Introduction

It is essentially a mixture of low molecular weight polypeptides, in the form of powder, prepared by digesting keratinous proteins with alkali, followed by concentration and spray drying. It has potential use as retaining agent as well as filler in leather processing industry. It's use in rechroming operation improves the exhaustion of chrome. Considering its better compatibility in comparison to the conventional synthetic leather fillers because of its proteinous nature, a wide market potential is envisaged for this product for the upgradation of the lower grades of leathers by selective filling to ensure imparting fullness.
