| Résumé : |
The emulsifier system showed a pronounced influence on the antimicrobial performance of a surfactant and organic acids based preservation system. Emulsifier blends comprising hydrocarbon moieties showed a negative influence on the antimicrobial performance of the tested perservation system. Anionic emulsifiers have a tendency to support the preservation activity better than non-ionic emulsifiers.
It is important to understand that most ingredients have an influence on the product preservation. This influence can be favourable or detrimental. It cannot be assumed that even a slight change of a formulation or the variation of the dosage of a component does not alter the result of the preservation performance. Challenge tests need to be performed in order to proof sufficient preservation after each change in a formulation composition. |
