Use Caster oil at a low percentage when making homemade soap. It should be used no more than 5 to 10% of the total weight of oils.  If it’s used at higher amounts a soft or sticky bar of soap will result.   You don’t need to use very much of this oil in order to reap its skin care benefits.

Castor oil has a shelf life of approximately two years, but is advised to use within six months.  Store it out of direct sunlight, away from moisture and heat.  Moisture causes it to become rancid, quickly, leading to spoiling.  Excessive heat can cause it to decompose.  Do not use it past expiration date and discard if it's thick or clumpy.


An immersion blender is used for making homemade soap.  It speeds up the soap making process.  CAUTION!  When using an immersion blender, with Caster, trace has a way of sneaking up on you, quickly!  If this happens, your soap may become too thick to pour into your soap molds. What should you do?

Reduce the time using the immersion blender and stir manually. Use at your discretion.  Learn how to make soap from experienced soap makers. Follow proven homemade soap recipes!
