Abstract
Official abstract text for this publication.
An aqueous composition comprising at least one surfactant; a suspending agent comprising micro fibrous cellulose; 10 to 600 ppm of an alkaline earth metal ion, and water. The composition can be used to structure surfactant systems to suspend material in the composition.
First claim
Opening claim text (preview).
What is claimed is: 1. An aqueous composition comprising a) at least one surfactant; b) a suspending agent comprising microfibrous cellulose; c) 10 to 600 ppm of a calcium ion; and d) water, wherein the composition has a yield stress of at least 0.7 Pa. 2. The composition of claim 1 , wherein the amount of calcium ion is 75 to 300 ppm. 3. The composition of claim 1 , wherein the suspending agent further comprises xanthan gum and carboxymethyl cellulose. 4. The composition of claim 1 , wherein the suspending agent comprises a 6:3:1 blend by weight of microfibrous cellulose:xanthan gum:carboxymethyl cellulose. 5. The composition of claim 1 further comprising suspended material. 6. The composition of claim 5 , wherein the suspended material is non-density matched suspended material. 7. The composition of claim 1 , wherein the calcium ion is provided by at least one salt chosen from halide salts, sulfate salts, citrate salts, acetate salts, formate salts, or nitrate salts.
