Definitions
- active oxygen has been used for bleaching chiefly in the form of hydrogen peroxide-solutions, except with soaps and oils that are bleached by means of per-sulphate or benzoyl peroxide.
- Bleaching by perborate or similar agents is practically a hydrogen peroxide bleaching process, since these chemical compositions split off hydrogen peroxide when dissolved.
- Example -phate of ammonia, feat-hers or hair may be leached and become bright within a few hours without affecting the article to be bleached.
- the bleaching efiect is accelerated and increased in many cases by ex osing the article to be bleached to the light uring the bleaching process, whereby the bleaching process may take place either in the bleaching bath itself or in the open air, in the latter case after the article has been soaked with the above mentioned solutions.
- a bleaching bath comprising hydrogen peroxide and a persulphate.
