Description
Technical field
The present invention relates to a kind of method of producing cleaning composition.Specifically, the present invention relates to the method that a kind of production has the cleaning composition of medium or low bulk density, also relate to the cleaning composition of producing by this method.
Background of the present invention
Usually, cleaning composition is produced by spray drying process, wherein, the composition and the water of said composition are mixed into water mediation slurry, then this slurry is sprayed onto in the spray-drying tower, and contacts, anhydrate so that remove with warm air, thereby acquisition detergent particles, this particle are commonly referred to as " basis " powder.Thus obtained particle has highly porous.The powder of being produced has the tap density of 300-550g/l usually in this way, and this density reaches as high as 650g/l.
Spray-drying powder can produce good powder transportation performance usually, as good distribution and solubility property.But, the investment of spray-drying process and cost are higher.However, still have this low-density washing powder of a large amount of consumer wants.
In recent years, produced washing powder by the mechanically mixing method already with high-bulk-density.700-900g/l even higher tap density had been obtained already.Usually, this washing powder is produced like this: the spray-dired basic powder of densification in one or several mechanical mixer, optionally choose wantonly and add other composition, or mix the composition of described composition, and do not use the spraying drying step by continuous or batch mixed technology.
Powder with high-bulk-density and low packaging volume helps storing and distributing operation, uses but also help the human consumer.In addition, if do not use the spraying drying step, its investment and production cost usually can be lower, and such method also can make energy consumption reduction, thereby the benefit of environmental protection aspect is provided.Therefore, wish usually to avoid in the washing composition production technique, using spray drying technology.
But, described highdensity powder has the porosity lower than conventional spray-dried powders usually, and this can hinder this powder to carry in washing liq.In addition, up to now, under the prerequisite of not using the spraying drying step, also be not easy to realize having the production of low bulk density, for example make the tap density of this powder be lower than about 700g/l to medium tap density powder with commercial size.
EP-A-367 339 has disclosed the method that a kind of production has the cleaning composition of high-bulk-density, wherein, handle feed particulate material with super mixer, form or keep the yielding state of this mixture with a moderate-speed mixers, dry then and/or cool off.Described raw material can be a kind of spray-dired basic powder, maybe can use the composition of composition not carry out spraying drying step in advance in the washing composition production process.
Disclose (Unilever: the right of priority in the application is unexposed before the date) according to WO97/02338, if described composition is prepared with a kind of composition with low bulk density, can for example obtain to be lower than the low bulk density of 700g/l by the method for not using the spraying drying step.But, this method is not suitable for using the raw material of selling with the high density granular form comparatively speaking, or this material itself is produced (latter can produce the bigger particle of porosity usually) by spraying drying.
We have found that, can obtain the powder of medium or low bulk density by a kind of new method, this method is such: with a kind of powder and a kind of liquid component mechanically mixing that contains detergent active material or its precursor, described powder contains seldom or does not contain the detergent active material, and this powder is by the granulometric composition with predetermined mean particle size and particle porosity.
The present invention defines
Therefore; first aspect of the present invention provides a kind of production tap density to be no more than 750g/l; for example be no more than 700 or the cleaning composition of 650g/l; this method comprises that a kind of feed particulate material is put into the mixing tank/tablets press with stirring and cutting function with a kind of liquid component that contains detergent active material or its precursor mixes; described feed particulate material contains the detergent active thing of not enough this raw material 10% of weight percent, the d of this raw material
50Median size is 100-1000 μ m, and the particle porosity is at least 0.4.
The invention still further relates to a kind of cleaning composition with the inventive method preparation.The detailed description of the invention
The present invention results from unexpected a discovery, and promptly the tap density of product depends on the speed of rotation when mixing.This also is the function of selected given mixer, and but, the speed of mixing tank is low more basically, and the tap density of product is also low more.
Described novel method have two outstanding and be advantage independently.First advantage is by selecting to have had the powder raw material of needed mean particle size and porosity, can prepare medium or the low bulk density powder.
Second advantage is that the working condition that possesses spraying drying and mechanically mixing aggregation equipment at the same time obtains down.By give with the possibility of spraying drying goods as the raw material of mechanical aggregation process, the invention provides described combined method in the further handiness of producing aspect the washing powder goods.In this article, shortenings " NTR " is meant " non-tower approach ", promptly powder is by mix producing, rather than produces with spray-drying tower, even raw material itself is that what to produce by spraying drying also is like this.
Be advisable with 400-650g/l with its tap density of cleaning composition that the inventive method is produced, be preferably 450-650g/l, more preferably 500-600g/l.Further its particle porosity of the preferred cleaning composition of producing is at least 0.2, and more preferably at least 0.25.
Described feed particulate material shared weight percent in the composition of being produced by described mechanically mixing method is preferably 20-40% and is advisable with 10-75%.
Except with median size (for example d50) the expression size-grade distribution, if can being suitable for Rosin-Rammler, it distributes, can also represent size-grade distribution with the Rosin-Rammler number.This number calculates n power distribution of the following formula of described size-grade distribution substitution:
Wherein, R is the cumulative percentage that surpasses the powder of certain particle size D.D
rBe mean particle size, and n is a size-grade distribution tolerance.D
rWith n be the Rosin-Rammler number that is fit to the tolerance size-grade distribution.High n value means to have narrow size-grade distribution, and low n value means to have wide size-grade distribution.
Described method can be a continuation method, or carries out with the batch form.
One type the setting that is suitable for finishing described mechanically mixing comprises a super mixer/compactor, and described raw material and described liquid component are dropped in this device, forms the particulate state detergent.In a kind of preferred embodiment; this device also comprises a middling speed tablets press/compactor; particulate state detergent from described super mixer/compactor is devoted in this middling speed device; form thus or keep a kind of yielding state, subsequently resulting product is carried out drying and/or cooling.
An example of described super mixer/compactor is L ǒ dige (trade mark) CB30Recyzler.This device mainly is made up of a large-scale static hollow cylinder, and this is a horizontal positioned, and its diameter is about 30cm.Have a turning axle at this middle part, on this axle, paddle is installed.This device can rotate under the speed of 100-2500rpm according to needed densification degree and granularity.The paddle that is installed on the described axle can be to producing sufficient mixing effect at this stage blended solid and liquid.Its average residence time depends on speed of rotation, the position of paddle and the cofferdam of outlet opening of axle to a certain extent.
