What is liquid paraffin?
This compound does not have a specific formula due to its mixture of saturated hydrocarbons in its structure and is generally represented by the formula CnH2n+2. In the solid state, it is a waxy, white particle, but in the liquid state, it is a colorless, odorless, and tasteless liquid, and due to its hydrocarbon structure, it is present in the form of oil. These compounds are the main components of oil and natural gas. Those with less than 5 carbon atoms per molecule are usually gases at room temperature, while those with between 5 and 15 carbon atoms are usually liquids. Straight-chain types with more than 15 carbon atoms per molecule are solids at room temperature. These compounds also have higher stability than olefins.

Production Method of Liquid Paraffin
The raw material of this compound, slaked wax, is a mixture of oil and wax and a by-product of refining lubricating oil. First, the oil is separated from the slaked wax (deoiling or dewaxing) and separated by crystallization. Generally, the slaked wax is heated, mixed with a solvent such as a ketone, and then cooled. The wax is then crystallized from the solution, leaving the remaining oil before being filtered in two forms:
- Solid – wax plus some solvent
- Liquid – oil and solvent
The product wax may be further refined to remove any color and odor. It is then blended to achieve the desired products with specific properties such as penetration and melting point. Paraffin wax is then supplied in liquid or solid form.
Applications of liquid paraffin
The main use of liquid paraffin is in the medical and pharmaceutical industries and in the production of cosmetic and health products. We will examine these uses of this substance in the following.
Medicine
This compound is used as a laxative and lubricant in children and is one of the effective treatments for treating constipation and encopresis. Symptoms such as abdominal problems, bloating, diarrhea, etc. are not related to this drug and the function of this substance is different from osmotic laxatives.
In general, this medicine acts as an oily layer covering the intestines and treating constipation. It is also effective in treating hemorrhoid problems and pain.
Cosmetics
In cosmetic products, this compound is used as a natural emollient. Because it has a low melting point, it is applied to the hands and feet, which is known as paraffin therapy for hands and feet. It causes gentle heat to be transferred to the skin and increases blood flow in that area. It also acts as a natural emollient and softens the skin. This substance is used in many beauty salons.
Paraffin is used in many beauty products because it is inexpensive. Paraffin is a good product for the skin and increases its moisture; it also continues to increase moisture levels after the treatment is completed. It also helps open pores and remove dead skin cells, making the skin look fresher and smoother. It also has a long history of treating many physical ailments such as arthritis and increasing blood flow.
Global Market:
The global market value of this material in 2022 was $8.2 billion and is expected to reach $13.39 billion by 2032, growing at a CAGR of 5.60%. This material has many applications in various industries such as cosmetics, candle manufacturing, etc. Overall, its versatile properties such as smooth texture, formulation retention, and compatibility with various formulations make this material an ideal ingredient for skin and hair care products.
Based on the geographical region, North America, Europe, and Asia Pacific are growing faster than other regions. The strengths of these regions are candle manufacturing, packaging products, and cosmetics. Among all regions, Asia Pacific witnessed good growth due to the increasing demand for this material in the production of candle, packaging, and cosmetics products. Among all countries, India and China were highly influential in the growth of the market for this material due to the demand and production for cosmetics.
MSDS, Safety Tips and Dangers of Paraffin:
This compound is classified as toxic and causes irritation to the skin and eyes when in contact with them. High concentrations of its vapors may cause headaches, numbness, dizziness, throat and eye irritation. This compound is also flammable and produces carbon monoxide, carbon dioxide and other toxic gases when heated. Therefore, safety precautions should be observed when working with it, including the use of a gown, goggles, gloves and a mask. In case of any contact with this substance, the following should be observed:
- Eyes: Contact with this substance will cause irritation and redness. In case of contact, rinse the eyes immediately with water. Remove lenses and flush eyes with water for 15 minutes, opening and closing eyelids while flushing.
- Skin: Repeated or prolonged contact may cause redness, irritation, and peeling of the skin (dermatitis). Normal care and personal hygiene usually prevent skin reactions. In case of skin contact, remove contaminated clothing and wash skin thoroughly with soap and water.
- Inhalation: Exposure to the lungs, or prolonged inhalation of dust or vomiting after ingestion, can cause serious lung damage and possibly death. If inhaled, remove to fresh air and oxygen and seek medical attention immediately.
- Ingestion: Exposure to vapors and ingestion may cause headache and drowsiness. If you swallow this product, rinse your mouth with water and see a doctor.
Greatly reduce the risks of working with this chemical compound by following safety precautions.
