The present invention describes compositions comprising at least one compound chosen from hydroquinone and catechol, characterised in that it further comprises between 0.1 and 10,000 ppm of at least one compound chosen from 2-(alkoxy)phenol, 4-(alkoxy)phenol, 2-(alkyl)phenol, 4-(alkyl)phenol, (alkyl)catechol and (alkyl)hydroquinone. Another aspect of this invention concerns a method for preparing a composition comprising at least one compound chosen from hydroquinone and catechol according to the invention, characterised in that it comprises a step (a) of reacting the phenol with hydrogen peroxide in the presence of a catalyst, in a solvent comprising an alcohol.
Article of footwear
The present invention is directed toward an article of footwear with an improved eyelet system independent of the upper. The article of footwear includes an upper and a sole structure, where the sole structure includes a top surface, a bottom surface, a lateral side and a medial side. The article of footwear further includes an eyelet system coupled to the top surface of the sole structure. The eyelet system includes a base structure and a plurality of looped strand portions coupled to the base structure. The base structure is coupled to the top surface of the sole structure such that the plurality of looped strand portions extend outwardly from the sole structure, enabling the looped strand portions to receive a fastening element.
