The composition is particularly useful in 'softening-through-the-wash' products. The clay flocculating polymer is sieved or ground such that at least 95 % by weight of the clay flocculating polymer has a particle size of less than 250 micrometers, and preferably less than 150 micrometers, before adding it to the granular detergent composition.

Description

Comprise the detergent composition of particle size less than 250 microns clay flocculating polymer
The present invention relates to granular detergent composition, it contains (i) mild clay and (ii) clay flocculating polymer, also relates to the preparation method for compositions.Composition is particularly useful for the product of " soft in washing process ".
Clay flocculating polymer, for example the high-molecular weight polyethylene oxide can commerce buy with 100% reactive powder.
On January 18th, 1989, disclosed EP-A-0299575 disclosed granular detergent composition, and it comprises mild clay and polymer/clay flocculating polymer.Its explanation, in preparation granular detergent composition process, the polymer/clay flocculation agent can add in every way.It can be added in the crutcher mixture before spraying drying; Or as the spray solution of water or organic solvent on granulated detergent; Or with particulate form and granulated detergent dry blending.This application is not mentioned the grain sizes of clay flocculating polymer.
Yet, do when mixing when polymer/clay flocculating polymer and granulated detergent, observe undesirable uneven clay deposition or residual.Inhomogeneous deposition is meant the visible piece of the clay that is deposited on the fabric face.This causes because clay particle before clay dispersion flocculates rapidly.This causes being deposited on the formation of the clay block on the fabric face.When residual the because high local concentrations that is present in the clay flocculating polymer in the prescription contact with water the formation gel causes, this causes the product bad dispersibility and has increased product and be deposited on risk on the fabric.
In addition, clay flocculating polymer can produce operation and blast problem when operating with particle form.
Summary of the invention
According to the present invention, before in joining granular detergent composition, make that by screening or grinding clay flocculating polymer at least 95% clay flocculating polymer has less than 250 microns by weight, preferably less than 150 microns particle size, thereby avoided undesirable inhomogeneous clay deposition and residual.
Clay flocculating polymer preferably molecular-weight average is 100,000 to 10,000,000, more preferably 150,000 to 800,000 polyethylene oxide.
In another aspect of this invention, the method for preparing granular detergent composition is provided, it comprise with clay flocculating polymer be selected from the powder pre-mixing of silico-aluminate, silicate, carbonate, Citrate trianion, phosphoric acid salt or their mixture and subsequently with premixture and other detergent component blended step.
Premixture is that 1: 20 to 20: 1 clay flocculating polymer and silico-aluminate formed by ratio preferably.The detailed description mild clay of invention
Mild clay can be unmodified or organically-modified.Not organically-modified clay can be described as expandable three layers of clay, i.e. silico-aluminate and Magnesium Silicate q-agent, and the ion-exchange capacity of clay is at least the 50meq/100g clay, preferably is at least the 60meq/100g clay.The initial clay that is used for organo-clay can be described similarly.Be used to describe clay term " expandable when contacting with water with bedded clay structure swelling or expansible ability relevant.Three layers of swellable clay that the present invention uses are the materials that is categorized as terre verte on the geology.Have two kinds of dissimilar smectite-type clay, it broadly can be distinguished according to the silicon-Sauerstoffatom number that octahedral metal-oxygen is arranged in central core for given number in skin.Clay mineral is more complete is described in " clay colloid chemistry ", H.van Olphen, John Wiley; Sons (IntersciencePublishers), New York, 1963, chapter 6 especially provides in the 66-69 page or leaf.
Terre verte (or smectites) clay series comprises following trioctahedron mineral substance: talcum; Hectorite; Talcum powder; Sauconite; Vermiculite; With following dioctahedron mineral substance: prophyllite; Montmorillonite; Volchonskonite; And nontronite.
The clay that uses in these compositions contains cation counterbalancing ion, for example, and proton, sodium ion, potassium ion, calcium ion and lithium ion.People distinguish clay according to positively charged ion mainly a kind of or absorption exclusively usually.For example the sodium clay is that the positively charged ion that wherein adsorbs mainly is the clay of sodium.The positively charged ion of this absorption can carry out permutoid reaction with the positively charged ion that is present in the aqueous solution.The typical exchange reaction that contains smectite-type clay is represented by following reaction formula:
Smectic clays (Na) ++ NH 4OH=＞smectic clays (NH 4) ++ NaOH is because in the balanced reaction in front, etc. the sodium of the weight such as ammonium ion replacement of weight, people measure cation exchange capacity (CEC) (being sometimes referred to as " alkali exchange capacity ") with the milligramequivalents (meq/100g) of per 100 gram clays usually.The cation exchange capacity (CEC) of clay can Several Methods be measured, comprise electrophoretic method, exchange then by titration or by the methylene blue method with ammonium, all these methods are in Grimshaw " chemistry of clay and physics ", 264-265 page or leaf, intactly explanation among the Interscience (19-1).The cation exchange capacity (CEC) of clay material is relevant with the inflatable character of factor such as clay, the electric charge of clay (it is determined by crystalline network again at least in part) etc.For some smectic clays, the ion-exchange capacity of clay can be in the extensive variation to about 150meq/100g and the bigger scope of about 2meq/100g kaolin.
Preferred smectite-type clay is sodium montmorillonite, potassium montmorillonite, sodium hectorite and potassium hectorite.The clay that the present invention uses has up to about 1 micron particle size.
Any clay that the present invention uses can naturally or synthetic obtain.Clay flocculating polymer
Most of clay flocculating polymers are quite long long chain polymer and the multipolymers that obtained by monomer such as oxyethane, acrylamide, vinylformic acid, dimethylaminoethyl methacrylate, vinyl alcohol, vinyl pyrrolidone and ethylene imine.Glue also is suitable as guar gum.
Preferably oxyethane, acrylamide or polymerizing acrylic acid thing.If their molecular weight of these polymkeric substance is in 100000 to 10000000 scope then improve the deposition of fabric sofetening clay significantly.Preferably weight-average molecular weight is 150000 to 5000000 polymkeric substance:
Most preferred polymkeric substance is poly-(oxyethane).Molecular weight distribution can use poly-(oxyethane) standard of gel permeation chromatography contrast narrow molecular weight distributions easily to measure.Method
The particle size of polymkeric substance reduces by the normal abrasive operation or by the screening of particulate physics.Randomly with raw material and powder, for example thin silico-aluminate (zeolite A) mixes in mixing tank, joins then in the finished product operation then.Zeolite works as the carrier of polymkeric substance, helps its dispersion in the finished product preparation.
Can use the particle size of many types change equipment with the average particle size particle size that reduces clay flocculating polymer to being lower than 250 microns.Continuous sieve apparatus, for example Russel Finex and Mogenson Vibrationsifter extension set or scraping sieve apparatus continuously.The screening operation at intermittence that comprises the RoTap variable also can be used for a spot of situation.For fairly large operation, can use continuous air spray shredder, it can make scantling reduce and classification simultaneously.
