Content:
The wastewater after the fatliquoring process contains the surfactants, neutral salts and unspent or unbound oil. This is predominantly attributed to the manner in which fatliquors are prepared. The oil in
water emulsions (fatliquors) are prepared through chemical modification of oils along with surface active agents that would enhance the dispersion of oil in water. The discharged chemical compounds from the
post tanning process are likely to exist as persistent organics in the soil.
In this paper, an ambitious effort to take forward the successful lessons from other sectors such as healthcare is presented. The use of liposomes as oil carriers has been envisaged. For this, the
lacunae associated with liposomal carriers such as stability, encapsulation efficiency, the release of payload under desired conditions etc. has been addressed. The study focuses on stabilizing the liposomes
and the triggered delivery under the drum pH conditions. A liposomes -biopolymer composite based on Egg Phosphatidyl Choline and Pectin encapsulating oil, has been prepared. Using spectroscopic and
colorimetric techniques the presence of biopolymer in the composite, encapsulation of oil and stability over a range of pH conditions has been investigated. The biopolymer influences the stability and oil
encapsulation efficiency of the composite in a concentration-dependent manner. To understand the release of oil in a pH dependent manner, the oil was substituted with a model dye and its release under a
narrow pH span was observed, indicating that the oil could be released to fibers by modulating the pH. I nitial studies relating to the potential of this product as a possible fatliquor is encouraging.
Take-Away:
A stabilized liposomal systems encapsulating oil as a delivery vehicle to deliver its contents under the triggered pH conditions is described.
Biopolymer, induced stability and ensures the oil encapsulation in the bilayer region for the composite vesicles.
The work initiates a step towards developing fatliquors based on biodegradable materials, avoiding the emulsifiers and conventional route to make oil in water emulsions.
