b. optionally including a suspending agent for said activated inorganic mineral;

c. water

d. an oil;

e. an emulsifier;

f. optionally excluding caustic soda; and

g. optionally excluding hydrogen peroxide.

2 . The composition of claim 1 , wherein said suspending agent is a thickening agent.

3 . The composition of claim 2 , wherein said thickening agent is selected from the group consisting of: galactomannans; guar gum; locust bean gum; xanthan gum; para gum; cellulosics; hydroxypropyl methylcellulose; hydroxypropyl cellulose; carrageean; alginates; sodium alginates; potassium alginates; ammonium salt alginates; and a combination thereof.

4 . The composition of claim 1 , wherein said composition contains from about 5% to about 70% of said activated inorganic mineral, based upon weight of the composition.

5 . The composition of claim 1 , wherein said composition contains from about 0.05% to about 20% of said suspending agent, based upon weight of the composition.

6 . The composition of claim 1 wherein said composition contains from about 2% to about 55% of said oil based upon the weight of the composition.

7 . The composition of claim I wherein said composition contains from about 0.5% to about 20% of said emulsifier.

8 . The composition of claim 1 , wherein said oil contains a fatty acid, optionally further comprising rosin, optionally wherein the content of rosin in the composition is from greater than 0% to about 30% based upon weight of the fatty acid.

9 . The composition of claim 1 , wherein said oil is used to form an oil and water emulsion.

10 . The composition of claim 1 wherein said emulsifier is a surfactant.

11 . The composition of claim 8 , wherein said fatty acid contains a tall oil fatty acid.

12 . The composition of claim 1 , wherein the emulsifier is selected from the group consisting of: sorbitol derivatives; polysorbate 80; sorbitan monolaurate; polysorbate 20; ethoxylated alcohols; sodium laureth sulfate;polyethylene glycol; sulfate esters; sodium lauryl sulfate; and a combination thereof

13 . A composition comprising:

a. activated inorganic mineral;

b. xanthan gum,

c. tall oil fatty acid,

d. sodium lauryl sulfate; and

e. water.

14 . The composition of claim 13 wherein the composition comprises about 18 to about 47% of said activated inorganic mineral; about 0.3% to about 0.4% xanthan gum; about 22% to about 30% tall oil fatty acid; and about 2 to about 3% sodium lauryl sulfate.

15 . A method of removing ink from a cellulosic containing substance comprising:

(a) adding to the substance a composition comprising: (1) activated inorganic mineral, (2) water, (3) optionally a suspending agent for said activated inorganic mineral, and (4) optionally an emulsifier;

(b) optionally excluding the addition of caustic soda to the cellulosic containing substance; and

(c) optionally excluding the addition of hydrogen peroxide to the cellulosic containing substance.

16 . The method of claim 15 , wherein said cellulosic substance is located anywhere in a recycling process up through one or more flotation accepts.

17 . The method of claim 15 , wherein the composition is added to a paper recycling process in at least one of the following locations: a pulper; dilution stage; flotation cell thickening stage; and a kneader

18 . A method of removing ink from a cellulosic containing substance comprising:

(a) adding to the substance a composition comprising: (1) activated inorganic mineral, (2) xanthan gum, (3) tall oil fatty acid, (4) sodium lauryl sulfate, and (5) water;

(b) optionally excluding the addition of caustic soda to the cellulosic containing substance; and

(c) optionally excluding the addition of hydrogen peroxide to the cellulosic containing substance.

19 . The method of claim 18 wherein the composition comprises about 18 to about 47% of said activated inorganic mineral; about 0.3% to about 0.4% xanthan gum; 0.395% xanthan gum; about 22% to about 30% tall oil fatty acid; and about 2% to about 3% sodium lauryl sulfate.
