YOU DO NOT NEED MUCH TO MAKE LAUNDRY BAR SOAP

I made this with just: 1. Oil: that provided the fatty acid: you can use either Palm Kernel Oil or bleached Palm Oil. It is adviceable to blend the oils so the soap will foam well and last. Use 70 percent bleached Palm Oil and 20percent good quality Palm Kernel Oil. (I will teach you later how to test for good quality Palm Kernel Oil). Use 1:4 ratio of caustic soda to oil. 2. Caustic soda: source of alkali. Use 1:2 caustic soda to water ratio and dissolve the caustic soda. Soak for two days. 3. Soda ash: to increase the size. Your soap can contain between 30 to 40 percent soda ash by volume of oil. 4. Liquid detergent: this is to prevent your soap mixture from separating. I reduces the surface tension and helps your mixture to be homogenous. Check my other write up on how to make a good liquid detergent. 5. Colour and perfume are optional. You don't need silicate and calcium carbonate as your soap will already be very hard. I didn't add any colour. For laundry soap, the question is does it foam? Does it last? Hope it doesn't itch? Is the texture marketable? Is it big with profit? Keep your chemical inventory low. Optimize size, quality, and profit.
