Liquid Paraffin Grades: Industrial, Cosmetic, and Food Uses

Liquid paraffin, also known as mineral oil, is a versatile petroleum derivative. It comes in different grades depending on its level of refinement and purity. The three main types are industrial, cosmetic (pharmaceutical), and food grade. Understanding their differences is essential for safe and effective use.

Industrial Grade Liquid Paraffin

Industrial grade is less refined and contains higher levels of impurities compared to other grades. It is mainly used where direct contact with humans or food is not required.

Applications:

• Lubricants for machinery

• Plastic and rubber manufacturing

• Textile industry as a softener

• Agricultural sprays and formulations

This grade is cost-effective but not suitable for cosmetic or food applications.

Cosmetic (Pharmaceutical) Grade Liquid Paraffin

Cosmetic or pharmaceutical grade liquid paraffin undergoes a higher level of purification. It is colorless, odorless, and complies with medical and cosmetic safety standards.

Applications:

• Skin care products (lotions, creams, baby oils)

• Hair care formulations

• Ointments and medical emulsions

• Therapeutic use in dermatology

Its stability and safety make it ideal for products that come in direct contact with skin.

Food Grade Liquid Paraffin

Food grade liquid paraffin is the most refined type, certified safe for direct or indirect contact with food. It is tasteless, odorless, and meets international regulations such as FDA and EU standards.

Applications:

• Food release agent in baking and confectionery

• Coating for fruits and vegetables to retain freshness

• Anti-caking agent in food processing

• Lubricant in food packaging machinery

This grade ensures consumer safety and complies with strict global standards.

Comparison Overview (Text Format)

• Industrial grade: Moderately refined, not safe for skin or food. Mainly used in lubricants, plastics, textiles, and agriculture.

• Cosmetic grade: Highly refined, safe for skin. Common in lotions, creams, ointments, and hair care products.

• Food grade: Most refined, safe for consumption. Used in food coatings, anti-caking agents, and packaging applications.

Choosing the Right Grade

When selecting liquid paraffin, the end application is the key factor:

• Use industrial grade for technical and manufacturing processes.

• Use cosmetic grade for skin, hair, and medical products.

• Use food grade for any food-related application where consumer safety is critical.

Conclusion

Liquid paraffin is a valuable raw material with applications ranging from industry to health and food. By choosing the right grade—industrial, cosmetic, or food—businesses can ensure both efficiency and compliance with safety standards.
