Benefits of technology

[0006]The present invention relates to a method of maintaining chemical reactivity of an oxidative hair dye component while being stored in an opened flexible sachet by increasing the user compliance with the re-closure step of a usage regime of said oxidative hair dye component. This is achieved by providing a sachet where it is folded into its re-closure configuration already as provided before opening the sachet. This causes the

Abstract

The present invention relates to a method of maintaining chemical reactivity of an oxidative hair colorant in an opened flexible sachet including a reclosure element. The quality of the re-closure will strongly influence how the hair colorant will perform when using it as intended. The method according to the present invention ensures maintaining chemical reactivity by improving the quality of the re-closure by intuitively inducing safe and tight re-closure by users of such hair colorant. This is achieved by providing the sachet to the user in a configuration already in its re-closure position, while the sachet has not been opened yet.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method of maintaining chemical reactivity of an oxidative hair colorant in an opened flexible sachet, which is stored for some time. The reason to store such an opened sachet is that prior to use of an oxidative hair color the ingredients need to be tested to ensure they have no adverse reaction by users. This is often done by using a small amount of the product for a skin test, which requires opening of the sachet, and extracting a small sample for the skin test. It is of course important to ensure that the sachet is closed again after extracting the sample to prevent premature oxidation. The quality of this re-closure will strongly influence how the hair colorant will perform when using it as intended. The method according to the present invention ensures maintaining chemical reactivity by improving the quality of the re-closure by intuitively inducing safe and tight re-closure by users of such hair colorant. This is a...
