I need comments, information and technical-scientific references related to toilet soap bars made with soap noodles without glycerol extraction after the saponification step. The noodles are made from either fat/oil or 100% vegetable oils and the focus is in the following properties:
| Item | Description | [ # ] | [ * ] |
| 1 | exudation' – migration of water/moisture on the bars' surface | - 3 | from - 1 to 0 |
| 2 | efflorescence – crystal formation on the bars' surface | -1 | 0 |
| 3 | soap bar texture | 0 | + 2 |
| 4 | lathering – amount and stability | - 1 | + 1 |
| 5 | rinsing from skin | - 1 | + 2 |
| 6 | 'mush' and 'jelly' | - 2 | 0 |
| 7 | cracking | - 2 | 0 |
| 8 | moisturize skin benefit | + 1 | + 2 |
The scale [from -3 to +3] shows the range between the present [#] and the desired condition [*] after rework. How to minimize the negative aspects of glycerol left in the noodle by raw materials and process compromise?
