Abstract
Abstract The invention pertains to suspending aqueous built liquid detergent compositions comprising an anionic detergent active, electrolyte salts and a fatty alcohol polyalkylene oxide carboxylate salt. Inclusion of the carboxylate salt renders the rheology of the composition less sensitive to electrolyte materials.
Description
C 7040 (R) 1~328l7 LIQUID DETERGE~ COMPOSITIONS
The present invention relates to liquid detergent come positions and in particular to aqueous built liquid detergent compositions comprising a detergent active-bayed suspending system capable of suspending undies-solved material.
Aqueous built liquid detergent compositions are well known and a vast amount of formulations have been desk cried in the prior art. Generally such compositions comprise one or more detergent-active compounds and one or more builder salts in an aqueous medium which is capable of suspending undissolved builder and/or adjutant materials.
However, an important disadvantage of this type of con-ventional built liquid detergent is its extreme sense-tivity to electrolyte level. This sensitivity results in formulation regions of physical stability and accept table viscosity which greatly vary in magnitude and position as a function of the amount of dissolved elect trolyte. In particular, sufficient quantities of the more soluble builders, such as NAT, are difficult to incorporate without rendering the liquid unstable and liable to precipitation or phase separation.
It is therefore an object of invention to provide come positions of the above type which have reduced sense-tivity to electrolyte material and which tolerate larger quantities of such material without giving rise to unacceptable viscosities.
It has now been found that inclusion of relatively small quantities of specific fatty alcohol polyglycolether-derived anionic surfactants, optionally replacing part of the conventional anionic surfactant, reduces the , `

2 123Z8~7 sensitivity of the rheology to electrolyte materials, in particular, to builder and simple electrolyte salts.
Accordingly, the present invention provides an aqueous built liquid detergent composition capable of suspend-in particulate material, which comprises a synthetic anionic detergent-active material and electrolyte salts, characterized in that it comprises from 0.5-10%
by weight of a fatty alcohol polyalkylene oxide car boxy-late salt or a mixture of such salts according to the formula :
R-(OCnH2n)X~O(CH2)y~COOM
wherein R is an aliphatic hydrocarbon group having 8-20 carbon atoms or an aliphatic-aromatic hydrocarbon group having 4-20 carbon atoms in the aliphatic part; n is a number in the range of from 2 to 3 inclusive; x is a number in the range of from 1 to 16 inclusive; y is a number in the range of from 0 to 2 inclusive; and M is a cation.
The alkyd polyalkylene oxide carboxylate salt of the present invention is characterized by the formula :
WRECK Ho ) -Ouch COO
wherein R is an aliphatic hydrocarbon group having 8-20 carbon atoms or it may be an aliphatic-aromatic hydra-carbon group having 4-20 carbon atoms in the aliphatic part. R will normally comprise a mixture of aliphatic hydrocarbon groups of different lengths which may be straight or branched, saturated or unsaturated. Prefer-ably R is a straight saturated aliphatic hydrocarbon group having from 1-14 carbon atoms.
The polyalkylene oxide portion (OCnH2n)X prefer-ably comprises only ethylene oxide units no but also C 7040 (R)
Accordingly, the present invention provides an aqueous built liquid detergent composition capable of suspend-in particulate material, which comprises a synthetic anionic detergent-active material and electrolyte salts, characterized in that it comprises from 0.5-10%
by weight of a fatty alcohol polyalkylene oxide car boxy-late salt or a mixture of such salts according to the formula :

R will normally comprise a mixture of aliphatic hydrocarbon groups of different lengths which may be straight or branched, saturated or unsaturated. Prefer-ably R is a straight saturated aliphatic hydrocarbon group having from 1-14 carbon atoms.
The polyalkylene oxide portion (OCnH2n)X prefer-ably comprises only ethylene oxide units no but also C 7040 (R)
3 Z 3 2 8 7 propylene oxide or mixtures of propylene Oxide and ethylene oxide are suitable I no 3). The number of ethylene Andre propylene oxide units (x) may range from 1-16, in particular from 1-12. Preferably the alkaline oxide portion comprises from 2-5 ethylene oxide units.
The carboxylate portion ((CH2)y~COOM) preferably comprises no alkyd chain (yo-yo), but short alkyd chains such as ethylene and ethylene are also suitable. M is a cation and is selected from the group of hydrogen, sodium, potassium, ammonium, moo-, dip and triethanol ammonium, the alkali metal cations being preferred.
In the detergent compositions according to the present invention the fatty alcohol polyalkylene oxide car boxy-late salt or a mixture of such salts is included in an amount of from 0.5-10%, optionally partly replacing the synthetic anionic detergent-active material. The preferred amount depends on the rheology of the come position without the carboxylate salt compound, and the rheology which is aimed at. In general the best results are obtained when the fatty alcohol polyalkylene oxide carboxylate salt is included in an amount of from 2-5%
by weight, replacing about an equivalent amount of synthetic anionic detergent active material.
The invention is particularly applicable to aqueous liquid built compositions on the basis of synthetic anionic detergent-active material and electrolyte salt. Suitable synthetic anionic detergent-active materials comprise the well-known anionic detergents of the alkylaryl sulphonate type, the alkyd- and alkyd-ether sulfite type, the Al Kane- and alkene sulphonate type, etc. Numerous other examples can be found in Schwartz, Perry "Detergents and Surface-Active Agents", Vol. II, 1958.
C 7040 (R) Preferably alkylaryl sulphonates are used, in which the alkyd chain contains 10-18 carbon atoms, such as n-dodecyl Bunsen sulphonate, tetrapropylene Bunsen sulk fount, n-pentadecyl Bunsen sulphonate, and linear C12-C15 alkylbenzene sulphonate in which the elf-phatic group is obtained from cracked wax polymers, all in the form of their sodium or potassium gaits.
The total amount of synthetic anionic detergent active materials lies within the range of 1-15% by weight, preferably 6-12~ by weight of the total composition.
Although the anionic materials are the major detergent-active constituents, small amounts of other detergent-active materials can be tolerated, in particular non-ionic detergent-active materials. Non ionic detergents usually consist of a hydrophobic moiety which has been reacted with an alkaline oxide.
Suitable examples are primary or secondary, straight or branched chain C8-C18 alcohols condensed with 1-30 moles of alkaline oxide; moo- or dialkyl phenols with an alkyd group of 9-18 carbon atoms condensed with 1-30 moles of alkaline oxide; C10-Cl8 fatty acid moo-or dialkylol asides condensed with 1-30 moles of alkaline oxide; block copolymers of different or ides-tidal alkaline oxides and so on. Usually the alkaline . oxide is ethylene oxide, but propylene oxide or a mixture of ethylene oxide and propylene oxide can also be used. Further suitable examples can be found in the Jo text book of Schick "Non ionic Surfactants".
The amount of non ionic detergent-active material which can be included in the composition ranges up to 5%, but such amounts should be less than the amount of synthetic anionic detergent active material.
C 7040 (R) The electrolytes which are used in the present invention are those which cause partial salting out of the deter-gent active material. In general the composition may contain from 1-60% by weight, preferably 3-50% by weight and particularly preferably 5-30~ by weight of the electrolyte.
Typical examples are builder salts, such as the alkali metal ortho- and pyrophosphates, the alkali metal ammonium tripolyphosphates, such as sodium tripolyphos-plate, the alkali metal citrates, alkali metal salts of neutral triacetate and alkali metal salts of car boxy methyloxy succinate.
Suitable examples of electrolytes are also buffering agents, such as the alkanol amine, in particular in-ethanol amine, alkali metal carbonates, alkali metal borate, alkali metal silicates, and so on.
The compositions of the invention may further contain all ingredients usually encountered in such products, such as alkali metal sulfites, for improving detergent cry; enzymes, either alone or in combination with enzyme stabilizers, such as polyalcohols or alkanol amine with borax; fluoresces, further builders, such as zealots; abrasives, such as calcite; soil-suspending agents; anti-redeposition agents; hydrotropes, corrosion inhibitors; foam boosters or depressors; pacifying agents; perfumes, coloring agents; bleaching agents, optionally in combination with bleach precursors;
fluoresces.
The products of the present invention can be prepared using conventional techniques. In this respect it has been found that it is advantageous to shear the product at the end of the production process to its maximum stable viscosity, e.g. by post-stirring or passing the C 7040 (~) product through a disintegrator or similar high-shear exerting equipment. Further shear exerted on the product thus treated during pumping and bottling does not affect the viscosity of the product.
The invention will now be further illustrated by way of example, in which all percentages are by weight of the final composition Example Compositions were prepared according to the formulations listed in Table 1, having good physical stability and clearly showing the increased tolerance to high electron lyre levels.
