Abstract:
A superabsorbent formulation is described for absorbing liquids (for example in an ostomy, incontinence or woundcare application), the formulation comprising superabsorbent (100 pbw), silica (3-20 pbw), water (0.5-8 pbw) and glycerol (5-40 pbw). The superabsorbent and silica are mixed together in a first production stage (10), to coat the superabsorbent particles with silica. The glycerol and water are added during a second production stage (12). The effect of the silica is to increase the amount of glycerol and water which can be taken up in the formulation, thereby producing a product with greater structural stability when consolidated (compressed).
