How to use the SIN List

The SIN List is a perfect starting point for any organisation committed to identifying and substituting hazardous chemicals in products and processes with safer alternatives.

The SIN List is more than just a list of chemicals. It is a tool to facilitate chemicals management. In addition to the chemical identity the SIN list provides for each chemical, it also gives you information on REACH status, use and function, concerns, production and available alternatives.

Use this information to identify, prioritise and substitute SIN List chemicals from processes and products.


Where to start?

The SIN List is long – it contains about one thousand chemicals. Obviously, this can feel overwhelming. Where to start?

Every single chemical on the SIN List fulfils the criteria for being a Substance of Very High Concern (SVHC) stipulated in the EU’s REACH legislation. This means that each of them should be of the highest priority for phasing out.

Nevertheless, one needs to start somewhere. ChemSec advocates starting with hazardous chemicals that are either used in large amounts, or those that are easiest to substitute. This is where the filters come in.


Use the database functions

One organisation may be interested mainly in PFAS chemicals or endocrine disruptors. Others may want to keep track of the chemicals under scrutiny by ECHA. This is why we provide the different filter options. By combining several filter options it is possible to customise an individual high-priority list.


SIN Groups

Approaching chemicals management chemical by chemical is not very efficient. More and more companies and regulatory agencies are looking at groups of chemicals instead. The chemicals within a group have similar chemical structures and hence they often have similar hazardous properties.

The chemicals on the SIN List have been divided into 15 groups, of which several are further divided into subgroups. When addressing one chemical, be sure to avoid replacing it with others from the same group.


Health and environmental concerns

Chemicals can be problematic for several different reasons and perhaps you would like to focus your efforts on some specific aspect, for example endocrine-disrupting chemicals. There might be situations where concerns for the environment have priority over concerns for human health, or the other way around.



In a certain business sector, certain chemicals may be more relevant. When you filter the results by specifying the business sector you are interested in, the SIN List displays the chemicals relevant to this industry. Naturally, we cannot guarantee that you will, or will not, find a specific chemical in your sector.



Knowing the function of a chemical is often a key to substitution. Chemicals are not just randomly added to a product, they are there to serve a specific purpose. Knowing the function of a chemical can help understand what kind of products one might expect to find it in and what type of requirements an alternative needs to fulfil.


REACH status

The SIN List is still far ahead of the REACH process, but about one-third of the SIN Listed chemicals appear in some REACH process such as CoRAP (substance evaluation), or restricted to specific uses, they may already be on the Candidate List or even subject to authorisation.

Filtering chemicals by their REACH status shows you which stage they are currently at in the regulatory context: Registration, CoRAP, Candidate List or Authorisation List.

Chemicals that are produced in or imported into the EU in an amount over one ton need to be registered with the ECHA. You can choose to have a look at these chemicals only, which constitute about half of the chemicals on the SIN List. Non-registered chemicals or chemicals that are used only in closed processes (intermediates) can still be relevant to keep track of as they may enter the EU via imported products or be produced in low volumes.

If a substance is on CoRAP it indicates that authorities are evaluating the hazard properties of this substance due to a specific concern.

When a substance is added to the Candidate List consumers have the right to know if its concentration exceeds 0.1%, according to article 33 in REACH. The Candidate List is also the first step towards the Authorisation List. If a substance is on REACH annex XIV, the Authorisation List, it is not allowed to be used without authorisation to do so.

The SIN List is regularly updated to include regulatory changes.

Basic chemical information about chemicals on the SIN List has been collected from two main sources: The European Chemicals Agency (ECHA) (information about use, classification and registration) and the US EPA Chemical Data Reporting database (registration).
