Sodium hydroxide better known as caustic soda seems to mismatch with other natural ingredients? In fact, this is authorized in organic products because it doesn’t pose any problems under the conditions of the regulations. In addition, this ingredient is essential to produce soaps. The making process to produce soap is a chemical reaction called saponification. During this process, soda completely reacts with fatty acids from oils or butters to produce natural glycerin and soap. The first way to saponify, used by the industry to make soap faster is to heat the preparation. With this method, at the end of the hot process, the soap is ready to use. But oils and butters are denatured and lose some of their properties with heat. The second way that we use at Neven, is cold saponification. After the making, the reaction continues for a month so it is absolutely not possible to use the soap during this period. But as a result of this process, the soap is naturally rich in glycerin which gives smoothness and hydration to your skin. Furthermore, vegetable oils and butters contain an unsaponifiable fraction which means these compounds don’t react with soda. These substances are very interesting because they have desired properties like antioxidant, nourishing, emollient, softening, and protective effects. Therefore the formula of the soap will give it unique properties that are not found in the industrial process.
