Definitions
- the invention relates to the manufacture of high density, free flowing agglomerated detergent granules, using a liquid binding agent and zeolite X as a flow aid.
- detergent granules having relatively high bulk density, e.g. 600 g/liter and above.
- detergent granules which comprise organic surfactant and inorganic or organic builders are prepared by spray drying an aqueous slurry of the components.
- the granules thus obtained typically have a density of from about 300 to about 500 g/liter.
- various processes have been developed for providing such products.
- Pat 5,133,924, Appel et al, issued July 28 1992 discloses a process wherein a spray-dried detergent composition or a mixture of particulate components of a detergent composition is subjected to a two-stage mixing process in order to reduce the porosity of the particles, thereby increasing density.
- Liquids, such as water or nonionic surfactants are optionally added to the second stage mixer.
- Application 61-69897 published April 10, 1986 discloses a process for producing a dense agglomerated detergent product from spray dried detergent granules comprising a surfactant and builder, wherein the granules are pulverized by vigorous stirring in a blade mixer, followed by mixing with a binder (e.g., nonionic surfactant) and a "surface improving agent", which can be an aluminosilicate.
- a binder e.g., nonionic surfactant
- a surface improving agent which can be an aluminosilicate.
- the present invention is directed to a process of forming agglomerated detergent compositions comprising the steps of;
- Step (b) contacting the mixture formed in Step (a) with Zeolite X, wherein the amount of Zeolite X is at least equal to, and preferably from 1 to about 2.5 times, the weight amount of liquid binder in Step (a).
- the present invention also encompasses the composition of the above process.
- the present invention relates to the preparation of agglomerated detergent granules wherein granular detergent material is mixed with a limited amount of a liquid binder material, thereby resulting in agglomerates having an increased particle size compared to the original detergent granules.
- agglomerates formed in this manner often tend to be sticky, and therefore have poor free-flow properties.
- Zeolite X is a particularly effective free-flow aid when applied as a surface coating to said agglomerates.
- Zeolite A is also effective as a free-flow aid and has generally been preferred over Zeolite X for most detergent uses because of its better sequestering power
- Zeolite X is a more effective free-flow aid than Zeolite A for detergent agglomerates utilizing liquid binders.
- the use of Zeolite X as free-flow aid in said agglomerates results in a higher density product than obtained when using Zeolite A.
- the products produced by the process herein have a bulk density of greater than 600 grams/liter.
- the granular detergent composition in Step (a) of the process of the present invention comprises a detersive surfactant.
- the surfactant and any other components of the granular compositions can be introduced into Step (a) as separate ingredients or as a pre-formed composition, such as a spray dried detergent composition or as a mixture of one or more separate granular ingredients and a spray dried detergent composition.
- Anionic surfactants are the preferred surfactants for use herein and are well known in the art. The following are representative examples of such surfactants.
- Anionic surfactants suitable for use herein include the water-soluble salts, preferably the alkali metal, ammonium and alkylolammonium salts, of organic sulfuric reaction products having in their molecular structure an alkyl group containing from about 10 to about 20 carbon atoms and a sulfonic acid or sulfuric acid ester group.
- alkyl is the alkyl portion of acyl groups.
- this group of synthetic surfactants are the sodium and potassium alkyl sulfates, especially those obtained by sulfating the higher (C ⁇ .jg carbon atoms) primary or secondary alcohols such as those produced by reducing the glycerides of tallow or coconut oil or by the oxo process; and the sodium and potassium alkylbenzene sulfonates in which the alkyl group contains from about 9 to about 15 carbon atoms, in straight chain or branched chain configuration, e.g., those of the type described in U.S. Patents 2,220,099 and 2,477,383, incorporated herein by reference.
- linear straight chain alkylbenzene sulfonates in which the average number of carbon atoms in the alkyl group is from about 1 1 to 13.
- anionic surfactants suitable for use herein are the sodium alkyl glyceryl ether sulfonates, especially those ethers of higher alcohols derived from tallow and coconut oil; sodium coconut oil fatty acid monoglyceride sulfonates and sulfates; sodium or potassium salts of sulfuric acid esters of the reaction product of one mole of a fatty alcohol (e.g.
- coconut or tallow alcohol with 1 to 6 moles of ethylene oxide; sodium or potassium salts of alkyl phenol ethylene oxide ether sulfates having about 1 to 10 units of ethylene oxide per molecule and in which the alkyl radicals contain about 8 to 12 carbon atoms.
- suitable anionic surfactants include the water-soluble salts of esters of alpha-sulfonated fatty acids containing from about 6 to 20 carbon atoms in the fatty acid group and from about 1 to 10 carbon atoms in the ester group; water-soluble salts of 2-acyloxyalkane- 1 -sulfonic acids containing from about 2 to 9 carbon atoms in the acyl group and from 9 to about 23 carbon atoms in the alkane moiety; water-soluble salts of olefin and paraffin sulfonates containing from about 12 to 20 carbon atoms; and beta-alkyloxy alkane sulfonates containing from about 1 to 3 carbon atoms in the alkyl group and from about 8 to 20 carbon atoms in the alkane moiety.
- Preferred anionic surfactants are the alkali metal salts of C JO-18 » n ear alkylbenzene sulfonate and C i o- 18 a M sulfate.
- a preferred embodiment of the present invention is wherein the anionic surfactant comprises from about 20% to about 40% of a mixture of sodium C IQ- B linear alkylbenzene sulfonate and sodium C12-I6 alkyl sulfate in a weight ratio of about 2: 1 to 1 :2.
- Water-soluble salts of the higher fatty acids are also useful anionic surfactants in the compositions herein.
- Soaps can be made by direct saponification of fats and oils or by the neutralization of free fatty acids.
- Particularly useful are the sodium and potassium salts of the mixtures of fatty acids derived from coconut oil and tallow, i.e., sodium or potassium tallow and coconut soap.
- surfactants suitable for use in the granular detergent compositions of step (a) includes nonionic, cationic ampholytic, and zwitterionic types.
- nonionic surfactants include the alkylene oxide condensates of hydrocarbyl groups (e.g. alkyl or alkyl phenyl) wherein the hydrocarbyl groups contain from about 8 to about 22 carbon atoms.
- Nonionics also include semi polar compounds such as C8-C22 amine oxides.

- Z preferably will be derived from a reducing sugar in a reductive amination reaction; more preferably Z is a glycityl moiety.

These corn syrups may yield a mix of sugar components for Z. It should be understood that it is by no means intended to exclude other suitable raw materials.
