Re-launch of optimized acid cellulases package for Bio-Polishing application

1.1.1.1. Introduction and ConceptIntroduction and ConceptIntroduction and ConceptIntroduction and Concept

This marketing information presents the following optimized products:

Lava Cell BTS Lava Cell BTS conc Lava Cell BLK

Bio-Polishing is a controlled hydrolysis of cellulosic fibers to modify the fabric in a manner that reduces the pilling tendency and

increase the smoothness and softness of the finished fabric.

Usually, the Bio-Polishing process is applied in acidic conditions (pH 4.5-5.5) at 50 - 55 C just after the scouring or bleaching

process and before dyeing.

This well-known acid enzymes market is mature and highly competitive. In this case the cost/performance ratio is the dominant

factor.

Thanks to the new enzymatic formulations that improve in a significant way our current offer for the Bio-Polishing segment we

launch this new product package to cover this important market segment with success.

The new improved cost of these products will enable us to be much more competitive in the market segment of acid cellulases

for Bio-Polishing and therefore win market shares.
