Handmade soap differs from industrial soap in that, usually, an excess of fat is sometimes used to consume the alkali (super fatting), and in that the glycerin is not removed, leaving a naturally moisturizing soap and not pure detergent. The time taken for the foam to disappear in each sample is determined. If a drop applied to the middle of a soap cutting turns deep pink or fuchsia then the soap should not be used on the skin. Soaps are useful for cleaning because soap molecules have both a hydrophilic end, which dissolves in water, as well as a hydrophobic end, which is able to dissolve non polar grease molecules.

Cold-process soap making requires exact measurements of alkali and fat amounts and computing their ratio, using saponification charts to ensure that the finished product is mild and skin-friendly. Excess unreacted alkali in the soap will result in a very high pH and can burn or irritate skin. Put 16ml of water in each flask and add 8 Gms of soap. Do the same for all test tubes and with equal force. 3. The washing ability of soap depends on foaming capacity, as well as the water used in cleaning. Soap can also be made of vegetable oils, such as palm oil, and the product is typically softer. The cleansing capacity of the soaps taken is in the order: Santoor > Dove > Cinthol > Tetmosol > Lux. Looks like you’ve clipped this slide to already. 2. The presence of such salts makes the water hard and the water is called hard water. A cold-process soap maker first looks up the saponification value of the fats being used on a saponification chart, which is then used to calculate the appropriate amount of alkali. Fermentation.
