Hydrochloric acid (HCl) is commonly used for the neutralization of alkaline agents, as a bleaching agent, in food, textile, metal, and rubber industries. It is neutralized if released into the soil and it rapidly hydrolyzes when exposed to water. Transport through soil may contaminate groundwater and will dissolve some of the soil materials. Exposure to HCl gas or solutions of HCl may cause eye irritation and permanent damage with loss of sight. Dermal exposure may cause burns. Inhalation of HCl immediately causes severe irritation with cough and choking sensation. HCl is not classifiable as to its carcinogenicity to humans.

Hydrochloric Acid
- Bleaching powder is a pale yellowish powder existing with a strong smell of chlorine.
- It is soluble in water but due to the presence of impurities, we never observe a clear solution.
- Its chemical formula is Ca(OCl2) with its chemical name Calcium hypochlorite.
BACKGROUND OF THE INVENTION
Every construction is unique in scope, but process is systemically applied to each construction project.
The invention relates to a process for the preparation of bleaching granules containing a solid, water-insoluble organic peroxy acid, a hydratable inorganic material, and, optionally, a water-insoluble organic compound and a surface-active compound. The bleaching agents according to the invention may be used alone or as additives in all the usual fields of application for bleaching agents. Preferably, they are employed in detergent and bleaching compositions for textile laundering processes.
