	Sodium Percarbonate::CHEM-ONLINE.org::
		Sodium percarbonate (Synonyms: sodium carbonate peroxyhydrate, sodium carbonate peroxide, PCS) is a free-flowing powder with a common name of solid hydrogen peroxide, it is an addition compound of sodium carbonate and hydrogen peroxide.
		Sodium percarbonate is increasingly being the substitute for sodium perborate in detergent formulations due to its lower dissolving temperature in water, as well as the characteristic of no contamination on soil, as sodium perborate is made of borax which is found to have negative impact on the soil quality.
		Sodium percarbonate is an attractive perhydrate for use in detergent compositions because it dissolves readily in water, is weight efficient and, after giving up its available oxygen, provides a useful source of carbonate ions for detergency purposes.

	Risk Assessments (Site not responding. Last check: 2007-11-04)
		Because sodium percarbonate dissociates into sodium, carbonate and hydrogen peroxide, the environmental risk assessment is based on the risk assessment of the individual components.
		Sodium has a low toxicity and the emitted amount of sodium is relatively low compared to background concentrations and therefore the emitted amount of sodium will not have an effect on the aquatic organisms of the receiving water.
		With regard to genotoxicity and carcinogenicity the properties of sodium percarbonate also resemble those of hydrogen peroxide and it can be concluded that there is no concern for humans with regard to a possible genotoxicity or carcinogenicity of sodium percarbonate.
