Using only the natural colours from the raw materials in this soapy spa bar has resulted in a warm, apricot coloured soap, scented with pure essential oils, and a nice, diagonal stripe of Jojoba Scrub Granules through the centre.  This is one of my favourite ways of including an exfoliant in soap; I don't always want a very scrubby bar, so it has a light intermittent exfoliating action with the strip in the centre of the bar.

There are two options for the Jojoba Scrub strip down the middle – either have a darker opaque strip, or use some clear soap – see the graphics for your choice. You only need extra clear soap in the trolley if you want a darker opaque strip. By using some of the opaque soap you'll have a creamier coloured strip.

This tutorial makes two batches of 6 soaps (so a total of 12 soaps) and you'll have some ingredients left over for another project.

What you need:

• 1kg Stephenson Crystal TBS (Triple Butter) MP Soap Base  or you can subsitute SFIC Cocoa Butter or Palm Free Mango Butter
• 200g Stephenson Crystal SLS/SLES/ Free Base or similar
• 25ml Heavenly Essential Oil Blend
• 1 teaspoon Caramel Mediterranean Clay
• 5g (1 rounded teaspoon) Jojoba Scrub Granules
• 5 - 10ml Sodium Lactate Plus
• Budget Wise Flex Mould –  Square (Large Guest)

Equipment:

• 2 x 750ml microwave safe jugs
• Spatulas, spoons or stirring sticks
• Digital Scales - helpful but optional
• Spare tray or baking tray to place the moulds on
• Thermometer – helpful, though optional
• Pipette or dropper for essential oil or fragrance
• Isopropyl Alcohol & Spritz Bottle
• Clean Up Tool (or similar)
  
  

Method: 

• Measure Sodium Lactate into the small beaker or glass and add the Caramel clay to this, stir to remove any dry spots 
• Dice the TBS Soap Base into cubes and place half (500g) into the Pyrex Jug and place in the microwave 
• Heat in short bursts until the soap is liquid. Take care not to overheat the soap – 
• Once Liquid remove from the microwave and add sufficient clay to the soap until you reach a colour you are happy with
• Now add 20g/ml Heavly Essential Oil Blend and stir well
• Pour into the soap mould, spritz the surface with Isopropyl Alcohol to remove surface bubbles and allow to set.

• Once this has set fully, mark one corner of the mould (so you keep it at the front left) and remove the soaps, one by one,
• and then slice a piece diagonally from the centre about 2 - 4mm wide.
• Then carefully replace the two halves into the cavity they came froom and continue to divide the rest of the bars
• and replace back into the mould

• Use a chopstick or spatula to keep the halves to the edges of the mould cavities.
• These are now ready for the jojoba scrub stripe 

• There are two ways to make the centre stripe - very dark (using clear base) or pastel (using TBS base)
• Dice approximately 200g of your chosen soap base and melt in the microwave
• Once melted remove from microwave and add the some of the pre-hydrated clay mixture if you are using
• Add 1 rounded teaspoon Jojoba Scrub Granules and mix well
• Spray the "gap" of each soap with alcohol to ensure the soap stays stuck when unmoulded
• Carefully pour each of the cavities and then allow to set up 

• You can see the soaps in the three left hand cavities have three different colour tones of scrub - the three on the right have no opaque soap base
• I used some of the offcuts to make the left hand side lines a lighter colour shade
• Once completely set up remove from the mould and clean up any over pour or soap that has seeped under the bars
• Now wrap as usual

Note:  Items in the trolley include TBS Base. Also SLS/SLES Free Clear Soap and Sodium Lactate are included, just delete these if not required.  The Clean up Tool is not included in trolley items.
