Abstract

Aqueous, liquid compositions which comprise a surfactant, a bleaching agent and magnesium sulfate, wherein the bleaching agent comprises a particulate peroxocarboxylic acid which may optionally be coated, along with uses therefor are described.

Claims

exact text as granted — not AI-modified
1 - 10 . (canceled) 
   
   
       11 . An aqueous, liquid composition comprising a surfactant, a bleaching agent and magnesium sulfate, wherein the bleaching agent comprises a particulate peroxocarboxylic acid. 
   
   
       12 . The composition according to  claim 11 , wherein the particulate peroxocarboxylic acid is present in an amount of 1% to 25% by weight, based on the composition. 
   
   
       13 . The composition according to  claim 11 , wherein the particulate peroxocarboxylic acid is present in an amount of 2% to 20% by weight, based on the composition. 
   
   
       14 . The composition according to  claim 11 , wherein the particulate peroxocarboxylic acid is solid at room temperature. 
   
   
       15 . The composition according to  claim 11 , wherein the particulate peroxocarboxylic acid is coated. 
   
   
       16 . The composition according to  claim 14 , wherein the particulate peroxocarboxylic acid is coated. 
   
   
       17 . The composition according to  claim 12 , wherein the particulate peroxocarboxylic acid is solid at room temperature. 
   
   
       18 . The composition according to  claim 12 , wherein the particulate peroxocarboxylic acid is coated. 
   
   
       19 . The composition according to  claim 17 , wherein the particulate peroxocarboxylic acid is coated. 
   
   
       20 . The composition according to  claim 11 , wherein the particulate peroxocarboxylic acid comprises a phthalimidoperoxyalkanoic acid. 
   
   
       21 . The composition according to  claim 11 , wherein the particulate peroxocarboxylic acid comprises 6-phthalimidoperoxyhexanoic acid. 
   
   
       22 . The composition according to  claim 12 , wherein the particulate peroxocarboxylic acid comprises a phthalimidoperoxyalkanoic acid. 
   
   
       23 . The composition according to  claim 12 , wherein the particulate peroxocarboxylic acid comprises 6-phthalimidoperoxyhexanoic acid. 
   
   
       24 . The composition according to  claim 11 , wherein the magnesium sulfate is present in an amount of up to 30% by weight, based on the composition. 
   
   
       25 . The composition according to  claim 12 , wherein the magnesium sulfate is present in an amount of up to 30% by weight, based on the composition. 
   
   
       26 . The composition according to  claim 11 , wherein the magnesium sulfate is present in an amount of greater than 4% up to 20% by weight, based on the composition. 
   
   
       27 . The composition according to  claim 11 , wherein the surfactant is present in an amount of 0.1% by weight to 50% by weight, based on the composition. 
   
   
       28 . The composition according to  claim 11 , wherein the surfactant comprises a mixture of an anionic surfactant and a nonionic surfactant. 
   
   
       29 . The composition according to  claim 11 , wherein the composition has a pH value of 2 to 6. 
   
   
       30 . The composition according to  claim 11 , wherein the particulate peroxocarboxylic acid and a liquid phase of the composition have densities which differ from each other by no more than 10%.
