Abstract:
Natural oils and fats are the oldest raw materials used in the production
of surfactant, i.e. soap. Synthetic detergents have largely displaced soap as
a heavy-duty washing material, but soap - especially toilet and fine laundry
soap - continues to enjoy consumer popularity and is preferred where soft
water is available, whether from natural resources or by treatment. In many
countries, soap is still the primary washing product for domestic and commercial
laundering as well as personal hygiene.
