Abstract

The present invention provides a process for making a shaped marbled detergent bar including the step of feeding an extrudable non-soap detergent composition into an extruder comprising at least one screw rotatably mounted within a barrel having inlet and outlet, where rotation of said screw conveys said composition from the outlet into a frusto-conically converging pressure zone, which converges into at least one nozzle from which a billet of extruded detergent emerges; and an apertured plate interspersed between said outlet ad said pressure zone. Said process additionally includes the step of injecting a coloured liquid into said composition through an injection means, located upstream of said apertured plate, the pressure of injection being higher than that generated within the extruder. Furthermore, the billet produced in said process is split once parallel to the axis of said screw, by splitting means, as it is extruded from said nozzle, so as to provide suitable marbling on the billet.

Description

Be used to prepare method and apparatus with marblized detergent bars

Invention field

The present invention relates to be used for the method and apparatus that preparation has marblized detergent bars (using detergent bars for laundry especially, more particularly is non-soap detergent bars).Developed the present invention, be mainly used in the preparation laundry and use detergent bars, hereinafter it has been described with reference to the application.Yet, will recognize that the present invention is not restricted to this specific Application Areas.

Background and related art

The cleaning compositions of solid form and liquid phase are than being cheap, because its lower packing cost is to popularize very much in this form of developing country especially.In multiple solid form, strip (bar) is popularized, and positive fast-developing in developing country market, because it is worth payment (value delivery) preferably.

Raggle-taggle (variegated), streaky (striped), marblized (marbled) or spotted (mottled) bar (being also referred to as heterogeneous in the prior art) a lot of years of cicada is arranged.It can form visually attractive mosaic pattern on this.This attractive pattern is that the human consumer enjoys a lot.

Heterogeneous is mainly used in skin clean purpose, i.e. personal cleansing.

Therefore, have marblized pattern on the soap and give its abundant outward appearance, striped or other similarly structure make soap unusual.

Heterogeneous normally by one of following method preparation:

(i) use blend color soap slice (noodle)

(ii) use the slice that scribbles dyestuff

(iii) dyestuff injection

(iv) coextrusion and

(v) non-extruding

In these methods, the dyestuff injecting method is by wide coverage.

US 3890419 (ARMOUR-DIAL INC) has described the method that is used to prepare heterogeneous soap (personal cleansing) bar, wherein by a plurality of dyestuff injection ports that are present in the perforate pressure plate dyestuff is expelled in the soap-cake, this perforate pressure plate is separated cylinder and taper pressure zone (cone) of forcing machine.Dyestuff is introduced in the soap-cake by forcing machine and when entering this cone at it, orifice plate is separated cylinder and cone.This method is used to prepare streaky, with to have marblized different.

On the other hand, GB 1316477 (UNILEVER PLC) has described the method that is used to prepare heterogeneous soap (personal cleansing) bar, wherein dyestuff is expelled in the soap-cake in the cylinder of forcing machine.Different with the US 3890419 that wherein dyestuff is injected by the port that is positioned at the perforate pressure plate, the feature of a plurality of dyestuff injection ports (collection pin) is in cylindrical body.In GB ' 477, dyestuff is incorporated in the soap-cake, it enters cone by orifice plate.This specification sheets is also advised as the alternative of using the collection pin, dyestuff can be extruded the aperture injection of screw flight or axle by being arranged in hollow.

US3663671 (LEVER BROTHERS, 1980) has described and has been used to prepare the method with marblized soap bar, and it can make single screw extrusion machine extrude two streaky detergent material streams, is used for being processed into subsequently the sanitising agent small pieces.Final extrusion board has two perforates.When it enters the coextrusion cone that is right after in the orifice plate downstream by single screw extrusion machine and perforate pressure plate, liquid dye are expelled in the detergent block (detergent mass).The partition member that provides also has been provided has been extended to the downstream from pressure plate, detergent block being separated into two streams, with liquid infusion in each stream.Screw thread terminal in the common screw extrusion press and upstream plate face next-door neighbour is also disclosed, but can be with its improvement so that the enough apart spacing of screw rod and plate so that more isobaric distribution to be provided on board plane.

Aforesaid method can be used for preparing heterogeneous soap (personal cleansing) bar.

Although from these patents available draw well the soap bar of being mentioned to be construed to comprise detergent bars and non-soap detergent bars, and in the type of sanitising agent, there is not a key point, as long as it can be extruded with non-essential composition, the inventor observes owing to following reason, and situation is really not so.

Heterogeneous detergent bars (the marblized non-soap detergent bars that particularly has acceptable degree) can not prepare by being used to prepare the method with marblized soap bar.This is because it is more soluble being used as the synthetic surfactant (for example linear alkylbenzene sulphonic acid) of active ingredient in detergent bars, so dyestuff diffuses out in the main body of detergent bars easily very apace.Existence at this middle high-content mineral material (filler) makes the viscosity that can extrude piece (extrudable mass) be significantly higher than soap bar.Therefore, liquid dye can not be expelled to extrude in the piece, because owing to the mobile counterpressure that produces that can extrude detergent block is enough high to occupy the hole (perforate) of (billet) this dyestuff injection device (promptly gathering pin).In addition, owing to can extrude the high viscosity of piece, there is higher resistance in dye diffusion in this piece.In addition, only a part of liquid can be remained in this piece,, and extrude the basic successive layer of formation on the surface of bar because remaining liquid moves to the surface of this piece when it is compressed.

Obviously the successive layers that exists on the finished product will can not provide required marblized outward appearance that has.

The inventor has also observed when being positioned at orifice plate described in dyestuff injection device such as the US 3890419, resulting detergent bars (being non-soap detergent bars especially) does not show to have the marbling outward appearance, because dyestuff and detergent block are not mixed into suitable degree.Similarly, when being positioned at cylindrical body described in dyestuff injection device such as the GB 1316477, resulting demonstrates basic successive layer in its surface.

Carried out the trial of preparation heterogeneous (scored) non-soap detergent bars in the past.WO2003/083034 (Unilever) has described a kind of method, and the wherein scored detergent bars composition that is mainly non-soap comprises that having of 5～50wt% is the bar that comprises the striped prescription of soap, non-soap or mixture less than the stain remover active substance of 25% soap content and 0.1～10wt%.This striped prescription comprises the soap that is up to 80wt% or is up to synthetic non-soap sanitising agent or its combination of 50wt%, has the water and the mineral filler that is up to 70wt% of 5～30wt%.This scored sanitising agent is by the coextrusion of two kinds of extrudable cleanser compositions preparation.

The inventor has been found that now and uses the dyestuff injecting method to prepare the method for heterogeneous detergent bars (more particularly being heterogeneous non-soap detergent bars).This method together the advantage compared of extrusion method be that it is comparatively simple and manufacturing is different with scored heterogeneously have marblized.

In addition, also provide and injected several different colours simultaneously to obtain the possibility of complicated patterns and design.

Use method described in the prior art can not make heterogeneous marblized detergent bars that has, especially for the non-soap detergent bars of fabric washing or hard-surface cleaning.

Therefore, for using the dyestuff injecting method to prepare heterogeneous marblized detergent bars that has, be that the method for non-soap detergent bars also exists the demand that is not met especially.

Goal of the invention

The purpose of this invention is to provide and use the dyestuff injecting method to prepare heterogeneous marblized detergent bars that has, is the method for non-soap detergent bars especially.

The inventor has been found that if make extrudable detergent block by perforate pressure plate (being also referred to as fillet device plate (noodler plate) in the prior art) after the injection dyestuff, it can mix dyestuff with piece by forming fillet before entering the pressure zone of truncated cone mutually, using the dyestuff injecting method can prepare heterogeneous detergent bars, is non-soap detergent bars especially.

In addition, it has been found that at the exit end of the cylinder of the forcing machine of perforate pressure plate before directly and the qualification of the distance (spacing) between the perforate pressure plate to have obtained better control in the method, because can carry out better mixing to colored liquid and detergent block.

In addition, the inventor observes under the situation of shaping solid cleaning agent, and the screw shaft that the billet of sanitising agent need be parallel to forcing machine is rived in fact once, has marblized outward appearance to provide on the whole surface of the bad section of extruding.

The inventor also observes and must more particularly under the pressure of the pressure that produces, inject colored liquid in being higher than the detergent block extrusion under fully high pressure.It is higher to remove non-pressure, and detergent block can have been stopped up in the tip of injection device.

Detailed Description Of The Invention

According on the one hand, the present invention relates to be used to prepare the method for the marblized non-soap detergent bars of having of shaping.This cross section can be rectangle, square or circular.Preferred this cross section is a rectangle.

Term used herein " non-soap sanitising agent " comprises the composition of the synthectic detergents that comprises positively charged ion, nonionic and anionic cleaning agents kind, for example alkyl-sulphate, alkylaryl sulfonate, sulfonated alkane and sulfonated longer chain fatty acid, pure sulfuric ester and B oxidation fat alcohol.More particularly, the non-soap sanitising agent of term used herein comprises and mainly comprises this synthectic detergents (promptly greater than 10% synthectic detergents) and less than the composition of 20% soap (being an alkali metal salt of lipid acid).

An alkali metal salt of term " soap " expression lipid acid.

According to its composition, this detergent bars can be used in fabric washing or dishwashing detergent.

This non-soap cleanser compositions also can be the fabric washing bar of zero mineral type (Nil-mineral type) (promptly have and be less than the 10wt% mineral content).

Term " has marblized " to comprise equivalent terms, for example raggle-taggle or spot look, and the outward appearance of expression shaping solid cleaning agent, wherein one or more colored liquids are mixed in together with complete irregular mode and detergent block, and the random whirlpool outward appearance with marblized shaping solid cleaning agent is provided thus.Therefore, having marblized outward appearance is wherein to present with irregular array a plurality ofly discrete to have different in width separately and along the contrasting colour striped of the degree of depth of its length or the outward appearance of streak.This outward appearance with only on the irregularity of streak shape appearance tool to have striped be different, particularly by this color fringe wherein its boundary weaken be used for different with the mode of extruding the piece fuzzy Fusion.Be to be understood that this effect is not reproducible fully between different bars, so when each billet is cut into inch strips, the bar that generation is had different marbling outward appearances.Because these surface abrasion in use, as seen the marbling outward appearance of this inside will become.Can will have the marbling effect that spreads all over this continuously by the typical the finished product that present method obtains, so that in case by using wearing and tearing, along with painted texture exposed day by day gradually, this marbling pattern still continues, its geometrical shape has slight change, and the color change on this different level has the nuance that almost can't discover.

In the extrusion of detergent block, although the detergent block extruded in the systolic pressure district of truncated cone is passed through the translatory movement of extruding but still passed through violent stirring.Its reason is the high counterpressure that the viscosity owing to this piece produces.Since this, towards pressure span internal surface cumulative piece because the almost injected colored liquid of " piece stirring " phenomenon make dirty (smudged).The piece of making dirty on the side, pressure span in the heart piece in cone is extruded, and therefore applies the surface of extruding blank.Therefore the result is when this blank is cut into wall scroll, can not see this marbling effect on the surface of this blank.The inventor finds and can see this marbling effect on the whole surface of the bar of this blank and cutting-out, rives once by the axle that this blank is parallel to this screw rod, is more preferably extruding on the plane, to provide marbling on this blank surface.This screw rod can have a plurality of axles.Can be by suitable location this device of riving rive extruding outside the plane.This realizes that by means of riving device this device of riving is a template, has a pair of punch die, and the blade with blade is set between described punch die, and described blade is positioned to parallel with the axle of screw rod, and preferably in extruding the plane.Although it is parallel with the axle of screw rod that the blade orientation of preferred template becomes, blade also can be positioned at any other direction with respect to screw shaft, and for example blade can be positioned to vertical with this screw rod.Necessary part is that the piece of extruding is rived once, and this riving can be positioned at any direction by the device of will riving and realize.Preferably blank one being split is two, is preferably two equal half, because its center from this piece represents the marbling effect.Two blanks that the core of the blank of not riving then forms after being formed on and riving separately have marblized surface.

In addition, preferably this template has a pair of slit, and is adjacent with each punch die, and it can be at its when nozzle occurs (when it the is extruded) outside 1～5mm on this billet surface that prunes.This makes this marbling outward appearance manifest from upper surface easily.

According to method using appts of the present invention, promptly be included in and take place herein that detergent block is extruded so that this piece presents the forcing machine of the cylinder of billet form.This cylinder has entrance and exit, and preferably the spacing of the outlet of this cylinder and orifice plate is 5～500mm, more preferably 250～350mm.

Extrusion pressure in the cylinder is 10～1000psi, more particularly is 20～300psi.Increase gradually to top hole pressure from the inlet of this cylinder, very high in the pressure zone of truncated cone.Because towards this very high pressure of this cylinder outlet, therefore when when injecting near exit or its, must the injection pressure maintenance of colored liquid is higher than this pressure.

Cylinder will comprise a rotatable screw rod of installing usually, but preferably this cylinder is divided into a pair of compartment in the longitudinal direction, and wherein each compartment comprises a screw rod.In this structure, screw rod rotates with reflux type, thus extrudable block transfer is arrived in the pressure zone of truncated cone.

Temperature in vogue in cylinder preferably should be maintained at below 70 ℃, more preferably below 60 ℃.

In some cases, it is necessary that cylinder is cooled off, and for this purpose, cylinder has cooling jacket.Preferably, mold pressing is to carry out under 60 ℃～80 ℃ blank temperature.

Preferably, screw rod has 3～15 screw threads, more preferably 4～12 screw threads, most preferably 4 screw threads.Can regulate the quantity of screw thread and the size of screw rod (size) to adapt to preparative-scale.

Preferably, injection device at screw rod between the exit end the 2nd of cylinder and the 4th screw thread.Preferably, use at least one pair of injection device, especially be divided into when all having screw rod in two compartments and each compartment at cylinder.In this case, adjacent with each screw flight a device is set.In the present invention, colored liquid is expelled in the piece of compacting in by the cylinder process at it.Preferred one or more injection the in the nozzle that extends by a series of walls by the forcing machine cylinder, each nozzle have by the liquid flow of pipeline and volumetric pump separately.The position of each nozzle can change between the inlet end of this cylinder and exit end.Preferably with the solid color liquid working time, use a series of four nozzles, so that additive is only injected at single point.Can use similar injection, especially when needs are injected multiple colored liquid (for example injecting different dyes stream) by a plurality of nozzles.

Nozzle is projected in the space between cylinder and the screw rod.Reason for this reason provides the spacing of 2～5mm between the inwall of screw flight and cylinder, make screw thread can not contact the inwall of cylinder.Screw rod preferably all has corresponding registration breach (registering notch) to each nozzle.In this case, dyestuff is expelled near the position of the root diameter that is about as much as screw thread the screw front end, and in the face of the front end of forcing machine the time, had been 4 o'clock for left screw rod and is being the angle position at 10 o'clock for right screw rod.Necessary is, the injection of colored liquid occurs under the sufficiently high pressure pressure with the detergent block extruded that surpasses the forcing machine cylinder interior, so that can on the collection pin, not show any counterpressure and stop up thus under the situation of pin, the injection colored liquid.The injection pressure of preferred colored liquid is 400～1200psi.More preferably pressure is 500～1000psi.The size of gathering the pin opening can change according to the demand of colour injection, but is preferably 0.2～20mm, and more preferably 0.3～10mm most preferably is 0.3mm.

The type of colored liquid to be injected is not crucial, is nonbleeding dyestuff or pigment, for example D﹠amp although preferably have color substance; No. 5 dyestuff of C Green.It is crucial that colored liquid is expelled to pressure required in the flow of detergent block, and it should be greater than the pressure that produces in the extrusion in cylinder.

Mobile or fluid materials represented herein in term " colored liquid ", has the soap-cake that is injected into it and form correlated color.Colored liquid is fat soap matter solution preferably, for example dyestuff or pigment, but also can be pigment or dyestuff water, alcohol, glycerine or other can be compatible with detergent block liquid in suspension or emulsion.Preferred colored liquid is to comprise that 0.1～10wt% dyestuff and residue are the composition of polyvalent alcohol (for example glycerine).Preferred colored liquid has following composition by weight percentage: water 9.5%, glycerine 83%, Xylo-Mucine 1.5%, Blue BVS Paste 2%,

Green 111254%.

Under the situation that has a plurality of colored liquid injection points, supply to the internal portion that the interior dye solution of cylinder region intermediate is mainly used in painted sanitising agent.The amount of dye of introducing at this point should be 30%～80% of used dyestuff total amount.Remaining dye solution introducing is arranged in from the 1st sanitising agent to so-called " end regions " of the 3rd screw flight of cylinder exit end.With at least one, preferred 2～4 screw flights separate end regions and region intermediate.The dye solution that is incorporated in the end regions is mainly used in the edge section of sanitising agent billet painted.The injection device number that is positioned at this zone is preferably 2～6, although can use this injection device that is fit to number arbitrarily.The injection device branch can be arranged and be distributed on the circumference of cylinder if desired.

Preferably on the direction of motion that can extrude cleanser compositions, inject colored liquid, because the obstruction at the injection device tip that its reduction or prevented directly contacts with detergent block.

Can use the next painted detergent block of normally used dyestuff in soap industry.Need in dye solution, add thickening material, to improve its viscosity.The thickening material that is fit to is for example derivatived cellulose, for example carboxymethyl cellulose or methylcellulose gum; Alginates, starch, protein hydrolysate, polyvinyl alcohol, polyvinylpyrrolidone, polyacrylic ester, polyoxyethylene glycol and can be dissolved in maybe can prepare in the water and make its swelling other polymkeric substance natural or synthetic source in water.For the marbling of pastel tone, every 100kg detergent block needs 10～40g dyestuff usually.The bright pattern sanitising agent of preparation needs several times of this amount, promptly 2～5 times.Different coloring solutions can be supplied in different zones and the feedway to realize that multiple attractive color combination and marbling pattern also are fine.Preferably, in order to reach required contrast gradient, with the liquid of the relatively large volume of injection.

The inventor observes not to be had under the situation of orifice plate, has only kept a part of liquid in piece, and remaining along with its compression all being moved to the surface of this piece and form basic successive layer on this surface.

By using orifice plate to relax this moving, it can carry out the mixing of some required degree to this colored liquid and detergent block.

Except that using orifice plate, preferably this template has a pair of slit, and described slit is adjacent with each punch die, with the outside 1～5mm on the billet surface of pruning when it occurs from nozzle, to show the marbling outward appearance under the billet surface.
