Your in silico expert
We offer our services to screen the hazard of your substance, complete your regulatory dossier, boost your R&D and reduce tests on animals in the most time and cost efficient way possible.
We exist to understand the mechanistic interactions between chemical and biological matrices and quantify the impact on human health and the environment.
La French Touch by KREATiS
We are proud to be one of the first French company to work for the 3Rs, with members from different companies who fight to re-think experimentation.
4 pillars of our activity
The combination of our unique tools will help you to fill your datagaps with the best in silico study predictions available, meeting the 5 OECD principles for the validation of QSARs and regulatory format requirements for a host of dossier submissions and updates notably for REACH and CPSR, ICH M7, Medical devices, but increasingly for aspects of Plant Protection Products, Biocides and Pharmaceuticals.
In silico consulting
Support with Regulatory documents iSafeRat® & for third-party tools for endpoints requiered in dossier submissions.
The power of KREATiS in silico predictions
0
Vertebrate animals saved by the work of KREATiS using in silico methods instead of animal experimentation.
Estimation based uniquely on the number of acute and chronic fish toxicity studies realized by KREATiS from 01/2014 replacing 42 fish in acute OECD 203 and 80 fish eggs in chronic OCDE 210 in vivo studies.
The expertise of model developers
Simply obtaining a prediction is the easy part but having confidence in the reliability of the result requires experience in modelling using multidisciplinary approaches, in silico good practice and unbiased scientific and mechanistic interpretation.
We take pride in sharing our knowledge with you to help you obtain information for your regulatory needs, thanks to our homegrown tools.
iSafeRat® toolbox
iSafeRat® (in silico Algorithms For Environmental Risk And Toxicity) is the KREATiS-made toolbox of High Accuracy QSAR (HA-QSAR) modules produced by KREATiS to replace all kinds of experimental studies related to human health and the environment.
MechoA
MechoA (Mechanisms of toxic Action) MechoA is a structural alerts-based decision tree to predict the mechanisms of toxic action of a large range of chemical structures in different biological species.
It has been developed in collaboration with Unilever and Liverpool John Moores University, becoming MechoA+, which is made freely available in the OECD QSAR Toolbox.
MechoApedia
Open the door to a clear scientific explanation and better understanding of the mechanisms of toxicity action. KREATiS has designed this interactive pedagogic free tool presenting the different MechoA classes.
Endpoints predictions
Our experts offer expert advice based on our in-house software iSafeRat® and third party software packages to predict toxicology, ecotoxicology and physical chemistry endpoints for all kinds of regulatory and R&D needs.
Physicochemical endpoints
- Octanol/Water partition coefficient (log Kow)
- Water solubility
- Vapour pressure
- Henry’s law constant estimation
Ecotoxicological endpoints
- Acute fish toxicity
- Acute daphnid toxicity
- Algae toxicity
- Chronic fish toxicity
- Chronic daphnid toxicity
- Aquatic toxicity for mixtures
- Toxicity to microorganisms
Toxicological endpoints
- Skin irritation
- Eye irritation
- Skin sensitisation
- Dermal absorption
- Endocrine Disruption potential (ED SAR, SESAME-3D and Third-party tools)

“The QSAR estimate for water solubility as well as an estimate for the chronic Daphnia toxicity for a difficult to test substance was our first collaboration with KREATIS. I appreciated the scientifically well-founded communication, always in a timely manner. All documents were carefully prepared and timelines fully met. It was a very good start and I’m looking forward to any further collaboration with KREATIS.”

“I have to say you did a good job with the interface and the report functionality of iSafeRat® Desktop v1.0. Very clear and intuitive, which made it easy to reproduce the results and document it.”
Doris Hirmann,
ECHA Computational Unit
“We work regularly with KREATiS to further the science in R&D projects and as a complement to our empirical ecotoxicity studies especially for mixtures. We believe that the combined approach of using laboratory and in silico approaches in aquatic toxicity studies on mixtures (known as WAF tests) is the best way to scientifically justify the WAF method in regulatory use: The empirical laboratory result validates the in silico prediction; the thermodynamically determined in silico prediction mechanistically explains the laboratory result.”
Nicolas Delpit, Study Director Ecotoxicology;
Sylvie Betat Head of Unit
“In recent years Environment and Climate Change Canada (ECCC) has been profiling new and existing substances for mechanisms and modes of action both for substance prioritization and risk assessment.
Similar concepts found in the MechOA module in iSafeRat were also developed for version 2.0 of ECCC’s Ecological Risk Classification (ERC) system for prioritizing organic substances for further evaluation in Canada. ECCC therefore has a good understanding of the approaches used in iSafeRat for MechoA determination.
We have found that iSafeRat offers one of the few up to date software packages that can link MechoA profiling to high quality QSAR predictions. The detailed information provided in model output with respect to domain of applicability and prediction confidence provides transparency and improves regulatory acceptance and application of results.
The continued effort by the model developers to expand and improve the MechoA and QSAR aspects of iSafeRat is also a key aspect of ECCC’s support for the software.”

“The iSafeRat® toolbox offers both ease of use and high accuracy results.
We rely on the tool extensively for multiple applications within Mane:
- First, to produce study predictions as stand-alone values for submission of regulatory dossiers at home and abroad but also to define testing strategies;
- Second, to define strategy for new substances
- And third, to hunt out lower quality laboratory studies in our database so we can repeat them, if necessary ensure that only the very best data are available for Mane’s products.”
