It’s easy to assume that any brand proclaiming its ‘natural’ qualities will be free from methylisothiazolinone (MI) and related preservatives, but that may not be the case.
Canadian household cleaning brand Nellie’s All-Natural arguably goes further with that ‘All’ – so I looked into the brand. Finding their ingredients wasn’t easy. Their website does give ‘free from’ attributes to their products – of ingredients such as SLS, SLES, phosphates, and many others listed here, which is great – but the ingredients don’t seem to be provided.
I made enquiries about their MI status, and was told that their four One Soap products (melon, water lily, peppermint, fragrance free) for dishwashing contain 0.1% Neolone (which is an MI-containing preservative mixture).
I eventually found the full ingredients to one of the One Soaps on the well.ca website. The product contains coconut-based cleaning agents, ethanol, water, natural fragrance – and ‘biodegradable preservative’ – which I take to be the Neolone (MI is apparently biodegradable).
“As the quantity (0.1%) is so minimal, it [Neolone] does not contribute to the listed ingredients,” I was told by a Batten Industries Inc. Customer Services Advisor.
The good news is that Nellie’s All-Natural laundry powder products are free from MI and related preservatives, and are available in the US via Amazon, but why can’t the MI be declared on their One Soaps – and indeed more widely at online points of sale?
