Process for dampening foaming of a liquid which employs a compound of the formula R(3-x)PO(OH)x OR AN ALKALI METAL OR AN ALKALI EARTH METAL SALT THEREOF AS FOAM-DAMPENING AGENT, R being CnF2+1, n being an integer from 4 to 24 and x being 1 or 2. The compounds used as foam-dampening agents have excellent stability with respect to heat, acid and oxidation influences, and may be applied in the pH range of 1 to 12. |
