Definitions
- the present invention relates to aqueous alkaline peroxygen bleach-containing compositions, and more particularly, to stabilised and buffered compositions.
- Aqueous household detergent compositions have, for many years, employed bleaches for the purpose of bleaching and/or disinfecting hard-surfaces and/or fabrics.
- Hypochlorite bleaches have been used most extensively for this purpose because they are highly effective and inexpensive.
- a drawback associated with hypochlorite bleaches is that they are perceived by the consumer as being not fully satisfactory regarding their safety profile.
- Aqueous compositions comprising a peroxygen bleach have generally been less utilised in the household market, although they deliver effective bleaching performance and/or disinfecting performance, and they are perceived by the consumer as being less harsh than compositions based on hypochlorite.
- hydrogen peroxide is generally perceived to be environmentally acceptable as its decomposition products are oxygen and water. It is believed that this lack of use in the household is partially attributable to the instability of aqueous peroxygen bleach-containing compositions. This instability is particularly noticeable in alkaline medium where it is mediated principally by contamination of metal ion occurring in the composition itself and/or in the wash solution obtained after having diluted the composition with water.
- aqueous peroxygen bleach-containing compositions provide effective bleaching and/or disinfecting, they do not effectively remove greasy stains. Thus, there is still some room to further improve the greasy stain removal performance of liquid aqueous peroxygen bleach based compositions.
- liquid aqueous alkaline compositions having a pH above 8 comprising a peroxygen bleach, a radical scavenger, a chelating agent and a pH buffer.
- a chelating agent preferably a phosphonate/amino phosphonate chelating agent, a radical scavenger, preferably di-tert-butyl hydroxy toluene (BHT) and/or butyl hydroxyanisol (BHA), and a pH buffer, preferably a borate pH buffer, in an alkaline aqueous peroxygen bleach-containing composition, maintains both the pH and the peroxygen bleach stability upon prolonged storage periods.
- a radical scavenger preferably di-tert-butyl hydroxy toluene (BHT) and/or butyl hydroxyanisol (BHA)
- BHT di-tert-butyl hydroxy toluene
- BHA butyl hydroxyanisol

Indeed, when using the compositions according to the present invention in a laundry application fabric damage and/or color damage is reduced as compared to the same compositions without said cheating agent and/or radical scavenger.
