| description | The propose to study paraffin-water-surfactant was to obtain emulsions that can selfdisperse in water, and which can be made through a low-energy mixing procedure. A first emulsion formulation was carried out with different Tween and Span surfactants, as well as a mixture for obtaining the W/O emulsions (water in oil). Subsequently, a second emulsion formulation was fulfilled, but this time changing the Hydrophilic-Lipophilic Balance (HLB) and/or moderately changing the surfactant or water percentage. Afterwards, the drop size and the stability were studied, and it revealed that more stable emulsions are obtained in thesystems aforementioned using larger amounts of surfactants and a HLB 8. |

A first emulsion formulation was carried out with different Tween and Span surfactants, as well as a mixture for obtaining the W/O emulsions (water in oil). Subsequently, a second emulsion formulation was fulfilled, but this time changing the Hydrophilic-Lipophilic Balance (HLB) and/or moderately changing the surfactant or water percentage. Afterwards, the drop size and the stability were studied, and it revealed that more stable emulsions are obtained in thesystems aforementioned using larger amounts of surfactants and a HLB 8. Se estudió el sistema de parafina-aceite-surfactante con la finalidad de obtener emulsiones que tuvieran la capacidad de ser autodispersables en agua y se realizaran con un método de mezclado de baja energía. Se realizó un primer barrido de formulación con diferentes surfactantes de la línea tween y span, así como las mezclas de los mismos, para la obtención de emulsiones de tipo W/O (agua en aceite, por sus siglas en inglés). Seguidamente se realizó un segundo barrido de formulación variando el HLB y/o ligeramente el porcentaje de surfactante o el agua empleadas. Posteriormente, se estudió el tamaño de gota y la estabilidad, demostrando que en los sistemas estudiados se obtienen emulsiones más estables con altas cantidades de surfactante y un HLB de 8.
