Hemp and Sea Clay Cold Process Spa Soap
This gorgeous Sea Clay soap and is featured in our new Formulating with Cosmetic Clay Book.  It is scented with the unisex scent, Lavender & Cedar, which is perfect for this type of soap.  Although this is a fairly simple Cold Process Soap, it's best to have some experience before making clay soap. 

This batch makes one full Silicone Column Mould plus two large single bars of soap, or you can use a loaf mould and you won’t need the extra mould cavities.  If you have not worked with discounted water cold process soap, take extra care when mixing the Lye and Distilled Water as the mixture will be quite concentrated.



  • Silicone Column Mould  plus spare moulds for left over soap
  • Equipment – all your usual safety and Cold Process Soap equipment including stick blender. 
  • Glass beaker or cup to hydrate the clay.


If you are a beginner, we recommend you make a few batches before attempting this soap due the clay content.   For how to make soap from Scratch, please see our Cold Process Soapmaking Instructions.  You can also watch Soap Queen's You Tube Series on Cold Process Soapmaking.

SAFETY REMINDER:  Always wear protective gloves, goggles and long sleeves.  Avoid distractions - take the phone off the hook, ensure children and pets are not in your soaping zone.  Remove any tripping hazards, clear away clutter to avoid mishaps and ensure there is good ventilation.
