Definitions

  • This invention relates to light duty liquid detergents having particular utility in the hand washing of dishware, including dishes, pots, pans, glassware and silver/flatware. More particularly, it relates to a liquid dishwashing detergent composition which provides stable, persistent foaming characteristics combined with effectiveness in removing greasy soils from dishes under ambient, i.e. low water temperature, conditions.
  • Foam generation by detergent compositions is associated by the consumer with good detersive ability. However, it is apparent that long lasting foam, whether considered copious or medium to low-medium foam content is, by itself, not a sufficient measure of cleaning ability. Nevertheless, much effort has been extended to optimize foaming characteristics, without necessarily improving cleaning ability.
  • Greasy soils are generally considered to be one of the most difficult soil types to be removed by hand washing. Effective grease removal is nearly always associated with requiring high temperature water to help dissolve and remove the grease.
  • compositions which accomplish this objective.
  • the compositions - although prepared from otherwise known ingredients, but in unique combinations and proportions, is capable of achieving a new and beneficial result.
  • the liquid dishwashing detergent composition comprises, as essential ingredients: (A) from about 30 to 50% of a surfactant system comprising (1) from about 35 to 65% of a magnesium salt of a C 10 -C 15 alkyl benzene sulfonate anionic surfactant; (2) from 0 to 15% of an alkali metal salt of a 10 -C 16 alkyl benzene sulfonate anionic surfactant; and (3) from about 35 to 65% of an alkyl mono- or polyglucoside having from 9 to 13 carbon atoms, on average, in the alkyl chain, and an average degree of polymerization in the range of from about 1 to 3; and (B) from about 0.5 to 6% of a foam stabilization system comprising at least one lower alkanolamide of higher alkanoic acid, the balance water.
  • a surfactant system comprising (1) from about 35 to 65% of a magnesium salt of a C 10 -C 15 alkyl benzene sulfonate ani
  • (E) other adjuvants such as, chelating or sequestering agents, coloring agents, dyes, perfumes, bactericides, fungicides, preservatives, sunscreening agents, pH modifiers, pH buffering agents, opacifiers, antioxidants, thickeners, proteins, and the like, up to about 20%, in total, with a maximum of any individual component being about 10%.
  • the first essential surfactant ingredient is the anionic magnesium salt of an alkyl benzene sulfonic acid, preferably a linear C 10 to C 16 alkyl benzene sulfonate.
  • the linear alkyl group more preferably averages from 10 to 12 carbon atoms, and most preferably averages 12 carbon atoms.
  • the most preferred Mg alkyl benzene sulfonate is the magnesium salt of linear dodecylbenzene sulfonic acid.
  • the magnesium salt may be, for example, a magnesium oxide neutralized linear dodecyi benzene sulfonic acid, or alternatively, the magnesium salt may be formed by adding a magnesium salt, such as magnesium chloride, magnesium sulfate, etc. to sodium dodecyi benzene sulfonate. In the latter alternative, any excess of the magnesium salt electrolyte will raise the cloud/clear point of the composition. This undesirable effect can, however, be compensated for by addition of hydrotrope, as described below.
  • the Mg salt anionic surfactant (1) is present in an amount of from about 15% to about 25%, based on the total composition, or in an amount of from about 35 to 65%, based on the total surfactants (A) (1) , (2) and (3) .

  • the surfactant system may also include a small amount, up to about 5% of the total composition, or up to about 15% of the total surfactant component, of an alkali metal salt of a linear C 1Q -C 15 alkyl benzene sulfonic acid anionic surfactant.
  • the preferred amounts are up to about 3% (total) or about 8% (surfactant) , respectively, such as about 0.5, 1.0, 1.5, 2.0, or 3.0 percent, of the total composition.
  • the alkali metal may be sodium or potassium, preferably sodium.
  • the linear alkyl group preferably contains from 10 to 12 carbon atoms, especially 12 carbon atoms, on average, e.g. sodium linear dodecyi benzene sulfonate.
  • the sodium salt anionic is generally considered to be a milder detergent than the magnesium salt but is less effective for greasy soil removal and is also less effective in generating foam, especially in the presence of soil and, therefore, its presence in the composition will be minimized or
  • magnesium salt anionic is obtained by reacting an electrolyte magnesium salt with sodium alkyl benzene sulfonate, it is not generally necessary to remove any remaining sodium ion and, in fact, this is a convenient means for introducing the magnesium salt into the composition when its presence is desired.
  • Another essential surfactant in the invention composition is an alkyl glucoside, preferably an alkyl polyglucoside, although alkyl monoglucoside can also be used.
  • alkyl mono- and polysaccharides have received much attention recently for their beneficial detergent, foaming and viscosity modifying properties.

  • the number of glucoside units in any particular surfactant molecule will be a whole number (i.e. an integer) , however, for any actual physical sample of alkyl glucoside surfactants there will, in general, be a range of glucoside units, and it is the average value which characterizes a particular surfactant product, "
  • the alkyl group is preferably attached at the 1-position of the sugar molecule, but may be attached at the 1-, 3-, or 4-po ⁇ itions, thus giving a glucosyl rather than a glucoside. Furthermore, in the polyglucosides, the additional glucoside units are predominantly attached to the previous glucoside at the 2-position, but attachment at the 3-, 4- and 6-positions can also occur.

  • the amount of the alkyl glycoside surfactant to achieve the desired foam and detersive properties is in the range of from about 15 to 25% of the total composition, or from about 35 to 65% of the sum of the surfactants (A) (1) , (2) and (3) .
  • the preferred amounts range from 16 to 22%, especially from 18 to 20%, based on the total composition, or from about 40 to 60%, especially from 45 to 55%, based on the total surfactant content.
