Abstract
A deinking composition is used for reclamation of waste paper and comprises (a) an alkylene oxide adduct to a mixture of a natural oil or fat and a polyhydric alcohol and (b-1) an alkylene oxide adduct of a higher alcohol, (b-2) a sulfate of (b-1) or (b-3) a higher fatty acid.
Claims7
A deinking composition for reclamation of waste paper, which consists essentially of (a) a reaction product obtained by adding one or more alkylene oxides to a mixture of a natural ol or fat and a polyhydric alcohol and (b) a compound selected from the group consisting of (b-1) an alkylene oxide adduct of a higher alcohol having the formula (1):
- R--O--AO).sub.n H (1)
- in which R is an alkyl or alkenyl having 12 to 18 carbon atoms, AO are units derived from ethylene oxide or ethylene oxide and another alkylene oxide having 3 to 4 carbon atoms and n is 5 or more on the average, (b-2) a sulfate of an alkylene oxide adduct of a higher alcohol having the formula (2):
- R'--O--A'O).sub.m SO.sub.3 M (2)
- in which R' is an alkyl or alkenyl having 10 to 18 carbon atoms, A'O are units derived from ethylene oxide or ethylene oxide and another alkylene oxide having 3 to 4 carbon atoms, m is from 0.3 to 5 on the average and M is hydrogen, an alkali metal or ammonium, mixtures of (b-1) and (b-2), and (b-3) a higher fatty acid having 8 to 22 carbon atoms or a salt thereof, wherein the weight ratio of (a) to (b) ranges from 99/1 to 50/50 when (b) is (b-1), (b-2) or mixtures thereof, and from 95/5 to 30/70 when b is (b-3).
