NEODOL ethoxylates and other NEODOL-based surfactants are used in many of the most respected consumer detergents, cleaning products and personal care products worldwide. In contrast, emulsifiers with HLB values less than 10 are more hydrophobic and therefore better suited for w/o emulsions. Une micelle (nom féminin dérivé du nom latin mica, signifiant « parcelle ») est un agrégat sphéroïdal de molécules amphiphiles, c'est à dire de molécules possédant une tête polaire hydrophile dirigée vers le solvant et une chaîne hydrophobe dirigée vers l'intérieur.
