The invention concerns chemical compositions in the form of pellets which
disintegrate quickly and efficiently in aqueous media. Such pellets
comprise a) at least one constituent with pharmaceutical, agrochemical,
water treatment, water softening, fabric softening or detergency
activity; b) one or more disintegration agents comprising one or more
cross-linked polyacrylate water absorbent polymers with a gel-formation
time of 30 seconds or less and c) one or more water transport agents to
transport water into the pellet when the pellet contacts water, wherein
at least one of the said water transport agents comprises at least one
starch or starch derivative.
