The composition of the sodium fatty acid in table 2 is the same as that of example 1, and the soap chips of comparative example 1 are prepared in the same manner as example 1.
Comparative example 2
The mass percentage contents of the raw material components of one soap chip provided in comparative example 2 are shown in table 3.

In table 3, the sodium fatty acid is composed of saturated fatty acid salts and unsaturated fatty acid salts of C6-C20, the content of the unsaturated fatty acid sodium is 18%, and the rest is saturated fatty acid sodium, wherein the content of the C6-C10 fatty acid sodium is 0.9%. The soap flakes of comparative example 2 were prepared in the same manner as in example 1.
The soap chips prepared in the above examples and comparative examples were respectively tested for dispersibility and detergency.
1. Dispersion Performance test and test results
The detection method comprises the following steps: the soap chips (size: 40mm by 40mm, thickness: 0.7 to 0.8mm) obtained in each of examples and comparative examples were put in 1L of water at 25 ℃ and the time required for complete dispersion of the detergent bars was measured using a stopwatch, and the results of the measurement are shown in Table 4 below.
TABLE 4 results of dispersibility test of soap chips of examples 1 to 6 and comparative examples 1 to 2
As can be seen from Table 4, the soap flakes of comparative example 1, in which no instant disintegrator was added, and the soap flakes of comparative example 2, in which sodium fatty acid for ordinary soap was used, gave a product having a much longer dispersion time than the soap flakes of examples 1 to 6, in which an instant disintegrator was added and a specific sodium fatty acid was used. Therefore, the sodium aliphatate and the instant disintegrating agent are adopted in the soap flakes, so that the dispersing time of the soap flakes is greatly shortened, the dissolving speed is higher, and the condition that the soap flakes are adhered to clothes due to insolubility or partial insolubility of the soap flakes in the washing process can be effectively prevented.
2. Stain removal Performance test and test results
The detection method comprises the following steps: according to the GB/T13174-2008 standard of determination of detergency and circular washing performance of the detergent for clothing, three types of dirty cloths of national standard carbon black JB-01, national standard protein JB-02 and national standard sebum JB-03 are adopted for testing, and the test results are shown in the following table 5 (the results are the detergency value relative to standard washing powder).
Table 5 example stain removal performance test results
| Sample (I) | JB-01 dirty cloth | JB-02 dirty cloth | JB-03 dirty cloth |
| Ordinary commercial washing powder | 1.12 | 4.53 | 1.11 |
| Ordinary commercial laundry soap | 1.11 | 1.44 | 1.85 |
| Example 1 | 1.2 | 6.3 | 1.5 |
| Example 2 | 1.25 | 6.5 | 1.7 |
| Example 3 | 1.25 | 6.7 | 1.88 |
| Example 4 | 1.3 | 6.7 | 1.78 |
| Example 5 | 1.25 | 6.6 | 1.7 |
| Example 6 | 1.22 | 6.6 | 1.75 |
In the decontamination performance test, the tested common commercial washing powder is the commercial washing powder with the total active matter content of 15-19%; the ordinary commercial laundry soap tested refers to a commercial laundry soap containing sodium fatty acid in the soap having the following composition: the fatty acid salt consists of saturated fatty acid salt and unsaturated fatty acid salt of C6-C20, the content of unsaturated fatty acid sodium is 19.1%, and the balance is saturated fatty acid, wherein the content of C6-C10 fatty acid sodium is 0.8%.
As can be seen from Table 5, the soap flakes of examples 1-6 have a superior overall stain removal performance to that of a conventional commercial laundry powder, a similar sebum stain removal performance to that of a conventional commercial laundry soap, and a superior overall stain removal performance to that of a conventional commercial laundry soap.
The technical contents of the present invention are further illustrated by the examples, so as to facilitate the understanding of the reader, but the embodiments of the present invention are not limited thereto, and any technical extension or re-creation based on the present invention is protected by the present invention.
