| Résumé : |
A series of sulfoethyl locust bean gum derivatives with a degree of substitution (DS) ranging from 0.05 to 0.33 was prepared by etherification of locust bean gum with vinylsulfonic acid sodium salt in alkaline 2-propanol suspension. The derivatives were characterized by means of FT-IR and elemental analysis, and evaluated for laundry anti-redeposition performance, alone and in systems with mannanase and/or cellulase enzymes. Optimum anti-redeposition performance was observed at degrees of substitution of around 0.15. Mannanase was found to have a negative effect on sulfoethyl locust bean gum derivatives’ performance although a system comprising sulfoethyl locust bean gum derivative and cellulase was found to be complementary. |
