Frequently asked questions
Should you start from H-statements?

Is pH alone sufficient?

Does a general answer validate a specific product?
No. The actual composition, form, supplier data and intended use must be assessed.
Who should approve the result?
A competent person should review the data, method and internal consistency before supply.
