Definitions

  • the present invention relates to treatment composition for fabrics, in particular the hand rinsing of fabrics as well as the rinsing of fabrics in top loaded non automatic washing machines which have been laundered with a detergent composition, especially a high suds composition.
  • the trends for washing is by using a washing machine whereby the laundry detergent and the softening composition are dispensed from the washing machine via two separate compartments, thereby ensuring the automated release of the detergent at the beginning of the washing process and the release of the softening composition in the rinse process, usually the last rinse process.
  • the washing in non automatic top loaded washing machines is operated by placing the fabric with detergent in the cubicle containing water and agitation, removing the fabrics from the cubicle containing the detergent liquor, placing the fabric in the spinning cubicle for spinning step, empty the detergent liquor from the other cubicle and replace it by fresh water and then put back the spinned fabrics for rinsing, the rinsing step of spinning, rinsing, and spinning being often reiterated several time to obtain acceptable rinsed fabrics.
  • hand-washing treatment of fabric in general, is not constrained to any particular geographical region. Although certain areas having limited access to modern appliances have a higher prevalence of laundering treatment by hand, the need to hand-wash, including rinsing, at least certain items of clothing appears universal. Hence, even with modern washing machine having the rinsing step, there are still many garments, especially those manufactured from "fine fabric” material (i.e. silk) or those which comprise “soft woven” material (i.e. woolen knitted sweaters) are commonly “laundered by hand", for example, "delicate” or "personal” items typically require hand-washing. Hand laundering treatment typically limits the temperature at which the fabric is washed, usually within a range tolerable to the person washing the garment.
  • a unique aspect of washing-by-hand, and/or washing in non automatic top loaded washing machine is the high detergent to water ratio and/or the high soil to water ratio (high soil loading).
  • fabric treated with such detergent usually become saturated with residual detergent and/or dirt and particulate matter upon transfer to the rinse step.
  • this problem of saturation is even more acute with manual washing and/or washing in non automatic top loaded washing machine, as it is due to the poor efficiency of the spinning and/or wringing in between the wash and the rinse steps.
  • Conventional detergent products which are currently used for the hand laundering and/or top loading non automatic washing machine treatments are the so called "High Suds Detergents".
  • Conventional rinsing step involves the step of contacting the laundered fabric with water so as to remove the soiled laundry liquor but the suds as well.
  • the clarity of the rinse water is an important factor for the consumer. Indeed, it is often perceived by the consumers as a signal of a thoroughly completed rinse. In other words, the more turbid the rinse water is, the more rinses are performed by the consumer, i.e. until a clear rinse solution is obtained. In the end, more water than is necessary is used to complete the rinse, particularly when a significant amount of residual detergent and soil are carried over the wash steps.
  • a fabric rinse treatment composition that has a clarity value upon dilution of less than a 0.04 % by weight of a dimethyl bis(steroyl oxyethyl) ammonium chloride aqueous solution and a suds reduction value of at least about 50% fulfill such a need.
  • the invention composition gives a reduced re-soiling of the fabrics during the rinsing steps.
  • the re-soiling is believed to arise from the excess of soil which is carried over from the wash to the rinse steps and/or of the use of water contaminated with heavy metal ion.
  • this composition has also been found effective in the pre-treatment or soaking of fabric to improve the cleaning end result benefits of the wash process. Not to be bound by theory, it is believed that the mechanism behind the improved cleaning benefit lies in the composition weakening the link between the residual soil present on the fabric and the cellulose fabric fiber, thereby enabling an easier removal in the subsequent wash process.
  • This additional advantage of the invention composition is particularly beneficial when water contaminated with heavy metal ions is used. Indeed, water contaminated with heavy metal ions is often the cause of re-soiling on fabrics upon treatment. Accordingly, it is an advantage of the invention to provide a pre- treatment composition and/or soaking composition which reduces or even prevents the resoiling of the fabric. Moreover, it has also been found that the use of the composition in both pre- treatment and/or soaking step and rinsing step allows an even better cleaning performance.
  • a fabric treatment composition comprising a suds suppressing system, characterised in that the composition which has a clarity value upon a 0.2% dilution of less than a 0.04% by weight of a dimethyl bis(steroyl oxyethyl) ammonium chloride aqueous solution and a suds reduction value of at least about 50%.
  • a method for rinsing fabrics which comprises the steps of contacting the fabrics, previously contacted with an aqueous detergent liquor, with a composition of the invention.
  • a method for pre- treating the fabrics which comprises the steps of applying in neat form the composition to the fabrics, and subsequently rinse or wash and rinse it.
  • a method for soaking the fabrics which comprises the step of contacting the fabrics with a composition of the invention, in its diluted form, before the fabrics are rinsed or washed and rinsed.
  • composition has a has a clarity value upon a 0.2% dilution of less than a 0.04% by weight of a dimethyl bis(steroyl oxyethyl) ammonium chloride aqueous solution.
  • Clarity Test Method The clarity of the treatment composition is one essential feature of the invention. Clarity is defined according to the following test method:
  • a reference composition is made containing 0.04% by weight of a C11- C22 diakylester quaternary ammonium compound, in particular, the dimethyl bis(steroyl oxyethyl) ammonium chloride, in deionised water at 70°C.
  • a C11- C22 diakylester quaternary ammonium compound in particular, the dimethyl bis(steroyl oxyethyl) ammonium chloride
  • test composition is then prepared by dilution of the composition to obtain a 0.2% diluted composition, using deionised water at the temperature required to solubilize or disperse all the actives.
  • compositions are subsequently evaluated for their clarity properties using a KONTRON Instrument Uvikon 933 set up on the following parameters:
  • Tested composition at 0.2% which have an intensity below or equal to that of the reference composition at 0.04% are suitable for the present invention provided they also meet the suds suppressing Test.
  • the suds reduction property of the hand treatment is another essential feature of the invention. Suds reduction is defined according to the following test method:
  • foam in the reference beaker remains at about 3cm.
  • Suitable compositions are those that have a suds reduction over the reference of about at least 50%, preferably of at least 80% and most preferably of at least 99%. 99% is where all the foam disappeared apart from the optional presence of a white film that may partially cover the surface of the solution.
  • the reduction of the suds is achieved by use of a suds suppressing system.
  • the suds suppressing system is preferably present at a level of from 0.01% to 99%, more preferably from 0.05% to 50%, most preferably from 0.1 % to 5% by weight of the composition.
