Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 296-575-2 | CAS number: 92797-39-2 Substance obtained by acidic, alkaline, or enzymatic hydrolysis of milk composed primarily of amino acids, peptides, and proteins. It may contain impurities consisting chiefly of carbohydrates and lipids along with smaller quantities of miscellaneous organic substances of biological origin.

Test material
- Reference substance name:
- Protein hydrolyzates, milk
- EC Number:
- 296-575-2

Constituent 1
Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic (adaptation not specified)
- Details on inoculum:
- Fresh activated sludge from a biological waste water treatment plant treating predominantly domestic sewage (Bois-de-Bay, Satigny, Switzerland) was used.
The sludge is collected in the morning, washed three times in the mineral medium (by centrifuging at 1000 g for 10 minutes, discarding the supernatant and resuspending in mineral medium) and kept aerobic until being used on the same day. - Duration of test (contact time):
- 28 d
Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 104
- Sampling time:
- 28 d
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Yogurtene undergoes 104% biodegradation after 28 days in the test conditions. The 10-day window criterion is also fulfilled (20% biodegradation on day 1 and 98% on day 11).
Yogurtene did not inhibit the intrinsic respiration of the inoculum at the test concentration and was therefore considered to be non-toxic to the inoculum at the test concentration.
Yogurtene should be regarded as readily biodegradable according to this test. - Executive summary:
The Ready Biodegradability of Yogurtene was determined by the Manometric Respirometry Test.
Yogurtene undergoes 104% biodegradation after 28 days in the test conditions. The 10-day window criterion is also fulfilled (20% biodegradation on day 1 and 98% on day 11).
Yogurtene did not inhibit the intrinsic respiration of the inoculum at the test concentration and was therefore considered to be non-toxic to the inoculum at the test concentration.
Yogurtene should be regarded as readily biodegradable according to this test.
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).
