Briochin is a French household ‘natural’ products brand – they make all manner of cleaning products with a retro, olde-worlde look and feel.
The packaging is generally retro, usually navy-blue cardboard with white lettering and most of the products are certified by Ecocert as not harmful to the environment. I value them too for their pleasant, natural smells, often based on lavender.
Among the Briochin products I have permanently in the house are liquid black soap (savon noir liquide); cleaning vinegar at 14% solution; bicarb and lavender oil, but they also make wash powders and liquid clothing wash; hand wash, surface cleaners, etc. The range, originally confined to one or two products, is being expanded all the time.
You can buy Briochin products from supermarkets and DIY stores, and the company’s website.
