Definitions
- the invention relates to preparation of aqueous detergent slurries with reduced viscosity. This invention also relates to preparation of " a particulate detergent and the novel detergent composition.
- Particulate detergent compositions are generally prepared by forming an aqueous slurry of the materials which form the deter ⁇ gent and drying the slurry.
- the slurry of the detergent forming composition is generally formed in a apparatus called a crutcher. Since the water present 1n the slurry must be removed to form a particulate detergent, the slurry generally has as low a con ⁇ centration of water as permitted by the required handling of the slurry in the drying operation.
- Detergent compositions generally comprise at least one sur- factant, detergent builders such as phosphates, maleic acid/vinyl ether copolymers, silicates, carbonates, salts of nitrilotriacetic acid, zeolites and the like, fillers such as sodium sulfate, sodium chloride and various additives which prevent redeposition, brighten the clothes, chelate metal ions and the like.
- detergent builders such as phosphates, maleic acid/vinyl ether copolymers, silicates, carbonates, salts of nitrilotriacetic acid, zeolites and the like
- fillers such as sodium sulfate, sodium chloride and various additives which prevent redeposition, brighten the clothes, chelate metal ions and the like.
- patent 4,536,319 which is incorporated herein by reference discloses detergent compositions containing alkyl polyglycoside surfactant and a co-surfactant.
- alkyl polyglycoside surfactant and a co-surfactant.
- One of the detergent builders which has been substituted for the now banned phosphates is sodium carbonate.
- the inclusion of alkyl polyglycosides alone in a carbonate built detergent composition does not have the effect of substantially reducing the viscosity of the slurry. Accordingly, slurries containing higher propor ⁇ tions of water are required so that the detergent slurry can be handled and transported to the drying apparatus. The inclusion of the additional water in the detergent slurry reduces the capacity of the drying apparatus and increases the cost of preparing the particulate detergent composition.
- the viscosity of a carbonate containing and particularly a carbonate built detergent slurry can be substantially reduced by including in the detergent slurry composition a viscosity reducing amount of an alkyl polyglycoside and an alkali metal chloride.
- the viscosity of a detergent slurry containing a zeolite can also be reduced by addi ⁇ tion of alkyl polyglycoside and an alkali metal chloride to the detergent slurry.
- the process for preparing a particulate detergent composition of the present invention comprises forming an aqueous slurry com- prising per 100 parts of total slurry weight:
- the non-aqueous composition comprises: a. from about 2% to 50% by weight of an anionic surfac- tant, a nonionic surfactant or mixture thereof; b. from about 10% to about 70% by weight of an alkali metal carbonate builder; c. from about 0 to about 50% by weight of at least one supplemental builder; d. from about 0 to about 60% by weight of at least one filler; e. from about 0 to about 15% by weight of at least one additive; f. at least a viscosity reducing amount of at least one alkyl glycoside and an alkali metal chloride;
- the invention also includes a slurry having the above com ⁇ position and a particulate detergent formed from the dried slurry.
- the slurry is preferably dried by spray drying.
- Fig. 1 is a bar graph illustrating a comparison of the viscosity of carbonate built detergent slurries containing alkali metal chlorides, alkyl polyglycoside and a mixture of alkali metal chloride and alkyl polyglucoside.
- Fig. 2 1s a bar graph illustrating the effect of alkali metal chloride and alkyl polyglucosides of varying compositions on the viscosity of a carbonate built detergent slurry.
- Fig. 3 is bar graph illustrating the effectiveness of alkali metal chloride and alkyl polyglucoside on the viscosity of a car ⁇ bonate built detergent slurry containing an anionic and nonionic surfactant.
- Fig. 4 is a bar graph illustrating the effect of alkali metal chloride and alkyl polyglucoside on the viscosity of a carbonate built detergent slurry containing a nonionic surfactant.
- U.S. Patent 4,675,127 discloses that the addition of alkyl polyglycoside to a detergent slurry containing a phosphate builder substantially reduces the viscosity of the slurry.
- the amount of water in the slurry can be reduced to form a slurry with a higher concentration of active ingredients having a viscosity which still permits handling of the detergent slurry with normal handling equipment. That is, the addition of more non-aqueous materials to the alkyl polyglycoside containing slurry produces a slurry with a viscosity and pu pability not higher than a slurry of lower con- centration not containing the alkyl polyglycoside.
- alkyl polyglucoside alone does not substantially reduce the viscosity of carbonate containing detergent slurries.
- Applicants have unexpectedly discovered that the combination of alkyl glycoside and particularly an alkyl polyglycoside and an alkali metal chloride substantially reduces the viscosity of car ⁇ bonate containing and particularly carbonate built detergent slurries.
- the discovery is unexpected since the addition of either alkyl glycoside or an alkali metal chloride salt alone to a carbonate containing detergent slurry does not substantially reduce the viscosity of the slurry and, in some cases, actually increases the viscosity.
- the phrase "carbonate built" detergent slurry refers to a slurry wherein a major portion of the builder 1s an alkali metal carbonate, bicarbonate, sesquicarbonate or mix ⁇ ture thereof.
- the Inclusion of alkyl glycoside and the alkali metal chloride in the carbonate built or carbonate containing detergent slurry also stabilizes the slurry so that the viscosity of the slurry does not substantially increase over the period of time between the detergent slurry preparation and transfer to the drying apparatus.
- the viscosity of a detergent slurry increases as the detergent slurry ages. This is particularly cri ⁇ tical in low water slurries. Low water slurries as they age and the ingredients hydrate- tend to become granular and can set up as a solid material.
- the addition of alkyl glycoside and alkali metal chloride to the detergent slurries of the invention permits the slurry to remain fluid over long periods of time. Even when the viscosity of the carbonate containing slurry does not require reduction, the addition of alkyl glycoside and preferably alkyl polyglycoside and alkali metal chloride improves the texture and handleability of the slurry.
- the present invention precludes such an occurrence.
- the present invention can be practiced as an emergency measure wherein a mixture of alkyl glycoside and alkali metal chloride can be introduced into the slurry and mixed therewith to pre ⁇ vent the slurry from setting-up during a plant emergency.
- the addition of alkyl glycoside and the alkali metal chloride to a detergent composition containing a nonionic surfactant can aid in homogenizing the slurry and preventing separating out or oiling out of the nonionic surfactant.
- detergent slurries are prepared at an elevated temperature 1n a range of about 130 to about 175°F.
- the solubility of nonionic surfactants generally decreases as the temperature Increases.
- the nonionic surfac ⁇ tants if present in substantial quantities, tend to separate from the detergent slurry and form a discontinuous or oily phase.
- the 5 addition of alkyl glycoside and the alkali metal chloride aid in dispersing the nonionic surfactant throughout the detergent slurry.
- the non-aqueous portion of the detergent slurry of the pre ⁇ sent invention comprises from 2 to 50% by weight of an anionic
- the surfactant is present at from about 8 to about 25% by weight and more preferably from about 10 to 20% by weight.

- builder ingredients include alkali metal citrates, alkali metal silicates, alkali metal nitrilotriacetates, carboxymethyl- oxy-succinates, zeolites and the like.
- additional builders are present at from 15-40% by weight.
- the composition of the present invention can contain minor amounts of phosphate builders. However, inclusion of more than 20% by weight of the non-aqueous portion of the composition of a phosphate builder can unduly increase the viscosity of the slurry.
- the present inven ⁇ tion is useful for reducing the viscosity of slurries containing a major portion of a zeolite builder containing a carbonate builder.

- Alkyl glycosides containing Z substituents and their method of preparation are disclosed in United States Application Serial No. 86,990 filed August 19, 1987, which is incorporated herein by reference.
- R is generally the residue of a fatty alcohol having from about 8-30 and preferably 8-18 carbon atoms.

- the alkylpolyglycosides can contain a glycosal moiety which is selected from group consisting of fructose, glucose, anose, galactose, talose, gulose, allose, altose, itose, aribanose, xylose, luxose, ribose and mixtures thereof.
- a glycosal moiety which is selected from group consisting of fructose, glucose, anose, galactose, talose, gulose, allose, altose, itose, aribanose, xylose, luxose, ribose and mixtures thereof.
- the glyco ⁇ sal moiety is a glucose moiety.
- a viscosity reducing amount of the alkylglycoside generally ranges from 0.5 to 10% by weight of the non-aqueous portion of the detergent composition.
- detergent compositions containing more than 10% of the alkylglycoside are also encompassed within the present invention.
- the alkylglycoside is a surfactant per se and can be utilized in higher amounts.
- suitable viscosity reduction can generally be obtained in the range from about 0.5 to about 8% by weight.
- the alkylglycoside is an alkyl polyglycoside and most preferably an alkyl polyglucoside.
- the alkali metal chloride salts when used with the alkylgly- cosides in the practice of the present invention substantially reduce the viscosity of the aqueous detergent slurry composition of the present invention.

- the alkali metal chloride is sodium chloride, potassium chloride or mixtures thereof.
- the alkylglycoside and the alkali metal chloride salt in the detergent composition can reduce the water content of the slurry up to 30% or more without a significant increase in the viscosity of the slurry.
- Reduction in the water content of the slurry results in a conco - itta ⁇ t increase in the throughput of the drying apparatus since a substantial portion of the thermal load of a drying apparatus is utilized to provide the latent heat of vaporization for the water which is removed from the detergent slurry to form the particulate detergent composition.
- the preferred method of drying is spray drying which is well known in the art and will not be further described here.
- the higher solids content also tends to produce a dried detergent having a higher bulk density.
- the higher bulk density permits packaging the detergent in smaller packages and, there ⁇ fore, reduces packaging and shipping costs.
- the discovery of the present invention is unexpected since neither the alkylglycoside nor the alkali metal chloride alone have a substantial viscosity reducing effect on the detergent slurry of the invention. Only the combination of the alkylglycoside and the alkali metal chloride substantially reduces the viscosity of the detergent slurry composition.
- the detergent slurry compositions with the reduced viscosity are prepared by adding the surfactants, the alkylglycoside, the alkali metal chloride and any other liquid or minor amounts of dry ingredients to the water for forming the slurry.
- the water con ⁇ taining the materials is agitated, and the dry ingredients which are to be added in major proportions are mixed with the aqueous portion. It takes a short period of mixing, generally from 5 to 25 minutes, to form a slurry with a generally stable viscosity.
- the viscosity of the detergent slurry can vary.
- the slurries were prepared in a 600 ml tall form beaker using 420 to 470 g of non-aqueous ingredi ⁇ ents.
- a LIGHTNIN® mixer having a single, three blade stirrer (2 inches in diameter) positioned one half inch from the bottom of the beaker was used for mixing.
- the mixer was attached to a Variac® power control unit so that the mixing could be done at the highest possible speed without entraining air into the slurry. Air causes the slurry viscosity to increase.
- the beaker was placed in a constant temperature water cir- culating bath maintained at 160°F. Water was introduced into the beaker, and the surfactants, silicates, alkyl glycosides and alkali metal chloride along with any additives were mixed with the water. The sodium carbonate and any other builders and fillers were then added to the aqueous mixture in the beaker over a 10 minute period. The maximum mixing speed was attained before all the ingredients were added. The maximum mixer speed was about 2000 rpm as measured by a strobe light.
- the stirring at the maximum mixing speed was continued for 5 minutes after all dry ingredients had been added.
- the viscosity was measured after the slurry had set for 10 minutes.
- the slurry was then mixed for an additional 20 minutes, and a second visco ⁇ sity taken.
- Some slurries were mixed for a second 20 minute period and some were permitted to sit for 16 hours at 160°F, then stirred and the viscosity measured. Since the viscosity was relatively stable and did not change significantly after the first 20 minute mixing period, the viscosities reported are shown as the 5 minute and the 25 minute mixing periods.
- the viscosities of the slurry were measured by an RVT model viscosimeter mounted on a Brookfield Helipath Stand.
- the Brookfield Helipath Stand slowly lowers the viscosimeter into the slurry so that the rotating shearing spindle describes a helical path through the test sample.
- the readings were taken in the bot ⁇ tom half of the slurry to minimize the effect of mixture lost or crust formation on the top of the slurry. A minimum of ten readings were taken on average to get a representative viscosity.
- the experiment reported in Fig. 1 was done to determine the effect of sodium chloride, potassium chloride, alkyl polyglu ⁇ coside and a mixture of alkyl polyglucoside and sodium chloride and alkyl polyglucoside and potassium chloride on the viscosity of a slurry.

- a slurry was prepared first with no additives having the com ⁇ position shown under Control.
- a second slurry was prepared substituting 5% of sodium chloride for 5% of the sodium sulfate in the formulation.
- a second formulation wherein 5% of potassium chloride was substituted for 5% of the sodium sulfate in the for ⁇ mulation.
- a fourth formulation was prepared in which 2% APG® 500 was substituted for 2% of the sodium sulfate in the formulation.
- a fifth formulation was prepared in which 2% APG® 500 and 5% sodium chloride were substituted for 7% of the sodium sulfate in the composition.
- a sixth formulation was prepared wherein 2% APG® and 5% potassium chloride was substituted for 7% of the sodium sulfate.
- slurries were prepared to determine the effect of alkyl chain length and degree of polymerization (DP) on the viscosity of a anionic detergent, carbonate built system con- taining 28% water.
- the slurry is noted as containing 72% solids by weight. The solids are the portion which remains after removal of water. Not all of the materials are necessarily solids but can be viscous liquids.
- the slurries were prepared as described above and the visco- sities measured after 25 minutes of stirring at 2000 rpm.
- the alkyl polyglycoside was of the formula RO-(R 1 0-) y G x wherein y was equal to 0, Z was a glucose residue and x is the degree of polymerization and R is an alkyl group having from 8 to 13 carbon atoms.
- Fig. 2 clearly shows that alkyl polyglucosides, over a broad composition range, when combined with an alkali metal chloride reduces the viscosity of a carbonate built detergent system.
- the example was carried out to show the reduction in visco ⁇ sity of an anionic/nonionic surfactant carbonate built detergent system by the incorporation therein of the APG ® alkyl polygluco ⁇ side and an alkali metal chloride.
- a control formulation and an equivalent formulation containing APG® were prepared.
- the for ⁇ mulations were as follows:
- Fig. 3 shows the viscosity of the control slurry containing 37.5% water and an APG and alkali metal chloride containing slurry containing 26% water. Even though the slurry containing APG ® and alkali metal chloride contained only 69% of the water in the control slurry, the visco- was only about 1/6 as high.
- the values for the viscosities shown in the bar graph were as follows:
- a slurry containing a substantially higher percentage of nonaqueous material could be processed with an increase in the efficiency of the drying apparatus.
- the lower viscosity would be advantageous in a spray drying process.
- the APG ® in the formulation aids in preventing the oiling out of the nonionic detergent.
- NaLAS sodium dodecylbe ⁇ zene sulfonate.
- LAE 25-7 is an ethoxylated primary alcohol nonionic surfac ⁇ tant sold under Trademark Neodol 25-7 from Shell Chemical Company.
- Example 4 The example illustrates the effect of APG® and potassium chloride on the viscosity of a nonionic surfactant, carbonate built detergent system.

- the results of the experi ⁇ ment are set forth in Fig. 4.
- the figure clearly shows that the combination of APG® and potassium chloride has a substantial effect on the viscosity of the aqueous detergent slurry.
- APG ® surfactant added to the nonionic detergent slurry composition helps in preventing the nonionic detergent from oiling out or separating from the slurry at the elevated tem ⁇ perature (160°F) used for preparing these slurries.
- the formulation utilized was as follows: Control APG
- APG® 225 refers to an alkylpolyglucoside with a 9-11 carbon alkyl group and x is 1.5-1.6.
- the other APG® materials were as set forth in example 2.
- Anionic Surfactant (dodecylbenzenesulfonate sodium salt) 15
- the effect of APG® and alkali metal chloride on the viscosity of slurries containing an anionic and nonionic surfactant and sodium carbonate was determined by preparing six slurries having a non-aqueous content of from 60.5 to 74%. Potassium chloride and APG® were added to these slurries and the viscosity of the slurries determined. The slurries were prepared according to the method set forth above. The composition of the slurry (dry solid) is shown in Table II. The results of the experiment are set forth in Table II. It can be seen from Table II that potassium chloride alone has a detrimental effect on the viscosity of the detergent slurry.
- Potassium chloride alone without APG® increased the viscosity of the slurry.
- the APG prevented oiling-out of the nonionic surfactant from the slurry composition.
- the prevention of the separation of nonionic surfactant from the detergent slurry is a valuable attribute of incorporation of the APG into the slurry composition.
- Anionic Surfactant (dodecylbenzenesulfonate) 12 sodium salt
- Nonionic Surfacant (Neodol 25-7) 12
- Typical detergent formulations which aqueous slurrys can be improved by the addition of small amounts of an alkali metal chloride and an APG® are as follows: Anionic surfactant 5-30% by weight Sodium carbonate 15-70% by weight Sodium sulfate 0-60% by weight Sodium chloride 0-25% by weight Sodium silicate 3-25% by weight Alkyl polyglucosides 0.5-10% by weight
- Anionic surfactant-nonionlc surfactant containing for- mulations are becoming more popular due to the attractive proper ⁇ ties of the anionic and nonionic surfactants when they are combined in a detergent.
- a detergent containing an anionic and a nonionic surfactant would be shown above with the addition of from about 3-15% of the nonionic surfactant. If an all- nonionic surfactant detergent is desired, the anionic surfactant can be replaced in the above formulation by about 3-15% of a nonionic surfactant.
- the addition of APG® and an alkali metal chloride to the composition if the composition does not already contain an alkali metal chloride will substantially reduce the viscosity of an aqueous slurry of the detergent.
- a typical anionic-nonionic formulation would be as follows:
- XP8E-A96 APG ® 500 made with C12-C13 alcohol (Neodol 23) and has an average DP of 1.3 - 1.4
