摘要:
A process for synthesizing 2-methoxymethyl-1,4-benzenediamine, its derivatives of formula (IV) and the salts thereof, which comprises a reductive amination step. The preferred final product is 2-methoxymethyl-1,4-benzenediamine of formula (IV-a). These compounds may be used as primary intermediates in compositions for dyeing keratin fibers.
摘要:
The present invention relates to personal care compositions, especially those personal care compositions in the form of a personal care article that is a porous dissolvable solid substrate. The porous dissolvable solid substrate has a surface resident coating comprising a water sensitive active that can deliver a consumer benefit.
