Low viscosity stable non-aqueous suspension containing organophilic clay and low density filler

A heavy duty built liquid thickened non-aqueous laundry detergent composition comprising

• from about 30 to about 40% of a liquid nonionic surfactant which is a mixed ethylene oxide-propylene oxide condensate of a fatty alcohol having from about 12 to about 18 carbon atoms;
• from about 25 to about 40% of alkali metal phosphate detergent builder salt;
• from about 5 to about 12% of an alkylene glycol ether solvent as a viscosity control and anti-gelling agent;
• from about 2 to about 20% of a peroxide bleaching agent;
• from about 0.1 to about 8% of a bleach activator;
• up to about 2% of enzymes;
• up to about 10% of soil suspending, anti-redeposition and anti-yellowing agents;
• up to about 5% of high complexing power sequestering agent;
• up to about 2% each of one or more of colorants, perfumes and optical brighteners;
• the solid components of said composition having an average particle size in the range of from about 2 to 10 microns, with no more than about 10% of the particles having a particle size of more than 10 microns;
• from about 0.05 to about 6% of inorganic or organic filler particles having a density of from about 0.01 to 0.50 g/cc and an average size particle diameter of from about 20 to 80 microns;
• from about 0.2 to about 0.7% of an organophilic modified smectite clay in which from about 10 to 100% of the available base exchange capacity of the smectite clay is replaced by an organic cationic nitrogen compound having at least one long chain hydrocarbon with from about 8 to about 22 carbon atoms;
• said composition, after the addition of said filler particles having a viscosity in the range of from about 500 to 5,000 centipoise;
• and
• from about 0.1 to 3% by weight of lecithin, such that the viscosity of the composition is lowered to within the range of from about 200 to 1,000 centipoise.

A non-aqueous liquid fabric treating composition which comprises (a) a non-aqueous liquid comprising a non-ionic surfactant;

• (b) functionally active laundry additive solid particles including at least one of detergent builders and bleaching agents suspended in said non-aqueous liquid;
• (c) from about 0.1 to 10% by weight of the remaining composition of a low density filler having a density in the range of from about 0.1 to 0.5 g/cc, and an average particle size diameter of from about 5 to about 200 microns, said amount being sufficient to substantially equalize the density of the continuous liquid phase and the density of the suspended particle phase inclusive of the low density filler and the suspended functionally active solid particles, thereby inhibiting settling of the suspended particles while the composition is at rest, and (d) from about 0.1 to 1.0% by weight, based on the total composition, of an organophilic modified smectite clay in which from about 10 to 100% of the available base exchange capacity of the smectite clay is replaced by an organic cationic nitrogen compound having at least one long chain hydrocarbon with from about 8 to about 22 carbon atoms, the amount of said organophilic clay being sufficient to inhibit phase separation when the composition is subjected to strong vibrational forces;
• and (e) from about 0.1 to 3% by weight of lecithin or an alkylamine-, alkenylamine-, alkylammonium- or alkenylammonium-phosphate ester of glycol, polyglycol or glycerol, having at least one long chain fatty carboxylic acid ester group in the molecule, said amount being sufficient to reduce the viscosity and further stabilize the rheological properties of the composition.
