Definitions

  • the present invention relates to compositions for washing textile materials in automatic cycles characterized in that the builder additives contained in said compositions are constituted by, or comprise, in mixture with conventional builders, one or more polyaminoacid(s) at a level of less than 5% by weight.
  • woven materials within the context of the instant invention, woven materials or textile fibres either of natural origin or man-made, are meant.
  • composition By the terms “composition”, “formulation” or “formulate”, those products are meant within the context of the present invention, which are designed for use in textile materials washing.
  • Zeolite A sodium alumino silicate
  • Zeolite A is used both in powder and in liquid compositions.
  • this product is acceptable: it does not constitute a risk for water bodies and, by being inorganic and insoluble, it does not increase the BOD load to waste waters treating facilities.
  • Zeolite A displays good adsorption capabilities for dyes and pigments released by fabrics and its ion-exchange capability increases with increasing temperature.
  • Drawbacks are its slow exchange kinetics, in particular as regards magnesium, its absence of buffering action, and its having to be dispersed.
  • Zeolite A is always used in association with other components (referred to as “builder additives” or “co-builders”).
  • the presently used products for such a purpose are sodium salts of polymeric polycarboxy acids.
  • acrylic acid-maleic anhydride copolymers are those which proved to be the most efficient ones.
  • laundry detergents contain from 2 to 4% of polymers, usually acrylic-maleic copolymers, also combined with other builders.
  • polyaminoacids can be used as builders or co-builders in detergent formulations, because they display extremely good calcium complexing capabilities and inhibit the formation of CaCO3 crystal germs, provided that they are used at concentrations of not less than 5%.
  • detergent formulations which comprise, as builders or co-builders, polyaminoacids at concentrations comprised within the range of from 0.5 to 5% by weight; particular advantages were attained when polyaspartates were used.
  • the present invention relates to suitable compositions for textile material washing, characterized in that they contain surfactants and other salts.
  • anionic surfactants we may remind here, for exemplifying purposes, sodium, potassium or ammonium salts of linear-chain C10-C20 fatty acids, alkyl sulfates, alkylbenzene sulfonates, alkane sulfonates, hydroxyalkane sulfonates, alkene sulfonates and alkyl ethoxy sulfates; we furthermore wish to cite various sulfonates, such as alkyl sulfosuccinates and alkali-metal and/or ammonium N-acyl-N-methyl taurinates, and so forth, or mixtures thereof.
  • nonionic surfactants we would mention, for exemplifying purposes, the products of condensation of ethylene oxide with substances containing active hydrogen atoms, such as C10-C20 fatty acids; as well as amides, fatty alcohols and amines, sucrose esters and alkyl phenols with C6-C12 alkyl chains; as nonionic surfactants, also amino oxides may be cited.
  • ampholytic surfactants may we cite in general those compounds which derive from aliphatic amines, characterized by the presence of at least one C8-C18 chain and at least one chain containing a hydrophylic anionic moiety, e.g., a carboxy or sulfonic acid group.
  • Those agents which complex alkali-earth cations according to the present invention are commonly defined as “builders” and, as already said, perform several positive actions for the purposes of good textile washing results.
  • builders One of most important among these actions, consists in sequestering metal ions, in particular alkali-earth metal ions, which constitute the water hardness (Ca++, Mg++).
  • inorganic compounds such as, e.g., water-soluble alkaline salts, such as carbonates, silicates, etc., or water insoluble compounds, such as alumino silicates, e.g., natural or synthetic zeolites; furthermore, water soluble organic compounds such as alkali-metal or ammonium salts of polycarboxy acids (citric acid, carboxy-methyloxy succinic acid, oxydisuccinic acid, and so on), are suggested.
  • water-soluble alkaline salts such as carbonates, silicates, etc.
  • water insoluble compounds such as alumino silicates, e.g., natural or synthetic zeolites
  • water soluble organic compounds such as alkali-metal or ammonium salts of polycarboxy acids (citric acid, carboxy-methyloxy succinic acid, oxydisuccinic acid, and so on)
  • optical brighteners for simultaneous textile washing and brightening, the optical brighteners from DAA (aminostilbene-disulfonic derivatives), DP (pyrazolinic) and AC (aminocoumarinic) series may be mentioned here.
  • DAA aminostilbene-disulfonic derivatives
  • DP pyrazolinic
  • AC aminocoumarinic
  • said formulations may contain, as bleaching agents, oxidixing or reducing compounds, such as, e.g., hydrogen peroxide, alkali-metal perborate, preferably sodium perborate, sodium percarbonate, hypochlorites, chlorites, phosphites, hydrosulfites.
  • oxidixing or reducing compounds such as, e.g., hydrogen peroxide, alkali-metal perborate, preferably sodium perborate, sodium percarbonate, hypochlorites, chlorites, phosphites, hydrosulfites.
  • bleach activators such as, e.g., tetraacetylenediamine, TAGU, pentaacetyl glucose, nonanoyl phenol sulfonate (sodium salt), and so forth.
  • organic peroxides such as peracetic acid, dodecanediperdioic acid, phthalimino caproic acid, and so forth.
  • the formulates according to the present invention may obviously contain other common ingredients, such as, e.g., perfumes, antifoaming agents, stabilizers, anticaking agents, buffering agents, through-the-wash colour protecting agents, and, finally, extenders, such as, e.g., sodium sulfate.
  • other common ingredients such as, e.g., perfumes, antifoaming agents, stabilizers, anticaking agents, buffering agents, through-the-wash colour protecting agents, and, finally, extenders, such as, e.g., sodium sulfate.
  • the formulates according to the present invention also contain at least one poly-amino acid, which can also be in partially solidified form, at a concentration comprised within the range of from 0.5 to 5% by weight and, possibly, a conventional co-builder selected from the copolymers of maleic anhydride and/or acrylic acid with such natural substances as starch or dextrins or glucose, copolymers of maleic anhydride and compounds bearing allyl or vinyl moieties, maleic anhydride/ ethylene oxide copolymers, glyoxylic acid/formaldehyde copolymer, and still other polyelectrolytes.
  • a conventional co-builder selected from the copolymers of maleic anhydride and/or acrylic acid with such natural substances as starch or dextrins or glucose, copolymers of maleic anhydride and compounds bearing allyl or vinyl moieties, maleic anhydride/ ethylene oxide copolymers, glyoxylic acid/formaldehyde copolymer,
  • the molecular weight of useable polyaminoacids can be comprised within the range of from 1,000 to 300,000, preferably of from 10,000 to 100,000, with a salification degree preferably comprised within the range of from 70 to 85%.
  • composition for the detergent formulations according to the present invention can be as follows: * Surfactants 5-40% by weight * 4A Zeolite 5-50% by weight * Polymer 0.5-5% by weight * Sodium perborate tetrahydrate 0-30% by weight * Tetraacetyl ethylene diamine 0-5% by weight * Sodium disilicate 0-10% by weight * Sodium carbonate 5-25% by weight * CMC 0-2% by weight * Enzymes 0-1% * Perfume, antifoamers, etc. 0-2% * Sodium sulfate + H2O q.s. to 100%
  • wash tests were carried out by using formulations which contained either sodium salts of polyaminoacids as co-builders, or, as reference, 85%-salified 1:2 maleic-acrylic copolymers with an average molecular weight of 75,000, as well as mixtures thereof.
  • test conditions were as follows: * Tested fabrics EMPA 103 (combined strips) White WfK cloth * Wash temperature 90°C * Water hardness 40°fH * Washing liquor pH 10.5 * Detergent concentration 10 g/l
  • composition (values as % by weight) of the detergent used was the following: * C11-C13 alkylbenzene sulfonate 7.0 * C12-C22 soap 2.0 * Lialet-145.7 EO (oxo C14 ⁇ 15 alcohol + 7.0 mol of EO) 5.0 * Polymer 0 - 4 * 4A Zeolite 27.0 * Sodium perborate tetrahydrate 20.0 * Tetraacetyl ethylenediamine 4.0 * Sodium disilicate 3.0 * Sodium carbonate 10.0 * Enzyme 0.4 * Sodium sulfate + H2O q.s. to 100
  • CMC carboxymethylcellulose
