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 comprising a surfactant and a primary solvent, wherein said primary solvent is a diol having a hydrogen-bonding Hansen solubility parameter (as defined herein) of greater than 20, and wherein the hydroxyl groups present in said diol are terminal hydroxyl groups, whereby the distance between these groups is 3 carbon atoms. Said package was found to show both favourable film strength and flexibility and good solubility of the liquid contained therein.
