ABSTRACT:
Thermally stable collagen gels formed by the addition of small amounts of neutralized slightly cross-linked polyacrylic acid. Thermally stable gels resulting from 0.3 to 4.0 percent by weight of collagen and 0.10 to 0.50 percent by weight of neutralized slightly cross-linked polyacrylic acid. The thermally stable gels are useful in wound care management. Further, synergistic effects are noted by the addition of 0.5 to 3.0 percent by weight of natural gums, particularly those containing glucuronic acid segments. Gelatin, a partially hydrolyzed collagen, behaves in a similar manner to collagen.
