Embodiment
The perfume compound deposition that embodiment 1 improves
Show the deposition of using microfibrous cellulose to improve fragrance particle in this embodiment.The fragrance particle (perfume compound encapsulate (perfume encaps)) of test packing is from there being and not having the deposition the laundry formulations of microfibrous cellulose.Also test adds the perfume compound encapsulate of Viscogum BE deposition aid modification.The microfibrous cellulose that uses is for buying from CP Kelco.
Embodiment 1a comprises the synthetic of beneficial agent particulate perfume compound
Through with high speed homogenizer (Silverson) with 10,000rpm mixed 10 minutes, Viscogum BE (11.2g) was dissolved in the deionized water (739.14g) of heat (70-80 ℃), up to dissolving fully.Then, under the condition of leaving standstill, this solution is cooled to room temperature.Then, it is transferred in the reaction vessel that overhead type whisking appliance, condensing surface, thermopair (being connected to heating jacket) and nitrogen inlet are housed.
Add perfume compound capsule (1894.7g, 53.2% solid, 30 μ m particle diameters) and vinyl-acetic ester (112g), with nitrogen purging inclusion 10 minutes, afterwards during entire reaction, with nitrogen blanket covering container and inclusion.Then, temperature is elevated to 70 ℃, and adds aqueous ascorbic acid (2.8g in the 25g deionized water) and aqueous hydrogen peroxide solution (8g, 35% activity (active)), with initiated polymerization.
After 90 minutes, further add a certain amount of aqueous ascorbic acid (0.56g in the 5g deionized water) and aqueous hydrogen peroxide solution (1.6g, 35% activity) to improve kinetics, make polymerization continue 30 minutes again.Then, under agitation, sample is cooled to room temperature.The white latex that obtains is made up of～40% solid.Remaining vinyl-acetic ester is about 1000p.p.m., it is equal to＞and 99.5% conversion of monomer.
Embodiment 1b in the presence of microfibrous cellulose, the capsular deposition of LBG-PVAc modification
Measure the perfume compound capsule deposition of self simulation washing test in the presence of microfibrous cellulose as follows through turbidity:
Use laundry liquid concentrator washing composition (Persil (trade mark) " Small and Mighty "), carry out two groups of washings with the perfume compound capsule LBG-PVAc modification with unmodified.In the presence of microfibrous cellulose, test for one group, test not existing under the microfibrous cellulose for one group.
1) preparation of washing lotion
The perfume compound capsule particle of the unmodified or LBG-PVAc modification of 0.05g (500ppm in washing lotion) is mixed with laundry liquid concentrator washing composition (0.23ml); A kind of microfibrous cellulose that do not contain; A kind of microfibrous cellulose (with respect to washing composition (on detergent) 0.125%w/w) that contains obtains homogeneous dispersion.Add the Wirral water of 100ml, and stir this mixture, every kind of washing lotion is joined Linitest to disperse equably
TM(to each sample, carry out washed twice, get MV as a result) in the cylinder.From each, get the 5ml aliquots containig, use 5cm cuvette (cuvette) to be recorded in the absorbancy of 400nm.This absorbance representative 100% particle in the washing lotion before the simulation washing process.
2) simulation washing-device and step:
The not fluorescent cotton fragment that is measured as 20cmX 20cm is put into each washing lotion, sealing Linitest cylinder.
Linitest is Laboratary type washing machine (Ex.Heraeus).This device designs and is assembled into the requirement that meets the international standard testing regulation.It is used on a small scale washing and detergency test, particularly when needs hang down liquid/clothes ratio.
The commercially available obtainable Linitest that various modes is arranged.The pattern of using in this example has single rotating speed 40rpm.Carriage (carrier) be for can holding the steel container of 12 500ml, and can operate reaching under 100 ℃ the temperature.
Linitest comprises 20 liters of grooves, system and drive units.In the tubular heating element heating washing lotion of the lasting thermostatically controlled (permanent thermostatically controlled) of trench bottom to temperature required.Stainless steel structure has been guaranteed the net heat transmission to sampling receptacle fully, and this sampling receptacle is installed on the rotation horizontal tray of geared motor driving.The mode with continuous action of rotatablely moving of carriage with liquid from container one end " throwing " to the other end.This motion simulation machine washing process, and through using steel ball bearing or dish (steel ball bearings or discs) to obtain additional mechanical effect.
The Linitest cylinder is connected to the Linitester carriage, and rotated 45 minutes down, to simulate main washing at 40 ℃.
Then, take out clothes, use the hand wringing, gather the residue washing lotion of 5ml aliquots containig, and use the 5cm cuvette to measure absorbancy as previously mentioned at 400nm.
By preliminarty calibration curve interpolation (interpolation), can measure washing and remain on the granule density in the liquid afterwards, thus, the sedimentary level (washing deposition) on the clothes is measured in difference.
Then, rinsing Linitest cylinder is put back to the clothes of " wringing " in the cylinder up hill and dale, and adds the Wirral water of 100ml.Discharge the Linitester bath water, and said cylinder is connected to carriage, rotate 10 minutes down with the simulation rinse cycle in envrionment temperature (～20 ℃).Then, take out clothes, use the hand wringing.Gather the washing lotion of 5ml aliquots containig, and measure absorbancy at 400nm.As preceding, the preliminarty calibration curve interpolation allow to be measured the granule density of removing from clothes during the rinsing, and with rinsing before sedimentary initial level relatively, measure the percent loss from the clothes.Repeat this process, with the loss of simulation and mensuration rinsing for the second time.
Following table has been listed the result.
The deposition of table 1 perfume compound
Therefore, can find out that for unmodified perfume compound capsule, also in particular for the perfume compound capsule of using deposition aid modification shell, microfibrous cellulose has all improved the perfume compound deposition from table 1.
