Varies factors can ultimately determine the lather that a soap is able to produce. One of these factors involves which oils or fats were used to make the soap. The more saturated the fat, the less soluble the soap will be in water, therefore it will produce a weak lather. However, though it may be weak, it is longer lasting. Coconut oil has a high quantity of lauric acid, which offers a strong lather that can even work when using seawater.
