Sulphated Fatliquor Extraction from Nagkesar (Mesua Ferrea) Seed Oil for Leather Processing

Abstract

Fatliquor improves organoleptic and strength properties of leather. Fatliquor is made from non-edible Mesua ferrea seed oil using the sulphation process by adding sodium hydroxide to fix its pH at 5.0. FT-IR analysis confirmed that strong chemical bonding between oil & sulphonic acid group. Physico-chemical properties of sulphated fatliquor were analyzed and compared with conventional fatliquor. Sulphated Mesua ferrea oil fatliquor revealed to Acid value (35.43), Saponification value (255), Iodine value (76.14), Fatty matter (60.9%), soluble in water (250C), PH :6.1 in 10% solution, stable against salt, tanning and basification agent, odorless and dark brown liquid. Prepared Mesua ferrea seed oil fatliquor is consistent in physico-chemical properties with standard value of fatliquor. As prepared eco-friendly and cost effective fatliquor may reduce dependency on edible oils for conventional fatliquor. Therefore, fatliquor made from Soxhlet-extracted Mesua ferrea seed oil could be used in place of traditional fatliquor in leather processing.
