Definitions
- the present invention relates to bleaching compositions, mainly for use in laundry applications.
- the compositions according to the present invention which comprise hydrogen peroxide as well as peracid precursors, are stable upon storage.
- hydrogen peroxide bleach activators have been developed and have been extensively described in the art. These activators are mainly transition metals or peracid precursors. Peracid precursors react with hydrogen peroxide to yield peracids. Peracids are the "activated" bleaching compounds which are efficient at low temperatures.
- a bleaching composition comprising hydrogen peroxide, an organic peracid precursor selected from a specific class, e.g. glycol and glycerin esters, and by formulating said composition in a narrow, acidic pH range.
- the mildly acidic pH range allows for adequate chemical stability of both the hydrogen peroxide and the organic peracid precursor.
- the activation of hydrogen peroxide trough the formation of a peracid is enhanced by the pH raise which occurs upon dilution in the wash water, especially when a detergent composition bringing further alkalinity is also present in the wash water.
- Glycol esters have been often described as solvents in detergent and bleaching compositions. Such compositions are described for instance in US-A-3 956 159. These compositions have a pH of 6.5 and above.
- JP-A-62252500 discloses bleaching compositions which comprise a bleach activator, including triacetin. These compositions are formulated at neutral or weakly basic pH.
- Bleaching compositions for various applications comprising triacetin are also disclosed in JP-A-62001792, JP-A-62001794 JP-A-62001796, and JP-A-61042600 (abstracts).
- EP-A-125 781 discloses bleaching compositions comprising hydrogen peroxide and a particular peroxyacid generator like for example 1,1,5-triacetoxypent-4-ene, 1,1,5,5-tetraacetoxy pentane, the corresponding butene and butane compounds, ethylidene benzoate acetate and bis (ethylidene acetate) adipate.
- a particular peroxyacid generator like for example 1,1,5-triacetoxypent-4-ene, 1,1,5,5-tetraacetoxy pentane, the corresponding butene and butane compounds, ethylidene benzoate acetate and bis (ethylidene acetate) adipate.
- compositions according to the present invention are clear aqueous bleaching compositions comprising hydrogen peroxide as well as an organic peracid precursor, characterized in that the compositions have a pH in the range of from 3.5 to 6, and that the organic peracid precursor is a compound according to the formula: wherein x is 0 or 1, R 1 , R 2 , R 3 are independently selected from -H, -OH, where R 4 is C 1 -C 4 alkyl, with the proviso that at least two of R 1 , R 2 or R 3 are or mixtures thereof.
- compositions according to the present invention are clear aqueous liquid compositions which comprise hydrogen peroxide.
- the compositions according to the present invention comprise from 0.5 % to 20 % by weight of the total composition of hydrogen peroxide, more preferably from 2 % to 15 %, most preferably from 4 % to 9%.
- compositions according to the present invention further comprise a specific organic peracid precursor according to the formula: wherein x is 0 or 1, R 1 , R 2 , R 3 are independently selected from -H, -OH, where R 4 is C 1 -C 4 alkyl, with the proviso that at least two of R 1 R 2 or R 3 are or mixtures thereof. All these compounds are well known chemicals which are commercially available or can be synthesized according to the chemical literature.
- Preferred such peracid precursors for use in the compositions according to the present invention are selected from ethylene glycol diesters, triacetin and diacetin, or mixtures thereof. Particularly preferred compounds are triacetin and ethylene glycol diacetate. Tributyrin also displays excellent stability in the compositions according to the present invention but is less preferred because it is less soluble in the compositions according to the present invention.
- compositions according to the present invention typically comprise from 1 % to 15 % by weight of the total composition of such an organic peracid precursor, or mixtures thereof.
- the desired amount of organic peracid precursor can also be defined in relation to the amount of hydrogen peroxide in the composition. Accordingly, the compositions according to the present invention preferably comprise from 0.1 to 2 moles of organic peracid precursor per mole of hydrogen peroxide.
- compositions according to the present invention have a pH in the range of from 3.5 to 6, most preferably from 3.5 to 5, most preferably about 4.
- the pH of the composition can be adjusted and buffered with such chemicals as organic and inorganic acids which are stable to oxidation, citric acid, sulphuric acid, sodium hydroxide, ammonia and amines.
- Preferred buffer for use in the compositions according to the present invention is citric acid. It is essential that the pH of the composition remains within the above range as said range is critical to ensure adequate chemical stability of the hydrogen peroxide and of the specific organic peracid precursors used in the compositions according to the present invention.
- compositions according to the present invention may comprise surfactants.
- Preferred surfactants for use herein are well known anionic surfactants such as alkyl benzene sulphonates and alkyl sulfates, and/or nonionic surfactants such as ethoxylated and/or propoxylated alcohols. All surfactants for use herein must be resistant to oxidation by peracids and hydrogen peroxide, and are preferably water-soluble.
- the compositions according to the present invention can comprise from 0% to 30% by weight of the total composition of surfactants, preferably from 0.5 % to 15 %, most preferably from 2 % to 8 %.
- compositions according to the present invention may further comprise peroxide stabilizers such as stannates, 8-hydroxyquinoline, pyrophosphates and phosphonates.
- Chelating agents may also be useful in the context of the present invention; suitable chelants include EDTA, NTA and DETPA, picolinic and dipicolinic acids and amino polyphosphonates, although some of these are poorly environmentally compatible.
- Radical scavengers can also be used herein, such as butylated hydroxy toluene and other hindered hydroxy benzenes, or sodium benzoate. Butylated hydroxy toluene is a highly preferred ingredient as it has been observed that it stabilizes the peracid precursors according to the present invention, as well as hydrogen peroxide.
- compositions according to the present invention can also comprise such optional ingredients as whitening agents, dyes, builders, thickeners, hydrotropes, perfumes, all of which need to be compatible with the mildly acidic pH and the oxidizing environment of the compositions according to the present invention.
- compositions according to the present invention are further illustrated in the following examples.
- compositions are made by mixing together the listed ingredients in the listed proportions.
