A European Union risk assessment report into the molecule dated May 2006 suggested it had potential depigmenting properties and was a potential endocrine disruptor. This was done under its EINECS number of 202-679-0. [ 8 ]
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
Chemical Safety Reports are the main end point for data assessment under REACH (the European Community Regulation on chemicals and their safe use, concerning the Registration, Evaluation, Authorisation and Restriction of Chemical substances [4]) in which hazard and exposure data are considered together to assess the risk of a substance. [5]
The Hierarchy of Occupational Exposure Limits, of which occupational exposure banding is a member. Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health.
A Risk Assessment Report (RAR) conducted by the European Union on sodium hypochlorite conducted under Regulation EEC 793/93 concluded that this substance is safe for the environment in all its current, normal uses. [26] This is due to its high reactivity and instability.
Concise International Chemical Assessment Documents (CICADs) are published by the World Health Organization within the framework of the International Programme on Chemical Safety (IPCS). They describe the toxicological properties of chemical compounds .
Hereafter, an example for calcium sulfate (gypsum, anhydrite) precipitation releasing sodium hydroxide: Na 2 SO 4 + Ca(OH) 2 → CaSO 4 + 2 NaOH. or, the reaction of sodium carbonate with portlandite, also important for the catalysis of the alkali–carbonate reaction as emphasized by Fournier and Bérubé (2000) and Bérubé et al. (2005): [17 ...
Inside the cracks, the water evaporates and the amount of hydroxide keeps increasing progressively. The concentrated area with high stress works as anode and diluted area works as cathode. At anode, sodium hydroxide attacks the surrounding material and then dissolves the iron of the boiler as sodium ferrate forming rust. This causes ...
