Abstract: The invention concerns a process to convert di-rhamnolipid to mono-rhamnolipid, using an ?-L-rhamnosidase enzyme which has a sequence identity of at least 70% with either SEQ ID. 1 or SEQ. ID 2.

Abstract: The invention concerns a process to convert di-rhamnolipid to mono-rhamnolipid comprising the following process steps: —(a) contact of a starting di-rhamnolipid material with an ?-L-rhamnosidase enzyme which is immobilised on a support; (b) separation of the produced mono-rhamnolipid from the reaction medium and/or side products; wherein the ?-L-rhamnosidase enzyme does not have ?-D-glucosidase activity.

Abstract: A process for preparing a dispersion of encapsulated solid particles in a liquid medium is described, which includes providing a dispersion comprising solid particles, a liquid medium and a polymer comprising at least one repeat unit of the Formula (1) or a salt thereof: and cross-linking the polymer, wherein X, Q1, Q2, Q3, A and m are as defined.

Abstract: A process for ink jet printing an image on a substrate is described, which includes applying to the substrate a composition including a liquid medium, a pigment and a polymer having a chain of the Formula (1) or a salt thereof: wherein X, Q1, Q2, Q3, A, m and n are as defined, and the polymer having a chain of Formula (1) or salt thereof is used to comminute the pigment.
