Why Chemoris
One form, 24 languages, two regulatory systems
EU and Turkish rules in one tool: an SDS in the target country's language from the same formula.
30
target countries
The 1.4 emergency number and the 15.1 regulatory information follow the country you choose.
16
sections
All 16 REACH Annex II sections are ready, each with its source.
EU + TR
regulations
CLP and REACH Annex II plus the Turkish SEA and KKDIK rules in one tool; classification uses ECHA data.
How it works
From CAS numbers to a Word SDS in three steps
ECHA CHEM data is fetched, the published CLP calculation rules are applied to the mixture and the 16-section SDS is built in Word.
-
Enter CAS and percentage
CAS numbers and percentages are all you need. Name and EC number come from ECHA CHEM; the percentage range in the SDS is calculated.
-
Classification and label
The published CLP calculation rules are applied to the mixture; H statements, pictograms and signal word arrive with their reasoning.
-
Review and download
See the source of each section in the summary, correct what you need to, and download the 16-section SDS draft as Word (.docx).
Sample analysis
See a report without signing up
SDS Check reads an existing sheet section by section and shows where the problems are. The report shown is a fictional sample, not your document.
- Findings in order of severity, with section numbers
- The legal basis next to every finding
- The report does not give the correct value; it shows where the problem is
Features
Chemoris takes on the time-consuming part
You stay in control; the repetitive searching, matching and formatting goes away.
Rule-based and traceable
Every hazard class, pictogram and H/P statement shows which component and which CLP article it came from. You can trace each result to its rule and review it with an expert.
- Summation method and thresholds from the CLP Annex I tables
- Every result can be corrected manually
ECHA CHEM data comes in automatically
Type the CAS number and percentage; substance name, EC number, class, H codes and pictograms are filled from ECHA CHEM. You can see whether the data comes from the harmonised classification or from notifications.
- You enter unregistered substances manually
- Only the CAS number is sent to ECHA
- Component rows can be reordered by drag and drop
Label elements at a glance
Pictograms, signal word and H/P statements are assigned from the mixture classification; the label preview updates as you edit. ADR transport information comes in the same step.
- GHS pictograms and signal word
- P statements chosen by precedence rules
- P statements are editable and sortable by drag and drop
Editable output in Word
The 16-section Safety Data Sheet downloads as .docx in a standard layout. You make the final touches in Word; if you like, your company logo goes at the top of every page.
- Header box and page number on every page
- Forms are stored in your account and can be downloaded again
One formulation, 24 languages
Choose the Türkiye (KKDIK) profile for Turkish or English, or the EU (REACH Annex II) profile for any of the 23 official EU languages. The formulation stays the same; just switch the language and download again.
- Choosing the target country suggests its official language
- H/P statements and section headings use the official EUR-Lex text
- The 1.4 poison centre and 15.1 national legislation follow the country
Component and mixture library
Save frequently used components and mixtures such as perfumes once, with M factor, ATE and specific concentration limit; call them up in later forms with "Add from library".
More features and details
-
Bulk and supplier data import
Add components in bulk from an Excel template, CSV or pasted table; the classification, H codes, M-factors, SCLs and ATEs from a supplier's SDS come in the same way. A CAS number with a wrong check digit is skipped with a warning.
-
Split a mixture into its allergens
Add the perfume with its share; its parts become component rows in proportion, and the same CAS number is summed. The undisclosed remainder stays as its own row.
-
Fragrance allergen declaration
Link the supplier's allergen declaration (PDF or pasted) to the mixture; allergens are calculated in the finished product from the dosage, and those below 0.01 % drop out. Without a declaration the list is marked "provisional".
-
Detergent ingredient declaration
For detergents sold in the EU, the ingredient declaration and allergen list under Regulation 648/2004 are built from the components; bands can be written in the official wording or in short notation (5–<15 %).
-
Only the legally required ingredients in section 3.2
If you wish, table 3.2 is narrowed according to REACH Annex II: water and ingredients without a disclosure duty drop out. Calculations use the full formulation; each ingredient shows why it is listed.
-
Specific concentration limits
Limits from ECHA come in with the component; you define your own limit in the library. The calculation uses this limit instead of the generic threshold.
-
Copy an SDS, keep your edits
Start a new form by copying an existing SDS. Manual corrections made in step 3 are not lost when you recalculate.
-
Label details
The EUH208 sensitiser sentence is added automatically with substance names; a UFI label suggestion appears in 15.1; P101 and P102 are added for consumer products.
- Sign in with email or Google, email verification
- Only you can see your records

Data and rule sources
Substance data comes from ECHA CHEM; classification rules come from CLP Annex I, the format from REACH Annex II and KKDIK.
How we calculate is visible
Next to every class you see the calculated sum and the CLP Annex I table reference; you can check and edit the result.
Not a replacement for the expert
The SDS is prepared and approved by a competent person (in Türkiye, a certified Chemical Assessment Specialist, KDU). Chemoris speeds up the draft and the check; the final decision is the expert's.
Risk-free start
No credit card required; 1 SDS credit free when you open an account. If you have a question, write to us on WhatsApp or by email from the Contact page.
Will it pass an audit?
Chemoris does not approve a document on behalf of any authority; the person who prepares it is responsible for the content and the legal sign-off. With the SDS checker you can see inconsistencies between sections and regulatory errors in an SDS you already have.
What happens to my data?
Form data is stored against your account, other users cannot see it, and you can delete it any time from the My SDSs panel.
Which regulations and languages?
The Turkey profile (KKDIK/SEA) gives a Turkish SDS or an English SDS; the EU profile (REACH Annex II) covers 30 countries and the EU's 23 official languages. Irish is not supported.
What does the output look like?
See a sample SDS with all 16 sections, one by one; no account needed.
FAQ
Frequently asked questions
Are MSDS and SDS the same thing?
Yes. MSDS (Material Safety Data Sheet) is the old name; the international name is SDS (called GBF in Turkey). Chemoris prepares all of them: the same 16-section document, covered in the how to prepare an SDS guide.
How does online SDS (MSDS) software work?
You enter CAS numbers and percentages; Chemoris pulls the data from ECHA CHEM, applies the published CLP calculation rules to the mixture and produces the 16-section document as an editable Word file. No installation; it runs in the browser.
Does the software replace a chemical assessment expert?
No. The software shortens the calculation and drafting time; the preparer remains responsible for the content of the document and for legal approval. For cases that require an expert, see the KDU (chemical assessment expert) guide for details.
Where does the data come from?
From ECHA CHEM: the C&L Inventory (harmonised classification and industry notifications) and REACH registration summaries. The source is shown on every row.
Which rules is the classification based on?
CLP Regulation (1272/2008) and the Turkish SEA Regulation. Component classes are carried to the mixture with the summation method and generic thresholds; where a substance-specific concentration limit (SCL) exists, it takes precedence. The reasoning and legal basis of every result are visible in the classification step.
Can I check an existing SDS?
Yes. Upload the SDS you prepared or received from a supplier (Word or PDF) to the SDS checker and see inconsistencies between sections and regulatory errors. Free with an account, fair use applies.
Can I change the results?
Yes. Every field is editable and download is always available; there is no mandatory approval step.
Can I add my company logo to the document?
Yes. You can upload your logo in the company step and, if you like, also use it as a faint watermark in the middle of the page. Your company details are filled in automatically on later SDSs.
What if I enter a substance that is not registered with ECHA?
You enter the name and class manually. The row is flagged and shown as a warning in the summary step.
Is my data stored?
Form data is stored linked to your account and other users cannot see it; you can delete it from the My SDSs panel.
Are SDSs produced in other languages?
Yes. In the download step you choose the legislation profile. With the Turkish (KKDIK/SEA) profile you download a Turkish SDS or an English SDS. With the EU (REACH Annex II, (EU) 2020/878) profile you choose one of 30 target countries (the 27 EU member states, Norway, Iceland and Liechtenstein) and the output language, which is one of the 23 official EU languages (Irish is not included). Choosing the country suggests its official language and fills 1.4 with the official poison centre and 15.1 with national legislation lines; Romania and Poland have no official number, so a company number is requested. All of them download as Word (.docx).
What are the results based on?
Each result shows the rule it comes from. Each hazard class of the mixture is justified with a CLP (1272/2008) article, and the result comes from the rule list. For details, see the mixture classification guide.
Do I have to write an SDS from scratch manually?
No. The fields fill in automatically; you can edit the output manually in Word. Every field is also editable in the wizard.
Is it free, and what are the prices?
Creating an account and the SDS check are free; a new account gets 1 SDS credit as a gift. Further SDSs are prepared with credit packs, and the prices are listed openly.
Which products is it suitable for?
For mixtures whose components are identified by CAS number. For a single-substance product, the classification comes directly from the substance's record.
Do I need an account to use the tool?
Yes. You need to open a free account with email or Google. Everyone who opens an account gets 1 free credit; the first Word download of each SDS uses 1 credit, while the wizard and preview are free. Details: credit packages.
What is the component library and what is it for?
It is a list where you save frequently used components and mixtures such as perfumes once, with M factor, ATE and specific concentration limit. In later SDSs you call them up with "Add from library" and do not re-enter the same data.
How is a perfume or mixture split into its allergens?
Add the mixture with its share; its parts become component rows in proportion, and the same CAS number is summed. The remainder the supplier does not disclose stays as its own row. This way the allergens enter the mixture classification at their own shares.
How does bulk import with the Excel template work?
Download the template in the Components step, fill in the CAS numbers and percentages, and upload it. Pasting from Excel, CSV or a table is also accepted. A CAS number whose check digit does not match is skipped with a warning.
How do I copy an existing SDS?
Copy the form from the My SDSs panel; it opens as a new form and you edit whatever you want to change.
How are specific concentration limits applied?
Limits from ECHA come in with the component; you can define your own limit in the component library. The calculation uses this limit instead of the generic threshold.
