Method of testing:
Yield stress and zero-shear viscosity method: yield stress and the zero-shear viscosity of measuring phase in the present composition before can be in being mixed into compositions, perhaps in being mixed into compositions after by suitable physical separation method as centrifugal, absorption, machine cuts, drip washing, filtration or other separation method with as described in be separated, measure the yield stress and the zero-shear viscosity of phase in the present composition.
Use the flow graph such as the TA Instruments AR2000 flow graph of scalable stress to measure yield stress and zero-shear viscosity.Measure in 25 ℃ of parallel-plate measuring system and 1mm gaps with the 4cm diameter.Described geometric system has 79580m
-3The shear stress factor, change stress into the torque axis that will be obtained.
At first, obtain the phase sample, and be held in place on the position of flow graph base plate, will measure solid (upper plate) and move on to apart from the position of base plate top 1mm.After fixing solid, remove the unnecessary phase of solid edge by scraping.If the described number average diameter that comprises mutually greater than about 150 microns passing through naked eyes or feel recognizable granule (for example globule), then is provided with less distance in 8 times that increase to 4mm or 95% volume particles diameter with the gap between base plate and the upper plate.If contain on virtually any size any granule mutually, then before measuring, remove this granule greater than 5mm.
By in 5 minutes interval from 0.1Pa to 1, the 000Pa program applies the continuous gradation of shear stress, uses logarithmic series, promptly measurement point is measured with the even interval of logarithmic scale.Ten times of stress of every increase are collected 30 (30) individual measurement points.Record stress, strain and viscosity.If measurement result is imperfect, if for example material flows out from the gap, then the result who is obtained is estimated, get rid of incomplete data point.Following mensuration yield stress.By they are taken the logarithm (is the end with 10), transformation stress (Pa) and strain (dimensionless) data.Only, log (strain) is mapped with Log (stress) for the gained data of about 30 points between 0.2Pa to the 2.0Pa stress.If the viscosity at 1Pa stress place is less than 500Pa-second, but,, to log (strain) mapping, carry out following Mathematical treatment then with Log (stress) then only for the data between 0.2Pa to the 1.0Pa stress greater than 75Pa-second.If the viscosity at 1Pa stress place is less than 75Pa-s, then zero-shear viscosity is the average of 4 ultimate viscosity numbers of gained (being independent point) in the test, and yield stress is zero, and does not use following Mathematical treatment.The following Mathematical treatment of carrying out.Use the data of specifying logarithmic transformation in the stress area, the result carried out the straight linear least square return, obtain formula with following form:
(1) Log (strain)=m*Log (stress)+b
To 0.1 to 1, the Coefficient m and the b that are obtained are used in the recurrence that each stress value of measuring between 000Pa (being independent point) utilization is obtained, and actual stress, utilize formula (1), can obtain log (strained predicted value.By the log that is predicted (strain),, can obtain the strain of the prediction at each stress place by getting antilogarithm (promptly each x being got 10x).Use formula (2), the strain and the actual strain of the prediction of each measurement point compared, obtain the variation % of each measurement point.
(2) strain of variation %=100* (strain of the strain-prediction that records)/record
Yield stress is first stress (Pa) that variation percentage ratio (%) surpasses 10% place, and because flow beginning or malformation begin, follow-up (higher) stress causes even the bigger variation than 10%.By for obtained between and comprise 0.1Pa to viscosity data between the yield stress, to be Pascal-second (Pa-s) that the first intermediate value viscosity is got by unit, can obtain zero-shear viscosity.After obtaining the first intermediate value viscosity, get rid of all viscosity numbers of 0.2 times little of 5 times big of ratio first intermediate values and ratio first intermediate value, to getting rid of the identical viscosities data at designation number strong point, get the second intermediate value viscosity number.So the second intermediate value viscosity that obtains is zero-shear viscosity.

The foam volume test: use graduated cylinder and slewing, measure the foam volume of cleansing phase, structured surfactant component or structured region in the structured multi-phased personal care composition.Use one 1, the 000mL graduated cylinder, it increases progressively with 10mL marks, and 1, the 000mL mark is 14.5 inches (for example, Pyrex 2982) apart from the height of its bottom inside.Distilled water (in 25 ℃ of 100 gram) is joined in this graduated cylinder.Graduated cylinder is clipped in the rotary apparatus, and this device is clipped in the position that the graduated cylinder center is crossed in its rotation axis crosscut with graduated cylinder.From syringe (weighing), 0.50 gram structured surfactant component or cleansing phase are expelled in the graduated cylinder along supernatant graduated cylinder sidewall, and graduated cylinder is sealed to guarantee correct dosing.When the evaluation and test sample, only use 0.25cc, other is constant.Speed with commentaries on classics in per 18 seconds 10 makes graduated cylinder rotate 20 complete cycles, is parked in vertical position then, to finish rotary course for the first time.Intervalometer is set, reserves the foam that 15 seconds time chien shih produces and discharge.After above-mentioned discharge process was carried out 15 seconds, the foam height (unit is mL) (comprising floatation of foam all water that are discharged to the bottom thereon) by record is upwards counted from the bottom recorded first foam volume, accurately to the 10mL labelling.
If foamy upper surface unevenness, then may observable graduated cylinder transverse section in the middle of the minimum altitude place as the foam volume first time (with the mL scale value).If foam is very thick, so that only there are one or a few to comprise foamy foam cell (" bubble ") across whole graduated cylinder, then will need height that at least 10 foam cell just can be full of place, this space as first foam volume, equally mL note upwards to count from the bottom.All greater than 1 inch unibody piece of foam, no matter where they come across, and all will be regarded as unfilled air, rather than foam on any yardstick.If the foam at top is in the pantostrat of himself, then will accumulate in the top of graduated cylinder and the foam of not discharging is also included within the measurement.Use ruler to measure the thickness of layer, with the foamy mL number that accumulates in there be added to measured from the foam mL number that the bottom is counted.The maximum foam height is 1, and 000mL is (even Zong foam height surpasses 1 of labelling on the graduated cylinder, 000mL).After rotation finished 30 seconds for the first time, beginning is rotary course for the second time.The speed of current rotary course and persistent period with the first time rotary course identical.Behind same 15 seconds efflux times, use with for the first time identical mode and write down second foam volume.Finish rotary course for the third time, and measure the 3rd foam volume in an identical manner, arranged the identical dead time in each discharge with between measuring.
Each postrotational foam result is added together, measure sum with these three times then and be defined as total foam volume, unit is a milliliter (" mL ".Instantaneous foam volume is the result behind the rotary course for the first time only, and unit is mL, i.e. first foam volume.In this test, the performance that compositions showed significantly is better than the analogous composition of conventional emulsions form as described in the present invention.
Shear index (n) and consistometric value (K): shear index (n) and consistometric value (K) and be the known and acceptable method that is used to report the viscosity characteristics of material, the use power law model, the viscosity that described material has changes with the shear rate that is applied.Term used herein " consistometric value " or " k " are measuring of viscosity, and unite the viscosity of use with the definition material with the shearing index, and the viscosity of this material is the function of shear rate.Carry out consistometric value and shear exponential measurement in 25 ℃.The unit of " consistometric value " or " K " is a pascal second.The unit of " shearing index " is nondimensional.
By applying shear stress, and use flow graph such as TA Instruments AR2000 (DE, USA 19720 for TAInstruments, New Castle) to measure shear rate, can measure phase viscosity.In following modes, measure viscosity with different shear rates.At first, obtain useful phase.Except to independent useful evaluate and test separately mutually, if there are more than one different (as immiscible) useful phases in the compositions, as for example siloxanes oil phase and hydrocarbon phase, then preferably they are separately prepared and/or be separated from each other, and be separated from each other and evaluate and test, though being the useful mixture that can be used as mutually of mixture such as emulsion, some evaluates and tests.
For mensuration, use the parallel plate geometry body of the diameter 40mm with 1mm gap, except that non-particulate, in this case, use the 2mm gap greater than 0.25mm.Flow graph uses standard parallel-plate practice, and the shear rate of edge is recorded as the test shear rate; And usage factor 2/ (π R
3), torque axis is turned to stress.In 25 ℃ of use scrapers, the sample that will comprise excessive slightly useful phase is loaded on the flow graph base plate, obtains the gap, and removes the unnecessary compositions that the solid outside is measured at the top.During removing unnecessary sample, fix top board.Make sample temperature and baseplate temp balance 2 minutes.Shear step in advance, described step is included in 50 hertz of (shear rate down cuts of 1/ second 15 seconds.Know as is known to the person skilled in the art, the shear rate of parallel plate geometry body is expressed as the shear rate of edge, and it also is a maximum shear speed simultaneously.Measuring after shearing step pre-, it is included in 25 ℃ made stress skyrocket to 1 from 10Pa at 2.0 minutes at interval, and 000Pa collects 60 viscosity number strong points with equidistant linear incremental model simultaneously.In this test, obtain the shear rate of at least 500 1/s, perhaps repeat this test with higher final stress value with new samples with same composition.Between test period, keep interior identical stress of unit interval to advance the speed, until the shear rate that obtains at least 500 1/s.Observe sample between test period, to determine that the top any marginal position of parallel-plate lower area does not all have sample to overflow between test period, perhaps replication remains unchanged at test period until sample.If after test several times, because sample overflows and can't obtain the result in edge, then replication stays excessive material in edge and gathers (not scraping off).If still can't avoid overflowing, then use the coaxial cylinders solid, in addition big excessive sample produces air pocket to avoid loading days.By only selecting the data point (Pa-s of viscosity unit between 25 to 500 1/s shear rates, the 1/s of shear rate unit), makes the result meet power law model, and use the viscosity logarithm that the logarithmic least square of shear rate is returned, according to power-law equation, obtain K value and n value:
μ＝K(γ’)
(n-1)
The value that is obtained by the log-log slope is (n-1), and wherein n shears index, and the K value that is obtained is consistometric value, is unit representation with Pa-s.
