Abstract:
A method for preparing a composition, comprising a) reducing mother-of-pearl into powder with grain size distribution ranging between about 1 and about 300 mum; b) placing the obtained powder in close contact with an extracting agent in the form of a hydroglycol solution of at least a collagen, of at least a proteoglycan or a mixture thereof; then c) in collecting the extraction mixture, formed by the close contact, constituting the desired composition.
