Detergent composition with antisoil and antiredeposition properties

Abstract

Detergent compositions of particular value in washing synthetic fabrics, especially polyester, inhibiting the redeposition of soil and imparting antisoil properties are based essentially on a combination of a nonionic surfactant and a hydroxybutylated methylcellulose of low molecular weight and having a relatively high degree of substitution.

We claim: 
     
       1. A detergent composition wherein the essential components thereof consist of (a) about 20 percent by weight of a C 8  -C 22  alkyl monoether of a polyethylene glycol of about 5-20 alkylene oxide units,   (b) about 60 percent of sodium sesquicarbonate,   (c) about 10 percent of sodium silicate having a ratio of SiO 2  /Na 2  O of about 2-3/l,   (d) about 0.1-2 percent of a hydroxybutylmethylcellulose having a DS of about 1.5-2.3 and an MS of about 0.01-0.6, .Iadd.and a viscosity of about 20-200 cps. in 2 percent aqueous solution at 20° C. .Iaddend.and   (e) about 10 percent of Na 2  SO 4 .   
     
     
       2. A detergent composition wherein the composition consists essentially of (a) about 20 percent by weight of an ethylene oxidepolypropylene glycol block copolymer,   (b) about 60 percent of sodium sesquicarbonate,   (c) about 10 percent of sodium silicate having a ratio of SiO 2  /Na 2  O of about 2-3/l,   (d) about 0.1-2 percent of a hydroxybutylmethylcellulose having a DS of about 1.5-2.3 and an MS of about 0.01-0.6, .Iadd.and a viscosity of about 20-200 cps. in 2 percent aqueous solution at 20° C. .Iaddend.and   (e) about 10 percent of Na 2  SO 4 .   
     
     
       3. A detergent composition which consists essentially of (a) about 20 percent by weight of a C 8  -C 22  alkyl monoether of a polyethylene glycol of about 5-20 alkylene oxide units,   (b) about 35 percent of sodium tripolyphosphate,   (c) about 1 percent of a hydroxybutylmethylcellulose having a DS of about 1.5-2.3 and an MS of about 0.01-0.6, .Iadd.and a viscosity of about 20-200 cps. in 2 percent aqueous solution at 20° C. .Iaddend.and   (d) about 44 percent of Na 2  SO 4 .   
     
     
       4. A detergent composition which consists essentially of (a) about 20 percent by weight of a C 8  -C 22  alkyl monoether of a polyethylene glycol of about 5-20 alkylene oxide units,   (b) about 25 percent of sodium nitrilotriacetate,   (c) about 10 percent of sodium silicate having a ratio of SiO 2  /Na 2  O of about 2-3/l,   (d) about 1 percent of a hydroxybutylmethylcellulose having a DS of about 1.5-2.3 and an MS of about 0.01-0.6, .Iadd.and a viscosity of about 20-200 cps. in 2 percent aqueous solution at 20° C. .Iaddend.and   (e) about 44 percent of Na 2  SO 4 .
