Definitions

  • the present invention relates to a cleaning composition for providing effective stain removal.
  • Peroxygen bleach compounds are well known for their ability to remove stains from substrates. Such bleaching agents include hydrogen peroxide, or substances that can generate perhydroxyl radical, such as inorganic or organic peroxides. Generally, the peroxygen bleach compound or hydrogen peroxide must be activated.
  • One method of activation is to employ wash temperatures greater than 60 °C. High temperatures required for activation of the peroxygen bleach compound often damage the fabric dyes, and can also cause premature damage to the substrate or fabric.
  • Another known approach of activation is the use of organic precursor compounds along with peroxygen bleach compound. Addition of the organic precursors, often also referred to as bleach activators, into compositions having peroxygen bleach compound improves bleaching activity at lower wash temperatures, e.g. 40 to 60 °C. Examples of bleach activators are tetraacetylethylenediamine (TAED) and sodium nonanoyloxybenzenesulphonate(NOBS).
  • TAED tetraacetylethylenediamine
  • NOBS sodium nonanoyloxybenzenesulphonate
  • the bleach activators react with the perhydroxide anion (OOH-) of the hydrogen peroxide released by the peroxygen bleach compound in the aqueous solution to form a peroxyacid which is more reactive as a bleaching agent than the peroxide bleach alone.
  • a hydrophobic bleach activator used with the peroxygen bleach compound is effective on hydrophobic bleachable stains, such as burnt fat (like butter), tomato-sauce, cosmetics (like lipstick), but have limited performance on hydrophilic bleachable stains, such as tea or red wine stains.
  • a hydrophilic bleach activator when used with peroxygen bleach compound is effective on hydrophilic bleachable stains, but shows limited performance on hydrophobic bleachable stains.
  • Two or more bleach activators are often used together to activate peroxygen bleach compounds in order to make the bleach composition effective towards hydrophilic as well as hydrophobic stains.
  • WO11117617A1 discloses a cleaning composition having a dispersion of a particle in acidic aqueous phase for providing stability before use and performance in use.

  • SRI 100 ⁇ ⁇ E * aw
  • a SRI of 100 means complete removal of a stain. The higher the SRI value, the greater is the stain removal potential.
  • the clean (or virgin) fabric is an "absolute standard" which is not washed. For each experiment, it refers to an identical piece of fabric to that to which the stain is applied. Therefore, its point in L a b colour space stays constant.
  • Control A control detergent composition (Control) was prepared with a ratio between first bleach activator (TAED) to second bleach activator (DOBA) of 1:1. Control composition was formulated with no enzymes. Other standard laundry detergents were also included. The composition of Control is provided in Table 1.
  • Preferred detergent composition Ex 1 and Ex 2 had a ratio between first bleach activator (TAED) to second bleach activator (DOBA) of 1:1.
  • Ex 1 was formulated with a combination of protease and amylase.
  • Ex 2 was formulated with a combination of protease and lipase.
  • the composition of preferred detergent compositions is provided in Table 1.
  • Said machine wash protocol is as follows:
  • the delta SRI value after wash was determined as the difference between the absolute SRI value for a stained cotton swatch washed with the preferred composition and absolute SRI value for a stained cotton swatch washed with the control composition.
  • Delta SRI absolute SRI of stained cotton swatch washed with preferred composition ⁇ absolute SRI of stained cotton swatch washed with control composition
  • a delta SRI value higher than the LSD (Least significant difference) value indicates a statistically significant difference between the absolute SRI values of stained swatch washed with the preferred composition and the absolute SRI value of stained swatch washed with control composition.
  • the preferred granular detergent composition Comp 3 was prepared with a ratio between first bleach activator (TAED) to second bleach activator (DOBA) of 1:1 and having the enzymes protease, amylase and lipase. Other standard laundry detergents were also included.
  • the formulation of Comp 3 is provided in Table 3.
  • Table 4 clearly shows that the preferred composition (Comp 3) having a combination of bleach activators TAED, DOBA and enzymes protease, lipase and amylase shows statistically significant improvement in removal of sebum stain when compared to the commercially available comparative composition (ArielTM Actilift UK ).
