<p>It is possible to obtain solutions with a high acetate concentration of N-coco-, N-olyelyl- or N-tallow propylene diamines which can be diluted without forming gels or lumps in a water/dissolving agent solvent. A simple dilution test is carried out in order to select the appropriate compositions. The invention also relates to the use of the diluted solutions thereof, especially for the lubrification of bottles on conveyor chains.</p> |
