Definitions
- the present invention relates to detergent compositions. More specifically it relates to detergent compositions containing a fabric-softening amount of a hectorite clay, the clay being in the form of particles having a narrowly-defined layer charge distribution.
- British Patent 1 400 898 discloses detergent compositons comprising, as a fabric-softening ingredient, a smectite-type clay. Any smectite-type clay having a cation exchange capacity of at least 50 meq/100 g is taught to be suitable. Gelwhite GP and Volclay BC, both of which are sodium montmorillonite clays, are disclosed to be preferred for reasons of color and cation exchange capacity.
- an object of the present invention to provide detergent compositions comprising a fabric-softening clay from which the clay particles are more efficiently desposited onto fabrics during the laundry process. It is another object of the present invention to provide detergent compositions from which clay particles are efficiently deposited, regardless of the builder system used. It is a further object of this invention to select clay materials for use in detergent compositions that provide a signficiantly better fabric-softening performance than the clay materials used to date in commercial softeness-through-the-wash detergent compositions.
- the present invention relates to detergent compositions containing a fabric-softening amount of a fabric-softening clay.
- the amount of clay is from 1% to 25% by weight of the detergent composition.
- Said fabric-softening clay is a hectorite clay of natural origin, commonly referred to as trioctahedral smectite.
- the clay is present in the form of particles. The particles have a narrowly defined layer charge distribution, such that at least 50% of the clay has a layer charge of from 0. 23 to 0. 31.
- the detergent compositions of the present invention comprise conventional detersive surfactants, conventional detergent builders and, optionally, other conventional detergent ingredients.
- the compositions further comprise a fabric-softening amount, typically from 1% to 25% by weight of the detergent composition, of a fabric-softening clay.
- the clay which is of the smectite-type, is selected on basis of its layer charge properties.
- the value of (x + y) is the layer charge of the hectorite clay.
- the hectorite clays suitable for the detergent compositions of the present invention have a layer charge distribution such that at least 50% is in the range
- hectorite clays of natural origin having a layer charge distribution such that at least 65% is in the range of from 0. 23 to 0. 31.
- the layer charge distribution of the clay material can be determined using its swelling in the presence of cationic surfactants having specific chain lengths. This method is described in detail by Lagaly and Weiss, Zeitschrift fuer Deernaehrung und Bodentechnik, 130(1), 1971, pages 9-24, the disclosures of which are incorporated herein by reference.

- the method is described in S. Kawabata, "The Standardization and Analysis of Hand Evaluation", 2nd Ed. , Textile Mach. Soc. of Japan, Osaka, 1980, the disclosures of which are incorporated herein by reference.
- the shear hysteresis parameter 2HG5 is particularly useful in the characterization of fabric softening clays.
- Preferred herein are hectorite clays which, when incoporated in detergent compositions at 10% by weight, reduce the shear hysteresis of fabrics laundered therein by at least 32%, more preferably by at least 35%.
- the shear hysteresis parameter 2HG5 is discussed in more detail in Finnimore and Koenig, Melliand Textilberichte 67 (1986) pages 514-516, the disclosures of which are incorporated herein by reference.
- Shear hysteresis is determined on cotton terry towels, with detergent compositions containing 10% (weight) of the clay to be tested. The test is described more fully in the Examples hereinbelow.
