A non-aqueous slurry comprising:
- (a) one or more water soluble polymers selected from the group consisting of xanthan gum, gellan gum, algin, locust bean gum, derivatized locust bean gum, carrageenan, guar gum, derivatized quar gum, cellulosic materials, succinoglucans, polyacrylamides, starch, and starch derivatives;
- (b) polyalkylene glycol;
- and a
- (c) a slurry stabilizer comprising an amine phosphate ester salt.
A non-aqueous slurry consisting essentially of:
- (a) about 0.1 to about 50.0 percent by weight xanthan gum;
- (b) about 40 to about 98.8 percent by weight polyethylene glycol;
- and
- (c) about 0.1 to about 10.0 percent by weight of the reaction product of 2-amino-2-methyl-1-propanol with poly(oxy-1-2-ethanediyl),.alpha.-9-octadecenyl-.omega.-hydroxy-(Z)-phospha te;
- wherein the sum of the weight percentages of (a), (b) and (c) is 100 percent.
A composition comprising environmental chemical, agricultural chemical, paper chemical, textile chemical, paint, hair spray, gelatin substitute, ceramic material, cleaning composition, polish, ink, fire-fighting chemical, metal-working chemical, adhesive chemical, explosive chemical, binder chemical for sand, ores or coal or oil field chemical which includes a non-aqueous slurry comprising:
- (a) one or more water soluble polymers selected from the grout consisting of xanthan gum, gellan gum, algin, locust bean gum, derivatized locust bean gum, carrageenan, quar gum, derivatized quar gum, cellulosic materials, succinoglucans, polyacrylamides, starch, and starch derivatives;
- (b) polyalkylene glycol;
- and a
- (c) a slurry stabilizer comprising an amine phosphate ester salt.
