    摘要: The present invention relates to a process for producing a low endotoxin alkali chitosan, chitin, chitosan derivative or chitin derivative, and also to a process for producing low endotoxin neutral chitosan, chitosan salt and chitosan derivatives, and to the products of such processes. The process comprises contacting chitosan, chitin, chitosan derivative or chitin derivative with an alkali solution to form a mixture; leaving the mixture for a period of less than 1 hour and optionally drying the mixture. The low endotoxin alkali chitosan may be used in the manufacture of other useful chitosan based products.

    摘要: The invention provides: - A hydrophilic dehydrated partially purified bone replacement material of natural origin, wherein substantially all non-collagenous organic material is removed while inorganic, porous osseous structure and collagenous structure of natural bone are substantially preserved, characterized in that the bone replacement material contains 0.05 to 1.5 w/w % of at least one of a saccharide or a sugar alcohol, and 0.7 to 5.6 w/w % of a phosphate group selected from the group consisting of phosphate HPO4
    2- and H
    2 PO
    4
    - , this phosphate group being part of a physiologically acceptable salt and - a process for preparing a hydrophilic dehydrated partially purified bone replacement material.
