- Liquid detergent compositions may be prepared by admixing the essential and optional ingredients in any desired order to provide compositions containing the ingredients in the the requisite concentrations.
- the colour benefit associated with the compositions of the invention is twofold: protection (maintenance) of the colour or whiteness of new fabrics, and restoration
- New fabrics when washed with the compositions of the invention, show reduced colour degradation as compared with fabrics washed in control formulations without IDS.
- the fabrics maintain a new appearance even after multiple washing. This protection or maintenance benefit has been found to apply both to white and to coloured fabrics.
- a cause of the colour degradation resulting from the laundry process may be heavy metal ions, especially iron but also copper, zinc and manganese: these may originate from the water or water pipes, from washing machine parts, from the detergent composition used, or from the soil present on the fabric.
- the colour care benefit obtained according to the present invention may be attributed to the sequestration by the IDS of any heavy metal ions present in the wash liquor.
- IDS should be especially effective in this regard.
- IDS should be significantly more effective that the more common detergent and highly effective sequestrant, nitrilotriacetate (NTA) .
- the composition has a 0.25% aqueous solution pH (in demineralised water at 30°C) not exceeding 10.5, preferably not exceeding 10.0.
- the preferred pH range is from 8.0 to 10.5, more preferably from 8.5 to 10.0.
- a further subject of the invention is a process in which white or coloured fabrics are laundered using the composition of the invention.
- the process is carried out in a wash liquor having a pH not exceeding 10.5, more preferably not exceeding 10.0.
- the two preferred conditions previously mentioned - very low pH, and low sequestrant level - have especial relevance to the handwash as carried out, for example, in South East Asia. In that region, it is a common habit to presoak or prerinse the fabrics in water, without detergent, to remove gross soiling.
- the wash liquor pH may be as low as 6.0 to 7.0.
- the wet fabrics are then immersed in the main wash liquor (detergent solution) .
- the additional water imported into the wash liquor from the wet fabrics has the dual effect of diluting the wash liquor (and thus lowering the sequestrant level) and lowering the pH.
- IDS has also been found to reduce the fading upon laundering of chlorine-sensitive dyes. This fading occurs due to the presence of sodium hypochlorite, which is routinely put into supply water for hygiene purposes: levels of 0.5 ppm are typical. This causes fading of dyes of a wide range of colours .
- the incorporation of IDS in accordance with the present invention can significantly reduce the amount of fading attributable to chlorine in the wash water. The stain removal benefit
- the sequestrants used were as follows:
- IDS iminodisuccinate, tetrasodium salt, ex Bayer
- EDTMP ethylenediaminetetramethylene phosphonate, calcium salt (Dequest (Trade Mark) 2047 ex Monsanto)
- EDDS ethylenediamine disuccinate, tetrasodium salt
- Magnesium silicate Macrosorb (Trade Mark) MS33 ex Crosfield Chemicals, UK.
- the fabrics were washed in demineralised water containing copper ions (0.5 ppm Cu 2+ ex CuCl 2 ) at a liquor to cloth ratio of 200:1 in tergotometers for 30 minutes at 30°C at 90 rpm. Experiments were carried out at two different pH values, 9.5 and 6.5, the pH adjustment being made by adding sodium hydroxide (the addition of the copper salt having caused a slight drop in pH) .
- Colour changes were monitored as reflectances differences at 620 nm. Two different effects are in operation here: dye fading, which leads to a generally small reflectance increase; and dye darkening (colour degradation) resulting from the presence of the copper ions, leading to a rather larger reflectance decrease. Both effects are undesirable and result in deterioration of the appearance of the fabric.
- the reflectance difference observed should be close to zero or a small increase (not greater than 3 units, and preferably not greater than 2 units) . The results were as shown in the Table below.
- Example 1 The procedure of Example 1 was repeated at pH 6.5 using white cotton fabrics and a "cocktail" of heavy metal ions:
- a detergent powder formulation was prepared by conventional spray-drying and postdosing techniques to the following formulation:
- the fabrics were washed five times in a wash liquor comprising 20/6° FH (Ca/Mg) water containing a "cocktail" of heavy metal ions and 2.5 g/litre of the detergent composition, and with the pH adjusted to 9.5 using dilute sulphuric acid.
- the washes were carried out in tergotometers at a liquor to cloth ratio of 200:1 for 30 minutes at 30°C and 90 rpm. After each wash, two rinses were carried out at a liquor to cloth ratio of 200:1 and the fabrics were line dried.
- Example 3 The procedure of Example 3 was repeated using the same powder formulation but the pH was adjusted to the lower value of 8.5, and a total of 10 washes per example were carried out. Reflectances were measured after 5 and 10 washes .
- the sequestrants used were IDS (invention) and NTA (comparative) , at a level of 1.25 wt%.
- a detergent powder composition was prepared by conventional spray-drying and postdosing techniques to the following formulation:
- Rubbing time 30 seconds per piece. Wash temperature: 30 °C . Total washload weight: 1 kg.
- the coloured monitors were lme-dried m the shade.
- the fabrics used were cotton dyed with Direct Red 80. They were pre-treated with demineralised water containing 0.5 ppm Cu 2+ ions and having the pH adjusted to 6.5 by means of sodium hydroxide. The pretreatment was carried out using tergotometers at 30°C, 90 rpm and a liquor to cloth ratio of 200:1, then the fabrics were line dried.
- the fabrics were then washed in a wash liquor containing 2.5 g/1 of the detergent composition used in Example 3, and 0.5 ppm Cu 2+ , in 20/6° Ca/Mg French hard water) : the pH was adjusted from 9.9 to 9.5 using dilute sulphuric acid.
- the washes were carried out in tergotometers at 30°C, 90 rpm and a liquor to cloth ratio of 200:1.
- the washes were followed by two rinses in 20/6° Ca/Mg French hard water containing 0.05 ppm Cu 2+ at a liquor to cloth ratio of 200:1, and the fabrics were then line dried.
- the sequestrants, where present, were dosed directly into the wash liquor in the amounts indicated in the table below (percentages based on the detergent composition) .
- Example 6 The procedure of Example 6 was repeated at a 200:1 liquor to cloth ratio using both IDS and HIDS, and gave similar results :
- Example 6 The procedure of Example 6 was repeated using, instead of copper ions alone, the "cocktails" of heavy metal ions (different for wash and for rinse) used in Example 3. For the pretreatment step the same "cocktail" was used as for the wash.
- Example 6 The procedure of Example 6 was repeated using six different formulations of varying pH.
- the tergotometer method of previous examples was used.
- the initial pH was adjusted slightly downwards, using dilute sulphuric acid, to mimic the effect of soil on wash pH.
- Example 6 The washing and rinsing regime was as described in Example 6, and colour changes were monitored as reflectance changes ( ⁇ R) at 620 nm.
- Example 3 A multi-wash tergotometer experiment was carried out using the detergent composition of Example 3, without sequestrant (Comparative Example EE) or containing 1 wt% of IDS (Example 17) .
- the colour care benefit was determined using a range of coloured cotton monitors .
- the wash conditions were as follows
- Liquor to cloth ratio in the wash and rinse 200 to 1
- Wash temperature 40 °C .
- the washed fabrics were line-dried in the shade
- the wash conditions were as follows:
- Total load weight ca. 700 g.
- the washed fabrics were line-dried in the shade.
- Example 3 Stain removal was also assessed using a tergotometer method, and the formulation of Example 3. Comparative Example HH contained no sequestrant, while Example 3 contained 1 wt% of IDS.
- the washed fabrics were line-dried in the shade.
- Stain removal results are shown below. These are a measure of the stain removed so the larger the figure, the better the result . The improvement here was statistically significant and visually apparent .
- Phosphate-built and zeolite-built detergent powder formulations of high bulk density (850-900 g/1) containing IDS were prepared to the following formulations:
- Liquid detergent compositions containing IDS Liquid detergent compositions containing IDS
- Liquid detergent compositions were prepared to the following formulations :
- a liquiid detergent composition containing a lower level of IDS was prepared to the following formulation.
