Canola oil is a good moisturizer but is less saturated than other fats, so it can be slow to saponify. Use it in place of more expensive oils like olive. Needs to be mixed with other saturated fats in order to speed up saponification. Use as a base oil up to 50%.
Saponification is the process of making soap molecules from the chemical reaction in which fatty esters (fats and oils) are hydrolysed in basic conditions. This process converts fats and oils, via a basic reaction medium, to salts of these fatty acids. General Form

13/4/2020 · The first detergent (or surface-active agent) was soap. In a strictly chemical sense, any compound formed by the reaction of a water-insoluble fatty acid with an organic base or an alkali metal may be called a soap. Practically, however, the soap industry is concerned mainly with those water-soluble soaps that result from the interaction between fatty acids and alkali metals.
Hydrolysis using dilute alkali This is the usual way of hydrolysing esters. The ester is heated under reflux with a dilute alkali like sodium hydroxide solution. There are two big advantages of doing this rather than using a dilute acid. The reactions are one-way rather
