  • the stirrer is switched on for 30 seconds.
  • the sample is transferred to a 100 mL graduated cylinder.
  • a phase separation takes place in which settles an aqueous phase at the bottom of the cylinder.
  • the volume of this newly forming phase is measured in milliliters as a function of time.
  • formulation 1 shows the best emulsion stability and thus the agent used the highest emulsifying ability.
  • formulation 2 shows the best emulsion stability and thus the agent used the highest emulsifying ability.
  • formulation 4 coagulate very quickly.
  • the incorporation of the thickener causes a significant improvement in the emulsion stability (Comparison of Recipes 1 and 2).
  • the addition of surfactant B improves the stability of the emulsion again (Comparison of Recipes 1 and 3).
  • a system without surfactants only with thickening agent separates in the fastest time and thus has the lowest emulsifying capacity (formula 4).

Abstract

L'invention concerne des produits de nettoyage et d'entretien présentant un système de tensioactifs qui comprend au moins deux tensioactifs non ioniques A et B possédant des structures chimiques différentes mais pouvant être représentés tous deux par la formule suivante R1O-[CH2CH(R2)O]X-R3, dans laquelle R1 et R3 représentent indépendamment de l'autre H ou un groupe hydrocarbure aliphatique ou aromatique, saturé ou insaturé, linéaire ou ramifié comportant 1 à 30 atomes de carbone, pouvant contenir jusqu'à 6 fonctions hydroxyle et/ou 3 fonctions éther, un des groupes R1 et R3 ne représentent pas H; R2 représente H ou un groupe méthyle, éthyle, n-propyle, iso-propyle, n-butyle, 2-butyle ou 2-méthylbutyle, les groupes R2 pouvant être différents lorsque x = 2, et x étant supérieur à 1. Lesdits produits de nettoyage et d'entretien comprennent également un épaississant et possèdent un pH inférieur à 6 lorsqu'ils se présentent sous la forme d'une solution à 1 % en poids dans l'eau (20?C). Ces produits de nettoyage et d'entretien selon l'invention présentent une meilleure émulsibilité vis-à-vis des corps gras et des huiles.
