Abstract
A packaged effervescent product is provided which includes a sachet surrounded by an outer package film sealing the sachet against water vapor transmission. The sachet is a cosmetic article which includes an effervescent cleansing composition of an acid material such as citric add and an alkaline material such as sodium bicarbonate. The composition is held within the sealed sachet or pouch. At least one wall of the pouch is water permeable. The outer package film is formed of a material which must have a breathability for carbon dioxide. Any carbon dioxide generated during storage is thereby allowed to slowly diffuse into the atmosphere while still minimizing the amount of water which may enter the package.
