Abstract

Abstract 57 The disclosure relates to the use as pourable bleaching compositions of aqueous suspensions of peroxycarboxylic acids, said suspensions also containing an alkali metal salt of an alkyl benzene sulphonic acid. The compositions are chemically and physically stable. Their physical stability can be enhanced by the addition of sodium sulphate or potassium sulphate. They are protected from hazards due to spilling and drying up. Also disclosed are the above bleaching compositions in the packaged form.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 43 words
Use as pourable bleaching composition of a suspension in water comprising a peroxycarboxylic acid derived from a dicarboxylic acid containing 8 to 13 carbon atoms, characterized in that the bleaching composition also comprises an alkali metal salt of an alkyl benzene sulphonic acid.
Claim 2
Dependent Claim 43 words
Use as pourable bleaching composition of a suspension in water comprising a peroxycarboxylic acid derived from a dicarboxylic acid containing 8 to 13 carbon atoms, characterized in that the bleaching composition also comprises an alkali metal salt of an alkyl benzene sulphonic acid.
Claim 3
Dependent Claim 28 words
Use according to claim 1, characterized in that the alkyl group of the alkali metal salt of an alkyl benzene sulphonic acid contains 9 to 15 carbon atoms.
Claim 4
Dependent Claim 23 words
Use according to claim 1, characterized in that the alkali metal salt of an alkyl benzene sulphonic acid is sodium dodecyl benzene sulphonate.
Claim 5
Dependent Claim 37 words
Use according to claim 1, characterized in that the alkali metal salt of an alkyl benzene sulphonic acid is used in an amount of 0,5 to 15% by weight, calculated on the weight of the bleaching composition.
Claim 6
Dependent Claim 21 words
Use according to claim 1, characterized in that the bleaching composition also comprises sodium sulphate, potassium sulphate or a mixture thereof.
Claim 7
Dependent Claim 35 words
Use according to claim 5, characterized in that the sodium sulphate, potassium sulphate or mixture thereof is used in an amount of 0,01 to 20% by weight, calculated on the weight of the bleaching composition.
Claim 8
Dependent Claim 76 words
A pourable, aqueous bleaching composition comprising a suspended peroxycarboxylic acid derived from a dicarboxylic acid containing 8 to 13 carbon atoms, characterized in that the bleaching composition also comprises an alkali metal salt of an alkyl benzene sulphonic acid in an amount of 0,5 to 15% by weight and sodium sulphate, potassium sulphate or a mixture thereof in an amount of 0,01 to 20% by weight, said amounts being calculated on the weight of the composition.
Claim 9
Dependent Claim 76 words
A pourable, aqueous bleaching composition comprising a suspended peroxycarboxylic acid derived from a dicarboxylic acid containing 8 to 13 carbon atoms, characterized in that the bleaching composition also comprises an alkali metal salt of an alkyl benzene sulphonic acid in an amount of 0,5 to 15% by weight and sodium sulphate, potassium sulphate or a mixture thereof in an amount of 0,01 to 20% by weight, said amounts being calculated on the weight of the composition.
Claim 10
Dependent Claim 39 words
A pourable, aqueous bleaching composition according to claim 7, characterized in that the peroxycarboxylic acid is 1,12-diperoxydodecanedioic acid and the alkyl group of the alkali metal salt of an alkyl benzene sulphonic acid contains 9 to 15 carbon atoms.
Claim 11
Dependent Claim 19 words
A packaged bleaching composition, the bleaching composition being of the type described in any one of the preceding claims
