How To Create a Coathanger Swirl in Cold Process

If you have mastered cold process soap making but need to jazz it up a bit, try this technique in your next batch.

Swirling in Cold Process Soap using a Coathanger


This method of swirling was donated to us by Gabbie.  

 Yesterday l tried coathanger swirling for the first time. I've used a chopstick, a skewer and a wooden spoon to swirl my soap, but never a coathanger. l think the beauty of it is that you can get to the bottom of the soap easily while it's in the log mould, and pull it upwards & downwards; and because you're swirling 'side on' instead of the normal way, you get some really interesting patterns.  Having said that though, there are so many people who do it better than me! I was a bit chuffed though with my first attempt, it turned out much better than l had dared to hope.

 Here's the soap recipe l used:

 olive oil 275g
palm oil 250g
coconut oil 250g
rice bran oil 100g
canola oil 100g
castor oil 25g

 Purple Ultramarine 1 teaspoon (diluted in a small amount of oil or water) Titanium Dioxide 1 teaspoon (blended in a small amount of oil) 30mls Lavender Essential Oil

 Water 312mls

Sodium Hydroxide 138.5g (discounted at 7%)

 Instructions:  (basic instructions on the coathanger swirl were first found here:
 what follows is merely my interpretation.)

 l'm not usually very good at swirling because l always soap too warm, and use the stickblender for too long. This makes for a quite thick 'trace' that doesn't lend itself to swirling, but rather being 'heavily poured' into the mould, and spread around. For this recipe, l let the oils and lye go almost stone cold before making the soap. l didn't want to give it any excuse to thicken up, you want a nice runny consistency.

 Measure all your hard oils and melt them gently, then add your cold oils, and let it all cool.

 Measure your cold water, and carefully add the Sodium Hydroxide, stirring gently to

dissolve. Let this cool right down also.

 Dilute the purple colour, and set it to one side in a large pyrex jug. The Titanium Dioxide l mixed in with the warm soaping oils as they cooled.

 I'd already altered my coathanger with a pair of pliers, the straight sides are so it would fit into a smaller log mould:


 I then mixed the lye and oils with a stickblender in short bursts.

 As soon as the soap emulsified or got to that beautiful glossy 'almost trace' like stage, l put the stickblender down and didn't touch it again.

The batter was still very thin, there was a very faint pour line if you lifted the spoon above the soap & drizzled, but nothing like what l normally experience. lt was like very thin cream and su

nk back into the surface quickly.

 l added my fragrance (lavender essential oil) and stirred with a spatula.

 I then split the batch in half and coloured one half purple.

 l then started pouring the purple and white soap into the mould in alternate thin layers. l used my wooden log mould, and had it lined and ready to go.

First up was a thin layer of white soap along the bottom, about a centimetre's worth. Because the soap was still very runny, when l started the purple layer, l poured it over the back of a spatula, as if l'd poured straight into the mould l think it would have sunk completely to the bottom instead of forming 'stripes'. I continued pouring,  alternating colours and always over the back of a spatula so that the stripes stayed roughly 'on top' of each other. Keep layering the two colours until you run out of soap mix.

 Once the mould is full, insert the coathanger into the mould right to the bottom.

 (here's a pic of how it goes in, just pretend there is soap in the mould!)

 Because it was only my first time, l wasn't sure which way to swirl with the hanger, should it be from side to side, or up and down? l decided on mostly up and down, and zig zagged in a //// pattern from one long edge of the mould across to the other. l then added in ONE 'side to side' 'Z' movement just in case, and pulled the coathanger straight out. 

 Overall l didn't swirl too much at all, l'm no expert, but l figured the more l fiddled around with it, the more l would be blending the two colours, and l wanted them to be quite distinct, not a muddy third colour.

 Then l put the soap to bed as per usual, and cut it 24 hours later.
