Definitions
- This application relates to heavy duty laundry detergent compositions. More particularly, it relates to such compositions, and to wash waters in which they or their components are present, that contain a nonionic detergent as the principal detersive component, a builder for the nonionic detergent and a scavenging clay, such as bentonite, which sorbs any dye released into the wash water from colored laundry and, due to the presence of the nonionic detergent in such wash water, prevents such sorbed dye from coloring any white or lighter colored laundry items that may be present in the wash water. Also within the invention are processes for manufacturing the described compositions and for using them and components thereof to wash mixed colored and light or uncolored laundry, without dye transfer between laundry items.
- a nonionic detergent as the principal detersive component
- a builder for the nonionic detergent and a scavenging clay, such as bentonite, which sorbs any dye released into the wash water from colored laundry and, due to the presence of the nonionic detergent in such wash water, prevents such sorbed dye
- a heavy duty laundry detergent composition of reduced dye transfer properties and of improved dye stability during laundering of mixed colored and white fabric laundry items comprises 4 to 20% of nonionic detergent, 5 to 30% of clay, 20 to 80% of builder for the nonionic detergent, 0 to 3% of polyvinyl pyrrolidone (PVP), essentially no per-compound and essentially no optical brightener, with any balance of the composition being selected from the group consisting of fillers, functional adjuvants and water, and mixtures thereof.
- the compositions are particulate, certain nonionic detergents and bentonite are employed and the components of the composition are present within certain preferred ranges of percentages.
- the invention is also of processes of manufacturing and of using such compositions, and of employing the components of the compositions in wash waters.
- the nonionic detergent of the invented compositions is preferably an ethoxylated higher alcohol, wherein "higher” means of 8 to 18 carbon atoms. More preferably, such alcohol is saturated and essentially straight chain, and is of 10 to 16 carbon atoms. Still more preferably it is of 11 to 15 carbon atoms and most preferably it is of 13 to 14 carbon atoms.
- essentially straight chain it is meant that the percentage of straight chain members of the group is over 60 and preferably over 70, and the remaining isomers are only slightly branched, such as with methyl or other lower alkyl (such as ethyl and propyl) branching at the 2-carbon and sometimes also at the 3-carbon. Preferably any such branching is at the 2-carbon and is methyl branching.
- the described alcohols are normally homologous mixtures, so when a range is given or a compound is named it will normally be a mixture of such compounds averaging in the range or averaging at the compound carbon content mentioned.
- pure straight chain alcohols may be employed, too, of chain lengths equal to the averages previously mentioned.
- the extent of ethoxylation is an average within the range of 3 to 12, preferably 5 to 10 and more preferably 7 to 9 moles, e.g., 7 to 9 moles per mole of the alcohol (or of other reactant that can produce the same or equivalent final nonionic detergent).
- nonionic detergent(s) can be substituted, preferably only in minor part (less than half the nonionic detergent content and preferably less than 20% thereof).
- nonionic detergents that may be employed those are preferred which are reaction or condensation products of ethylene oxide and a suitable lipophile or lipophilic material.
- Other members of the class of nonionic detergents such as higher fatty acid esters of ethylene oxide-based alcohols, may also be employed.
- both broad range ethoxyl distribution (BRE) and narrow range ethoxyl distribution (NRE) are useful, with the NRE compounds often being preferred.
- the ethoxylated alcohols that are useful include Tergitol® 24-L-60N, (a NRE) and Dobanol® 25 7EO (a BRE).
- Other suitable nonionic detergents are described in the McCutcheon's Detergent and Emulsifiers Annuals , such as that for 1981.
- the present detergent compositions are preferably ones which contain only nonionic detergent(s), to the exclusion of other types of detergents, or contain essentially no other detergents than those which are nonionic, relatively small proportions of other types of such nonnonionic detergents may be present without such compositions being outside this invention.
- the percentage of such non-nonionic detergents should be minor, with respect to the total detergent content, being less than 30% thereof for the total of amphoteric, ampholytic, zwitterionic, anionic and cationic detergents, preferably being less than 10%, more preferably less than 5% and most preferably 0%. It is considered that when such nonnonionic detergent content is less than 5% (or up to 5%) of the total synthetic organic detergent content the composition is "essentially free" of such anionic and other non-nonionic detergents.
- anionic detergents When such relatively small percentages of anionic detergents are present they will usually be C12 ⁇ 18 alcohol sulfates, C12 ⁇ 15 linear alkyl benzene sulfonates, C12 ⁇ 18 olefin sulfonates, C13 ⁇ 15 paraffin sulfonates or C12 ⁇ 18 alcohol polyethoxy sulfate of 1 to 20 ethoxy groups, or mixtures thereof, usually as sodium or other alkali metal salts. Listings of other types of detergents may be found in the McCutcheon texts mentioned previously.
- the clays that scavenge the dyes released from colored laundry are either swellable or non-swellable smectite clays of the montmorillonite type and of these bentonite has been found to be an excellent component of the present detergent compositions. While it would be expected that to sorb dyes from aqueous media it would be desirable to employ a swellable bentonite, such as a sodium or potassium bentonite, it has been found that calcium bentonite and other non-swellable bentonites can also be used, providing that there is a source of sodium (or potassium or other "swelling" cation) present in the wash water, which apparently converts the bentonite to swelling type.
- a swellable bentonite such as a sodium or potassium bentonite
- calcium bentonite and other non-swellable bentonites can also be used, providing that there is a source of sodium (or potassium or other "swelling" cation) present in the wash water,
- the sodium of the sulfate polyphosphate, carbonate, silicate and any other sources thereof apparently suffices to convert the bentonite to suitable swelling form and makes it capable of sorbing the released dyes from the wash water (which sorption is most often considered to be adsorption)
- the bentonite employed may be in powder form, having a particle size distribution that may be in the range of 44 to 125 microns, for example, or may be of other suitable size(s). Also, it may be agglomerated to desired size, such as in the range of sizes of the desired finished detergent composition particles.
- the bentonites employed may be those mined in the United States, such as Wyoming bentonite, which is a swellable sodium bentonite, or may be obtained from European sources, such as deposits located in Italy or Spain, which are usually calcium bentonites.
- the calcium bentonite may be treated before incorporation into the present compositions, as by reaction with sodium carbonate, to convert it to a swellable (or gelling) form, if desired, or may be added to the other components of the present compositions in non-swelling form. If used as calcium bentonite it will be desirable for the detergent composition to contain at least 1% and preferably 2 to 8%, of the bentonite weight of ionizable sodium, usua ly in the builder salt(s) present. Further descriptions of bentonites that are useful in the present invention may be found in U.S. patent applications S.N's. 07/755,965 and 07/756,030, hereby incorporated herein by reference.
- polyvinyl pyrrolidone When polyvinyl pyrrolidone (PVP) is present in the invented compositions it will very preferably be of a relatively low molecular weight, such as one in the range of 20,000 to 70,000, more preferably 30,000 to 50,000 and most preferably 40,000, e.g., 40,000 ⁇ 4,000.
- the molecular weights given are those obtained by gel permea tion chromatography or ultrafiltration through a membrane.
- copolymers of vinyl pyrrolidone and other monomers may be employed provided that they promote the reduction of dye transfer in washing in the manner of the homopolymer.
- monomers may be mentioned acrylonitrile and maleic anhydride.
- the molecular weights of any such copolymers should be in the ranges given for the homopolymer.
- the builder in the present heavy duty detergent compositions is often preferably a water soluble polyphosphate.
- a water soluble polyphosphate may be employed, at least in part, as builders, the water soluble polyphosphates which are sodium salts are highly preferred builders and of these the tripolyphosphates, especially pentasodium tripolyphosphate, are most preferred.
- Such polyphosphates are preferably humidified (to avoid overheating due to hydration when mixed with water in the crutcher before spray drying). The humidification of detergent grade polyphosphates is well known, and need not be described further here. However, anhydrous or hydrated polyphosphates may also be employed.
- phosphates In detergent compositions in which phosphates are not to be present, or in which their presence is to be limited, sometimes due to governmental regulations, they may be replaced by carbonates, silicates bicarbonates, borates, zeolites and other inorganic (preferred) and organic builders, in which cases it is more desirable, although not necessary, to incorporate PVP into the formula for improved inhibition of dye transfer (because the dispersing phosphate is omitted).
- the other builders than polyphosphate builder may include both water soluble and water insoluble builders. Of the latter class the most prominent are the zeolites, which have water softening properties, such as anhydrous or hydrated Zeolite 4A.
- Water soluble organic builders may include: citrates, such as sodium citrate; nitrilotriacetates, such as trisodium nitrilotriacetate; polycarboxylates; and polyacetal carboxylates.
- the water soluble inorganic builders which usually are prefer red, include alkali metal carbonates, alkali metal silicates, alkali metal bicarbonates and alkali metal borates, and such include also the alkali metal sesquisilicates and alkali metal sesquicarbonates. Of the alkali metal salts the sodium salts are usually much preferred.
- the sodium silicate is preferably one in which the ratio of Na2O:SiO2 is in the range of 1:1.6 to 1:2.4, more preferably 1:1.8 to 1:2.2 and most preferably 1:2 or about 1:2.
- Preferred principal builders which will usually be 50% or more of the builder content of the compositions, will usually be a polyphosphate, such as sodium tripolyphosphate, for phosphate-containing compositions, or a zeolite, such as Zeolite A, for non-phosphate compositions, but sodium carbonate may also be employ ed as such principal builder in non-phosphate compositions.
- the nonionic detergent acts to prevent or inhibit deposition of the bentonite (and scavenged dye) from the wash water onto surfaces of the washed laundry (including light colored or white cotton laundry on which such deposited color would be readily apparent and objectionable), so it is evident that other detergents that do not have such capability or which promote deposition, such as the anionic detergents should not be present (or if present should preferably be of limited concentration which does not result in noticeable dye transfer, e.g., less than 5 or 10% of the total detergent content, or less than 2 or 3% of the composition).
- the detergent content be all nonionic and of the type previously described, a higher linear saturated alcohol condensed with ethylene oxide, and that no anionic detergent be present in the invented compositions.
- clays than bentonite may be present with the bentonite, such as other hydrated aluminum silicates of the kaolinite, attapulgite, montmorillonite, illite, hectorite and halloysite types but normally such clay content will be relatively minor with respect to the bentonite content, e.g., under 1/2 or 1/4 of such content.
- the important considerations in selecting such a clay are its scavenging properties with respect to the dyes released from the laundry and its non-deposition onto the laundry in the wash water, when the invented compositions containing it are employed.
- the functional components include various materials that are intended to improve the detergent composition functionally, as distinguished from aesthetically.
- the anti-redeposition agents such as carboxymethyl cellulose (CMC), preferably the sodium salt, which act to maintain in wash water suspension the various soils removed from the laundry during washing, and prevent such soils from redepositing on the laundry.
- CMC and other anti-redeposition agents also help to inhibit deposition of bentonite and other clays, as well as clayey soils, onto laundry fabrics, and thereby assist in reducing dye transfer to light colored or white laundry.
- Enzymes act as additional agents that selectively help to decompose and remove different types of soils from laundry, thus aiding in cleaning.
- proteolytic enzymes for removing proteinaceous soils
- amylolytic enzymes for removing starchy soils
- lipolytic enzymes lipolytic enzymes (lipases) for removing fatty or oily soils
- cellulolytic enzymes for modifying cellulosic surfaces of laundry items to promote removal of soils from such surfaces.
- Anti-foaming agents act to control foaming in the crutcher and in the washing machine.
- the compounds employed for this purpose are compounds of silicon, such as silicones.
- Such compounds are usually silicone or siloxane polymers, such as methyl silicones, including dimethyl silicones, and polysiloxanes.
- PAE's Phosphoric acid esters
- esters of phosphoric acid are partial or complete esters of phosphoric acid, with the esterifying alcohol being a higher alcohol, preferably a higher saturated fatty alcohol, of 12 to 20 carbon atoms (on the average), more preferably a saturated fatty alcohol of 15 to 18 carbon atoms and most preferably of an average of 17 to 18 carbon atoms.
- the ester is preferably a monoester and/or a diester and more preferably is a mixture of monoester and diester, in approximately equal proportions (35 to 65% of one and 65 to 35% of the other) or in the 1:3 to 3:1 range.
- the C18 alcohol content will often preferably be greater than the C16 alcohol content, causing the average alcohol carbon content to be in the C17 to C18 range, despite the presence of some lower alcohols too.
- Polyacrylates and other polymers may be present in the detergent compositions to help to control bead characteristics of the spray dried base beads and also may have desirable building effects.
- the aesthetic adjuvants comprise perfumes and colorants, and the colorants include dyes and pigments.
- perfumes will almost always be present in the invented compositions colorants may be omitted. When they are present the nonionic detergent-clay combination will help to prevent discoloration of light or white laundry by them, too.
- compositions within the present invention without spray drying, in which case the normal crutcher mix components, less water (except water of hydration) may be dry mixed with dry components before application of the liquid state nonionic detergent to such mix and before perfuming.
- per-compounds such as sodium perborate
- bleach, ing materials should be omitted from the present compositions or the compositions should be essentially free of them, to limit the extent of dye removal from the laundry.
- optical brighteners, fluorescent dyes and other ultraviolet ray-to-visible light changers should be omitted from the invented detergent compositions or the compositions should be essentially free of them, for a similar reason.
- the small proportions present in such cases do not significantly adversely affect the colors of the fabrics of the items being laundered.
- the content of per-compound will be less than or up to 2% and more preferably less than or up to 1% (most preferably 0%) and the corresponding contents for the optical brightener will be 0.05%, 0.02% and 0%, respectively.
- the detergent composition comprises 4 to 20% of the nonionic detergent, 5 to 30% of clay and 20 to 80% of polyphosphate builder, with 0 to 3% of PVP as an optional component, and with any balance being selected from the group consisting of other builders for the nonionic detergent, fillers, functional components (which include non-nonionic detergents), aesthetic adjuvants and mixtures thereof.
- a preferred phosphate-containing composition within the invention comprises 10 to 20% of ethoxylated alcohol nonionic detergent, 15 to 30% of bentonite, 25 to 40% of sodium tripolyphosphate, 0 to 3% of PVP, 0 to 10% of sodium silicate, 0 to 20% of sodium carbonate, 0.3 to 2% of enzyme(s), 0.1 to 1% of PAE, 0.001 to 0.05% of silicone, 0 to 30% of sodium sulfate and 3 to 15% of water.
- Percentages given herein for the silicone and for the related anti-foam silicone compounds are actual percentages of the active component, although the silicones are usually marketed as solutions or suspensions in aqueous media.
- the percentages of enzyme are given on an "as supplied" basis because enzymes are so marketed. However, the enzymatic activities are measurable and provide a better measure of the enzymatic actions.
- Savinase® 4T a proteolytic enzyme obtained from Novo Industri, has an activity of 4 KNPU/g, minimum, and their Termamyl® 60T, an amylolytic enzyme, has an alpha-amylase activity of 60 KNU/g, minimum, and the ranges of enzyme contents may be restated accordingly.
- compositions within the invention comprise 10 to 20% of the nonionic detergent, 20 to 30% of the bentonite, 27 to 37% of the sodium tripolyphosphate, 0 to 3% of PVP, 3 to 10% of sodium silicate, 3 to 10% of sodium carbonate, 1 to 2% of enzymes, 0.3 to 0.9% of PAE mixture, 0.001 to 0.01% of silicone, 1 to 5% of sodium sulfate, 0.5 to 2% of carboxymethyl cellulose, 0.2 to 1% of perfume and 5 to 12% of water.
- PVP percentages are, in the order given, 15, 24, 32, 1.5, 7, 6.5, 1.5, 0.6, 0.002, 2.8, 1.2, 0.4 and 7.5, respectively.
- compositions because the silicone is supplied as a 10% active material, there is also present 0.018% of carrier for it, which carrier may be mostly water. Also, it is intended that each of such percentages given may be prefaced with "about” to indicate that it is not necessary for the exact percentage to be employed to make the composition one that is "most preferred”.
- non-phosphate built detergent compositions may be made which may include one or more non-phosphate builders, such as water insoluble zeolite and water soluble non-phosphate(s).
- non-phosphate builders such as water insoluble zeolite and water soluble non-phosphate(s).
- the proportions of nonionic detergent, clay (bentonite), builder and PVP are also 4 to 20, 5 to 30, 20 to 80 and 0 to 3.
- compositions of such type include 4 to 20% of nonionic detergent (NRE or BRE), 8 to 25% of clay, 10 to 30% of zeolite 5 to 20% of sodium carbonate, 0 to 10% of sodium silicate, 0 to 7% of sodium citrate, 0.3 to 2% of enzyme(s), 0.001 to 0.05% of silicone, and 1 to 15% of water.
- compositions comprise 5 to 15% of ethoxylated alcohol nonionic detergent (NRE or BRE) wherein the alcohol is linear and of 12 to 15 carbon atoms and is ethoxylated with 5 to 9 moles of ethylene oxide per mole, 15 to 25% of zeolite A, 7 to 13% of sodium carbonate, 0 to 5% of sodium silicate, 1 to 5% of sodium citrate, 0.3 to 1% of proteolytic enzyme, 0.01 to 0.05% of dimethyl silicone, 0.3 to 3% of sodium carboxymethyl cellulose, 0.5 to 3% of a copolymer of acrylic acid and maleic anhydride of a molecular weight in the range of 30,000 to 100,000, 0.2 to 1% of poly phosphonate chelating agent, 0 to 30% of sodium sulfate and 5 to 10% of water.
- NRE or BRE ethoxylated alcohol nonionic detergent
- the proportions of sodium sulfate and water may be varied and can be outside the ranges given without detri mentally
- non-carbonate inorganic builders from an aqueous crutcher mix, mix them with other particulate or powdered components, including carbonate, bicarbonate and/or sesquicarbonate, if present, in a tumbling drum mixer and spray or drip liquid state nonionic detergent into the tumbling mix, followed by application of perfume to the resulting product, preferably also by spraying.
- a desired well mixed particulate product which may be characterized as homogeneous.
- up to 2% (composition basis) of the nonionic detergent may be included in the crutcher mix/(without causing tower pluming).
- the crutcher mix has a solids content in the range of 40 to 60%, the balance being water, and is sprayed through nozzles (Type 5/5) into a concurrent spray drying tower in which the inlet air temperature is in the range of 200 to 400°C, preferably 200 to 300°C, and the outlet temperature is in the range of 70 to 100°C.
- the crutcher mix will be pumpable, and for crutcher mixes including sodium tripolyphosphate as the principal builder, solids contents in the lower part of the 40 to 60% range, e.g., 40%, will be practicable, whereas for non-phosphate crutcher mixes, e.g., those based on zeolite builder, solids contents in the upper part of the range, e.g., 60%, are feasible, as are lower solids contents.
- the spray dried beads resulting usually containing from 10 to 20% of water, are of particle sizes in the range of 0.1 to 2 mm in diameter and are of bulk densities in the range of 0.5 to 0.8 g/cc.
- the base beads so made are then mixed in a tumbling drum type of mixer (although other types of mixers may also be employed) until all the dry components, including the bentonite and carbonate, are well dispersed in the base beads, and then the nonionic detergent, in liquid state and at a temperature in the range of 25 to 60°C, is sprayed or dripped onto the moving mix.
- the nonionic detergent serves to help bind the mix components together, especially upon solidification at a lower temperature, and some of it permeates the particles of product and helps to disperse such particles in the wash water, in such capacity helping the bentonite and the polyphosphate, when present, to act as dispersants, too.
- Perfume is then applied to the composition at a temperature that is preferably room temperature or thereabout (20 to 30°C) but which is no higher than 40°C.
- the final particulate product is of particle sizes in the 0.1 to 2 mm diameter range and of a bulk density in the range of 0.6 to 0.8 g/cc.
- liquid compositions may be made, as may be gels, usually with the various components being in the same proportions as in the particulate compositions and with the water contents thereof being in the range of 12 to 75%, with co-solvents, such as ethanol and isopropanol sometimes being present, too, replacing some of the water, e.g., 1/10 to 1/2 thereof.
- the particulate or powdered compositions may also be made without spray drying of the base beads, by mixing in the polyphosphate or zeolite, silicate (in powder or solution form), sulfate and silicone (which can be omitted) with the clay and other powders, etc., in the dry mixer before application of the nonionic detergent thereto.
- the invented particulate compositions are employed in the same general manner as other detergent powders, with some variations in the procedure to minimize dye transfer and fading.
- the concentration of the composition in the wash water will be in the range of 0.05 to 1.5%, preferably 0.1 to 1%, more preferably 0.2 to 0.5%, and most preferably 0.3 to 0.4%, e.g., 0.35%, and the wash water temperature will usually be in the range of 10 to 95°C, preferably 10 to 60°C, more preferably 30 to 45°C and most preferably 40°C or about 40°C.
- Washing machines utilized will very preferably be of the horizontal tumbler type, with a side opening door.
- the nonionic detergent formula is particularly suited to this type of washing because it does not generate as much foam as do anionic detergent formulas.
- the washing cycle will last from 30 to 120 minutes, including rinsings, and the cycle will normally include at least three rinsings (to remove all the clay with sorbed dye on it) after pumping out of the wash water, and thereby dye transfer to the washed light colored laundry will be prevented.
- the form of the detergent composition is different from particulate or powdered, such as liquid or gel, or of the various components, separately or in sub-combinations, the charge thereof to the wash water in the washing machine will be such as to make the wash water of equivalent concentrations of the various components, compared to the particulate product's charge thereof.
- the amounts thereof charged will preferably be in the following ranges: 0.018 to 0.065% of nonionic detergent; 0.015 to 0.1% of clay, 0.065 to 0.22% of builder and 0 to 0.019% of PVP, with the preferred ranges of concentrations of the other components that may be present being similarly proportional to their percentages in the particulate products, e.g., 0.001 to 0.01% of CMC.
- the detergent compositions of this invention effectively wash soiled laundry when employed in washing machine washings of such laundry in the concentrations described, and inhibit dye transfer better than commercial products on the market that are advocated as not causing dye transfers between dark colored laundry items and light colored or white laundry items. They also are found to be mild to colored laundry items and do not cause fading of colors thereof, as may occur when other detergent compositions containing the normal proportions of perborate are employed. Yet, they wash the laundry clean and, in fact, are even superior to some commercial detergents in removing soils and stains, such as greasy and particulate soils and red wine stains, from laundry. It has been found by plicants that essential omission of optical brighteners from the detergent composition is of importance in preventing color hue change during the washing of colored laundry.
- the invented detergent compositions effectively wash mixed charges of colored and uncolored laundry without causing objectionable fading of the colored items and without objectionable dye transfer from the colored items to those that were uncolored or lightly colored.
- the color purging action of the present compositions appears to be a rather complex physical phenomenon in which the bentonite adsorbs any dye released from colored laundry and carries it out of the washing machine tub with the wash and rinse waters.
- the bentonite does not exert any fabric softening effects, indicating that it and the adsorbed dye are not deposited on and retained by the washed laundry. Color measurements confirm such findings.
- a particulate heavy duty built nonionic detergent composition of the above formula is made by spray drying a 47% solids content crutcher mix of the tripolyphosphate, silicate (as a 40% aqueous solution), sulfate and silicone through three type 5/5 nozzles into a concurrent spray drying tower, in which the inlet drying air temperature is in the range of 200 to 275°C and the outlet air temperature is in the range of 76 to 95°C.
- the crutcher mix is satisfactorily deaerated, due at least in part to the presence therein of the silicone.
- the spray dried beads resulting are of a moisture content of 16% ⁇ 2%, of particle sizes in the range of 0.1 to 2 mm in diameter, and of a bulk density in the range of 0.5 to 0.8 g/cc.
- the beads are of rounded shapes and satisfactory strength, so as to be able to resist breakage during mixing operations.
- the spray dried beads are then mixed with the sodium carbonate, enzymes, CMC, PAE and bentonite in a rotary drum mixer and after thorough mixing of the added components with the base beads there is sprayed onto the moving surfaces of the mix the liquid state nonionic detergent, at a temperature of about 55°C (its flow temperature being about 30°C).
- the heavy duty laundry detergent composition made is then tested for detergency, dye transfer properties and fading effects by standardized testing procedures.
- detergency it is tested in an automatic washing machine of the horizontal drum, side door type, against a variety of standard soils on a variety of test fabrics, including cottons and synthetics, as well as blends thereof, and is found to be equal to or better than a commercial detergent composition, being especially effective against mixed greasy/particulate soils and red wine stains.
- Dye transfer characteristics are measured by testing against a control, which is a commercial product that is marketed as one which allows washing of colored and white goods together without objectionable dye transfer from the colored items to the white ones.
- control has been analyzed and has been found to include 9% of linear alkylbenzene sulfonate, 2% of lauryl ethoxylate sulfate, 5% of nonionic detergent, 32% of zeolite, 21% of sodium citrate (as the dihydrate) and the balance of adjuvants, filler and water.
- Color stability tests are run in essentially the same manner as the dye transfer tests except that the white towels are omitted from the wash load, being replaced by additional colored towels (or cloths), and the control is changed to a laboratory version of a commercial detergent formula that contains perborate and optical brightener.
- control formula includes 16% of applicants' nonionic detergent, 0.6% of their PAE, 3.5% of their silicate, 25% of their tripolyphosphate, 19.8% of zeolite, 1.2% of CMC, 1% of their enzymes, 20% of sodium perborate tetrahydrate, 0.4% of stilbene optical brightener, 2% of copolymer salts (Sokalan® and the balance of water and sodium sulfate (preferably 8% of water and 2.5% of the sulfate).
- the dried cloths are evaluated comparatively for color losses and it is found, both by machine measurements and by human panel evaluations, that the experimental formula results in significantly less color fading from those cloths dyed with bleach sensitive dyes than when the formula employed is the "commercial" detergent composition.
- the experimental formula contains 1.5% or 3% of PVP of the type mentioned herein the color fading is also decreased.
- the same concentration of detergent composition 0.33%, the same water temperature, 40°C, and the same other washing equipment and conditions are employed.
- the particulate built detergent composition of this example is made in the same manner as that described in Example 1 and the product resulting, which is of the same particle size range and bulk density, is tested for detergency, dye transfer characteristics and color stability in controlled laboratory tests. It is found to be a good detergent, of less dye transfer action than the dye transfer control formula described in Example 1, and of greater color stability than the color stability control formula described in Example 1.
- the PVP of Example 1 is incorporated in the formula to the extent of 1.5% and 3% (being post-added) an improvement in dye transfer inhibition is obtained and when the CMC is omitted dye transfer increases result.
- the PVP is added in the crutcher little difference in dye transfer is noted, compared to when it is post-added.
- the proportions of the other components of the formula are adjusted proportionally.
- the proportion of sodium sulfate (filler) may be changed accordingly, keeping the percentages of other components the same.
- the invented detergent composition of this formula is made in the same manner as described previously for Examples 1 and 2.
- the PVP is added in the crutcher and no silicone is present (as in Example 2).
- the particulate detergent composition resulting is of particle size range and bulk density like the compositions of Examples 1 and 2 and is of good detergent properties. It does not cause objectionable color fading, by the tests described previously, and dye transfer during washing is inhibited, so that the product is unobjectionable to users thereof and is considered to be essentially non-transferring of dyes from colored to uncolored laundry.
- NRE Tergitol 24-L-60N replaces the BRE and a very effective detergent composition of low dye transfer property results.
- Nonionic detergent Dobanol 25 7EO
- Polyphosphonate chelating compound (Dequest® 2041) 0.44 Sodium citrate 3.0 Sodalan® CP5 (copolymer of acrylic acid and maleic anhydride of molecular weight of about 70,000) 1.1 Sodium carboxymethyl cellulose 1.0
- Proteolytic enzyme Savinase®, mf'd. by Novo Industri
- This non-phosphate built detergent composition is made by essentially the same procedure as was described previously in Example 1, with the crutcher slurry including the zeolite, sulfate, polyphosphonate, silicone, sodium citrate and water, and with such mix being spray dried to a moisture content of about 11%, after which it is mixed with the remaining components except for the nonionic detergent, which is post sprayed onto the mix while in liquid state.
- the resulting unperfumed product when tested in the manner previously described for detergency, dye transfer resistance and fading resistance, is found to be significantly better than a control in which the bentonite is replaced by sodium sulfate (as a filler), in dye transfer resistance.
- the control includes a usual bleaching proportion of a perborate or other per-compound the experimental product is significantly better than the control in fading resistance. It is also the equivalent of the first control product in cleaning power.
- nonionic detergent present in the formulas the more effective it is in promoting better cleaning and better resistance to dye transfers.
- up to 3% of sodium perborate or other per-compound and/or up to 0.1% of optical brightener or fluorescent dye are in the invented compositions (when such compositions are essentially free of such materials) the washed laundry appears to be cleaner and brighter and the dye transfer effects are not significantly different from those when such materials are omitted entirely.
- the builder may include 10% of Zeolite A and 16% of sodium tripolyphosphate as the main builder combination with the sodium sulfate content being decreased to 22.045% to compensate.
- perfumes will usually be present, normally up to 1 or 2% thereof, often in replacement of the sulfate filler, and the cleaning power and dye transfer resistance will be essentially the same as for the products that do not contain perfume.
- detergent compositions are obtained that are at least equivalent in detergency to controls, and do not cause objectionable dye transfers or color fadings.
- the compositions described are superior in dye transfer inhibiting and color stability to many commercial detergent products, even to those that have been marketed as especially good for dye transfer inhibition and color stability properties.
- liquid state products can be made by diluting the particulate compositions with water, and adding an emulsifier and/or a solvent when that is considered to be desirable. By adding water (sometimes with an organic solvent) and a gelling agent to the components of the particulate products one can make gel versions of the products.
- anionic detergents such as sodium linear tridecylbenzene sulfonate and lauryl alcohol ethoxylate sulfate (3 EtO per mole) or mixtures thereof are completely substituted for the nonionic detergent described herein dye transfer is increased, which is objectionable, and when per-compounds and/or optical brighteners are present in the described compositions in amounts greater than the limits previously given objectionable color fading or other color change occurs. Also, when bentonite is omitted dye transfers increase. Thus, such controls are inferior to the invented products.
- the particulate detergent composition formulas of the invention all contain significant proportions of detergent and builder, with little filler (sodium sulfate), and can be characterized as concentrated detergents. Therefore, lower wash water concentrations of such products are employed (near the lower ends of the ranges previously given) than of the usual detergent compositions. For example, whereas 0.85% of one typical commercial neavy duty built detergent composition might be employed according to European practice, often 0.35% of the invented concentrated product can suffice, with even less being employed when the water hardness is low (below 100 p.p.m., as CaCO3).
