FAQ

► Can I refill SESI detergents in any container I want?

Taking into account Health and Safety, we don’t encourage people to refill our detergents in milk or drink bottles. If customers insist in refilling SESI detergents in milk bottles, they do so at their own risk. We ask that all reusable containers are stripped off of food and/or drink labels and that you stick a SESI label on your reusable container. Your reusable bottles must be clean and dried when refilling.  Do not use drink bottles to refill SESI detergents, there is a risk that children and people who don’t read English could reach out for the bottle thinking it is a drink.

We go to great lengths to ensure our products whilst eco-friendly, are also affordable and easy to refill. We use fragrances which can be sourced locally.

►Do SESI products contain palm oil?

#PalmOil

SESI products use a coconut blend with 1% or less  of RSPO (sustainably sourced) Palm Oil (see table provided here)

We are not complacent about RSPO certified palm oil, neither do we think Coconut Oil is ‘the solution’ like the expensive eco market would have us believe. Let’s ask these questions on Coconut Oil. For now, these formulas are the most affordable to us and therefore to you who genuinely take action to reduce your plastic footprint, helping cut the staggering 12.7 million tonnes of plastic ending in our Oceans every year. SESI Refill  continues to campaign against destructive Palm and any other mono-culture endangering local and global ecosystems. In future, we wish to put energy into sourcing and using locally grown crops and we do a good deal of research on them. We believe that it should be possible for oils – whether used for fragrance, moisturisers or surfactants – to be extracted from affordable local crops, so long as these DO NOT use neonicotinoids, chemicals contributing to the extinction of bees, which in turn damage pollination and puts our land, crops and our capacity to produce food, in great danger.
