Soaps are sodium or potassium fatty acids salts, produced from the hydrolysis of fats in a chemical reaction called saponification. Each soap molecule has a long hydrocarbon chain, sometimes called its ‘tail’, with a carboxylate ‘head’.

What makes soap clear?
Transparent soap is simply hot process soap that uses solvents (sugar, glycerin and alcohol) to dissolve the soap crystals that form allowing light to pass, therefore creating transparency.
What makes soap float?
Tiny air bubbles trapped in the Ivory bar make bubbles, decreasing the density of the soap to less than the density of water. This increases the soap’s buoyancy.
What is hot process soap?
Similar to cold process soap, hot process soap is also made with oils and lye – but instead of stick blending until it hits trace (a thick batter) and being poured into a mold, it is mixed and heated in the slow cooker, somewhere between 140 degrees F and 176 degrees F.

How is soap made in laboratory?
Soap is made in the laboratory by the process of Saponification. The process involves reacting a vegetable oil like palm oil or olive oil with an alkali like Sodium Hydroxide. This reaction is exothermic in nature, liberating heat during the reaction.
Which acid is used in soap?
Sodium hydroxide is employed as the saponification alkali for most soap now produced. Soap may also be manufactured with potassium hydroxide (caustic potash) as the alkali.
Which is soft soap?
Soft soap may refer to: Soap that is liquid or easily soluble, usually made by saponification with potassium instead of the more typical sodium hydroxide. Softsoap, trade name of a liquid soap product.
How long does it take to make soap?
There is no heating involved, but the soap will need 4 to 6 weeks to cure, so that saponification is complete and all the lye is gone. Hot process: This also involves making soap from scratch. Heat, from a crockpot for example, is used to speed up the saponification, so the soap can be ready in as little as a week.
