Encapsulated tinters

摘要

A tinter dosage unit comprising water borne tinter encapsulated in a water soluble pouch where the water activity of the tinter and the combined water activity and plasticizer activity of the pouch are such that the pouch remains intact in normal use. The water soluble pouch may be a water soluble fire e.g. a polyvinyl alcohol film. The tinter may comprise humectant, ionic surfactant, and coloured and/or filler pigments.
