Definitions
- the present invention relates to laundry laundering using a peroxide compound.
- sodium perborate which is by far the most widely used peroxidized bleaching agent to date, is well known to be the source of pollution caused by the presence of boron in waste water.
- the process according to the invention like the compositions which take part in its realization and are another object of the invention, lead to whitening effects superior to those obtained by the peroxide compounds used to date, while avoiding the pollution due to the most used of them, sodium perborate, and the use of complex activators.
- the process according to the invention for bleaching laundry in a bath using a peroxide compound is characterized in that bleaching is carried out at a pH of between 10.5 and 12.5 in the presence, as a peroxide compound, of calcium peroxide CaO2 introduced in hydrated form or not so that the quantity of calcium per liter of bath is between 1.10 ⁇ 3 and 1.10 ⁇ 2 atom-gram.
- the bath may also contain, as is most often the case in practice, in kind and in quantity, all or part of the products designed to be usually present in a bath with detergent action, other than peroxidized bleaching agents, such as as surfactants and accompanying products: alkylbenzenesulfonates, alkylarylbenzenesulfonates, ethoxylated fatty alcohols, anti-redeposition agents, brighteners, perfumes, sequestering agents, alkaline phosphates, etc. .... Examples of known detergents are for example given by Marshall Sittig in DETERGENT MANUFACTURE , Noyes Data Corporation, 1976.
- the sequestering agents of the alkaline-earth ions are chosen for example from the alkaline salts of polyphosphoric acids such as sodium tripolyphosphate designated in the following by TPP, Na, the alkaline salts of acids polyaminecarboxylic or polyoxycarboxylic acids such as those of ethylenediaminetetraacetic acid, the pentasodium salt of diethylenetriaminepentaacetic acid, the trisodium salt of nitrilotriacetic acid, or even sodium citrate.
- polyphosphoric acids such as sodium tripolyphosphate designated in the following by TPP, Na
- the alkaline salts of acids polyaminecarboxylic or polyoxycarboxylic acids such as those of ethylenediaminetetraacetic acid, the pentasodium salt of diethylenetriaminepentaacetic acid, the trisodium salt of nitrilotriacetic acid, or even sodium citrate.
- TPP Na is well suited in the context of the invention.
- the bleaching effect is particularly improved by applying the method of the invention when the complexing agent of alkaline earth ions is brought into play in an amount at least equal to that allowing the sequestration of calcium ions in solution in the bath.
- a composition in accordance with the invention containing a peroxidized compound for laundry bleaching is characterized in that it contains, as peroxidized compound, calcium peroxide CaO2 in hydrated form or not in an amount such that it allows the formation of a bath which, at pH between 10.5 and 12.5 contains per liter of 1.10 ⁇ 3 to 1.10 ⁇ 2 gram atom of calcium in order to carry out the process described above.
- compositions may also comprise in nature and in quantity all or part of the products known to be usually present in a bath with detergent action, other than the peroxide bleaching compounds hitherto used, such as those mentioned above.
- It can thus comprise sequestering agents of alkaline earth ions, preferably in an amount at least equal to that corresponding to the sequestration of calcium ions in solution in the bath formed from it.
- Sodium tripolyphosphate is particularly suitable in a composition according to the invention as sequestering calcium ions.
- a composition of the invention allows the formation of the bleaching bath by simultaneous addition of its constituents.
- the formation of the bath can be carried out anyway by bringing its constituents into contact in any order.
- calcium peroxide in hydrated or non-hydrated form can be added to the other constituents, including the sequestering agent where appropriate, dissolved in water before this addition.
- the calcium peroxide used in hydrated form or not in carrying out the process or the composition of the invention can be prepared in any known manner. Examples of preparation are indicated for example in the NEW TREATY OF MINERAL CHEMISTRY, P. Pascal, volume IV, 1958, pp. 399-400 or in PEROXIDES, SUPEROXIDES, and OZONIDES of ALKALI and ALKALINE EARTH METALS, Il'ya Ivanovich Vol'nov, Plenum Press, New-York 1966, pp. 58-60.
- the bleaching operation according to the invention is followed by the rinsing and wringing operations before drying as they are conventionally practiced.
- the rate of temperature rise from the bath to the plateau temperature from the ambient temperature of approximately 20 ° C. is 10 ° C. per minute.
- the treated fabric is conventionally separated from the bath, drained and rinsed with water at room temperature before drying, - the pH of the bath is each between 10.5 and 12.5, - the degree of whiteness of the fabric is measured using a spectrophotometer Erichsen GLOSSMASTER No. 507 étallonné a whiteness equal to 90 for the provided magnesium oxide as a reference with the device, - the fabric to be treated has a measured degree of white equal to 41, - calcium peroxide has been used in the form of an octahydrate.
