Leather lubricants. Part V. liquouring properties of certain non-edible oils

Abstract

Fatliquoring properties of sulphated maroir oil (Hydrocarpus species) and illipe oil (Madhuea lalifolia/ longifolia) were studied. Leather fatliquoring with sulphated maroti oil has hard feel; sulphated products or blends of this oil with pungam oil has soft well lubricated feel.IIlipe oil alone produces a sulphated fatliquor which is "soft soap" like in nature at room temperature, but the product emulsifies with hot water and lubricates leather well; fatliquored leather has smooth wax-like surface feel. The consistency of the fatliquor can be changed into liquid or thick cream by preparing sulphated product of the blends of illipe oil and pungam or castor oil or by sulphating transesterified product of illipe oil and a polyol ; these products fatliquor leather well.
