Our services

Open Science

We provide hazard values for +5,000 chemicals used in the industry. Models are based on latest scientific knowledge while limitations are clearly documented.

Chemicals and LCA expertise

We support public and private stakeholders by providing expertise and tools for specific environmental chemistry use cases.

Historical projects (non exhaustive) : 
– Predicting biodegradability and ecotoxicity of sunscreen formulations for the cosmetics industry;
– Defining and assessing the ecotoxicity of chemicals used in the textile industry for the French administration (LCA context).

Frequently asked questions

How do you calculate hazard values ?

We aggregate validated toxicity data and apply harmonised methods inspired by regulatory risk assessment.
No black box, everything is documented.

Can I integrate my own test results ?

Yes, you can integrate your own data as long as methods and endpoints are clearly documented. This helps refine hazard values and reduce uncertainty.
Your data remain under your control.

Can you assess the toxicity of my products ?

We don’t replace regulatory assessments, but we help screen and compare the environmental hazards of ingredients, formulations and products.

What are your main use cases ?

Early-stage screening of chemicals for environmental hazard and safer alternatives.

How can I contribute to the project ?

Scientists and companies can help improve OpenChemFacts by sharing relevant data or providing feedback on the method and platform.
A dedicated tool is available to compile contributions for active users.
