  • Foam is a normal side effect of machine washing while using detergents. However, generated foam during product usage sometimes perceived as the failure of the product as in the case of products in which the rinsing step is not desired. Also, foam has to disappear to provide a signal of good rinse ability.
  • Foam is crucial to the quality of a laundry wash. In moderation, it protects the laundry. But too much of it can impair the product performance by interfering with the mechanical agitation or contact of the surfactant solution with the soiled wash load. Additionally, too much foam also affects the machine's performance and the washing process itself and, what is more, increases water consumption. Reducing or impairing formation of foam amount can be achieved by using low foaming surfactants which is not compatible with the expected functional performance or using antifoam agents which are able to reduce foam during the product usage.
  • Antifoam additives are usually surface active compounds weakly soluble in the foaming surfactant solution. They can be derived from various natural fats and oils, petroleum derivatives or silicone oils. Antifoams can be roughly classified into two groups as surface-active materials and hydrophobic antifoams wherein antifoams based on surface active materials lead to foam breakage by acting at the air-liquid interface in the foam. They replace the surfactants to be able to form stable foam film and build a different type of filmless efficient in foaming.

  • Si-based foam suppressors are affecting transparency negatively compared to surfactant based foam suppressors. Therefore, they are not used in the present invention composition.
  • Builders have multiple anionic functional groups which are capable to bind by complexation earth alkaline metal cations.
  • First commercially used builders were polyphosphates which are still in use. They were able to capture multivalent metal cations and remove it from the medium by precipitating, since phosphate salts of these metal cations are less soluble in water.
  • Builders are incorporated into cleaning compositions in order to soften the water, boost the detergency effect, inhibit the redeposition and achieve a suspension of the soil during washing process. Additionally, they are expected to contribute the notable cleaning performance by providing alkalinity necessary for washing process, by improving the adsorption capacity and thus in turn effectiveness of surfactants.
  • Builders are added to the detergent composition primarily to complex with Ca 2+ and Mg 2+ and thereby reduce hardness of water. If these metal ions are captured, they are precipitated on fabrics that lead to graying of the fabrics.

  • the detergent amount used in the washing programme was 65.0 imL
  • the fabric load is 3.0 kg for each washing.
  • the main wash cycle was performed at 40°C.
  • the washed items were then hanged and dried at room temperature. The evaluations are reported as an average of calculation after twenty washings.
  • compositions For visual evaluation of transparency of the present invention compositions, the liquid compositions are visually examined for the presence of sediments and suspended matter under the light. Samples which are clear having full transmittance of light and showing no sediments are called as transparent. Samples showing sediments or do not allow transmittance of light due to the presence of suspended matter are called non-transparent.
  • Anti-Grayinq Performance Comparative Washing Results of Example 1-3 Compositions for Anti-Graying Performance
  • Anti-graying performances of example 1-3 compositions are determined spectrophotometrically by using WFK 10991 Graying Swatches as soil. Different types of fabric in the presence of WFK 10991 Graying Swatches were washed. The evaluations are reported as an average of two fabrics. Washings were performed five times and after the fifth washing, the fabrics were value analyzed. The test results are demonstrated in table 2.
  • Example 3 Spectrophotometric Evaluation Results of Example 1-3 Compositions for Anti-Graying Performance Reference Example 1
  • Example 2 Example 3
  • Example 1 composition represents better anti-graying effect than example 2 compositions which can be attributed that example 1 composition contains higher amount of anti-redeposition agent and enzyme mixture.
  • Example 2 composition has lower anti-graying effect due to the presence of low amount of anti-redeposition agent and enzyme mixture especially cellulose. Additionally, the presence of Si-based foam suppressor renders the example 2 composition non-transparent. The use of higher amount of anti-redeposition agent prevents redeposition of soil onto the surface of the fabric better so that this reduces the dulling or graying of the fabrics.
  • example 3 composition the results of example 1 and 3 compositions are quite close to each other with regard to ant-graying effect since the amount of anti-redeposition agent and enzyme mixture are same.
  • example 3 composition is not transparent which is taught to be due to the low amount of alpha olefin sulfonate.
  • Color Protection Performance Comparative Washing Results of Example 1-3 Compositions for Color Protection Performance
  • Color protection performances of example 1-3 compositions are determined spectrophotometrically. The evaluations are reported as an average of four fabrics. Different types of fabrics having different colors were washed twenty times and after the twentieth washing, the fabrics were value analyzed. The test results are demonstrated in table 3.
  • Example 3 Spectrophotometric Evaluation Results of Example 1-3 Compositions for Color Protection Performance Example 1
  • Example 2 Example 3
  • Example 1 composition provides better color protection effect even after 20 th wash than example 2 composition.
  • This effect of example 1 composition can be attributed to its composition having higher amount of anti-redeposition agent and enzyme mixture.
  • Example 2 composition has lower anti-graying effect due to the presence of low amount of anti-redeposition agent and enzyme mixture especially cellulose.
  • the use of higher amount of anti- redeposition agent prevents redeposition of soil onto the surface of the fabric better so that this reduces the dulling or graying of the fabrics. Therefore, the colors of the fabrics can be protected better and fabrics keep their color even after multiple washings.
  • example 1 and 2 compositions represent close results but example 2 composition is not transparent which is taught to be due to the presence of Si-based foam supressor.
  • example 3 The color protection ability of example 3 is as good as example 1 composition because both compositions contain similar amount of anti-redeposition agent and enzyme mixture. On the other hand, the example 3 composition is not transparent which is taught to be due to the low amount of alpha olefin sulfonate.
  • Whiteness performance of example 1 is determined spectrophotometrically. The evaluations are reported as an average of four fabrics which were washed twenty times and after the twentieth washing, the fabrics were analyzed. The test results are demonstrated in table 4. Table 4: Spectrophotometric Evaluation Results of Example 1 Composition for Whiteness Performance
  • Spectrophotometric evaluation results shown in table 4 clearly demonstrate that fabrics rinsed with use of example 1 composition containing optical brightener becomes brighter than that of unwashed fabrics even after twenty washings.
