Soap bar
In the embodiment of the present invention of preparation laundry bars, this method comprises mixes the amine oxide component with a kind of acid, make premixture; This premixture, anion surfactant and alkali-metal salt are mixed; With the composition that obtains is made bar.
The inventive method can be used the device that has some or all following key equipments of conventional soap of preparation or detergent bar: mix device/mixing tank (for example spiral ribbon-type blender), shredder, homocline plodder (for example duplex plodder), two-part vacuum plodder, sign printing/cutting machine, cooling tunnel and wrapping machine.
In general method, the amine oxide component is mixed in mixing device, planetary-type mixer, kneader and/or extrusion machine with acid, make premixture.This premixture is mechanically operated to realize homogenizing and the neutralization of finishing this premixture.
Then, premixture is mixed in mixing device with other starting material (comprising anion surfactant and alkali-metal salt).The mixture of this premixture and other raw material is called as base-material.Add the optional tensio-active agent of other soap and other then, then add washing assistant and other auxiliary component arbitrarily.If need, can use the basic salt of poly-phosphate as neutralizing effect.Can carry out 1 minute to 1 hour high shear mixing, common mixing time is about 2-20 minute.Preferably, temperature is about 74 ℃-80 ℃.The example that can be used for the equipment of high shear mixing comprises the Engineers by Fabdecon, the Sigma Mixer high-shear mixer that Bombay India produces; Or by Littleford Day, Inc.Kentucky, the plough chip mixing tank that U.S.A produces.
The mixture of mixing in the device is loaded in the surge tank.This product is delivered to shredder from surge tank.Along with mixing tank is ground, mixture is cooled to about 40 ℃-62 ℃.Preferably, flow through shredder by cold water and come cooling mixture, it makes the mixture cooling of grinding again.
After the grinding or behind the preliminary press strip after grinding, product is delivered under high vacuum operated then, for example depress in two vacuum plodders of operation, so that remove the air of holding back at 400-740mm mercury.Squeezing prod also cuts into the bar of desired length, the trade name of product in the printing.Can cool off the bar of this printing, for example in cooling tunnel, pack then, case and send into the warehouse.

Particle
This amine oxide component/sour premixture can be used for preparing low density (being lower than 550g/l) and high-density (550g/l at least) granular laundry detergent compositions.This high density detergent composition generally comprises about 30%-90% detersive surfactant.
The spray-drying process of available standards prepares low-density compositions.Can in all sorts of ways and equipment prepare high density granular detergent composition.Use spray-drying tower to prepare granular laundry detergent in the common industrial implementation in this area, usually its density is lower than about 500g/l.Therefore, if the spray-dried detergent particle that spraying drying as the part of overall process process, makes must use following method and apparatus further closely knit.In addition, the prescription teacher can save spraying drying by using commercially available mixing, closely knit and granulating equipment.It below is the non restrictive description that is applicable to this equipment of the present invention.
Can use super mixer/closely knit device in the methods of the invention, for example with the equipment of trade mark " LodigeCB30 Recycler " sale, it contains a static round shape mixing drum, has center rotating shaft in this cylinder, and mixing/cutting blade is housed on this axle.Other this kind equipment comprises the equipment of selling with trade mark " Shugi Granulator " and " Drais K-TTP80 ".Can be used for further closely knit operation such as the equipment of selling with trade mark " Lodige KM600 Mixer ", " Fukae High Speed Mixer " and " FoodProcessor ".
In a kind of operating method, said composition is produced with closely knit by two mixing tanks and the closely knit device of operation in order.Like this, required composition component can be with the mixing of Lodige mixing tank and by this mixing tank, and the residence time is about 0.1-1 minute, and by second Lodige mixing tank, the residence time is about 1-5 minute then.
In another way, the aqueous slurry that will contain required recipe ingredient sprays in the fluidized-bed of granule surface activity agent.The particle that obtains can be further closely knit by aforesaid Lodige equipment.
Prepared particulate final densities can be passed through various simple commercial measurements, and this technology generally comprises a certain amount of granulated detergent is assigned in the container of known volume, measures the weight of washing composition and with the grams per liter recording density.
Prepare this amine oxide component/sour premixture as stated above, add usually the preparation low density of injection tensio-active agent and the technology of high density granular composition then.In drying process with atomizing, preferably in the premixture forming process or afterwards, to wherein adding entry in addition.The slip that obtains can help the spraying drying of tensio-active agent.In not comprising spray-dired technology, the premixture of preferred lotion form.

Liquid oxidation amine generally is difficult to mix in the solid detergent composition by the preparation laundry bars and the particulate method of routine.The large quantity of moisture that this difficult major cause is this amine oxide is brought in the bar prescription.This moisture causes being difficult to processing and corresponding bar flexibility and/or particle problem of viscosity.Yet as the present invention, by with liquid oxidation amine and sour pre-mixing, the premixture that obtains can easily mix in solid detergent bar and/or the particulate composition, particularly in the detergent for washing clothes bar composition.Therefore, have many advantages, comprise the physical properties of improvement at relative detergent for washing clothes bar and/or the detergent for washing clothes particulate composition that comprises the amine oxide for preparing with other method of the each side of the present invention described in this document with embodiment.The physical properties of this improvement can comprise have been improved uniformity coefficient, reduced flexibility, easier processing, the easier packing of product that makes and transportation and better economy has in use been arranged.
Owing to many reasons, the soap bar softness is undesirable.For example, it can cause the difficulty in the following process bar step.In others, if bar is too soft, it can not discharging from plodder normally.In addition, soft soap bar can distortion in packing and/or transportation.Although the soft soap bar is through may hardening after about 2 weeks, the soap bar of the snap cure of coming out from plodder can transport and pack immediately.
Even people adopt economic method packing/transportation soft soap bar, avoid its distortion, but the human consumer uses the soft soap bar also to have several undesirable character.For example, relatively washing composition is to the using of fabric, and the human consumer has relatively poor controlled to it.Harder soap bar has lower toughness, moreover the feed of relative washing composition, makes the easier control of human consumer.
Use the inventive method to have and the similar bar hardness/soundness of laundry bars for preparing with solid amine oxide through routine processing with the laundry bars of liquid oxidation amine preparation.
The laundry bars of being produced by the inventive method has many other advantages, comprises the whipability of improvement, to the mildness of user's hand and the cleaning force of improvement, and does not have serious working ability problem.
Do not plan to be limited by theory, believe when the amine oxide contact acid, between acid and amine oxide, formed ion pair.Believe that this ion pair is to cause in the protonated interatomic electrostatic attraction that has lost its H30 hydroxonium ion period of the day from 11 p.m. to 1 a.m and amine oxide because of acid molecule.For example, about the premixture of HLAS and amine oxide, believe that ion pair is to cause because of the electrostatic attraction between the protonated Sauerstoffatom of electronegative HLAS sulfonate radical and amine oxide.This protonation comes from the oxonium ion of HLAS.More specifically:
R wherein
1, R
2And R
3As above definition, R
