Definitions

  • the present invention relates to preferably translucent, or, more preferably, clear, aqueous, liquid softening compositions useful for softening cloth. It especially relates to textile softening compositions for use in the rinse cycle of a textile laundering operation to provide excellent fabric-softening/static-control benefits, the compositions being characterized by, e.g., reduced staining of fabric, excellent water dispersibility, rewettability, and/or storage and viscosity stability at sub-normal temperatures, i.e., temperatures below normal room temperature, e.g., 25°C.
  • Fabric softening compositions containing high solvent levels are known in the art. However, softener agglomerates can form and can deposit on clothes which can result in staining and reduced softening performance. Also, compositions may thicken and/or precipitate at lower temperatures, i.e., at about 40°F (about 4°C) to about 65°F (about 18°C). These compositions can also be costly for the consumer due to the high solvent levels associated with making a concentrated, clear product.
  • EP-A-0 296 995 discloses softening compositions comprising a softening compound (A), a cationic compound (B) having a better water-solubility than (A), and a solvent (C).
  • WO-A-96/33800 published on 31 st October 1996, discloses a homogeneous liquid composition comprising one or more cationic, anionic, amphoteric or nonionic agent with a diol and/or diol alkoxylate like 2,2,4-trimethyl-1,3-pentane diol; the ethoxylate, diethoxylate, or triethoxylate derivatives of 2,2,4-trimethyl-1,3-pentane diol; and/or 2-ethylhexyl-1,3-diol.
  • the present invention provides aqueous liquid textile treatment compositions with low organic solvent level (i.e. below about 40%, by weight of the composition), that have improved stability (i.e. remain clear or translucent and do not precipitate, gel, thicken, or solidify) at normal, i.e. room temperatures and subnormal temperatures under prolonged storage conditions.
  • Said compositions also provide reduced staining of fabrics, good cold water dipersibility, together with excellent softening, anti-static and fabric rewettability characteristics, as well as reduced dispenser residue buildup and excellent freeze-thaw recovery.
  • the object of the present invention is to provide aqueous, translucent, or, preferably, clear, rinse-added liquid fabric softening compositions which provide one, or more benefits such as reduced staining on fabrics, ready dispersibility in rinse water, phase stability at low temperatures, and/or, preferably acceptable viscosity and viscosity stability at low temperatures, and/or recovery from freezing.
  • compositions herein comprise:
  • the principal solvents are desirably kept to the lowest levels that provide acceptable stability/clarity in the present compositions.
  • the presence of water exerts an important effect on the need for the principal solvents to achieve clarity of these compositions.
  • the softener active-to-principal solvent weight ratio is preferably from about 55:45 to about 83:15, more preferably from about 60:40 to about 80:20.
  • the softener active-to-principal solvent weight ratio is preferably from about 45:55 to about 70:30, more preferably from about 55:45 to about 70:30. But at high water levels of from about 70% to about 80%, the softener active-to-principal solvent weight ratio is preferably from about 30:70 to about 55:45, more preferably from about 35:65 to about 45:55. At higher water levels, the softener to principal solvent ratios should be even higher.
  • the pH of the compositions should befrom about 1 to about 7, preferably from about 1.5 to about 5, more preferably from about 2 to about 3.5.
  • the present invention contains as an essential component from about 2% to about 80%, preferably from about 13% to about 75%, more preferably from about 17% to about 70%, and even more preferably from about 19% to about 65% by weight of the composition, of a fabric softener active selected from the compounds identified hereinafter, and mixtures thereof.
  • compositions of the present invention comprise less than about 40%, preferably from about 10% to about 35%, more preferably from about 12% to about 25%, and even more preferably from about 14% to about 20%, of the principal solvent, by weight of the composition.
  • Said principal solvent is selected to minimize solvent odor impact in the composition and to provide a low viscosity to the final composition.
  • isopropyl alcohol is not very effective and has a strong odor.
  • n-Propyl alcohol is more effective, but also has a distinct odor.
  • Several butyl alcohols also have odors but can be used for effective clarity/stability, especially when used as part of a principal solvent system to minimize their odor.
  • the alcohols are also selected for optimum low temperature stability, that is they are able to form compositions that are liquid with acceptable low viscosities and translucent, preferably clear, down to about 40°F (about 4.4°C) and are able to recover after storage down to about 20°F (about 6.7°C).
  • any principal solvent for the formulation of the liquid, preferably clear, fabric softener compositions herein with the requisite stability is surprisingly selective.
  • Suitable solvents can be selected based upon their octanol/water partition coefficient (P).
  • Octanol/water partition coefficient of a principal solvent is the ratio between its equilibrium concentration in octanol and in water.
  • the partition coefficients of the principal solvent ingredients of this invention are conveniently given in the form of their logarithm to the base 10, logP.
  • the logP of many ingredients has been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, California, contains many, along with citations to the original literature.
  • the logP values are most conveniently calculated by the "CLOGP” program, also available from Daylight CIS: This program also lists experimental logP values when they are available in the Pomona92 database.
  • the "calculated logP” (ClogP) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p.
  • the fragment approach is based on the chemical structure of each ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding.
  • the ClogP values which are the most reliable and widely used estimates for this physicochemical property, are preferably, used instead of the experimental logP values in the selection of the principal solvent ingredients which are useful in the present invention.
  • Other methods that can be used to compute ClogP include, e.g., Crippen's fragmentation method as disclosed in J. Chem. Inf. Comput. Sci., 27, 21 (1987); Viswanadhan's fragmentation method as disclose in J. Chem. Inf. Comput. Sci., 29, 163 (1989); and Broto's method as disclosed in Eur. J. Med. Chem. - Chim. Theor., 19, 71 (1984).
  • the principal solvents herein are selected from those having a ClogP of from about 0.15 to about 0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60, said principal solvent preferably being asymmetric, and preferably having a melting, or solidification, point that allows it to be liquid at, or near room temperature. Solvents that have a low molecular weight and are biodegradable are also desirable for some purposes.
  • asymmetric solvents appear to be very desirable, whereas the highly symmetrical solvents, having a center of symmetry, such as 1,7-heptanediol, or 1,4-bis(hydroxymethyl)cyclohexane, appear to be unable to provide the essentially clear compositions when used alone, even though their ClogP values fall in the preferred range.
  • One can select the most suitable principal solvent by determining whether a composition containing about 27% di(oleyoyloxyethyl)dimethylammonium chloride, about 16-20% of principal solvent, and about 4-6% ethanol remains clear during storage at about 40°F (about 4.4°C) and recovers from being frozen at about 0°F (about -18°C).
  • the most preferred principal solvents can be identified by the appearance of the freeze-dried dilute treatment compositions used to treat fabrics. These dilute compositions appear to have dispersions of fabric softener that exhibit a more unilamellar appearance than conventional fabric softener compositions. The closer to uni-lamellar the appearance, the better the compositions seem to perform. These compositions provide surprisingly good fabric softening as compared to similar compositions prepared in the conventional way with the same fabric softener active. The compositions also inherently provide improved perfume deposition as compared to conventional fabric softening compositions, especially when the perfume is added to the compositions at, or near, room temperature.
  • Operable principal solvents are listed below.
  • the reference numbers are the Chemical Abstracts Service Registry numbers (CAS No.) for those compounds that have such a number.
  • Inoperable principal solvents can be used in mixtures with operable principal solvents.
  • Operable principal solvents can be used to make concentrated fabric softener compositions that meet the stability/clarity requirements set forth herein.
  • diol principal solvents that have the same chemical formula can exist as many stereoisomers and/or optical isomers.
  • Each isomer is normally assigned with a different CAS No.
  • different isomers of 4-methyl-2,3-hexanediol are assigned to at least the following CAS Nos: 146452-51-9; 146452-50-8; 146452-49-5; 146452-48-4; 123807-34-1; 123807-33-0; 123807-32-9; and 123807-31-8.
  • compositions containing both saturated and unsaturated diester quaternary ammonium compounds can be prepared that are stable without the addition of concentration aids.
  • the compositions of the present invention may require organic and/or inorganic concentration aids to go to even higher concentrations and/or to meet higher stability standards depending on the other ingredients.
