CAS No. 4181-05-9 is a chemical substance known as Stearic Acid. It is a type of fatty acid derived from animal and vegetable fats and oils. It is odorless, colorless and insoluble in water. It has a wide range of uses in various industries, such as cosmetics, detergents, pharmaceuticals, rubber, paper, food and others.
Stearic Acid is a white, waxy, solid material with a faint, characteristic odor. It is composed of a mixture of saturated and unsaturated fatty acids, primarily stearic and palmitic acid. It is commonly used as an emulsifier, stabilizer, surfactant and thickener in a variety of industrial and consumer applications.
In the cosmetics industry, Stearic Acid is used as an emulsifying agent, as it helps to keep fats and oils mixed with water. It is also used as a surfactant to reduce the surface tension of water, allowing it to mix with oils and dirt, making it easier to rinse away. Additionally, it is used to soften and thicken the product, helping it to spread on the skin more easily.
In the detergents industry, Stearic Acid is used to form stable mixtures with soap, preventing it from separating out of the solution and creating foam. It also helps to reduce the surface tension of water, allowing better cleaning action.
In the pharmaceutical industry, Stearic Acid is used as an emulsifying agent to facilitate the dissolution of drugs in water. It is also used as a tablet binder, a lubricant to prevent sticking in the manufacturing process, and a coating to control the release of the drug.
In the rubber industry, Stearic Acid is used as a release agent and plasticizer. It helps to reduce the surface tension of rubber, allowing it to flow better and adhere better to the mold.
In the paper industry, Stearic Acid is used as an emulsifying agent to increase the wet strength of paper and to reduce the settling rate of fillers.
In the food industry, Stearic Acid is used as an emulsifying agent, helping to keep fats and oils mixed with water. It is also used as a dough conditioner, helping to increase the dough's elasticity and strength. Additionally, it is used as a crystallization inhibitor and a coating agent, helping to prevent crystallization.
Overall, Stearic Acid is a widely used chemical substance, with a wide range of applications in various industries. It has a number of beneficial properties, including emulsifying, surfactant, stabilizing, thickening, and lubricating properties, making it a valuable commodity in many industries.
