Bad? Really?

Is this stuff really bad?

Well, the users that added it think it is.

That doesn't mean it is. Often, these things are subjective.

If an ingredient occurs in a product type that you use, you should have a look and see why it is considered bad.
That's what the evidence is for - for you to read the reasons and make up your own mind.

We are constantly exposed to people telling us what is right and wrong and don't always check what they are saying - the whole point of badlist and goodlist is that you find out for yourself. All the evidence here should be reliable (evidence deemed unreliable may be removed - eventually there will be a voting system in place to do this!)

Hopefully you will learn something useful from this site, even if you disagree with what is 'bad'.

Hey! I Added Something... Its Gone?!

Eep! Sorry :-/
There are a few reasons why this might have happened...


The first reason is that it may have been deemed unsuitable (this happens sometimes with ingredients especially ) - check What can I add? to be sure of what ingredients to list.

If you did that, and it still went then maybe its a duplicate? If you added an ingredient that is already here, but is known as something different in a different country, or has more than one commercial name (in the case of pesticides for example), or different spellings, then re-list it but select the one that is already listed in the 'also known as' box - you won't have to re-add all the information about it then.

Still gone? Probably there was no evidence attached to it... we need evidence for this to be reliable!


Your generic got removed? Probably it was just re-named for standardisation purposes.


Products will get removed if they are not listed to exclude anything, or responsibly source anything. We don't want to give free advertising to irresponsible products.


If some evidence you added got removed, the moderators deemed it to be unreliable. Try finding evidence from a reliable source.

In future, this will be done by voting - you and other users can vote up and vote down evidence. Only the best evidence will be shown.

What Are Reliable Sources?

Generally : peer reviewed material, or unbiased news sources.
Charitable organisations' publications tend to be reliable.
United Nations reports.
Government reports (tend to be based on scientific articles - go back to source if possible)

Academic search:

Some academic journal websites:

Some academic research review sites:

What Evidence Can I Add?

We want all the evidence linked from the site to be reliable. The whole point of this website is that the information here is backed with scientific evidence, to provide credible reasons why certain ingredients really are bad.

Sadly this means it cannot just be something you read on the Internet.

Ideally, you should add only peer reviewed material. That means academic articles, papers, journal items. These can be directly sourced from journal web sites, or you can use Google Scholar to look things up.
Note; you may not be able to view an entire article unless you are on an academic campus (but its worth reading the abstract anyway!).

You can also use reliable sources like BBC News, The New Scientist, Scientific American, for example.

See more sources at What are reliable sources?

What Can I Add?

Please add only named ingredients.
These are things that you could find on an ingredient list, or in the case of "thing" products (like plastic bottles), use the chemical names if you can (like Polyethlyene terephthalate).
If you can be as specific as possible then this will help others find out about what is in their products, and better work out what they consider to be bad.

Please do not include groups of ingredients (like "Pesticides", "Petrochemicals", "Non-biodegradables", "Unsustainables"). List the specific examples of these things and tag them!

Please do not include by-products of ingredients - if something breaks down into something else that is harmful - list the original ingredient. E.g. Chlorinated Bleach breaks down into Dioxin, but Dioxin is not an ingredient - it is the bleach that is the source.

Remember: the information provided here is intended to allow other people to make up their own minds - adding an ingredient that is ambiguous or includes a wide range of more specific ingredients will make readers less certain of the facts - by being ambiguous or inflammatory, the quality of information held here is diluted.

Also Known As...

You have an ingredient that is known by many names...
Best thing to do is to see if you can find it on the site, using the search (or maybe look for some generic product it is commonly found in) and then add the version you know of (be it differently spelled, or a different commercial name) and use the 'also known as' drop down box to select the one we have listed.

This way, you don't have to duplicate information, the whole process a lot easier!

If you are unsure about whether it is the same, you could add it anyway, and mention that in the wiki ('why is it bad') entry.

What Is A 'Generic'?

A 'Generic' or 'Generic Product' is a product that is not specific to any manufacturer, and may be made in different ways, but is essentially the same thing.

An example:

Peanut Butter is a Generic because it can be made by many companies - if you want to buy peanut butter, you are probably happy to buy many brands of peanut butter.

Generics differ from Products (on the site) in that Products are branded - they are specific brands of a Generic.

What Am I Voting For?

The voting system is to filter our spam or incorrect entries.

Basically when you vote on an ingredient you are voting for its "badness".

In this case up means "Yes, I agree that this ingredient is bad" (i.e. increasing support for its "badness"). Therefore down means "I disagree, this is not bad".

With regards to voting on evidence: up means "This evidence is reliable", so down means "This evidence is unreliable".

In both cases, clear means "Retract my vote - I am impartial".

What Is Flagging For?

If you think a listing is inappropriate you can flag it to alert a moderator.

Inappropriate material may contain:

- Bogus information
- Profanity
- Slander
- Propaganda

Or, you may be the creator but unsure if it belongs here... flag it and we'll have a look.

How Are Products Rated?

A simple percentage:

How many things doest the product exclude (or responsibly source) out of the things know to exist in its generic (parent) type of product.

Why Not List Products That Do Contain Bad Stuff?

Attacks could be made on brands with false information, and we don't want that.

We would rather promote the good things - the more links to them on the internet, the higher their rank in search engines and the better they should do, in theory.

So, if you spot something bad in a branded product - don't despair, list the generic product type (if it isn't already) then find a branded product that doesn't contain the bad thing, and list that!
