Frequently Asked Questions
Is Sodium Chlorate safe in cosmetics?
Strong oxidizer; causes methemoglobinemia at systemic doses; hemolytic potential; restricted to hair dyes only in EU; must not be used in oral care or leave-on products The EU classifies Sodium Chlorate as "restricted". Safety rating: POOR. 10 toxicological study endpoint(s) are available in our database.
Is Sodium Chlorate allowed in the EU?
Sodium Chlorate EU regulatory status: restricted. Maximum allowed concentration: 3%. This is based on EU Regulation 1223/2009 and its amendments.
What does Sodium Chlorate do in cosmetics?
Sodium Chlorate functions as: Oxidizing agent. It is classified as a cosmetic ingredient in our database. CAS number: 7775-09-9.
What is the Margin of Safety for Sodium Chlorate?
not established The Margin of Safety (MoS) is calculated using SCCS methodology. A MoS above 100 is generally considered safe. Use the MoS Calculator tool to calculate MoS for your specific formulation and product category.
What is the NOAEL for Sodium Chlorate?
The NOAEL (No Observed Adverse Effect Level) for Sodium Chlorate is 100 mg/kg bw/day based on a oral study via oral route in rat. A total of 10 study endpoints are available. Source: REACH.
Is Sodium Chlorate classified as hazardous under GHS?
Sodium Chlorate carries a GHS signal word of "DANGER". Hazard statements: May cause fire or explosion; strong oxidizer Harmful if swallowed Causes damage to blood and kidneys. This classification is based on the ILO/WHO International Chemical Safety Card and ECHA C&L inventory data. Note: GHS classification applies to the pure substance — at cosmetic use concentrations, hazard thresholds may not be met.
