Shri Ram Products is an ISO 9001 : 2015 certified textile and dye auxiliary chemicals manufacture and exporter, since 1983. Optical brightening agent in our portfolio is a special kind of dye used in a vast number of material, for instance plastic, textile, paper and paint. OBA appears to be lime yellow, fine powder works to make the product appear brighter and cleaner. Yellow tinge is generally removed by a blue shaded agent, but that also leaves a blue tinge on the fabrics. This problem can be solved with the use of OBA to make clothes sparkle bright with absolutely no blue tinge.
