Up until about 2 months ago contact tracing in Australia was very effective. Contact tracing teams were able to trace who and where each person got infected. They were also notifying/testing/isolating first and sometimes secondary downstream contacts (up to 400 people in the case of one country town outbreak).
One of the infections was traced to a department store and the interaction between the two people was caught on cctv. They walked past each other and didn't talk. It was seconds.
From the ingredients list on the Amazon product listing it contains a number of soaps derived from coconut, palm and tallow (usually beef fat). Sodium X-ate is a soap made from X.
Surprised to see this on HN, it's not my main gig but recently I've been getting into the details of exporting and selling coconut oil soap from my family's business.
It's a remarkably simple process to make soap from oil or fat. just heat and add a caustic agent. Sodium Hydroxide for bar soap or Potassium Hydroxide for liquid soap.
When I check out the competition and look at the ingredients list I'm surprised at how many different things that are in most products. Most body washes are technically detergents not soaps.
