![]() The greater the surface tension, the cleaner an object will be when washed with that solution. Surface tension measures how difficult a liquid or gas is to penetrate another substance. The cleaning ability of liquid soap can be improved with industrial salt by increasing its surface tension. Instead, turn it into a new product such as bath salts or laundry detergent. If you accidentally add too much salt, or if your soap seizes, do not discard it. Too much salt can cause your soap to be too complex and cause a condition known as "seizing." Seizing occurs when the soap becomes so thick after adding salt that it cannot be poured into a mold. When you add more salt to your soap recipe, you increase salt concentration. At the same time, too much salt will inhibit foam production altogether, making cleaning difficult due to a lack of friction from rubbing hands together or against an object. Too little salt will result in too much foam formation. Surfactants form bubbles when agitated by rubbing hands together or other movements against an object such as a washcloth or sponge. To prevent this from occurring, industrial salt is added to soap solutions, making them harder.Īnother essential function of industrial salt in liquid soap formulation is to regulate bubbles formed by surfactants or foaming agents. This will lead to a decrease in the cleansing power of the soap solution and also give it a cloudy appearance. If a soap solution is made using hard water, insoluble soap scum will be formed due to the reaction between the metallic ions present in hard water and the free fatty acids present in the soap. ![]() The hardness of water depends on dissolved salts and other minerals in the water. Stir the salt into the soap until it is completely dissolved. If you make liquid soap from scratch, add 2 tsp of table salt after the soap has cooled down and before you add fragrance. The soap does not require a preservative if you use it within about two weeks, but the salt will help the soap last much longer. The primary function of industrial salt in liquid soap is to work as a preservative. The Handcrafted Soapmakers Guild notes that adding industrial salt to liquid soaps increases lather without increasing the number of bubbles. The increased hardness means that more bubbles are produced, leading to more lather. The amount of lather produced by a bar or liquid soap is directly related to how much the soap has been hardened. This can be important if you are making a big batch of soap or live in an area that is especially hot and humid because higher temperatures and humidity can lead to a faster reaction in saponification. In the cold process of soapmaking, salt stabilizes the lye solution by helping it cool down evenly and more quickly, which shortens the time required for saponification in the soap mixture. This can prevent any undesirable discoloration or chemical reactions in your soap products that would lead to quality issues for your customers. Since salt is neutral, it can help bring the acidity or basicity levels in a liquid back into balance after adding too much acid or base to a solution. In addition to its ability to thicken liquids, salt can also be used to adjust the pH balance of soap products. Sodium chloride is commonly used to thicken solutions because it is inexpensive and can help reduce the amount of surfactant needed to produce an effective cleaning solution compared to other types of salt. Salt can help increase the viscosity of a liquid solution, which makes it a critical ingredient in many liquid soaps and detergents. One of the most common industrial uses for salt is a thickening agent. Industrial salt is often used as a de-mineralizing or de-chlorinating agent to remove minerals, iron, aluminum, and chlorine from the water solution in the industrial salt soap dispensing process. It can be used in the plant to produce a concentrated product which can then be diluted in different ways depending on the specific application. ![]() Industrial salt is an indispensable agent in the manufacturing of liquid soap. The function of industrial salt in liquid soap is twofold - it changes how the chemical itself looks and how the consumer perceives a product.
