Abstract:
1. A polymeric self-gelling composition that remains liquid at temperature between 4° C. and 15° C. and solidifies when heated between 30° C. and 60° C., said self-gelling composition comprising: a) an acidic water-based medium at a temperature between 4° C. and 15° C.; b) 0.1 to 10% by weight of a pH-gelling acid-soluble polymer, with the proviso that said polymer is free of chitosan, and wherein said polymer is collagen; and c) 0.1 to 10% by weight of a water-soluble molecule having a pKa between 6.0 and 8.4; wherein said self-gelling composition has a final pH ranging from 5.8 and 7.4, and forms a stable solid and homogeneous gel when heated to temperature of 30° C.-60° C.
