Abstract

The present disclosure concerns a cosmetic product for modifying the natural colour of keratinous fibres, 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 multilayer film (F) containing at least two polymer layers (P1) and (P2) and at least one barrier layer (BS). The cosmetic composition comprises at least one oxidizing agent, at least one C8-C30-alcohol, at least one specific anionic surfactant, at least one non-ionic surfactant and at least one acrylic acid-based thickener. The use of the packaging (VP) in combination with the cosmetic composition (KM) surprisingly does not lead to an inflation of the packaging or an excessive loss of water of the agent (KM) during storage.
