A REVIEW: NATURAL COLOURANTS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 7
Abstract
Source of colours from natural sources have been ignored from many years. Less research is done in this field. Natural colourants are used mainly for textile dyeing. Field of application of natural colourants is restricted and market of natural colours is also less. Over the past many years, it has been observed that synthetic dyes have many disadvantages associated with them like toxicity, pollution, allergenicity etc. but natural dyes have no such disadvantages. Indian history is rich in colours from natural resources but no such database is available for exact production of colours from natural sources. In this article we review the use of natural colours from history, their field of application, their advantages and disadvantages.
