How To Make Malaysia Duku Cold Process Soap.

Cold process soaps are great for the skin. As there are no artificial ingredients, the soap will nourish and keep your skin looking and feeling healthy. If you are not sure what cold process soap is; please click here. 

Today’s cold process soap recipe is for the Super Plump Duku. 

In this recipe; we combine an oil mix with lye flakes, distilled water, and mashed duku. 

The oil mix is a mixture of coconut, olive, castor and palm oil. We use 30% of each oil, and 10% for castor oil.  Each oil nourishes and makes the skin healthy and revitalised. 

For example, palm oil is rich with antioxidants which nourishes and keeps the skin looking young. 

Lye flakes are used to saponify the soap. Since this soap will have water portion and the oil portion; lye will break them up to combine them (in a process called saponification) to make them into soap. 

The mashed duku adds vitamins to revitalize and freshen the skin. The apricot fragrance oil provides a relaxing fruity smell. To add some flair, add white liquid colour pigment and sparkle gold mica to your soap. Enjoy and let us know how it went!

Visual Guide  

  1. Combine lye flakes with distilled water carefully. Wear gloves & long sleeves to avoid backsplash getting in contact with exposed skin.     
  2. Slowly mix with a whisk until all the lye flakes have dissolved in the distilled water. Solution may become hot, do be cautious. 

  3. To bring lye solution to room temperature, place container in a water bath. 

  4. Separately, pour your Oil Mix into a heat resistant mixing container. 

  5. Combine room temperature lye water with the oil mix in the same container. 

  6. Next, use a whisk and mix until it reaches thin trace. Timing of this may vary as the faster you mix, the faster solution will saponify and reaches thin trace. 

  7. Next, add in Apricot Fragrance Oil into soap mix. 

  8. Add in White Liquid Colour Pigment into the container and mix with a whisk until colour is evenly dispersed throughout the soap. 

  9. Add some Duku into the container. You may squeeze & strain the fruit before hand or you may just add them whole. 

  10. Mix everything using a whisk until colour, fruit/juice & oil are evenly dispersed throughout the soap mixture.

  11. Prepare your silicone mold. Spray with Rubbing Alcohol to sanitise mold. Next, pour in soap mixture half full into each cavity. Pour carefully, soap might still be warm.

  12. Gently tap on the mold to remove air pockets in the soap. Sprinkle in some Gold Mica and with a stick, swirl around the soap. 

  13. Next, add in more soap into the each cavity until it reaches the brim. Sprinkle on top more Gold Mica and again, swirl with a stick. Then, leave soap to harden, usually it will take 24 - 48 hours

  14. Once hardened, carefully pull mold away from soap. This will help preserve those desired sharp & crispy edges of the soap.  

  15. Whenever you feel ready, gently push soap out from the mold.  

  16. Soap will be needing 2 - 4 weeks to fully cure before it is used. Keep soap aside till then.
