Essential and fragrance oils are added at light trace. Objective: To compare the foaming capacity of various soaps. Contents II Page No. This alkali-fat mixture is stirred until "trace". The presence of such salts makes the water hard and the water is called hard water. The most popular soap making process today is the cold process method, where fats such as olive oil react with strong alkaline solution, while some soapers use the historical hot process. Handmade soap differs from industrial soap in that, usually, an excess of fat is sometimes used to consume the alkali (super fatting), and in that the glycerin is not removed, leaving a naturally moisturizing soap and not pure detergent. Aim: Study the effect of the addition of Sodium Carbonate (Washing Soda) on the foaming capacity of different soap solutions. a detailed investigatory project on the preparation of soap for class 12 final practical exam.. this project received full marks from the external examiner.

It is easier with the pH strips as they show the exact stage of soap formation and completion of the reaction between sodium hydroxide and oils. Cationic Detergents:-These detergents are so named because a major part of their molecules are cations and cationic part is involved in the cleanising action. They do not work well with hard water, acidic […] The washing ability of soap depends on foaming capacity, as well as the water used in cleaning. Often, emollients such as jojoba oil or Shea butter are added 'at trace' (the point at which the saponification process is sufficiently advanced that the soap has begun to thicken), after most of the oils have saponified, so that they remain unreacted in the finished soap.

Now customize the name of a clipboard to store your clips. These salts thus make the soap inefficient in its cleaning action. Sodium salts of fatty acids are known as hard soaps while the potassium salts of fatty acids are known as soft soaps. Soap is an anionic surfactant used in conjunction with water for washing and cleaning, which historically comes either in solid bars or in the form of a viscous liquid. The salts of Ca and Mg disrupt the formation of micelle formation. Once both substances have cooled to approximately 100-110°F (37-43°C), and are no more than 10°F (~5.5°C) apart, they may be combined. After saponification has occurred, the soap is sometimes precipitated from the solution by adding salt, and the excess liquid drained off. Soaps are the Na and K salts of higher fatty acids such as Palmitic acid, Stearic acid and Oleic acid. Soaps are sodium or potassium salts of fatty acids which are formed by hydrolysis of fats and oils.
