Abstract
The application relates to a packaging system for a hair coloring product containing: i) at least one container (102) holding a composition comprising at least one hair colorant, said composition forming or intended to form a hair coloring product; and ii) at least one test device (20) designed to perform a patch test and incorporating a tube (21) delimiting an internal space containing a dose of said composition, the tube incorporating an outlet aperture (29) and being arranged to cause said composition to be expelled from said outlet aperture (29) in response to excess pressure within the internal space of the tube or when the latter is vented via at least one passage separate from the outlet aperture (29).
Claims16
Hair coloring system (1) comprising:
- i) at least one container (102) holding a coloring composition forming or intended to form a hair coloring product;
- and
- ii) at least one test device (20) designed to perform a test and incorporating a tube (21) delimiting an internal space containing at least one hair colorant of said coloring composition, the tube incorporating an outlet aperture (29), the test device (20) being arranged in a manner such that the contents of the tube are expelled from said outlet aperture in response to excess pressure within the internal space of the tube or when the latter is vented via at least one passage (22) separate from the outlet aperture (29).
Use of a test device (20) including a tube (21) delimiting an internal space containing:
- i) either at least one direct colorant,
- ii) or at least one hair colorant and at least one compound chosen from solvents and surfactants,
- iii) or at least one oxidation base and/or at least one coupling agent,
- the tube having an outlet aperture (29), the device being arranged so that the contents of the tube are expelled via said outlet aperture in response to excess pressure in the internal space of the tube, or when the latter is vented via at least one passage (22) separate from the outlet aperture (29),
- for testing the sensitivity of a subject, prior to a hair treatment with a hair coloring product.
