2. CHEMICALS
(a) Oil – The oil commonly used for soap production are:
i. Palm Kernel oil
ii. Fatty oil

(c) Soda ash– Increases the quantity of the soap
(d) Sodium sulphate – Increases the quantity of the soap and acts as the foaming agent.
(e) Kaoline – It is a forming agent.
(f) Silicate – It is a shining and binding agent.
(g) Colourant – This determines the colour of the soap.

The hydrometer reading should be 1200.

(b) Soda ash + sodium sulphate
One cup of Soduim Bi-carbonate plus one-eight cup sodium sulphate plus four cups of water (i.e. 1 sodium Bi-carbonate + 1/8 soduim sulphate plus four cups of water) are dissolved for at least 24 hours.
The hydrometer reading should be at 1200.
