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.
Claims10
A method of removing cerumen from the ear canal comprising the steps of:
- (1) instilling a composition containing as an active agent a cerumen permeating and complexing effective amount of substantially uncomplexed cyclodextrins;
- (2) allowing said composition containing cyclodextrin to remain in the ear canal for sufficient time for said composition to permeate cerumen, and
- (3) removing said composition containing cyclodextrin with complexed cerumen from the ear canal.
