Coloured Cups – are they safe?
Mooncup (UK) recently blogged about why their cup will never be coloured.
“Call us boring(!), but we’re not willing to compromise our ethical status for a non-essential additive with a dubious health and ethical history.”
Which sparked some discussion on the topic here: http://menstrual-cups.livejournal.com/2742047.html, given that part of their reasoning included the use of non-vegan things as food colours (despite the fact cups aren’t consumed and some of their examples aren’t actually used as food colours anyway)
JuJu has the following in their FAQ:
“Does JuJu come in any other colour?
At this point in time, JuJu is only available in a clear/semi-opaque colour. Until such time as we are able to gain an accurate understanding of the effects of the addition of dyes on our bodies, we have chosen to manufacture JuJu without any colour additives.”
But it is an interesting topic.. I have e-mailed the cup companies (Iriscup, CupLee, Ladycup Lunette, MeLuna, Miacup, and Shecup) to ask them about the colours and see what they have to say on the matter, and I’ll update this post when I’ve heard back from any In the meantime, feel free to discuss!
– edit —
I’ve heard back from a couple of the cup companies.
They of course said the colours are safe but sent me several pdf files of their test results, which shows the testing of both the colours (first file) and the general cup material. Interestingly, I believe it’s saying that the plastic the cups are made from was tested on animals (presumably as part of checking the plastic is safe for use with people), as is referenced in the last file. I’d never thought about that being a component of testing, and I wonder if the other cups have been likewise tested.
Meluna_Masterbatches_Safety sheet – Info on the colours – they are food safe (though that doesn’t mean they are “food colours” like you’d use to make a cake blue)
THERMOLAST_M_englisch – Information on the plastic material the cups are made from (from the manufacturer I presume)
TM4MED_ISO10993-5 -Seems to be a certificate of a testing where the material was left in contact with the equivalent of human tissue and checked to see if it was reactive (it shows no reaction, whereas latex showed reactions).
TM4MED_USP661 – Information on a few tests that were run (I admit, I don’t really understand most of it heh)
TM4MED_USPVI – Test result certificate
Said they would get back to me in a few days
Said they will issue a public statement on it, and that they would contact me again in a few days – which they did, saying they have forwarded my e-mail to their head office. They say they realise it’s an important issue, so they are gathering information from their experts and will get back to me.
Secret Cup company (who are bringing out the new cup)
Said that as far as they know, the colours they are polling people on (see this post) plus clear and grey are the only colours that are already tested and approved by FDA… and that other colours (like purples and whatnot) would need to go through the process of testing and approval.
