How to make tomato basil soap

Tomatoes are rich in vitamins and minerals, and contain a variety of beneficial nutrients and antioxidants like lycopene, choline, and beta-carotene.  Many of these antioxidants have been found to prevent some types of cancer. So why not turn this superfood into super soap?!

There are several ways to make tomato soap but I prefer substituting water with fresh tomato juice. Earthy fragrances or essential oils would be a great complement to this soap. Use your favorite recipe or try the one below.


  • 2  – 3 large, ripe tomatoes (the amount of juice will vary depending on size but one large tomato typically yields about 4 ounces)
  • Juicer
  • 1 Tablespoon dried basil (or more if you desire)


Sometimes liquids with sugar, like milk, can start to form little clumps as the lye heats it up .To avoid this, juice the tomato and freeze it first. Then when you’re ready to make soap, slowly add the lye to the frozen juice and stir until dissolved.

Makes 36.4 ounces (a little over 2 lbs.)

8.4 oz. Fresh tomato juice
3.3 oz. Sodium hydroxide
1.5 oz. Fragrance
1.2 oz. Castor oil
5.5 oz. Coconut oil
14.8 oz. Olive oil
2.4 oz. Shea butter

  1. Wash and rinse the tomatoes.
  2. Juice the tomatoes.
  3. Measure out the juice and set aside. If you have some left over, simply freeze it to use another time.
  4. Measure and pour the lye, then slowly stir until dissolved. To prevent the sugars from heating up and clumping, place the lye container in an ice bath.
  5. When the lye mixture has cooled, added it to the oils and blend until medium trace.
  6. Stir in the fragrance and dried basil.
  7. Slowly pour soup into the mold and give it a few bangs on the counter to release any air pockets.

This recipe is heavy on the olive oil so allow 48 – 72 hours before unmolding. Allow at least 6 weeks to cure (longer is better with olive oil soaps).

There you have it! Beautiful fresh tomato basil soap!
