Softening data
Prepare preparation in the table 2 according to above-mentioned preparation method.Described preparation is used for laundering of textile fabrics, carries out flexibility then, the flexibility level of the fabric of assessment washing.The flexibility test is carried out in true washing machine test, and it carries out in the European open front automatic washing machine of typical case.Washing is carried out about 2 hour time and is comprised 2 rinsings.Tested isopyknic product (35 milliliters).
Washing load is made of " ballasting " part, and this ballasting part is washed sheet material by cotton and cotton and constituted, to realize 2.5 kilograms standard wash weighing load.In fact be used to check that the cloth of flexibility is the cloth sheet of HEAVY FLANNELETTE toweling (terry-towelling), it has carried out pre-roughening in advance, and it is measured as about 20x20 centimetre.Dry cloth subsequently.Carry out 4 repetitive scrubbings and formed, assess the flexibility of toweling controller afterwards to allow the flexibility influence.Flexibility is undertaken by volunteer's panel of experts.They are required towel is classified to the most coarse order according to the most soft, use 7 grades of scorings (1=is the most soft, and 7=is the most coarse).The score of given product is added up and calculating mean value.
Used anion surfactant is LAS acid.It is neutralized in preparation and forms linear alkylbenzene sulphonic acid (NaLAS).The actual weight of employed anion surfactant is based in this and form, and the therefore preparation weight of a little higher than LAS acid.The molecular-weight average of LAS acid is 326.5, based on structural formula (CH

3Na).It is 10.7 grams (x348.5 calculates according to (10 gram/326.5)) that the LAS acid of 10 grams will make the gross weight of anion surfactant.
Embodiment 1-3 according to WO2008/022838 has prepared a comparative example (contrast A).According to definition herein, these embodiment comprise the nonionogenic tenside of 12 weight %, 10.5 the anion surfactant of weight % (is made (round up from 10.47 grams and obtain) by 7.5 gram NaLAS, the promptly and acid of form+3 restrain sodium xylene sulfonates, it is classified as tensio-active agent and hydrotropic agent simultaneously), 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.The contrast category-B is similar to contrast A, but nonionogenic tenside and anion surfactant ratio increase to and account for overall about 30%.Comparative example C and D are additional embodiments.Described preparation is compared with the control formulation that does not contain any cationic polymers (contrast).
Table 2
| The preparation numbering | The ratio of NI:An | The wt% nonionic | Wt% lipid acid | wt%An | The wt% cationic polymers | The wt% of total surfactant | Average flexibility score value |
| Contrast | 0.96:1 | 20.1 | 4.8 | 21 | 0 | 41.1 | 6.7 |
| Contrast A | 1.15:1 | 12 | 10 | 10.5 | 0.45 | 22.5 | 5.1 |
| Contrast B | 1.2:1 | 16 | 10 | 13.4 | 0.45 | 29.4 | 6.2 |
| Contrast C | 0.94:1 | 15 | 10 | 16 | 0.45 | 31 | 3.7 |
| Contrast D | 0.47:1 | 10 | 10 | 21.3 | 0.45 | 31.3 | 3.3 |
| The present invention 1 | 1.41:1 | 18 | 10 | 12.8 | 0.45 | 30.8 | 1.7 |
| The present invention 2 | 1.87:1 | 20 | 10 | 10.7 | 0.45 | 30.7 | 1.3 |
Described softening minute value representation be that low more score equals good more flexibility level.As above table is clear shows that the weight ratio of nonionogenic tenside and anion surfactant (NI:An) has remarkably influenced for the preparation of 1.25:1-2.25:1 demonstrates to fabric softness when being used for wash conditions.
