SDS generator

SDS generator: create a safety data sheet from CAS numbers

Enter the CAS numbers and percentages of your product. Chemoris retrieves ECHA CHEM data, classifies the mixture with the published CLP rules and prepares the 16-section safety data sheet as an editable Word file, with the reason shown for every result.

In short: enter the CAS numbers and percentages of your product. Chemoris retrieves the substance data from ECHA CHEM, classifies the mixture with the published CLP rules and prepares the 16-section safety data sheet (SDS) as an editable Word file, with the reason shown for every result.

How it works: from CAS numbers to a Word SDS

  1. Enter the components. Type the CAS number and the percentage of each ingredient. The name and EC number come from ECHA CHEM, and the concentration range printed in Section 3 is calculated for you.
  2. Classification and label. The CLP mixture rules are applied to your recipe. Hazard classes, signal word, pictograms and H and P statements appear in the preview, each with the component and the rule behind it.
  3. Review and correct. Every field stays editable. The overview shows where each of the 16 sections gets its content, so you can check the points that need your own knowledge, such as exposure limits, stability or the emergency telephone number.
  4. Download. Save the SDS as a Word (.docx) file, with your logo and a watermark if you wish.

What the tool does, and what it does not

Searches for an "SDS generator" or "create SDS online" often lead to template editors that leave the chemistry to you. Chemoris does the repetitive part: fetching the data, applying the mixture calculation and keeping Sections 2, 3, 9 and 14 consistent with each other. The calculation is rule-based, not guesswork: summation and the concentration limits of CLP Annex I are applied the same way every time, and the result can be traced back to its rule.

  • Data source: ECHA CHEM; the page shows whether a classification comes from the harmonised entry or from notifications.
  • Rules: CLP Regulation (EC) No 1272/2008 and the 16-section structure of REACH Annex II (as restated by Regulation (EU) 2020/878); the Turkish SEA and KKDİK rules for Turkish SDSs.
  • Your responsibility: Chemoris prepares the draft. The content of the SDS stays with you as the supplier, and for Turkish GBF documents a certified KDU is still required.

Try it before you sign up

Two parts work without an account. The free CLP label tool turns H codes into a label preview with pictograms, signal word and P statements. The SDS checker shows a sample report on a fictitious document, so you can see how findings are listed by severity with their legal basis. Checking your own file is free with an account and does not use a credit.

Frequently asked questions

Is this an AI SDS generator?

No. The classification is rule-based: Chemoris applies the published CLP mixture rules (summation method and the limits in CLP Annex I) to the data it retrieves from ECHA CHEM. Every hazard class, pictogram and H/P statement shows which component and which rule it came from, so you or your adviser can trace and correct it.

Can I create an SDS from a CAS number alone?

A CAS number identifies a substance, but the SDS of a mixture also needs the percentage of each component. Enter the CAS numbers and the concentrations; the substance name, EC number and hazard data are filled from ECHA CHEM. A substance that is not in ECHA CHEM can be entered manually.

What does it cost to try?

A new account gets 1 free SDS credit, and no card is needed. The wizard and preview are free; packages are on the pricing page.

Does the SDS replace expert review?

No. Chemoris is a tool: it prepares a draft and shows its reasoning, but the supplier remains responsible for the content of the safety data sheet. In Türkiye, a Turkish SDS (GBF) is prepared by a certified chemical assessment expert (KDU) under KKDİK, and Chemoris does not replace that role.

Which file do I get?

A Word (.docx) file with all 16 sections that you can edit, together with the label preview. The document language and the target market are selected in the wizard.
