cotton cloth after bleaching and as a scouring aid for cotton cloth. In the tanning industry, it is used for leather
treatment, which can make the leather soft, plump, tough, waterproof, anti-folding, and wear-resistant. In the chemical
industry, it is used to produce hydroxyvanillin, hydroxylamine hydrochloride, etc. The photosensitive industry is used as a
developer, etc.
