Definitions

  • the present invention relates to a method of ironing clothes, use of an aqueous composition in a steam iron to carry out the method, and to use of a concentrate, following dilution by water to produce an aqueous composition, in the method.
  • compositions which are diluted with water to give a aqueous product for addition to the water reservoirs of steam irons are commercially available in a number of countries. These compositions are used to prevent the formation of lime scale in the iron if water containing dissolved calcium and magnesium salts is used and to give a pleasant fragrance to the cloth being ironed.
  • US 5 409 619 discloses a composition for use in the steam chamber of a steam iron which comprises propylene glycol, glycerine, and optionally a volatile fragrance in deionized water.
  • the composition is said to provide improved glide characteristics.
  • EP-A-0 292 909 discloses an aqueous composition for removing wrinkles from a fabric or garment comprising an alcohol, glycerine and a nonionic surfactant.
  • the composition preferably contains a silicone compound to reduce any tackiness imparted by said glycerine to said fabric.
  • the de-wrinkling composition is sprayed on the wrinkled fabric or garment and allowed to dry.
  • GB-A-0 743 944 discloses a method of treating textile fabric or garments to improve the characteristics thereof by a pressing or ironing operation with steam, characterised by the steps of introducing into the steam a small amount of a composition having a liquid lubricant (oil) as the base, whereby the composition becomes diffused with the steam, and introducing the steam containing the composition diffused therein into the fabric during the pressing or ironing operation, whereby the composition is carried with the steam into the fabric and deposited onto the fibers to improve the body and finish thereof.
  • a water repellent e.g. an organo-silicon compound or Werner complex, may be incorporated into the lubricant.
  • a process for ironing cloth which comprises directing steam on to the surface of the cloth to deliver a lubricant to the cloth in the steam directed on to the cloth while applying heat and pressure to the cloth, wherein the lubricant is a steam-volatile silicone and the steam is generated from an aqueous composition comprising said steam-volatile silicone and a sequestering agent.
  • an aqueous composition in the water reservoir of a steam iron wherein the aqueous composition comprises a steam-volatile lubricant, which is a steam-volatile silicone, and a sequestering agent.
  • a concentrate following dilution with water to give an aqueous composition, in the water reservoir of a steam iron, wherein the concentrate comprises a steam-volatile lubricant, which is a steam-volatile silicone, and a sequestering agent.
  • the process of the present invention may be carried out using a conventional domestic steam iron having a reservoir for water communicating with openings in the sole (base) plate of the iron through which steam can be directed on to cloth which is being ironed.
  • the reservoir may be incorporated in the iron or may be a separate component connected to the iron by a flexible tube.
  • the lubricant is a silicone which is volatile in steam so that it can be carried to the cloth in the steam generated by the steam iron.
  • the lubricant will not adversely affect the appearance or the feel of the cloth. It is preferred for the lubricant to be dispersible in water. If the lubricant is not itself dispersible in water, then a surfactant may be used to keep it dispersed.
  • polydimethyl siloxanes modified by incorporation of polyoxyalkylene groups are also known as dimethicone polyols. Such compounds having surfactant properties are commercially available.
  • Two types of block co-polymers are available. One type is a linear polydimethylsiloxane to which polyethers have been grafted (by a hydrosilation reaction) to give an alkyl pendant (AP) polymer with the polyalkylene groups linked to the siloxane backbone by Si-C bonds, which are hydrolytically stable.
  • the preferred polymers have the formula where PE is a pendant group which is -CH 2 CH 2 CH 2 O(EO) m (PO) n Z and Z is lower alkyl, e.g. C 1 -C 4 .
  • ethoxy and propoxy groups may be present in a ratio corresponding to an ethylene oxide to propylene oxide molecular ratio of 40/60 to 100/0 and molecular weights in the range 4000 to 81000. It is preferred to use dimethicone polyols with molecular weights in the range 10000 to 30000, e.g. 10000 to 22000.
  • Another class of block co-polymer silicone surfactants are those obtained by condensing polyethers at the ends of the siloxane backbone through Si-O-C bonds.
  • silicone compounds are the cyclic polydimethyl siloxanes, which are also known as cyclomethicones.
  • the cyclic compounds are commercially available as the tetramers or pentamers. They may be obtained from Dow Corning under the designations Dc 244, 245, 344, and 345. These materials are water-insoluble and but may be emulsified with surfactants to give oil-in-water emulsions. The formula of the tetramer is given below.
  • silicones which may be used in the invention are the lower molecular weight polydimethyl silicones - [Si(CH 3 ) 2- O-[Si(CH 3 ) n ]-O-[Si(CH 3 ) 2 ]- which are available in a range of molecular weights and viscosities. It is preferred to use polydimethyl silicones with a molecular weight in the range 1000 to 20000.
  • the aqueous composition contains a sequestering agent.
  • the purpose of the sequestrant is to prevent the deposition of scale in the iron.
  • suitable sequestering agents are diethylene triamine penta-acetate.
  • the aqueous composition may contain a fragrance, as is used in known additives for steam irons.
  • a fragrance solubilizer may be included in the composition.
  • This may for example be a nonionic surfactant, for example sorbitan monolaurate 20EO, i.e. the product of reacting 20 molecules of ethylene oxide with each molecule of the sorbitan monolaurate.
  • the composition preferably contains a preservative to protect it against microbial attack. Suitable preservatives are well-known. Thus 4,4-dimethyl oxazolidine may be used.
  • the amounts of lubricant in the liquid which is vapourized to give the steam required in the ironing process may be in the range 0.001 to 5 % w/w of the total composition, preferably 0.001 % to 0.4% w/w.
  • the amount of sequestering agent present may be, for example, in the range 0.003% to 5% w/w, preferably 0.003% to 0.2% w/w
  • the concentrate which is mixed with water to give the aqueous composition used to deliver the lubricant in the ironing process may be a liquid, e.g. an aqueous liquid. Alternatively it may be a gel or a powder.
  • the amount of lubricant in the concentrate may be 0.05% to 20%, preferably 2 to 8%, e.g. 5% w/w.
  • the amount of sequestering agent in the concentrate may be 0.2 to 10.00 % w/w, preferably 0.3 to 0.7% w/w.
  • the amount of any fragrance present in the concentrate may be in the range 0.05% to 0.3%, e.g. 0.10% w/w.
  • the amount of any fragrance solubilizer in the concentrate may be from 0.1 to 0.3% w/w, e.g. 0.2%.
  • the remainder of the liquid may be water, preferably deionized water.
  • a composition was prepared from the following ingredients. Ingredient %wt/wt Deionized water 96.10 Preservative 0.10 Perfume 0.10 Sequestering agent 1.00 Lubricant 2.5 Surfactant 0.2
  • the preservative was 4,4-dimethyl oxazolidine, commercially available under the trade name "Bioban CS 1135 ".
  • the sequestering agent was diethylene triamine penta-acetate, commercially available under the trade name "Dissolvine D50".
  • the lubricant was a polyalkylene oxide silicone copolymer surfactant commercially available under the trade name "Silwet L7200" from OSi Specialities of Harefield, Middlesex, UK.
  • the polymer was an alkyl-pendant (AP) polymer as described above. It had a molecular weight of about 19000 and the polyoxyalkylene oxide component was derived from a mixture of ethylene oxide and propylene oxide in the molecular ratio 75:25.
  • the composition was prepared by mixing the ingredients together.
  • a composition was prepared as in Example 1 except that the lubricant was a cyclic polydimethyl silicone pentamer commercially available from Dow Coming as DC 245.
  • a composition was prepared as in Example 1 except that it contained no lubricant.
  • compositions of Examples 1, 2, and comparative Test A were subjected to a test with a panel of users who tested them in random order using a separate ironing board and iron for each product.
  • the products of Examples 1, 2 and Test A were tested at two different dilutions with tap water, namely 1:60 and 1:120 by volume.
  • the composition of Comparative Test A was tested at a dilution of 1:60. The testers were then asked questions about the products tested. The higher the score reported, the greater the agreement with the proposition put to the testers.
  • Example 1 (1:120) 5.92
  • Example 1 (1:60) 5.83
  • Example 2 (1:60) 5.75 Test A a low score was obtained
