Manuka honey has been on an upward trend the past few years and not without reason. The medicinal properties of honey have been recorded since ancient times, and manuka honey has one of the highest anti-microbial activity, inhibiting growth of over 60 species of bacteria (Mandal & Mandal, 2011). It is used to assist in wound healing, in skin care, prevent and heal infections and stimulate growth of new skin cells. The importance of natural remedies, such as honey, has increased in importance “as resistant pathogens develop and spread, the effectiveness of the antibiotics is diminished”. The quoted paper ‘Honey: its medicinal property and antibacterial activity‘ is a good read and accessible to the public.

Honey soaps, especially soaps containing Manuka honey and essential oil, are particular effective cleansers in that they contain anti-microbial properties yet remain mild and gentle on the skin. However, honey soaps are tricky to make, because the additional sugar can cause the soap to overheat and burn. The higher temperature are difficult to work with, but if you follow a few tricks it is possible to create a beautiful bar of soap with all the benefits that honey will add to it.

TOP SOAPING TIPS WITH HONEY:

 

  1. soap at cool temperatures
  2. do not insulate your soap
  3. do not discount your water
  4. place the soap in the fridge for the first 2 hours after pouring

The Manuka soap that we are making uses Manuka honey, Manuka essential oils and beeswax from Manuka honey, to maximise the benefits of Manuka in the soap. I used the Manuka essential oil from Pure Nature, but alternatively you can use a tea tree oil for a cheaper alternative. The Manuka honey I bought from my local supermarket, and I didn’t go for the most expensive one! The Manuka beeswax I still had left over from a friend, and you can use any beeswax as a substitute, although I would recommend to go for an unbleached and undeodorised beeswax.

Before starting, please read the safety and precautions post, especially since this tutorial requires the handling of caustic soda!

If you have never made cold-process soap before, I strongly recommend you check out the basic cold process soap tutorial first.

ONE: Prepare your lye as usual and leave to cool down to room temperature.

TWO: Weigh out the coconut oil and beeswax, and heat in the microwave or stove top until the oil and wax have melted.

THREE: Add the olive oil, sunflower oil and castor oil to the now liquid coconut oil and beeswax, and give it a quick stir.

FOUR: MAKE SURE YOUR LYE HAS COOLED DOWN TO ROOM TEMPERATURE OR LOWER. Add two tablespoons of Manuka honey to the lye and stir, stir, stir until the honey has completely dissolved. This will take a while, but don’t be tempted to use warm lye because the honey will heat up the lye and you can end up burning the lye if the lye is still warm. Just be patient and keep stirring. You’ll notice the lye turning a reddish colour. That’s fine and how it should be. Let it cool down again.

FIVE: Check the temperature of your oils. They should be no warmer than 32 degrees Celsius (90 degrees Fahrenheit). Add the Manuka essential oil to the oils and give the oils a good stir.

SIX: Add the lye to the oils, and use your whisk or stick blender to mix the lye/oil blend until it has emulsified to a medium trace. Pour the soap into the mould.

For the swirly surface, I used a chopstick in a looping figure 8 pattern along the length of the soap.

SEVEN: PLACE THE SOAP IN THE FRIDGE FOR THE FIRST TWO HOURS! This is important. The sugars will heat up the soap during the chemical reaction, and placing it in a cold environment will both prevent the soap from heating up too much and will help keep the colour of the soap a nice cream colour rather than the usual caramel-brown colour of honey soaps.

After two hours (approximately), take the soap out and place it somewhere cool to cure. I put mine in the laundry, which is the coolest room in our house. Don’t insulate or cover your soap!

EIGHT: Let the soap cure for a couple of days before unmoulding, and then let it harden for another few days before cutting it into bars. The bars of soap will need a further 6-8 weeks to cure before they are ready for use.

Note: honey is a humectant, meaning it will draw moisture to the product and honey soaps are prone to DOS (dreaded orange spot), which are harmless but don’t look pretty. Make sure to store the soaps in a dry area to prevent DOS and moisture forming on the soap.

  • 30 ml Manuka essential oil

Directions

  1. Measure out the caustic soda and the water. Then add the caustic soda to the water  (not the other way round!) and stir until the caustic soda has completely dissolved. Set aside to cool down.
  2. Weigh out the coconut oil and beeswax and heat in the microwave or on the stove top until completely melted.
  3. Add the olive oil, sunflower oil and castor oil and give it a quick stir.
  4. Once the lye has cooled down to room temperature, add 2 tablespoons of Manuka honey and stir until dissolved.
  5. Check the temperature of the oils. They should be no warmer than 32 C (90 F).
  6. Add the Manuka essential oil to the oils and give everything a good stir.
  7. Carefully pour the lye to the oils and, using a stick blender, mix until emulsified to a medium trace.
  8. Pour the soap into the soap mould and place it in the fridge for 2 hours.
  9. Remove from fridge, and place it in a cool spot to cure.
  10. Leave the soap to cure a couple of days before unmoulding, and then let it stand for another few days before cutting into bars. The soap bars will need to cure for a further 6-8 weeks until ready for use.
