Definitions

  • the present invention relates to preferably translucent, or, more preferably, clear, aqueous, concentrated, 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.
  • the present invention provides concentrated 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 dispersibility, together with excellent softening, anti-static and fabric rewettability characteristics, as well as reduced dispenser residue buildup and excellent freeze-thaw recovery.

(Daylight CIS), Irvine, California, contains many, along with citations to the original literature. However, 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.
  • C 1-2 mono-ols that provide the clear concentrated fabric softener compositions of this invention.
  • Only one C 3 mono-ol, n-propanol provides acceptable performance (forms a clear product and either keeps it clear to a temperature of about 4°C, or allows it to recover upon rewarming to room temperature), although its boiling point (BP) is undesirably low.
  • BP boiling point
  • Of the C4 monools only 2-butanol and 2-methyl-2-propanol provide very good performance, but 2- methyl-2-propanol has a BP that is undesirably low.
  • principal solvents which have two hydroxyl groups in their chemical formulas are suitable for use in the formulation of the liquid concentrated, clear fabric softener compositions of this invention. It is discovered that the suitability of each principal solvent is surprisingly very selective, dependent on the number of carbon atoms, the isomeric configuration of the molecules having the same number of carbon atoms, the degree of unsaturation, etc. Principal solvents with similar solubility characteristics to the principal solvents above and possessing at least some asymmetry will provide the same benefit. It is discovered that the suitable principal solvents have 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.
  • the 1,2-hexanediol is a good principal solvent, while many other isomers such as 1,3- hexanediol, 1,4-hexanediol, 1,5-hexanediol, 1,6-hexanediol, 2,4-hexanediol, and 2,5-hexanediol, having ClogP values outside the effective 0.15 - 0.64 range, are not.

  • premixes can optionally be replaced by a mixture of an effective amount of principal solvents B. and some inoperable solvents, as disclosed hereinbefore.
  • These premixes contain the desired amount of fabric softening active A. and sufficient principal solvent B., and, optionally, solvent C., to give the premix the desired viscosity for the desired temperature range.
  • Typical viscosities suitable for processing are less than about 1000 cps, preferably less than about 500 cps, more preferably less than about 300 cps.
  • Use of low temperatures improves safety, by minimizing solvent vaporization, minimizes the degradation and/or loss of materials such as the biodegradable fabric softener active, perfumes, etc., and reduces the need for heating, thus saving on the expenses for processing.
  • Additional protection for the softener active can be provided by adding, e.g., chelant such as ethylenediaminepentaacetic acid, during preparation of the active. The result is improved environmental impact and safety from the manufacturing operation.
  • the fabric softening actives (DEQAs); the principal solvents B.; and, optionally, the water soluble solvents, can be formulated as premixes which can be used to prepare the following compositions.

Abstract

L'invention a pour objet des solvants principaux, en particulier des solvants principaux mono-ol et diol, ayant un ClogP compris entre environ 0,15 et environ 0,64, de préférence entre environ 0,25 et environ 0,62, et plus avantageusement entre environ 0,40 et environ 0,60. Lesdits solvants permettent d'obtenir des compositions aqueuses et claires d'adoucisseurs de tissus contenant des concentrations relativement élevées d'agents actifs adoucissants de tissus dotés de liaisons d'ester dans leurs chaînes longues hydrophobes. Soit lesdits agents actifs sont insaturés, soit ils possèdent des chaînes de longueurs intermédiaires (∩C12-14) et lesdits solvants principaux sont utilisés à des teneurs inférieures à environ 40 %. D'autres solvants peuvent être présents. Certains de ces solvants principaux peuvent être des composés nouveaux et/ou des mélanges nouveaux. Des prémélanges de ces agents actifs adoucisseurs de tissus, de ces principaux solvants et, éventuellement, d'autres solvants peuvent être utiles dans la préparation de formulations complètes car ils permettent d'éviter ou de limiter le chauffage.
