I recently ran a liquid soap training as a promotion for a friend who recently opened up his own soap supply store (more on this later). After borrowing a few materials (three buckets and a spatula), all that was left was to buy a little salt, a chemical called Tansigex and add some water.
The process is dead simple: 7.5L of water in bucket 1, 7.5L of water plus with 1kg of dissolved salt in bucket 2, and 1kg of the mysterious Tansigex in bucket 3. I’d love to tell you what Tansigex is exactly, but Google searches only brought up references to other Peace Corps Burkina Faso blogs (obviously we’re in a self-reference loop here). Then just whip the Tansigex and alternate adding a cup of salt and fresh water while continuing to stir. Let it sit overnight and the melange will result in ~13L of soap. If you choose, add colorant (we chose green) and a cap or two of perfume to make it smell nice.
Total material costs, including bottles, was 2,650 CFA (~$5.90). Since this was a promotion, we gave the soap made during the training to the ladies for free. When they sell the soap, total revenues will be between 4,000-5,000 CFA (~$8.90-11.10) depending on the mix of large and small bottles (small 0.5L bottles sell for 200 CFA and large 1.5L bottles for 500 CFA (~$0.45-1.10). Not a bad margin, and a great way to help prevent disease. Wash those hands people!
