The planet is our home; we need to be more responsible. Here's what I do.

Chip fat+ Drain cleaner = Soap

We recently decided another good use of our own produce would be to use honey and beeswax that we collect to make soap.

We have made soap before but it’s been a while.

This was actually pretty easy. All we needed basically was drain cleaner and chip fat.


The internet was really helpful. We used a site (in Dutch) called ‘know everything about soap’ to check the quantities of each. We combined 500g chip fat, 450g coconut oil and 150g of our own beeswax. With these quantities we needed 151g of sodium hydroxide (drain cleaner) and 408g water to create the mix.

The drain cleaner when mixed with water creates heat. The fat needs to be heated and when the two are at the same correct temperature they need to be combined.

After much stirring the consistency of the mix changes from a thick liquid to a solidifying mix. This is the process of saponification. After that the combined ingredients need to be poured into a flexible container and left to cool.

As it sets we found that it changed colour quite dramatically, starting off rich honey colour but ending up an innoffensive creamy hue.

After 36 hours we can cut it into blocks with an improvised cheese type cutter. Then we wait four weeks and it’ll be useable.

We plan to wrap it and sell some and keep some for ourselves. I suspect we’ll make some more in a day or two.

    What kind of oil is the chip fat and, more importantly, is it used? I’m trying to imagine what it smells like.

      Irs new cooking fat. We used a vegetable base fat that’s in solid blocks. Thw saponification makes it smell of soap.
