of the resulting cyclodextrin complexes. The cyclodextrin components are used in a substantially oil-free powdered or aqueous formulation without detergents, soaps, solvents, oils or other lipid-like agents.
