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.

Location Policy for Stockists

SESI seeks to maintain an optimal distance between stockists. We aim that traders aren’t so far apart that consumers don't have a nearby refill station, but not too close that they could undermine one another's businesses. These are the factors:

  • Are you located in a village, town or the centre or outskirts of a city
  • Distance between residents and their shopping areas (this has a direct link to what means of transport people are likely to use)
  • Demographics
  • CO2…. If people end up burning fossil fuels (by driving long distances) in order to reduce plastic pollution, we wish to be part of an ongoing solution to that.

In busy urban areas, we will supply to traders more distant than 15 minutes walking from each other.  For small towns and villages (< 10,000 population approximately) it would be unusual to support two refill stations in the same settlement. 

So far this is working well and so far all our traders have upped their refilling activity even when other refill stations open in the area.

Please let us know if instead of supporting the network, a trader is jeopardising decent trading standards and the spirit of solidarity.

Where are SESI products made?

SESI detergents are made 50 miles near to Oxford by a long going, family run business with sound work ethics. Our formulas are mild, harmless, vegan and cruelty free. 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. We opt out from exotic essential oils which would need to be imported from far out, thus reducing carbon footprint where possible.

Do your products contain harmful ingredients?

Such ingredients include Parabens, Chlorine Bleaches, Optical Brightener, Thiazolinones, Sulphites, Methylisothiazolinone (CMIT), Gluten, Alcohol, SLS, ALS, ALES and Phosphates. No, SESI products do not contain any of the above ingredients. Our formulas are designed to be harmless and free of those ingredients.

Do SESI products contain enzymes?

There are vegan enzymes in our Biological Laundry Liquid; none of the other SESI products contain enzymes.

Are SESI products harmful in septic tanks?

NO. SESI Refill do not contain bleach, phosphates or nonylphenol ethoxylate, which are harmful to septic tanks and the environment.

Do SESI products contain palm oil?

palm oil content in sesi products


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.


Sodium Laureth Sulfate or Sodium Lauryl Sulfate? Sodium Laureth Sulphate:

  • Is a benign and gentle surfactant not to be confused with Sodium Lauryl Sulfate
  • Is present in small quantities in SESI: Hand Soap, Washing-Up (ginger scent), Bio Laundry Liquid and the Non Bio Laundry Liquid
  • Is derived from the blend of coconut oil
