Soap requires two major raw materials: fat and alkali. The alkali most commonly used today is sodium hydroxide. Potassium hydroxide can also be used. Potassium-based soap creates a more water-soluble product than sodium-based (hard) soap, and so it is called "soft soap." Soft soap, alone or in combination with sodium-based soap, is commonly used in shaving products.
Animal fat in the past was obtained directly from a slaughterhouse and also from the sea animals ( for instance : whales). Modern soapmakers use fat that has been processed into fatty acids. This eliminates many impurities, and it produces as a byproduct water instead of glycerin. Many vegetable fats, including olive oil, palm kernel oil, and coconut oil, are also used in soap making.

Ingredients
Oils and fats for soap are compounds of glycerin and a fatty acid. When oils are mixed with an alkali, they form glycerin and the sodium salt of the fatty acid. The fatty acids required for soap making are supplied by tallow, grease, fish oils, and vegetable oils. The hardness, lathering qualities, and transparency of soap vary according to the combinations of fats and alkalis used as ingredients. An experienced soap crafter uses many combinations of oils.

Sodium hydroxide, water, heat energy and some ester.
Edited:
Ester is a compound formed through condensation reaction between an alcohol and carboxylic acid. The alcohol is glycerol and acid is fatty acid CH3(CH2)14COOH or CH3(CH2)12COOH

Fats and sodium hydroxide (NaOH). You may also want to add other things that will give fragrances.
