Abstract
Provided is a stabilized slurry composition having enhanced barrier properties. The slurry includes a pigment having a BET surface area of greater than 15 m2/g and a composite of a microcrystalline cellulose and carboxymethyl cellulose. The slurry can be used to formulate barrier coatings to be applied to the surface of a paper or paperboard product to enhance and improve the barrier properties of the product.
