Soapmaking Steps

  1. Do research and make up your own recipe, make sure math is correct

  2. Prepare your workstation, gather all tools and ingredients AND SAFETY GEAR. Make sure you are in a safe environment before proceeding. (lye is corrosive so please make sure that no children or pets are near by)
  3. Put on your safety gear!
  4. In a well-ventilated area, measure out lye precisely with a scale (OR skip Step 4-6 if using masterbatch solution)
  5. Slowly pour lye into water. NEVER pour water onto lye as water will boil and splash explosively! Also, take care to avoid inhaling fumes.
  6. Let lye solution cool to room or desired temperature

  7. Measure out the rest of ingredients accurately with a scale
  8. Prepare those ingredients (melting & combine oils & butters etc.)
  9. Pour lye into oil(s) down shaft of blender/spatula to avoid splashing
  10. First, mix by hand and then,
  11. Use a stick blender to mix soap batter by pulsing in short intervals (take care to remove air trapped in stick blender head, also called ‘burping’ the blender) OR hand stir with whisk in intervals of few minutes of stirring and few minutes of rest 
  12. Stir until batter reaches emulsion — stick blending takes less than 5 minutes, hand-stirring takes 20 minutes to more than an hour depending on batch size
  13. Optional: add additives (fragrance, colour etc.) Take out a small portion of batter and combine additive thoroughly with no clumps and then mix into main container
  14. When batter reaches desired consistency, pour into moulds (optional: create patterns and swirls with various techniques)
  15. Cover top of the mould to keep away dust and insects, choose whether or not to insulate with towels to encourage gel phase
  16. Let set for 12-24 hours or more

  17. Un-mould hardened soap, inspect & cut! You may need to wear gloves as the soap can still be very alkaline.
  18. Place on racks to cure for 4-6 weeks in a cool dry place 

Cleaning Up

Remember to keep your protective gear on as there is still active lye in your soap batter!
