Definitions
- peroxycarboxylic acid-containing suspensions as bleaching compositions, novel bleaching compositions and bleaching compositions in the packaged form
- the invention relates to the 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.
- liquid bleaching compositions over solid bleaching compositions are that in their preparation there is no need for cost- increasing shaping steps, such as drying and granulating, and the fabrics to be treated are rapidly and evenly bleached, so that high concentrations of the bleaching agent in places can be satisfactorily avoided.
- the present bleaching composition does not show this drawback.
- the invention relates to the use of the above type, characterized in that the bleaching composition also comprises an alkali metal salt of an alkyl benzene sulphonic acid.
- An additional advantage to the present composition is that, provided that the proportions of the constituents to be used are properly chosen, it is protected from hazards due to spilling and drying up, as a result of which solid peroxide particles are formed.
- solid peroxide particles Of peroxides in the solid state it is known that they are exposed to explosion, shock and abrasion hazards.
- solid peroxide particles will form that are provided with a coating such that they are desensitized.
- the pourable compositions disclosed in GB 1 535 8 ⁇ 4 are not protected in that way, the amount of thickening agent required for these compositions being so small that in the event of spilling and drying up solid particles are formed that are insufficiently desensitized. From experiments it has moreover been found that this drawback cannot be eliminated by the addition to these suspensions of well-known desensitizing agents such as sodium sulphate, because the properties of these suspensions will be even further deteriorated then.
- composition according to the invention is physically stable, i.e. after storage for 6 weeks at 20°C the peroxycarboxylic acid is well dispersed and the suspension does not display any phase-separation. If precipitation takes place at all, the homogeneity of the dispersion can be readily restored by gently shaking it.
- composition according to the invention is chemically stable, i.e. after storage for 2 weeks at 40°C it still has the same or practically the same active oxygen content.
- composition according to the invention is pourable, by which is to be understood that at 20°C the composition has a viscosity between 1 and 1200 mPa.s, preferably between 50 and 500 mPa.s (Brookfield rotational viscometer [RV type], 20 rpm).
- the invention also relates to those bleaching compositions that are new as such and to the present bleaching compositions in the packaged form.
- the bleaching component in the present composition consists of a peroxycarboxylic acid derived from a dicarboxylic acid containing 8 to 13 carbon atoms.
- Such peroxycarboxylic acids are not, or hardly soluble in water (solubility less than 1% by weight in water at 20°C).
- the present composition should contain diperoxy dicarboxylic acids, such as 1,12-diperoxydodecanedioic acid, 1,13-diperoxy- tridecanedioic acid or suitable mixtures thereof.
- the composition according to the invention contains peroxycarboxylic acid in an amount such that the active oxygen content of the composition is between 0,1 and 4%, preferably between 0,1 and 3%.
- the present composition must contain an alkali metal salt of an alkyl benzene sulphonic acid.
- the alkyl group may be branched or linear and contains 9 to 22 carbon atoms, preferably 9 to 15 carbon atoms, more particularly 11 to 13 carbon atoms.
- these alkyl benzene sulphonates may be mentioned sodium undecyl benzene sulphonate, sodium dodecyl benzene sulphonate and sodium tridecyl benzene sulphonate. Also mixtures of these sulphonates may be used.
- composition according to the invention should contain sodium dodecyl benzene sulphonate.
- the alkali metal salt of an alkyl benzene sulphonic acid should be used in an amount such that the composition is pourable and physically stable.
- the composition will contain alkali metal salt of an alkyl benzene sulphonic acid in an amount of 0,5 to 15% by weight, and preferably 2 to 10% by weight, calculated on the weight of the composition. Use of amounts less than 0,5% by weight will result in compositions that have insufficient physical stability; use of amounts higher than 15% by weight will result in obtaining viscous compositions that are no longer pourable.
- the alkali metal salts of alkyl benzene sulphonic acids commonly used in actual practice as emulsifier are so-called technical products in which as impurity an inorganic salt such as sodium sulphate is contained.
- these technical products can very well be used for preparing the present compositions, a preferred embodiment consists in that also particular inorganic salts are added. It has been found that adding sodium sulphate, potassium sulphate or mixtures thereof has a favourable effect on the physical stability of the compositions, i.e. if there appears to be any precipitation at all upon using a technical emulsifier alone, it can entirely be stopped by the additional use of said inorganic salts.
- compositions with the same properties can be prepared that contain less emulsifier than when no use is made of these inorganic salts.
- This last- mentioned embodiment is preferred in actual practice because of the considerably lower cost price of the inorganic salts as compared with that of the emulsifier to be used.
- a preferred inorganic salt is sodium sulphate.
- the amount of inorganic salt to be used will partly be dependent on the amount of inorganic salt originating from the emulsifier as impurity and should be such that the bleaching composition is pourable and physically stable.
- the bleaching composition according to the invention will contain inorganic salt, including the inorganic salt originating from the emulsifier, in an amount of 0,01 to 20% by weight, preferably 2 to 10% by weight, calculated on the weight of the composition.
- composition according to the invention may still contain other additives, as examples of which may be mentioned:
- the present bleaching compositions may very effectively be used in the pre-bleaching treatment of dirty washing at low temperature (say, about 30°C).
- the treatment of dirty washing with the usually applied heavy and light duty detergents they are also very suitable to be separately added to the wash liquor. Their effect is at least equivalent to that of the bleaching compositions disclosed in GB 1 535 804.
- compositions according to the invention may be prepared by adding the peroxycarboxylic acid, with stirring, to an acidified mixture (preferably pH 3,5-4,5) of water, alkyl benzene sulphonate and any other additives.
- the peroxycarboxylic acid may be used in the form of powder (primary particle size 1-100 microns) or in the form of wet filter cake, as obtained after the peroxycarboxylic acid preparation from the corresponding dicarboxylic acid and hydrogen peroxide.
- the pH of the composition is finally set to a particularly desired value, which should be in the acid range, use being made of, for instance, aqueous sodium hydroxide or hydrochloric acid. It is preferred that the pH should not be higher than 5.
- compositions as mentioned in Table 1 were prepared. Compositions 1-6 are according to the invention. The pH values of these compositions were in the range of 3,5 to 4,5.Composition 7 is according to GB 1 535 804.
- compositions 1,2,4,5, and 6 did not display any phase-separation or precipitation phenomena.
- sample of composition 3 had precipitated, no thick bottom layer had formed and the original homogeneity of the dispersion could be restored by gentle shaking.
- sample of composition 7 had precipitated and a thick bottom layer had formed (phase-separated) which could not very well be re-dispersed.
- compositions 2,3 and 7 were evaporated to dryness by means of an air stream at 25° - 30°C, after which the material thus obtained was subjected to a Pressure Vessel Test.
- This test is described in Vervoer Gevaarlijke stoffen, 23 December 1980, Aanhangsel Al bij bijlage A, pp. 907,908, 915: Wunschsuitgeverij.
- 10 grammes of the material to be tested are heated by a standardized gas flame in a pressure vessel fitted with a bursting disk set to 6 bar.
- a blow-off opening with variable diameter.
- the test procedure implies that such a blow-off opening is found that after decomposition (explosion, combustion) of the peroxide, the bursting disk is still just intact.
- the admissible opening (in mm) is given as PVT value.
- the PVT values found for the material from composition 2 were less than 1 mm, from composition 3 less than 1 mm, and from composition 7 they were 6 mm. (The PVT value for pure diperoxydodecanedioic acid is 7 mm).
- Suspensions were prepared from diperoxydodecanedioic acid (11,65 g of wet filter cake with an active oxygen content of 5,1%), hydroxyethylidene diphosphonic acid (Dequest 2010 * ; 0,25 g), emulsifier and water; the pH of the suspensions was 3,9-4,1.
- suspension 1 is not a composition according to the invention; it contains about 30% of emulsifier and has a viscosity of 1975 mPa.s. It has been found that the effect of emulsifiers on the chemical stability of peroxycarboxylic acid compositions can very well be established when they are used in relatively high concentrations.
