The present invention relates to an aqueous built liquid detergent composition More particularly it relates to an improvement in the storage stability of aqueous built liquid detergent compositions, obtained by the inclusion of a particular hydrotrope system therein.
It is well known that aqueous built liquid detergent compositions may suffer 10 from storage instability leading to phase-separation, both at room temperature and at temperatures below O C, if no proper precautions have been taken.
Furthermore, aqueous built liquid detergent compositions are normally required to be homogeneous, clear liquids, which also demands special precautions.
One of the common practices to achieve stable, homogeneous, clear liquids is 15 to incorporate hydrotropes in aqueous built liquid detergent compositions, which solubilize particular ingredients in the liquid compositions Commonly employed for said purpose are hydrotropes such as urea, ethylalcohol, toluene-, curmene and xylene sulphonates However, whereas such hydrotropes may give the desired effects, the amount required may be rather high, or, with particular aqueous built 20 liquid detergent compositions, they may not produce the required degree of homogeneity, clarity and storage stability.
It has now been found that a hydrotrope system comprising a sulphonatetype hydrotrope of the general formula 503 M 25 R in which R is a methyl, dimethyl or isopropyl residue and M=H, NH 4, substituted NH 4, or an alkali metal, such as sodium or potassium, and an alkane phosphonic acid of the general formula R-P-OM, OM in which R is a saturated alkyl residue with 4-10 carbon atoms, and M is H, NH 4, 30 substituted NH 4 or an alkali metal such as sodium or potassium, significantly improves the homogeneity, clarity and storage stability of built aqueous liquid detergents.
In comparison with the sulphonate-type hydrotropes alone, the combination enables a significant reduction of the amount of sulphonate-type hydrotrope used, 35 while simultaneously improving the overall hydrotrope effect, and vice versa with regard to the alkane phosphonic acid alone.
2 1,576,412 2 The sulphonate-type hydrotropes are toluene-, xylene and cumene sulphonates, preferably in the form of the sodium or salts, although potassium, ammonium and substituted ammonium salts may also be used if desired.
Particularly preferred are sodium toluene and xylene sulphonate.
The other hydrotrope is a monoalkane phosphonic acid, in which the alkane 5 residue may be branched-, but is preferably straight-chained, and contains from 4-10 carbon atoms It may be used in the acid form, or in the form of the mono or dialkali metal such as sodium or potassium, ammonium and substituted ammonium salt Particularly preferred is monooctane phosphonic acid.
The amount of the sulphonate-type hydrotrope used in the present invention is 10 from 0 75-8 5 % by weight of the composition, and the amount of monoalkane phosphonic acid is from 0 5-2 5 %, preferably 1-2 % by weight of the composition, with the proviso that in the case of sodium xylene sulphonate more than 4 % thereof should be used if the amount of monoalkane phosphonic acid is 1 % or less The hydrotrope system provides for better stability, clarity and homogeneity when 15 included in aqueous built liquid detergent compositions, i e compositions containing an active synthetic detergent composition and an inorganic builder salt.
Such builder salts include the sodium or potassium ortho-, pyro and polyphosphates, and sodium or potassium carbonates, and mixtures thereof.
The benefit of the invention is particularly achieved in aqueous liquid 20 detergent composition which contain alkali metal carbonates such as sodium or potassium carbonate as the builder salt The amount of the inorganic builder salt present in such liquids may vary from 1-25 % by weight, and preferably lies between 5 and 15 % by weight.
In carbonate-built liquid detergents it is useful to include a polyelectrolyte to 25 prevent undesired incrustation or soil redeposition Such polyelectrolytes are e g.
polyacrylates, copolymers of ethylene with maleic anhydride or copolymers of maleic anhydride with vinylmethylether Particularly preferred are polyacrylic acids with a molecular weight of between 3,500-22,000 The amount of polyelectrolyte used varies from 0 5-5 %, preferably from 1-3 % by weight 30 The liquid detergent compositions furthermore comprise a ternary system of detergent active material, i e an anionic + a nonionic + a soap The anionic synthetic detergent active may be an alkylaryl sulphonate with 10-24 carbon atoms in the alkyl chain, an alkane sulphonate with 10-24 carbon atoms in the alkane chain, or alkylether sulphates with 10-24 carbon atoms in the alkyl chain 35 and from 1-10 moles of an alkylene oxide such as ethylene oxide and/or propylene oxide The nonionic synthetic detergents may be adducts of 5-30 moles of an alkylene oxide to a C,0-C 24 primary or secondary alcohol, and to a C,-C, 8 alkylphenol The soap is an alkali metal, ammonium or substituted ammonium salt of a C 10-C 24 fatty acid or polymers thereof The anionic synthetic detergent is 40 preferably a C,0-C 24 alkylbenzene sulphonate (as alkali metal, e g sodium or potassium, ammonium or substituted ammonium salt), the nonionic is preferably an ethoxylated linear C 8-C 22 alcohol condensed with 3 to 25 moles of ethylene oxide and the soap is preferably a sodium or potassium, ammonium or substituted ammonium salt of a polymeric fatty acid, predominantly consisting of dimerized 45 oleic acid The amounts of the anionic, nonionic and soap may vary from 515, 1-5 and 1-5 %, respectively.
The compositions may furthermore comprise the usual ingredients such as silicates, borates, phosphates, fluorescers, soil-suspending agents, lather controllers or lather boosters, perfumes, germicides, enzymes, opacifiers, antiredeposition 50 agents, and so on.
The invention will now be further illustrated by the following Examples.
Example 1.
A liquid detergent formulation was prepared from the following ingredients % by weight 55 dodecylbenzene sulphonic acid 6 5 dimerized oleic acid 5 C,3-Cs primary alcohol, condensed with 11 moles of ethylene oxide 2 7 1,576,412 % by weight polyacrylic acid (MW 3,500-5,000) 2.0 0.15 SCMC (low viscosity) sodium silicate potassium hydroxide potassium carbonate sodium xylene sulphonate ( 40 7 % active) monooctane phosphonic acid ( 100 % active) water x y q.s 100.
First a premix of the potassium hydroxide, the dodecylbenzene sulphonic acid, the dimerized oleic acid, and the C,3-C,5 primary alcohol condensed with 11 moles of ethylene oxide was prepared, to which subsequently the remaining ingredients were added under agitation, and without heating The amount of sodium xylene sulphonate (x) and monooctane phosphonic acid (y) were varied in a series of experiments, and the physical characteristics of the liquids obtained were assessed The following results were obtained:
Storage temperature: room temperature % monooctane phosphonic 1 2 3 acid = y % sodium xylene O O O sulphonate = x Physical characteristics 2 liquid phases 1 liquid and 1 liquid and of liquid detergent 1 solid phase 1 solid phase composition Storage temperature: A: room temperature B: -4 C % sodium xylene sulphonate ( 40 7 % 12 14 16 18 20 22 active material) = x % monooctane phosphonic acid = y 0 0 0 0 0 0 Physical characteristics of liquid detergent A two liquid phases homogeneous clear liquid compo S i tion B two liquid phases homogeneous crystal clear liquid formation Storage temperature: A: room temperature B: -4 C 1,576,412 % sodium xylene sulphonate 7 8 10 12 14 ( 40 7 % active material = x % monooctane phosphonic 1 1 1 1 1 acid = y Physical characteristics two liquid clear, homogeneous of liquid detergent A phases liquid composition ,, B id id.
This example shows that monooctane phosphonic acid alone did not produce a clear, homogeneous liquid, and that only with 18-20 % sodium xylene sulphonate ( 40 7 % active material) alone a clear, homogeneous liquid both at room temperature and at -4 C could be obtained The combination of these two hydrotropes with e g 10 % sodium xylene sulphonate ( 40 7 % active material) and 1 % monooctane phosphonic acid produced already a clear, homogeneous liquid, i.e a reduction of the sodium xylene sulphonate by almost 50 %o could be obtained.
Example II.
0 In the same manner as in Example I the following composition was prepared.
% by weight dodecylbenzene sulphonic acid C,3-Cs primary alcohol, condensed with 11 moles of ethylene oxide dimerized oleic acid potassium hydroxide potassium carbonate alkaline silicate polyacrylic acid (M W 3,500-5,000) SCMC (low viscosity) fluorescers sodium xylene sulphonate (SXS) ( 100 % active) monooctane phosphonic acid (MOP) ( 100 % active) colouring agent, perfume and water q s.
The following storage stabilities were assessed:

Replacing potassium carbonate by sodium carbonate in Example I produces similar results, as does replacing sodium xylene sulphonate by sodium toluene or cumene sulphonate.
Example IV 5
The following two built liquid detergents were prepared:
% by weight A B potassium dodecylbenzene sulphonic acid 6 4 7 2 dimerized oleic acid 5 67 5 9 Ci 3-C 1 S primary alcohol, condensed with 11 moles of ethylene oxide 2 65 0 77 C,6-C 20 linear primary alcohol, condensed with moles of ethylene oxide 1 35 sodium tripolyphosphate 11 65 potassium carbonate 7 0 3 9 potassium orthophosphate 1 95 sodium silicate (Si O 2:Na 2 O2) 4 3 2 9 potassium hydroxide (to neutralize the dimerized oleic acid) 1 8 0 7 sodium xylene sulphonate ( 40 7 % active) x x sodium toluene sulphonate ( 45 % active) y y monooctane phosphonic acid ( 100 % active) z z potassium polyacrylate 2 0 0 49 sodium carboxymethylcellulose 0 15 water q s q s.
Varying amounts of x, y and z were used (x = 0-30 %, y = 0-30 %, z = 0-3 %), and the liquids were stored at room temperature, and at changing temperatures (-4 C and room temperature) 5 times, each for 48 hours The products were 10 assessed for clarity, homogeneity and stability, they being found satisfactory if the liquid was clear and homogeneous, or, in the case of the changing temperatures, if there were crystals which rapidly dissolved again or when there was only a temporary cloudiness.
The following results were obtained: I 5 Liquid A was satisfactory when x = 10 20 %o z 1 % or y = 2-l O % z = 2 %.
1,576,412 6 1,576,412 6 Liquid B was satisfactory when x = 12-14 % z= 1 % or x = 2-10 % z= 2 % or y = 10-12 % z= 1 % or y= 2-6 % z = 2 %.
In all other cases, using x or y or z alone much more was needed to obtain satisfactory liquids, e g for liquid A either x = 22-30 % or z = 3 % was needed, and 10 with y alone no clear liquid was obtained at all For liquid B, neither x alone nor y alone nor z alone produced a clear liquid.
