Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 266-113-4 | CAS number: 66071-94-1 Substance obtained by the partial removal of water from the liquid resulting from steeping corn in a water and sulphur dioxide solution which is allowed to ferment by the action of naturally occurring lactic acid-producing microorganisms.

Description of key information
In accordance with section 1 of Annex IX, the activated sludge respiration inhibition testing (section 9.1.4.) does not need to be conducted as corn steep liquor (CSL) consists of all-natural, water soluble components (crude proteins, amino acids, minerals, vitamins, reducing sugars, organic acids, enzymes and other elemental nutrients), that have been extracted by soaking corn in water, along with a very small amount of sulfurous acid (<0.01%). CSL has a long history of safe use as an added source of nutrition in animal feed, in fermentation processes, and in antibiotic production. As well, CSL is readily biodegradable. On this basis, CSL is not expected to cause adverse toxic effects to the environment.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
