Si la réaction de solvatation n'est que superficielle, on obtient une suspension colloïdale, ou une gelée, suivant que le corps est mouillable ou gonflable (hydrophile). En fait, la peptisation, qui est l'expression correspondant à la dissolution colloïdale, est toujours précédée d'un gonflement de la matière solide par le liquide.
