Definitions

  • the present invention relates to detergent compositions for washing and softening fabrics, comprising at least one detergent active material and a fabric softening bentonite clay.
  • the invention also relates to a process for producing the clay.
  • one such single detergent and softening composition is provided by including in the detergent composition a smectite clay containing material having a cation exchange capacity of at least 50 meq/lOOg, together with a detergent active material.
  • GB 2 138 037 discloses a fabric softening detergent in which a clay may be activated by inserting a monovalent metal into the clay structure.
  • Sodium and potassium are given as examples of the monovalent ion.
  • Clays of interest in the present invention are swelling types, which expand and delaminate in liquid media. These clays belong to the group of phyllosilicates and are three- layer sheet type crystalline materials.
  • the sheet structures are composed of three layer arrangements of tetrahedral silica, octahedral alumina, and tetrahedral silica.
  • the central layer may be dioctahedral or trioctahedral and the three layer sheet structures are separated by an interlamellar space.
  • Clays are defined as crystalline and amorphous hydrated silicates of Al, Mg Li and Fe. They comprise fine colloidal particles. The following key features distinguish the different varieties:
  • Point b offers the opportunity for a permanent charge on the lattice which must be balanced by cations present in close proximity.
  • M+ refers to the charge balancing cations introduced as a result of the isomorphic substitution.
  • the degree of isomorphic substitution determines the magnitude of the layer charge, a crucial factor in the swelling of clays.
  • the layer structure has many variants in nature.
  • the central octahedral layer may have the two aluminium ions (Al + ) (dioctahedral) replaced by three magnesium ions (Mg + ) (trioctahedral) or the octahedral layer may be partially occupied by the substitution of one Al 3+ for one Mg2+
  • a residual surplus of negative charge can also arise when silicon ions (Si 4+) in the tetrahedral layer are replaced by aluminium ions (Al ) .
  • the surplus of negative charge requires the presence of balancing cations which are located in the interlamellar space between the sheet- structures
  • a measure of the degree of the surplus charge is given by the number of exchangeable cations, as reflected by the cation exchange capacity CEC of the pure mineral.
  • the CEC of a mineral is directly related to the lattice charge deficiency of that mineral.
  • M 111 is a trivalent metal ion e.g. Al 3+ , Fe 3+ , Cr 3+
  • N 11 is a divalent metal ion e.g. Mg 2+ , Fe 2+ , Ni 2* , Zn 2*
  • L 11 is a univalent metal ion e.g. Li + y is zero or a positive number less than four a and b are separately or together zero or positive numbers.
  • CEC measurements indirectly determine the number of X n* y+b/n present in lOOg and quote these as meq.
  • Swelling is the process in which solvent molecules penetrate the inter layer space between individual crystals, and occurs very readily in clays containing exchangeable cations such as hectorites and montmorillonites.
  • the factors which most influence the swelling behaviour is aqueous suspension are:
  • Point i) is important because substitution in the tetrahedral layer creates a localised charge and in the octahedral layer a delocalised charge. The latter interacts only weakly with water molecules.
  • Clays used in through the wash fabric softening are generally montmorillonites. Although it has been shown that softening performance is a function of lattice charge, the detailed mechanism of the action of clays in fabric softening is not fully understood. Both delamination (swelling) behaviour, and electrostatic forces between the clay particles and the fabric substrate are thought to govern the overall process, and both are influenced by layer charge.
  • Montmorillonites occur in nature with a range of layer charges, and optimum softening is observed with a limited number of clays of poor colour which have layer charges at the lower end of the range.
  • the lattice charge of clays can however be modified by chemical treatment. Controlled incorporation of Li cations in the crystal lattice (by ion exchange/calcination) is described in EP 0 401 047 (Unilever) and leads to an improvement in the performance of the clay through charge reduction.
  • Layer charge reduction of montmorillonite requires neutralisation of a delocalised negative charge. This is thought to be achieved when Li cations penetrate the crystal lattice upon dehydration. They are thought to move into octahedral vacancies in the aluminous region of the montmorillonite lattice. This process requires an expensive calcination step to achieve the dehydration of the Li cation before penetration into the lattice can take place.
  • KC1 or KOH have been used as electrolytes in drilling fluids to stabilise montmorillonite or other smectite clays during boring operations.
  • Potassium is also a natural constituent of some natural bentonite clays at a level of up to 1% as K 2 0.
  • Potassium will also have been used with bentonite clay by virtue of it being present at a low level in sodium salts when prepared commercially.
  • the level of potassium would have been less than 1%, as K 2 0, of the total clay in this case.
  • Naturally occurring clays The number and availability of naturally occurring clays . is fairly limited. Such naturally occurring clays may be of unsuitable colour for inclusion in a detergent composition or may give rise to fabric colour dulling once deposited thereon. It is therefore desirable that a boosting of softening performance be achieved for lower performance naturally occurring clays of good colour, so that the range of clays that can be used for fabric softening is extended.
  • the present invention claims a detergent composition for washing and softening fabrics comprising at least one detergent active material, a fabric softening clay which is a bentonite clay and at least 1%, of the total formulation of a soluble potassium salt, expressed as K 2 0.
  • the present invention also claims a detergent composition for washing and softening fabrics comprising at least one detergent active material, and a potassium ion exchanged bentonite clay whereby the level of potassium in the clay is more than 1.5% expressed as K 2 0.
  • Such potassium treated clays have the advantage that they can be selected from a wide range of good colour parent clays.
  • Detergent compositions containing modified clays have the advantage that colour dulling associated with off colour clays may be avoided and improved softening can be obtained.
  • One aspect of the process of the present invention comprises the preparation of partially potassium exchanged clays. They may be prepared by mixing dry sodium clay with a solution containing potassium ions, typically KC1 solution to form a stiff dough. The dough is then subjected to high shear in a sigma blade mixer and then dried and crushed.
  • a solution containing potassium ions typically KC1 solution
  • They may also be prepared by spraying sodium clay with a potassium solution in a rotating drum, for example an agglomerating apparatus.
  • the clays may be prepared by:
  • the mixtures of sodium and potassium clay minerals are in the ratio range of 8:2 to 2:8 parts by weight. If ion exchange takes place in solution before the detergent is formulated then it is desirable to dry the clay.
  • the ratio of sodium to potassium in the exchanged clay is less than 2:1, preferably less than 1:1.
  • the source of potassium ions is provided by the partial or total replacement of a sodium salt normally present in the detergent composition, by the corresponding potassium salt. It is preferable if the corresponding potassium salt is present in a level greater than 2.5 wt% of the total composition, more preferably a level greater than 5 wt%, most preferably at a level greater than 7.5 wt%.
  • potassium carbonate may be included in the formulation in place of the usual sodium carbonate, a second example of this technique is the replacement of sodium citrate by potassium citrate.
  • Clay mineral containing materials useful in the present invention include dioctahedral and trioctahedral three layer smectite clays, ideally of the calcium and/or sodium montmorillonite type.
  • PRASSA clay from Greece, GELWHITE from Texas USA, Willemse from South Africa and VOLCLAY BC from Wyoming.
  • the effectiveness of a clay containing material as a fabric softener will depend partly on the level of clay mineral in the material.
  • the detergent compositions according to the present invention may take various physical forms and may contain a variety of additional ingredients.
  • An essential ingredient is a detergent active material. This may be selected from anionic, nonionic, amphoteric, zwitterionic and cationic materials, with a special preference for synthetic anionic surfactants, with or without nonionic surfactants.

  • the preferred detergent compounds which can be used are synthetic anionic and nonionic compounds.
  • the former are usually water-soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher acyl radicals.
  • suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher (C 8 -C 18 ) alcohols produced for example from tallow or coconut oil, sodium and potassium alkyl (C 9 -C 20 ) benzene sulphonates, particularly sodium linear secondary alkyl (C 10 -C 15 ) benzene sulphonates; sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived from tallow or coconut oil and synthetic alcohols derived from petroleum; sodium coconut oil fatty monoglyceride sulphates and sulphonates; sodium and potassium salts of sulphuric acid esters of higher (C e -C ⁇ e ) fatty alcohol-alkylene oxides, particularly ethylene oxide, reaction products; the reaction products of fatty acids such as coconut fatty acids esterified with isethionic acid and neutralised with sodium hydroxide; sodium and potassium salts of fatty acid amide
  • Suitable nonionic detergent compounds which may be used include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amide or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.
  • Specific nonionic detergent compounds are alkyl (C 6 -C 22 ) phenols-ethylene oxide condensates, generally up to 25 EO, i.e. up to 25 units of ethylene oxide per molecule, the condensation products of aliphatic (C 8 -C 18 ) primary or secondary linear or branched alcohols with ethylene oxide, generally up to 40 EO, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamine.
  • Other so-called nonionic detergent compounds include long chain tertiary amine oxides, long chain tertiary phosphine oxides and dialkyl sulphoxides.
  • detergent compounds for example mixed anionic or mixed anionic and nonionic compounds may be used in the detergent compositions, particularly in the latter case to provide controlled low sudsing properties. This is beneficial for compositions intended for use in suds- intolerant automatic washing machines.
  • Amounts of amphoteric or zwitterionic detergent compounds can also be used in the compositions of the invention but this is not normally desired due to their relatively high cost. If any amphoteric or zwitterionic detergent compounds are used it is generally in small amounts in compositions based on the much more commonly used synthetic anionic and/or nonionic detergent compounds.
  • a detergency builder may also be present. This may be any material capable of reducing the level of free calcium ions in the wash liquor and will preferably provide the composition with other beneficial properties such as the generation of an alkaline pH, the suspension of soil removed from the fabric and the suspension of the fabric softening clay material.

  • the clay material can be added in various physical forms. It may, for example, be spray-dried with other components of the formulation or it may be added separately.

  • Potassium ion exchanged clay and ammonium ion exchanged clay for comparative purposes were prepared by the following method.
  • the montmorillonite used was Prassa clay ex Colin Stewart Minerals.
  • Potassium acetate (anhydrous ex Sigma) was used without additional drying.
  • Ammonium, sodium and potassium salts were all ex BDH GPR and solutions of the required concentration were made up using Millipore water.
  • Montmorillonite (20g) was weighed into polythene pots containing 200 ml of a mixture of Na and K (or NH 4 ) chloride solutions (1.0M) . The relative proportions of Na and K were varied and the total ionic strength maintained. The pots were shaken thoroughly, and stored for one week with occasional further mixing during that time. The mixtures were centrifuged and washed as in example 1, then dried at approximately 100°C, ground finely, using a mortar and pestle and stored as in example 1.
  • Montmorillonite clays exchanged with K and NH 4 cations in accordance with example 1 were added at 0.5 g/L to a phosphate built washing powder and tested against a reference containing no clay and a control containing a Na- montmorillonite material.
  • the performance of all clays tested is superior to the zero clay reference, so they all show a softening banefit - see Table 3.
  • the NH 4 exchanged material shows an equivalent performance to the reference.
  • the K exchanged clay shows enhanced softening over all the compositions.
  • the phosphate formulation used for examples 3 and 4 was: Parts (wt)
  • Potassium fixation by montmorillonite can therefore be used to enhance the performance of clays for through the wash softening. Whilst not wishing to be bound by theory this enhancement is believed to be a result of an effective reduction of the clay lattice charge. Even though the K exchanged clay may need to be dried, overall the process is much more convenient than processes involving an expensive calcination step.
  • the clay in all cases was Na Montmorillonite (ex CSM) , added at 0.5 g/1.
  • Table 4 also records the results of washing experiments which indicate that the enhanced softening seen in the presence of potassium ions is as a result of enhanced clay deposition.
  • Example 5 was repeated using simulated wash liquors
  • Softening was monitored from sodium carbonate containing solutions of LAS:nonionic (0.83g/l approx. 9:1 LAS:NI) . Experiments using this system were also carried out in the presence and absence of zeolite (4A - 1.8g/l hydrated) .
  • Base composition is: 0.75 g/L LAS 0.08 g/L NI 1.20 g/L Na 2 CQ 3
  • This example shows the effect of added potassium on the softening performance of clay in a detergent system containing a linear alkyl sulphonate anionic and a nonionic detergent active in various ratios.
  • Table 7 shows that the performance enhancement due to use of potassium treated clay is greatest in the 100% anionic formulation. The effect was demonstrated by measurement of clay deposition levels (ash) . Mixtures of soap and nonionic actives show analogous behaviour.
  • potassium was added in the form of its chloride.
  • Potassium could be added in the form of carbonate, replacing sodium carbonate as a source of alkalinity.
