Determining the Quality of Palm Stearic Oil Fatty Acid (PSOFA) at PT. Socimas Medan: Peroxide Test and Melting Point Analysis

Introduction

Palm Stearic Oil Fatty Acid (PSOFA) is a crucial raw material used in various industries, including the production of soap, cosmetics, and lubricants. PT. Socimas Medan, a leading Oleochemical Product-producing company, produces high-quality PSOFA that meets the stringent standards of the industry. In this article, we will discuss the importance of determining the peroxide value and melting point of PSOFA, and how these parameters contribute to the overall quality of the product.

Understanding Peroxide Value and Melting Point

Peroxide value is a critical parameter that measures the number of milliencivalents of peroxide in 1000 grams of fat. This value is an indicator of the oxidative stability of the PSOFA, which is essential for maintaining its quality and shelf life. On the other hand, the melting point is the temperature at which the fat turns completely liquid or undergoes a phase change from solid to liquid. This parameter is crucial for determining the physical properties of PSOFA, such as its viscosity and flow behavior.

Determining Peroxide Value through Iodometric Titration

The iodometric titration method is a widely used technique for determining the peroxide value of PSOFA. This method involves measuring the amount of peroxide in the sample using an iodine solution. The reaction between the peroxide and iodine results in the formation of iodide ions, which are then titrated with a standard solution of sodium thiosulfate. The amount of sodium thiosulfate required to neutralize the iodide ions is directly proportional to the peroxide value of the sample.

Determining Melting Point through Capillary Tube Heating

To determine the melting point of PSOFA, a sample is placed in a capillary tube and heated until it melts. The temperature at which the sample undergoes a phase change from solid to liquid is recorded as the melting point. This parameter is critical for determining the physical properties of PSOFA, such as its viscosity and flow behavior.

Results and Discussion

The results of the research on PSOFA products at PT. Socimas Medan indicate that the peroxide values ​​ranged from 0.59 to 0.99 mEQ. These results still meet the standards set by PT. Socimas Medan, which is a maximum of 5 mEQ. This indicates that the PSOFA produced has good quality and can still be used in various industrial applications.

Meanwhile, the melting point obtained from the PSOFA sample ranged from 51.6 to 51.8oC. These results also meet the established standards of 47-57oC. The appropriate melting point indicates that PSOFA has optimal physical properties to be applied to various products, such as soap, cosmetics, and lubricants.

Conclusion

Testing peroxide values ​​and regular melting points is very important to ensure that the PSOFA produced by PT. Socimas Medan still meets the established quality standards. This is not only important to maintain the company's reputation, but also to ensure the safety and quality of the final product that uses PSOFA as a raw material.

The results of this test indicate that the PSOFA produced by PT. Socimas Medan has good quality and meets established standards. Thus, the company can guarantee the quality of its products and meet the increasingly high market needs of safe and quality oleochemical products.
