Description

LIQUID DETERGENT 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 and additive compositions have been known for many years. A major issue encountered with such compositions has been the achievement of a suitable viscosity for the formula: 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. Further the liquid has to be stable for over time/shelf life of the product. These problems are exacerbated for liquids which contain an oxidizing agent in an acidic environment.
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 to stability in the presence of oxidixing agents {such as H2O2) , and for effectiveness in acidic water formulation. 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, including acidic oxizing acquesous solutions.
According to the first aspect of the present invention there is provided an acidic bleach containing liquid detergent composition having a self thickening system which comprises (a) a nonionic surfactant in an amount of 10 to 15wt%,
(b) an anionic surfactant in an amount of 5 to 10wt%,
(c) a semi-polar nonionic surfactant (e.g. amine oxide) in an amount of 0.1 to 5wt% . 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 effect is due to interaction between semi-polar nonionic surfactant and the nonionic surfactant, giving rise to a thickened liquid. Furthermore advantageously the thickening is achieved in the absence of conventional surfactants (such as LAS / mineral surfactants), which are associated with a negative environmental impact.
Preferably the nonionic surfactant comprises an admixture of C12-C14 alcohols with 7 EΟ groups and C12-C16 alcohols with 3 EO groups.
Preferably the anionic surfactant comprises sodium lauryl sulfate.
Preferably the semi-polar nonionic surfactant comprises tri-methyl amine oxide. Preferably 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. The bleach is preferably peroxide bleach, most preferably hydrogen peroxide. Peroxide sources other than H2O2 can be used.
Preferably the composition comprises a surfactant. Where present the composition comprises from 0.001% to 99.99%, preferably 0.05% to 15%, e.g. about 7%, 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 ( CH2CH2O ) nH wherein R is a mixture of linear, even carbon-number hydrocarbon chains ranginq from C1 2H25 to C16H33 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) , C14-15 alkanol condensed with 13 moles ethylene oxide (Neodol 45-13), Cg-n 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 de- tergents of the foregoing type are C11-15 secondary alkanol 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 surfac- tants, for example, Triton X-100, as well as amine ox- ides can also be used as a nonionic surfactant in the present invention.
