Abstract

The present disclosure concerns a cosmetic product for modifying the natural color of keratinous fibers, in particular human hair, comprising at least one packaging (VP) and a cosmetic composition (KM) contained in this packaging (VP). The packaging is made of a multi-layer film (F) comprising at least two polymer layers (P1) and (P2) and at least one barrier layer (BS). The cosmetic composition comprises at least one oxidizing agent and at least one thickening agent from the xanthane group. The use of the packaging (VP) in combination with the cosmetic composition (KM) does surprisingly not lead to an inflation of the packaging or an excessive water loss of the agent (KM) during storage.
