It was found that tetrakis hydroxymethyl phosphonium mainly linked with amino groups of collagen and to a lesser extent with hydroxyl groups and amido groups. The combination capacity of tetrakis hydroxymethyl phosphonium with hydroxyl groups and amido groups changed with pH and reached a peak at pH8.0.
