Definitions
- the present invention relates to a detergent composition for photoactivation bleaching and its method of use.
- bleaching is understood to mean the elimination of colored stains or stains resistant to the action of the alkaline aqueous medium and of the detergents present in the usual detergents. In addition to this bleaching action, bleaching also includes a disinfectant or antiseptic action in the detergent bath.
- bleaching is obtained in particular by the addition of perborate to the washing medium.
- the washing must be carried out at a temperature of 80 to 90 ° C.
- Sodium hypochlorite can also be used in a cold wash.
- such a product causes significant deterioration of the fibers.
- the object of the invention is therefore a bleaching system by photoactivation, which is simple to use, which is effective with respect to soiling while respecting the treated fiber as well as possible, and involving a sensitizer, adsorption on the fiber is completely reversible on rinsing.
- the detergent composition according to the invention is characterized in that it contains, as a bleaching system by photoactivation, at least one sensitizing agent consisting of a soluble salt or disel of an acid of general formula: in which the hydrogen atoms carried by carbons 1 to 8 may or may not be substituted, in particular by halogens; and an additive of the cyclic tertiary mono, di- or tetramine type.
- a product belonging to the family of xanthene dyes and more specifically of the fluorescein type is used. As indicated above, these products correspond to the water-soluble salts or disels of the acid of formula (1):
- the salts will generally be the sodium or potassium salts or disels.
- the hydrogen atoms carried by the carbons identified 1 to 8 can be substituted in particular by atoms of Cl, Br and I.
- the products which are particularly suitable for the composition of the invention are those which, corresponding to formula 1, have the property of being adsorbed on the fiber in a reversible manner.
- they have an absorption spectrum located substantially in the visible light range, that is to say between 400 and 800 nm, more precisely between 400 and 600 nm.
- M can be an alkali or alkaline earth metal.
- 1,2-dibromo fluorescein that is to say the dibromo salt or disel of formula 1, 3,4-dibromo fluorescein, ie phloxine tetrabromo-1,2,3,4 tetrachloro-5,6,7,8 fluorescein, diodo-1,2 fluoresceine, diodo-3,4 fluoresceine and tetraiodo-1,2,3,4 têtrachloro-5 , 6,7,8 fluorescein or "Rose Bengal”.
- 1,2-dibromo fluorescein that is to say the dibromo salt or disel of formula 1, 3,4-dibromo fluorescein, ie phloxine tetrabromo-1,2,3,4 tetrachloro-5,6,7,8 fluorescein, diodo-1,2 fluoresceine, diodo-3,4 fluoresceine and tetraiodo
- compositions comprising a combination of several sensitizing agents of the type described above.
- the bleaching system of the invention comprises an additive which, as indicated above, is chosen from the group of cyclic tertiary mono-, di- or tetramines.
- an additive which, as indicated above, is chosen from the group of cyclic tertiary mono-, di- or tetramines.
- amines of the above type are used but which are also bridged; by this is meant the amines in which a nitrogen atom is linked transversely to another nitrogen atom or to a carbon atom of the ring.
- DABCO 1,4 diaza bicyclo - (2,2,2) octane
- ABCO quinuclidine
- Another interesting additive is hexamethylenetetramine.
- Bleaching systems comprising products of the type defined above can be incorporated into a solid or liquid detergent composition.
- this detergent composition may include a surfactant. It is preferable that this surfactant is anionic or, if a mixture of surfactants is used that there is in this mixture at least one anionic surfactant. Mention may be made, for example, as anionic surfactants which can be used in the context of the invention, of the water-soluble salts of alkyl sulphate.
- composition may also include a base or "builder" of known type such as, for example, phosphates or polyphosphates of alkali metals soluble in water or else silicates.
- a base or "builder” of known type such as, for example, phosphates or polyphosphates of alkali metals soluble in water or else silicates.
- the composition may include any known additive of the arti-nousse type, anti-redepositing, perfumes for example.
- the proportions of the various constituents of the detergent composition will be chosen such that once the composition has dissolved in the detergent bath, the concentration of sensitizer and in particular of eosin is between approximately 10 -6 M and 10 -5 M. Preferably, this concentration should be located around 2.5 and 10.10 -6 M. For higher values, the sensitizer in too large a quantity can have an internal filtering effect which is detrimental to photoactivation during irradiation of the bath. detergent.
- the concentration of each sensitizer remains in the range fixed above.
- the additive concentration must be between 10 M and 10 -1 M. Below 10 -3 M there is no effect. Beyond 10 -1 M, there is no significant gain in money laundering. Preferably, this concentration is located around 10 -2 M.
- the constituents of the detergent composition will preferably be chosen so that the pH of the detergent bath is between 9 and 11.
- compositions of the invention can be used in an extremely simple manner.
- the textile to be treated is first immersed in a detergent bath containing the composition according to the invention.
- the textile is kept there with stirring at room temperature and in the dark or in ambient light to allow the deposition of the sensitizer.
- the detergent bath and the textile which is contained there are asleep to a light irradiation in the visible range (400 - 800nm) resulting for example from a halogen quartz lamp.
- This irradiation can last between 10 and 60 minutes, generally between 10 and 30 minutes. Generally during this irradiation, the temperature of the detergent bath is kept close to ambient.
- the bath is separated from the textile and the latter is then rinsed with water for a few minutes to remove the sensitizer.
- a washing bath comprising 3.1 g / l of builder, SDS: 0.1 M, eosin: 0.5.10 -5 M, DABCO: 10 -2 M, pH: 10.6.
- the dyed strips are finally dried with hot air, ironed between two sheets of filter paper and cut into test pieces.
- the specimens having a homogeneous dye are selected and stored in the dark.
- a sample of stained cotton fabric prepared in the above manner and of known reflectance is then introduced into the washing bath and kept under stirring, at room temperature and in the dark, to allow the deposition of eosin.
- the detergent bath containing the fabric is then irradiated.
- the light irradiation is ensured by a HEDLER projector type "DE LUXE 2000" equipped with a quartz - halogen lamp 1000 w (CSRAM - HALOGEN SUPERPHOT).
- the distance between the surface of the detergent bath and the lamp is approximately 30 cm.
- the irradiation lasts 60 min.
- the temperature of the detergent bath is maintained at around 25 ° C.
- the samples are rinsed for 1 hour in 600 ml of permuted water protected from light and then dried between those sheets of filter paper.
- Example 2 The procedure is the same as in Example 1 with a cotton fabric stained with wine (standard soiling EMPA 114).
- the irradiation lasts 30 minutes.
- a washing bath comprising 3.1 g / l of builder, SDS: 0, M, eosin: 0.8 10 -5 M, HMTA: 10 -2 M, p H: 9.8.
- the irradiation lasts 10 minutes.
- a washing bath comprising 3.1 g / l of builder, SDS: 0.1 M, respective concentration for each sensitizer: 10 -5 M, DABCO: 10 -2 M.
- the samples are prepared, washed and analyzed as described in Example 1. However, the irradiation is 20 minutes.
- a whitening effect greater or close to that obtained with a system with a single sensitizer (as in the case of Examples 2 or 3) is obtained for the same soiling with a shorter irradiation time.
- Example 2 The procedure is the same as in Example 1 on the same soiling (NESTEA).
- the sensitizer concentration is 10 -5 M.
- the irradiation is 30 minutes.
- the system of the invention provides a bleaching of the same order of magnitude, or even greater than that obtained with a perborate system, with a washing time less in some cases for the wine in particular, and in all cases at a much lower temperature.
