[Chemical Knowledge]：Properties, uses, upstream and downstream raw materials, storage methods, clinical uses of liquid paraffin

Liquid paraffin properties

Liquid paraffin, also known as white oil, is a colorless, tasteless, odorless mineral oil. It is chemically stable, not easily oxidized, insoluble in water, but soluble in most organic solvents. The viscosity of liquid paraffin varies little with temperature, and has excellent lubricity and insulation. Due to its high purity and stability, liquid paraffin is not easy to change in chemical reactions, and is often used in applications where high purity and stability are required.

Liquid paraffin use

Liquid paraffin is widely used in many industries, including cosmetics, medicine, food and industry. In the cosmetics industry, liquid paraffin is used as a moisturizer, lubricant and matrix for the manufacture of moisturizers, lipsticks, creams and other products. In the field of medicine, liquid paraffin is used in the manufacture of pharmaceutical preparations such as ointments and creams, and as a lubricant for medical devices. In the food industry, liquid paraffin is used as a release agent, brightener and anti-sticking agent for the production of candy, cakes and other products. In industry, liquid paraffin is used as lubricating oil, cooling oil, cable oil, etc.

Liquid paraffin upstream and downstream raw materials

The upstream raw material of liquid paraffin is mainly petroleum, which is obtained by petroleum distillation and refining process. Specifically, after primary distillation of petroleum, light oil and heavy oil are obtained, and then further refined and decolorized, and finally liquid paraffin is obtained. The production process of liquid paraffin includes vacuum distillation, solvent dewaxing, clay refining and hydrofining.

The downstream products of liquid paraffin include various lubricants, cosmetics, pharmaceutical preparations and food additives. The downstream industry chain is long, covering multiple end consumer goods markets. Due to its stable chemical properties and wide application fields, liquid paraffin has high demand in the downstream market.

Liquid paraffin storage method

The storage requirements of liquid paraffin are strict to ensure its quality and safety. Liquid paraffin should be stored in a dry, cool, ventilated environment, avoid direct sunlight and high temperature. The storage container should be a well-sealed steel drum or plastic drum to prevent liquid paraffin from contacting with air and avoid oxidation and pollution. The storage environment should be away from fire and heat sources. Although liquid paraffin is chemically stable, it still has certain volatility and flammability at high temperatures.

Liquid paraffin safety and environmental protection

Liquid paraffin is considered a relatively safe chemical. It is stable at normal temperature and pressure, not easy to burn, and does not produce harmful gases. During use and storage, it is still necessary to pay attention to fire and explosion prevention and avoid contact with strong oxidants. Liquid paraffin has low toxicity and no irritation to human skin and mucous membranes, so it is widely used in cosmetics and medicine.

In terms of environmental protection, the biodegradability of liquid paraffin is poor, and it may cause pollution to water and soil after being discharged into the environment. Therefore, when waste liquid paraffin, appropriate treatment, such as recycling or centralized treatment, should be carried out to reduce the impact on the environment.

Liquid Paraffin Market Analysis

The market demand for liquid paraffin is affected by many factors, including the level of economic development, industrial production and consumer goods market demand. With the development of the global economy and the improvement of people's living standards, the demand for end products such as cosmetics, medicine and food is increasing, which promotes the growth of the liquid paraffin market.

Technological advances and process improvements have also contributed to the expansion of the application of liquid paraffin. The introduction of the new production process has improved the purity and quality of liquid paraffin, making it more competitive in high-end applications. There are also some challenges in the market, such as fluctuations in raw material prices and increasingly stringent environmental regulations, which may have an impact on the production and market of liquid paraffin.

Conclusion

As an important chemical raw material, liquid paraffin has stable chemical properties and a wide range of applications. Its upstream is mainly derived from petroleum, obtained through refining processes, while its downstream covers a number of end consumer markets. The storage method of liquid paraffin needs to be strictly controlled to ensure its quality and safety. Driven by market demand and technological progress, the application prospect of liquid paraffin is broad, but it also needs to face the challenges of raw material price fluctuation and environmental protection regulations. By continuously optimizing the production process and strengthening environmental management, the liquid paraffin industry is expected to continue to maintain a good development trend in the future.
