Title: STORAGE-STABLE AERATED GEL COMPOSITION AND A PROCESS FOR PRODUCING IT
Abstract:
A storage-stable aerated gel composition comprises 30 to 97 % by weight of water, 0.2 to 5 % by weight of a gelling agent selected from xanthan gum, sodium alginate and neutralised carboxyvinyl polymer and 2 to 5 % by weight of a fine particulate, hydrophobic silicone-treated silica having a surface area of from 80 to 300 m2/g. The composition is in the form of fine particles of an aqueous gel containing the water and gelling agent, the surfaces of which fine particles are coated with a coating of the finely particulate hydrophobic silica. The gel composition is prepared by mixing, under high shear conditions, the water and the fine particulate silica and then adding, to the resulting mixture, the gelling agent and mixing under high shear conditions.
