Abstract
Self-complexing galactomannan gum blends which exhibit delayed gelling at acidic pH levels.
Claims3
A self-complexing blend consisting essentially of galactomannan gum, a water-soluble antimony salt in which the antimony ion is trivalent in amounts of from about 0.40 to 1.75% by weight based upon the weight of the galactomannan, and an oxidizing agent selected from the alkali metal periodate and permanganate salts in sufficient amounts to oxidize the trivalent antimony ion to a pentavalent antimony ion upon solvation.
