NEWS Innospec passes tests
Innospec has revealed that it has successfully tested the biodegradation performance of its isethionate and taurate surfactants under aerobic and anaerobic conditions, using a series of internationally standardised screening level tests. These range from OECD 301A-F (Ready Biodegradability under Aerobic Conditions) to OECD 311 (Anaerobic Biodegradability of Organic Compounds in Digested Sludge). In the former, the surfactants
were incubated for 28 days in a mineral medium containing an inoculum of microorganisms. The degradation of the test substances over time was measured using CO2 (OECD 301B) or O2
uptake (OECD 301D) as an indicator
by measuring the increase in headspace pressure in the test vessels and the proportion of the CO2
dissolved in the aqueous
phase or transformed into carbonates was also measured. The surfactants tested
of complete biodegradation to water, CO2
and nutrients.
Positive control and reference substances were included in the test for validation and to prove the viability of the inoculum. For the OECD 311 tests,

washed and diluted digested sludge was incubated together with the individual surfactants in a mineral test medium for 60 days in sealed vessels. The production of CO2

showed an “impressive performance” in both tests, the company said. All met the criteria for classification as readily biodegradable in accordance with the OECD 301 guidelines. SLMI was found to be
anaerobically biodegradable in accordance with OECD 311, which also applies to SLI on the basis of read-across. SMOT was clearly anaerobically biodegradable under the OECD 311 test conditions where it actually outperformed the positive control.
Full Circle has introduced its latest active based on brewery by-products. Barley Toniq is enzymatically extracted, leading to a concentrated mixture of carbohydrates, short-chain proteins and polypeptides. It is preserved with a microbiome-friendly grade of propanediol which comes from an upcycled, non-GMO feedstock.

largely attributed to its high amino acid content, including eight of the nine that are known to help reduce the appearance of irritated skin and boost the skin’s barrier function. Barley Toniq is also highly potent and so can be incorporated into skincare formulations at use levels as low as 1%, Full Circle added.
Two more milestones for Gattefossé
Gattefossé has revealed that in October 2021, following two years of work, it obtained ISO 14001:2015 certification for its main production site in Saint-Priest, France. Shortly afterwards, the site also received a Platinum award from EcoVadis for its CSR performance. “The implementation
of this environmental management system, now certified, aims to continuously improve the company’s performance through a more sustainable use of resources and the reduction of waste. Gattefossé is committed to a continuous improvement process in order to maintain

this certification for the next few years,” the company stated. The Platinum award, giving
the company a score of 74 out of 100, four up from 2020, places it among the top 1% of companies evaluated by EcoVadis, on the themes of Environment, Social & Human Rights, Ethics and Responsible Purchasing. Gattefossé attributed this
to the various actions it has implemented on improving the
traceability, sustainability and performance of raw materials, reducing direct and indirect carbon emissions, and working on the eco- design of ingredients. It also uses EcoVadis to assess the CSR performance of all its suppliers. “Today, these two

recognitions allow us to illustrate our ambitions. ISO 14001 is a great structuring tool that will help us to achieve our strategic objectives, by taking environmental issues into account even more strongly in the management of the company,” said Laurent Schubnel Gattefossé’s CSR group leader.
