Tensioattivi

I tensioattivi aumentano il potere bagnante dell’acqua (cioè la capacità di penetrazione del detergente nei punti altrimenti difficilmente accessibili e all’interno delle particelle di sudiciume) in modo da rimuovere le particelle dalla superficie e portarle in sospensione. Essi sono composti da una parte idrofoba (che si lega allo sporco organico ma non all’acqua) e da una parte idrofila (che si lega all’acqua ma non allo sporco organico) facendo così passare le micelle nel solvente (solubilizzazione).
Sono classificati in:
I tensioattivi hanno diverse azioni :
