my liquid soap experiment


last year, I read an awful lot about making liquid soap using the glycerine method.  I'd never made liquid soap before, mainly because it seems such a faff!  But this method sounded quick & fun, perfect for a busy girl like me, and I wanted to have a go.  I ordered some KOH and when it arrived, this is what happened:

weighed out the KOH

oils (olive & a bit of castor) in the crock pot

 adding the KOH to the HOT glycerine, on a small flame

This part was interesting (read: scary!) the KOH fizzes as you add it to the glycerine, so you have to add slowly and stir it down as you do so. which was fun one handed whilst holding the camera steady with the other hand!  Too much and it will volcano out of the pan!  Keep stirring until it is fully disolved.

fizz fizz whoosh!

add the lye slowly to the oils and stir with a whisk

it changes fast, from clear to golden to.......

dark rich copper with sticky toffee forming in the middle

it thickens very quickly and goes from caramel to this:

lovely thick custard.

Now it is time to stop stirring. I left it over night and the next day the consistency was very unexpected. I thought I'd get sticky taffy, but instead, it was rock solid like toffee.




I could not get any out of the pot, so I reaheated it, weighed some out and plopped into a jam jar.It was like very sticky runny honey at this stage when hot.  I added freshly boiled water to dilute, it is impossible to stir it in, you just have to leave it to dissolve for a few hours, then stir it gently to avoid bubbles!

undiluted in the jar

with the hot water added. you can see the water floating on the surface.

Hope you enjoyed reading about my liquid soap experiment part 2 will follow soon. I'll show you how it turned out, what happened when I added EO and how it feels on the skin 8 months later. see you soon x

  8. This is how I make my LQ and shampoo. I have to say it does not go solid though. I wonder if that is to do with the oils used?

    Great post!
