Water soluble package and liquid contents thereof

摘要

The present invention provides a water soluble package formed from a water soluble film containing a substantially nonaqueous liquid composition, said film comprising a plasticizer system and said liquid composition comprising a surfactant, and at least two different solvents being a primary and a secondary solvent, wherein the liquid composition contains the secondary solvent in an amount of at least 5% by weight of the primary solvent present therein and wherein the main plasticizer in the film is the same chemical as the secondary solvent. Said package was found to have considerably improved strength as compared to packages of the prior art. <IMAGE>
