The mildness test
Come the mildness of evaluation group compound with method (hand dip test) in vitro method (zein solubilising) and the body.
The zein value
The zein lyotropy is to be used for assessing the ex vivo technique of shampoo and other individual product's tensio-active agent to the mildness of skin.
E Gotte is at Proc Int Congr Surface Active Subs, 4th, and Brussels,
3,83-90, this technology of introducing in (1964), with the lyotropy of corn grain master albumen-zein as the tensio-active agent or the observed value of the roughness of the detergent composition of prescription fully.This is well to test with body build-in test dependency, and does to such an extent that comparatively fast be easier to.
Method therefor and Gotte are described basic identical, and difference is to adopt the higher concentration of 5 grams rather than 2 gram samples.
Since the lyotropy of zein is the observed value of roughness, then use the observed value of reciprocal value, and the value of being somebody's turn to do is high more as mildness, it is gentle more to fill a prescription.The zein value reciprocal of composition of the present invention is as follows:

Scourability
With the washing of Terg-O-Tometer method comparing embodiment 1,2,7 and Comparative Example A An and deposition properties again.
Wash in Terg-O-Tometer with test cloth (evenly dirty pieces of fabric).
In same Terg-O-Tometer, with four samples of four stain tests.Under specified requirements, each sample is repeated four experiments.Carry out this test at random to make the minimum that influences between the two Terg-O-Tometer stains.Test cloth and press dried with steam with the hard water rinsing.Goods with two kinds of dosage levels (1 and 3g/l) wash.Wash conditions is as follows:
Terg-O-Tometer condition: 100rpm washed 20 minutes
The ratio of liquid and cloth: 33: 1
Temperature: room temperature (about 25 ℃)
Volume of water: 1 liter
The water hardness: 20 H
Ballast weight: destarch cotton
The water hardness is enhanced 20 H, with the low production dosage of 1g/l guaranteeing and may assess scourability under the poorest wash conditions, and the higher product dosage of 3g/l real dosage level when representing to hand-wash.
Used test cloth is as follows:
Test cloth 1 (cotton of band fat and particulate soil)
Test cloth 2 (cotton of band fat and particulate soil)
Test cloth 3 (WFK 20D) (the polyester/cotton fabric of belt leather fat)
Test cloth 4 (WFK 30D) (polyester textile of belt leather fat)
Each washing is respectively monitored with the test cloth of three 7cm * 7cm for every kind.
After the washing, each load with 2 liters with twice of identical water rinse of the used water hardness of washing (20 H).Remove test monitoring cloth then, dry 1 minute and press dried then.
Assess scourability by measuring all monitoring cloth at the reflectance increase Δ R460* of 460nm (not comprising ultraviolet ray).The results are shown in following table 1 and table 2.
Between four embodiment, there is not obviously difference.

Deposit again
When the dirt deposition of removing in the washing process was got back on the fabric, deposition had again taken place.
Make monitoring cloth with two different clean fabrics, adopt Terg-O-Tometer test method(s) same as described above to measure deposition again.Use reflectance changes delta R460* (be negative value under this situation, promptly increase reflection) to measure the deposition again of dirt again.
Because deposition is a kind of storage effect again, so this method is made up of 8 accumulation washings (depositing in the washings continuous washing deposition monitoring cloth 8 times more again).Carry out this test at random the influence between the stain between two Terg-O-Tometers is reduced to minimum.
Used fabric is as follows:
White 100% spun cotton
The white balling-up is cotton to be linked
During each the washing, every type of each monitoring cloth with three 7cm * 7cm.
Used dirt is a large amount of (0.1g/l) carbon blacks (aquadag), to strengthen test condition.
Wash conditions is as follows:
Product consumption: every liter 3 gram
Terg-O-Tometer speed: 100rpm
Dirt sources: 0.1g/l carbon black
Temperature: room temperature (about 25 ℃)
The ratio of liquid and cloth: 40: 1
Volume of water: 1 liter
The water hardness: 20 H
Soak time: 30 minutes
Washing time: 15 minutes
Ballast weight: destarch cotton
After the washing, filter monitoring cloth, use the water rinse twice 2 minutes of 1 liter of 10 H again to remove washing lotion.Then, dry 2 minutes and 40 ℃ of following tumble dries 10 minutes.
Respectively measure reflectance after 4 washings and 8 washings.The results are shown in table 3 and table 4.
