Abstract
A liquid detergent composition has a thickening system which comprises an admixture of linoleic acid and linolenic acid.
Description
COMPOSITION
This invention relates to aqueous liquid detergents, preferably for use as a laundry composition or in conjunction with a laundry detergent.
Liquid based laundry compositions have been known for many years. A major issue encountered with such compositions has been the achievement of a suitable viscosity for the liquid: the liquid has to be viscous enough so that any particles are suspended yet have a sufficiently high degree of flow for ease of manufacture and dispense by a consumer. To achieve the desired rheology typically thickeners are used. These thickeners are rheology modifiers suitable for liquid detergents. They are used to associate a higher concentration of active ingredients and to aggregate them in a stable matrix.
Numerous thickening systems have been developed over the years but there is still room for improvement in such systems, particularly as regards cost effectiveness and environmental concerns .
Different kinds of thickener are commercially available. One class of thickener that is used extensively are those based upon polymeric -carboxylic acids and their salts .
Whilst generally these thickeners are highly effective one significant disadvantage in their use is that their efficacy is highly dependent on the pH and ionic strength of the liquid in which they are employed. Indeed the thickening effect of carboxylic acid based thickeners is only significant in alkaline solutions and / or solution having low ionic strength when the carboxylic acid based thickeners are in a dissociate state .
In such a condition the thickening mechanism is based on 2 main effects :
In an alkaline environment the carboxylic acid dissociates to carboxylate anions. As a result the electrostatic repulsion of the anions causes the stretching of the polymer chain. This phenomenon reduces the degrees of freedom of the structure in the liquid matrix.
Moreover the carboxylate anions interact with the hydrophilic heads of the surfactant micelles, creating a tri-dimensional network between the thickener backbone and the micelles (associative effect) .
The result of these two effects in the right conditions is the increase of viscosity of the liquid.
It is therefore a primary object of this invention to develop stabilised laundry detergent composition (or a composition to be used in conjunction with a laundry detergent) which incorporates a low cost, but effective, thickening system over a broad range of conditions. According to the first aspect of the present invention there is provided a liquid detergent composition having a thickening system which comprises an admixture of linoleic acid and linolenic acid. With the thickening system of the present invention it has been found that superior thickening of a liquid detergent composition can be achieved. Without wishing to be limited by theory it is postulated that the superior thickening is brought about by Van der Waals interactions between the long carbon chains of the acids, which gives rise to the formation of micelles, and high viscosity.
Preferably the linoleic acid and linolenic acid are present in a ratio (by weight) of from 100:1 to 1:100, more preferably 50:1 to 1:50, most preferably about 12 :1.
The amount of the linoleic acid / linolenic acid admixture present in a final composition will be understood to depend on a number of factors, including; the component (s) of the final composition and the desired viscosity. In general for an (aqueous) liquid detergent composition having a viscosity in the range of 500 to 1500 cps, measured at 20°C, the amount of admixture present is from 0.1 to 30wt%, more preferably 0.5 to 20wt%, most preferably from 1 to 12wt%.
Preferably the admixture of linoleic acid and linolenic acid is present as part of a greater fatty acid admixture. A most preferred example of this fatty acid
composition (by weight) is shown below:-
Preferably the above admixture of linoleic acid and linolenic comprises from 0.1 to 30wt%, more preferably 0.5 to 20wt%, most preferably from 1 to 12wt%. of the liquid detergent composition.
Optionally the composition comprises from 0.001% to 99.99%, preferably 0.001% to 20%, preferably 4% to 18%, e.g. most preferably about 4.5% or 13%, by weight, of bleach .
Preferably the composition comprises a surfactant. Where present the composition comprises from 0.001% to 99.99%, preferably 0.05% to 40%, preferably 10% to 30%, e.g. about 25%, by weight of surfactant.
The surfactant is, for example, an anionic or nonionic surfactant or mixture thereof (most preferably a non- ionic surfactant) . The nonionic surfactant is preferably a surfactant having a formula RO (CH2CH20) nH wherein R is a mixture of linear, even carbon-number hydrocarbon chains ranging from Ci2H25 to Ci6H33 and n represents the number of repeating units and is a number of from about 1 to about 12. Examples of other non- ionic surfactants include higher aliphatic primary alcohol containing about twelve to about 16 carbon atoms which are condensed with about three to thirteen moles of ethylene oxide .
Other examples of nonionic surfactants include primary alcohol ethoxylates (available under the Neodol trade name from Shell Co.), such as Cn alkanol condensed with 9 moles of ethylene oxide (Neodol 1-9) , C12-13 alkanol condensed with 6.5 moles ethylene oxide (Neodol 23-6.5), C12-13 alkanol with 9 moles of ethylene oxide (Neodol 23- 9) , C12-15 alkanol condensed with 7 or 3 moles ethylene oxide (Neodol 25-7 or Neodol 25-3) , Ci -i5 alkanol con-
densed with 13 moles ethylene oxide (Neodol 45-13) , C9-11 linear ethoxylated alcohol, averaging 2.5 moles of ethylene oxide per mole of alcohol (Neodol 91-2.5), and the like.
Other examples of nonionic surfactants suitable for use in the present invention include ethylene oxide condensate products of secondary aliphatic alcohols containing 11 to 18 carbon atoms in a straight or branched chain configuration condensed with 5 to 30 moles of ethylene oxide. Examples of commercially available non-ionic detergents of the foregoing type are C11-15 secondary alka- nol condensed with either 9 moles of ethylene oxide (Tergitol 15-S-9) or 12 moles of ethylene oxide (Tergi- tol 15-S-12) marketed by Union Carbide, a subsidiary of Dow Chemical .
Octylphenoxy polyethoxyethanol type nonionic surfactants, for example, Triton X-100, as well as amine ox- ides can also be used as a nonionic surfactant in the present invention.
Other examples of linear primary alcohol ethoxylates are available under the Tomadol trade name such as, for ex- ample, Tomadol 1-7, a Cn linear primary alcohol ethoxy- late with 7 moles EO; Tomadol 25-7, a Ci2-C15 linear primary alcohol ethoxylate with 7 moles EO; Tomadol 45-7, a Ci -C15 linear primary alcohol ethoxylate with 7 moles EO; and Tomadol 91-6, a C9-Cn linear alcohol ethoxylate with 6 moles EO .
Other examples of linear primary alcohol ethoxylates are available under the Lutensol trade name such as, for example, Lutensol A3N, a C13-15 linear primary alcohol eth- oxylate with 3 moles EO; Lutensol LA60, a Ci3-i5 linear primary alcohol ethoxylate with 7 moles EO. Also Ge- napol such as, for example, Genapol LA3 , a C13-15 linear primary alcohol ethoxylate with 3 moles EO; Genapol LA070, a C13-i5 linear primary alcohol ethoxylate with 7 moles EO
Tomadol 45-7, a C14-C15 linear primary alcohol ethoxylate with 7 moles EO; and Tomadol 91-6, a C9-Cn linear alcohol ethoxylate with 6 moles EO.
Other nonionic surfactants are amine oxides, alkyl amide oxide surfactants.
Preferred anionic surfactants are frequently provided as alkali metal salts, ammonium salts, amine salts, ami- noalcohol salts or magnesium salts. Contemplated as useful are one or more sulfate or sulfonate compounds
including: alkyl benzene sulfates, alkyl sulfates, alkyl ether sulfates, alkylamidoether sulfates, alkylaryl pol- yether sulfates, monoglyceride sulfates, alkylsul- fonates, alkylamide sulfonates, alkylarylsulfonates , olefinsulfonates , paraffin sulfonates, alkyl sulfosucci- nates, alkyl ether sulfosuccinates , alkylamide sulfosuc- cinates, alkyl sulfosuccinamate , alkyl sulfoacetates , alkyl phosphates, alkyl ether phosphates, acyl sarconsi- nates, acyl isethionates , and N-acyl taurates. Gener- ally, the alkyl or acyl radical in these various compounds comprise a carbon chain containing 12 to 20 carbon atoms .
Other surfactants which may be used are alkyl naphtha- lene sulfonates and acyl / oleoyl sarcosinates and mixtures thereof.
