Definitions
- the present invention relates to free- flowing particulate detergent compositions containing nonionic surfactants, and methods and apparatus for making such detergent compositions.
- the free-flowing compositions in particular relate to detergent compositions comprising carbonate and bicarbonate builders and from about 2 to 20 percent by total weight nonionic surfactant.
- the process comprises mixing raw materials, applying nonionic surfactant to the mixture, compacting the mixture, granulating the mixture, and then screening the mixture to produce a free-flowing detergent-
- the apparatus comprises means for mixing raw materials, means for applying nonionic surfactant to the surface of the mixture, means for compacting, means for granulating, and means for screening to produce free-flowing detergent.
- nonionic surfactants generally impart tacky qualities to the powder detergents, thereby inhibiting flowability.
- particulate detergent compositions comprising more than 2 percent by weight nonionic surfactant will tend not to flow out of a container freely, but will rather cake and then block the opening of the container.
- Granular detergents are generally produced by spray drying. Such processes involve slurring detergent components and then spray atomizing in a high temperature air stream. However, such processes are generally not satisfactory for detergents containing nonionic surfactants; nonionic surfactants are volatile so there would be an increase in the probability of fire or explosion.
- Greene U.S. Patent No. 4,473,485 attempts to overcome the flowability problems of high nonionic containing detergents with a chemical combination for use in wet agglomeration processes.
- Greene's approach has several drawbacks. For instance, alkali or alkaline earth metal carbonate raw materials must have a mean particle diameter of 20 microns or less. Also, the process of wet agglomeration is complicated and costly because water must be added to the detergent to dispense a structuring agent, and then the excess water must be removed.
- compositions, processes and apparatus of the prior art have not proven entirely satisfactory.
- Free-flowing detergents containing more than 2 percent nonionic surfactant generally must be agglomerated to achieve desired flow properties.
- Raw materials having small mean diameters must generally be utilized.
- the processes and apparatus to produce free-flowing detergents generally require difficult processing steps to produce, such as agglomeration and water removal.
- the process of the present invention for producing free-flowing, nonionic surfactant containing particulate detergent comprises (a) mixing raw materials to produce a raw material mixture; (b) applying to the raw material mixture nonionic surfactant to produce an intermediate mixture, wherein the amount of the nonionic surfactant is in the range of about 2-20% by weight of the total intermediate mixture; (c) compacting the intermediate mixture to produce a compacted mixture; and (d) granulating and screening the compacted mixture to produce free-flowing, nonionic surfactant containing particulate detergent.
- the raw materials utilized in the process will preferably comprise carbonate and bicarbonate builders, especially a mixture of sodium carbonate and sodium bicarbonate.
- Such raw materials may further comprise sodium sulfate and sodium silicate.
- the nonionic surfactant can be applied to the raw material by spraying, and said surfactant will preferably comprise alkoxylated linear alcohol.
- the intermediate mixture will preferably be compacted with a roll compactor.
- the compacted mixture can comprise cohesive sheets, pallets, or sticks.
- Another aspect of the present invention concerns a free-flowing, nonionic surfactant containing particulate detergent which can be produced by the above-referenced process of the present invention.
- the detergent can comprise (a) carbonate and bicarbonate builders; and (b) nonionic surfactant.
- the detergent can comprise from about 2 to 20 percent by total weight nonionic surfactant, and the detergent composition can be compacted and granulated so that it has a bulk density of 0.7-1.3 g/cc; a mean particle diameter of about 200-2,000 microns; and a flowability factor (discussed below) of not more than 7.
- the free-flowing detergent can further comprise sodium sulfate and sodium silicate.
- the detergent will preferably have a mean bulk density of from about 0.8-1.20 g/cc.
- the detergent will comprise about 1-12 weight percent sodium bicarbonate; about 10-40 weight percent sodium carbonate; about 4-18 weight percent sodium silicate; about 1-12 weight percent polyacrylate polymer blend; about 2-6 weight percent alkoxylated linear alcohol; and about 10-65 weight percent sodium sulfate.
- the apparatus can comprise (a) means for mixing raw materials to produce a raw material mixture; (b) means for applying nonionic surfactant to the raw material mixture to produce an intermediate mixture; (c) means for compacting the intermediate mixture to produce a compacted mixture; (d) means for granulating the compacted mixture to produce granules; and (e) means for screening the granules; wherein said apparatus is capable of producing a free-flowing detergent powder comprising from 2 to 20 percent by weight nonionic surfactant.
- the means for applying nonionic surfactant can be a sprayer, and the means for compacting can be a roll press.
- FIG. l is a view of an apparatus used to determine the flowability of the present invention. This drawing is for illustrative purposes only and should not be used to unduly limit the scope of the invention.
- the raw materials are first premixed. Soda ash, bicarbonate salt, sodium sulfate, sodium silicate, polymers and bleach are introduced to a blender and then mixed. Nonionic surfactant is sprayed onto the powder materials in the blender. After the desired amount of nonionic surfactant has been sprayed onto the raw material mixture, the resulting nonionic containing mixture (intermediate mixture) is fed into a compactor to produce cohesive sheet, pallets, or sticks. The cohesive sheets, pallets or sticks are fed to a granulator to produce detergent particles. The particles are fed through a screening system which separates oversized and undersized particles. Oversized and undersized particles are returned to the compactor.
- Perfume is added to the free-flowing detergent particles.
- the final detergent flows to a surge bin, and then to packing.
- Mixing may be performed by any suitable mixing device, such as a rotating drum, ribbon blender or any other vessel with suitable means for mixing. Methods of mixing are well-known to those skilled in the art. Mixing may be performed by either a continuous or batch operation.
- the mixer may be adapted so that liquid nonionic surfactant can be sprayed onto base particles in the blender.
- Especially preferred for mixing is a ribbon blender.
- the nonionic surfactant will be distributed on the raw materials during the mixing operation.
- Surfactant is preferably applied by spraying, such as by means of an atomizing nozzle of conventional type.
- Especially preferred for applying nonionic surfactant are air atomizing nozzles by Spraying Systems Co.
- Compacting may be performed by applying pressure to the intermediate mixture of raw materials and nonionic surfactant. It may be performed by continuously admitting the intermediate mixture to a zone wherein the intermediate mixture is subjected to pressure between two rolls running oppositely with respect to each other.
- a preferred means of compacting is by a roll compactor wherein the intermediate mixture is subjected to pressure between two rolls under an adjustable compacting pressure.
- An especially preferred compactor is the Fitzpatrick Company "CHILSONATER" compactor. The gap between rolls and the amount of intermediate mixture introduced to such a roll compactor can be adjusted to produce cohesive detergent sheets, pallets, or sticks.
- Granulating can be performed by any suitable granulating or crushing means.
- the compacted sheets, pallets, or sticks may be crushed to a desired particle size distribution.
- the compacted sheets, pallets, or sticks are fed through a sieve crusher to force the compacted mixture through a sieve with meshes of a given size determining the particle size of the final product.
- a preferred means for granulating is a FITZMILL manufactured by the Fitzpatrick Company.
- Screening can be performed by any suitable screening device. Crushed material may be screened to separate oversized and undersized particles in conventional oscillating sieves- The oversized and undersized particles may be recycled into the compacter to be re-compacted
