New cold process soap experiment

So, I had a day off and decided that I'd make a new cold process soap - I'm still experimenting to get a perfect recipe but used one I'd already tried out because I wanted to practise with some additions too.

I was sent some tussah silk and some titanium dioxide along with a gold mica, by a fabulous soaper friend of mine.  Silk adds a huge luxury factor and makes the soap feels so smooth and luxurious (check out some of the really high level brands of cosmetics, they often have some form of silk in them).  Titanium dioxide is a natural white powdered pigment that helps you achieve a white white white soap - it can create more heat though so it can be tricky to work with.  Finally the gold mica ... ahhhh, what can I say? I must have been a magpie in an earlier life because I do love the glistening shiny things!

I choose a recipe with Cocoa Butter and Apricot Kernel Oil - both fabulous for your skin and both light coloured oils to help keep the colour of the final base oil whiter too. 

I decided to use a Vanilla fragrance oil - vanilla based oils can be problematic as they often make the soap turn brown but I used a specifically designed non-discolouring version so my soap will stay as white as it is supposed to be.

Not the best picture in the world, I will admit that but you can see how creamy the colour on top is... why is this, I hear you say, when you wanted white soap? Well, here's the thing.... the gold mica was calling me and I thought why not do a lovely sprinkle on top of the final soap.  Great idea! Yes, good idea when it sprinkles but not when it clumps! So I decided to swirl it and colour the very very top layer of the soap - it created this delicious creamy looking top, I love it.  I'm hoping some of the glisten may show but I'm doubting it.  You can see from the blob on the bottom edge of the mould how white that base soap is.  Now, one of the problems with using Titanium Dioxide (or TD) is that it can produce a crackle effect - this can be due to overheating issues and TD can be the cause of that at times.  We'll see when it's cut!

Now, here's a problem ... a tiny crack.  I am showing a close up on this but it's not huge, if you were to cut the soap, it'd be the width of one bar.  The crack can be possibly caused by a little bit of overheating - the soap was kept in the fridge for a few hours to help keep the temperature down.  As I said, the TD may produce a crackle effect and the heat produced could mean that I won't have the perfect white soap either. 

Tune in for cut pics in the next few days.  I will say, it smells damn fine!!!


  1. My cracked soap has always been a temperature issue too. LOVE your textured peaks on top.

  2. It looks lovely Celine. I've had some success at mending cracks by sprinkling a little bit of water onto it while the soap is still soft - it's worth a try.

  3. That looks beautiful! Don't worry about the cracks...! they never matter once cut into chunks. Well I don't think so anyway. Soap is soap, cracks and all!

  4. Thanks Anne-Marie, I think it was either temp or the fragrance oil... either way, it was only a tiny crack and not a chasm!

    Lilli - great idea, I will remember that if it happens again.

    Tiggy - thanks for the compliment.
