Butter London

I’ve been informed Butter London are now adding silk to their polishes, so they are no longer vegan! Not sure if it’s all polishes.

Just talked to Nonie-
We are completely free of animal byproducts. Including guanine and
synthetically-derived guanine.

Hope that helps!

I’ve recently learned that there is in fact synthetically-derived guanine that is sometimes used in nail polish. Is that the case with yours?? That would explain everything… Please let me know!

Oh hi, I had just sent you another email actually. Thanks for the info. I don’t understand why you have “vegan” on your website, since guanine is an animal product, usually derived from fish scales. Could you please explain this?

Could you please also cancel my order and refund my money; I’m vegan and don’t use products containing guanine.

Hi Joanne,

Good day! I just got a response back from butter London.

They advised that almost all lacquers “may contain” guanine. I can
send you an ingredient sheet if you would like.

Please let me know if you have any other questions.

Yes, could you please tell me which shades do contain guanine?

Thank you,

Good day Joanne,

Thank you for the inquiry.

Please note that Guanine is an ingredient that is listed in the ‘May
Contain’ list of ingredients for the butter LONDON lacquers.

Let us know how we can best support you.

Hello Gautham,

Thanks very much for the reply! I do have another question actually – on a
beauty store website that sells some Butter London, I saw ingredients lists
for some of the polishes that did have guanine in the “may contain” list at
the end. I realize that these third party sites may have inaccurate or out
of date ingredients lists, but just wanted to double check with you whether
any of your polishes do/did contain guanine, and if so which ones?

Thanks very much!

Dear Joanne,

Good day!

The response from the lacquer’s creator was “Lady Muck is infused with
synthetic pearl pigment to give the lacquer its shimmer and does not
contain pearl and/ or guanine”.

Hope this helps. Please let me know if you have any other questions.

  1. This is very helpful. Thanks for investigating!

    So IS it vegan????

  3. I have contacted Leaping Bunny two weeks ago and they verified that Butter London is not registered in their “Compassionate Shopping Guide”, and they are using their Leaping Bunny logo without paying for licensing fees (as required by Leaping Bunny)

    I also contacted BL and they said their products were not tested on animals, but after learning from Leaping Bunny about BL using their logo without permission is discourging to me as a consumer to be able to feel confident of using their products.

  4. Hey! My name is Anna and I own a vegan cruelty free nail polish brand in Australia. After reading your blog post I wanted to explain how the labelling on nail polish works. All the ingredients used in every nail polish across the board are listed first. The ‘may contain’ ingredients are all of the ingredients that are used to create the different colours. They do it this way so they can print the same sticker for every bottle. So to me, I read this as some of Butter London’s nail colours actually DO contain guanine.

    Also the leaping bunny is a really hard logo to obtain and yes, you do need to pay a licensing fee to use it, depending on how high your turnover is. The higher your turnover, the more you pay. It’s really difficult to become cruelty free accredited. Not only do you have to not test the final product on animals, neither can anyone within your supply chain. It sounds like Butter London would be using a single ingredient which has been, which is why they can’t get accredited by leaping bunny.

    I hope that helps!
