The three main processes involved in the scouring are saponification, emulsification and detergency.
At this time, it is safe to use the soap, since saponification is in essence complete.
The saponification value for a specific fat will vary by season and by specimen species.
Saponification in oil paintings was first described in 1997.
The saponification value must be converted into an equivalent sodium hydroxide value for use in cold process soapmaking.
Saponification charts should also be used in hot processes, but are not necessary for the fully boiled hot-process soaping.
Saponification of the ester completes the preparation of zenarestat.
A cold-process soapmaker first looks up the saponification value for each unique fat on an oil specification sheet.
