best temperatures

Most of our products contain spores of indigenous bacilli microbes

What are the best temperatures to keep them happy? 

Adding synthetic enzymes to soap is so yesterday. Enzymes are harsh chemicals and can cause all sorts of allergic reactions. Mrs Martin’s products do not use enzymes, or any harsh chemicals. Instead, our products include intelligent microbes that make microscopic amounts of the correct enzymes on demand. Our friendly microbes help with cleaning, and with rehabilitating the waste water. This technology is the result of 20 years’ research by the CSIR, initially to address problems caused by superbugs.

We recently sat down with our chief scientist to chat about temperatures. He explained that due to proprietary technology our spores are tolerant of temperatures up to 90°C. If you wash your linen at temperatures higher than 90°C, the spores will die. If you pour the detergent into boiling water, the spores will die.

The spores can hatch at a range of temperatures but the optimum growth temperature is 35°C. That also means that people who prefer to clean with lukewarm water, can do so.

Once the spores have hatched, the microbes can tolerate temperatures up to 60°C. 

Microbes are actually not too delicate

Microbes are masters of adapting to their environment – that is why they are the largest population of living creatures on earth! Also keep in mind that each millilitre of soap holds more than 10 million spores so as long as boiling water is not used, there will be plenty hatching at any stage of the cleaning process.

So feel free to wash your towels on the hottest cycle. While any microbes that hatched before the water got really hot, will die, millions of spores will survive and hatch afterwards. They will be working in your washing machine drum and pipes and in your towels until it is completely dry.

In summary:

  • Spores are tolerant up to 90°C. At boiling point, they die.
  • Optimum growth temperature is 35°C.
  • Once hatched, the microbes can tolerate up to 60°C.
