Prepare as previously mentioned Comparative Examples A and B.The nonionogenic tenside of embodiment A and the weight ratio of soap (NI:soap) are 0.5:1, and the NI:soap of Embodiment B is than for 10:1, namely are in outside the bound of the scope that claim 1 provides.In the course of processing, it is unsettled that embodiment A is proved to be.
Embodiment 1-3 according to WO2008/022838 has prepared a comparative example (contrast C).According to wherein definition, these embodiment comprise the nonionogenic tenside of 12 % by weight, 10.5 the anion surfactant of % by weight (is made (round up from 10.47 grams and obtain) by 7.5 gram NaLAS, the namely and acid of form+3 restrain sodium xylene sulfonates, it is classified as tensio-active agent and hydrotropic agent), the cationic polymers of the lipid acid of 10 grams and 0.45 gram.The aggregate level of tensio-active agent is 22.5 grams, does not comprise lipid acid or its salt in the tensio-active agent level of this definition.Therefore, the weight ratio of the nonionogenic tenside of this embodiment and soap is ⒈ 2:1.Comparative example D is similar to C, but nonionogenic tenside and anion surfactant ratio increase to and account for overall about 30%.The cationic polymers (LR 400) that all embodiment 1-4 in the table 2 and Comparative Examples A-D comprise 0.45 % by weight.
Stability test
The 100ml sample is stored in the plastics pot of cleaning until 12 week.Store at room temperature that (22 ℃) carry out, and according to the physical instability of the assess sample that is separated, being separated to be defined as two or more layers have been formed in sample.Therefore can whether present unstable according to product, or whether it can be processed into finished product, thereby estimate described product.Following table shows the physical stability eigenwert of a series of preparations of making according to above-mentioned preparation method.
Table 2
| The preparation numbering | The ratio of NI:An | The wt% nonionic | Wt% lipid acid | wt%An | The wt% of total surfactant | Stability |
| Contrast A | 1:2 | 10 | 20 | 10.7 | 20.7 | Unstable (can not make) |
| Contrast B | 10:1 | 40 | 4 | 10.7 | 50.7 | Unstable (being separated) |
| Contrast C | 1.2:1 | 12 | 10 | 10.5 | 22.5 | Unstable (being separated) |
| Contrast D | 1.2:1 | 16 | 10 | 13.4 | 29.4 | Unstable (being separated) |
| The present invention 1 | 2.5:1 | 15 | 6 | 10.7 | 25.7 | Stable (surpassing for 12 weeks) |
| The present invention 2 | 3:1 | 18 | 6 | 10.7 | 28.8 | Stable (surpassing for 12 weeks) |
| The present invention 3 | 3.3:1 | 20 | 6 | 10.7 | 30.7 | Stable (surpassing for 12 weeks) |
| The present invention 4 | 4.5:1 | 27 | 6 | 10.7 | 37.7 | Stable (surpassing for 12 weeks) |
As above show and show that the weight ratio of nonionogenic tenside and lipid acid is that the preparation of 2.5:1-6:1 is more stable.
