The product we are introducing here is Factory Supply Fatty Acids, Tallow Cas 61790 - 37 - 2. Fatty acids derived from tallow are a mixture of saturated and unsaturated fatty acids. The CAS number 61790 - 37 - 2 specifically identifies this type of tallow - derived fatty acids.
Typically, the fatty acid composition of tallow fatty acids includes palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1), and linoleic acid (C18:2). The physical properties of these fatty acids are as follows: they are usually in a solid or semi - solid state at room temperature, with a melting point ranging from 30°C to 60°C. They have a characteristic fatty odor. The acid value of these fatty acids is an important parameter, usually ranging from 190 to 205 mg KOH/g, which reflects the content of free fatty acids in the product. The iodine value, which indicates the degree of unsaturation, is typically between 40 and 60 g I₂/100g.
1. **Soap and Detergent Industry**: Tallow fatty acids are widely used in the production of soap. They react with alkalis such as sodium hydroxide or potassium hydroxide through saponification reactions to form soap. The long - chain fatty acids in tallow provide good cleansing properties and foam stability, making the soap effective in removing dirt and oil from the skin and various surfaces. In the detergent industry, they can also be used as raw materials for synthetic detergents, enhancing the emulsifying and dispersing capabilities of the products.
2. **Lubricant Industry**: They can be used as additives in lubricants. The polar groups of fatty acids can adsorb on metal surfaces, forming a thin protective film that reduces friction and wear between moving parts. This helps to improve the service life and performance of machinery and equipment.
3. **Cosmetics and Personal Care Products**: Due to their good emollient properties, tallow fatty acids are used in the formulation of creams, lotions, and lip balms. They can help to keep the skin hydrated, smooth, and soft, and prevent moisture loss.
1. **In Soap Production**: When using tallow fatty acids in soap - making, first, calculate the appropriate amount of alkali according to the acid value of the fatty acids. Then, slowly add the alkali solution to the melted fatty acids under stirring. The reaction temperature is usually maintained at around 80 - 100°C. Continuously stir until the reaction is complete, and then pour the mixture into molds for cooling and solidification.
2. **As a Lubricant Additive**: Dissolve the tallow fatty acids in a suitable base oil. The recommended dosage is usually between 1% and 5% by weight, depending on the specific application requirements. After dissolving, stir well to ensure uniform dispersion of the fatty acids in the base oil.
3. **In Cosmetics**: In the production of cosmetics, tallow fatty acids should be melted and mixed with other ingredients such as emulsifiers, water, and active substances at an appropriate temperature. The mixing process needs to be carried out under sterile conditions to ensure product quality.
1. **Soap Manufacturer Case**: A small - scale soap manufacturing company used our Factory Supply Fatty Acids, Tallow Cas 61790 - 37 - 2 in their soap production. They previously used a different source of fatty acids, but the soap had poor foam quality and a short shelf - life. After switching to our product, they found that the foam of the soap became richer and more stable. The soap also had a better texture and longer - lasting freshness. The company saw an increase in customer satisfaction and sales volume as a result.
2. **Lubricant Application Case**: An industrial equipment maintenance company added our tallow fatty acids to their lubricating oil for heavy - duty machinery. Before using our product, the machinery often suffered from excessive wear and tear, resulting in frequent breakdowns. After adding the fatty acids as an additive, the friction between the moving parts was significantly reduced. The machinery's operating temperature decreased, and the frequency of breakdowns was greatly reduced, saving a lot of maintenance costs for the company.
