Concerning the enrichment oil, two methods could be used:-

The first, more rapid, where a percentage of 'excess oil' is anticiapted in the formula from
the start. The enriching oil is therefore a mixture of all the oils used.

The second, longer, is formulated on a basis of a gramme of oil for each gramme of soda. A
choice can also be made as to the quantity and quality of the additional oil that is mixed in at
the end of the preparation of the soap mix.
The choice of this enriching oil is particularly important as it forms the protective film for the
skin and gives the individual character to the soap. This is the method we have chosen.
