Liquid Paraffin (Mineral Oil) – Grades, Specifications & Uses

Liquid paraffin is a clear, refined mineral oil used in pharmaceutical, cosmetic, personal care, food-processing, and industrial products. It has a smooth oily texture, very low odor, good chemical stability, and excellent resistance to water. Depending on the market, the same or closely related material may also be sold as mineral oil, paraffin oil, white mineral oil, or liquid paraffin oil.

Although the product looks simple, choosing the right grade matters. A material intended for an industrial lubricant does not have the same quality requirements as one intended for a cosmetic or pharmaceutical formulation. Buyers who also work with semi-solid petroleum products can compare petroleum jelly products with mineral-oil grades to select the right texture for their formulation. Basekim supplies liquid paraffin for bulk industrial and commercial orders in different grades and packaging options.

What Is Liquid Paraffin?

Liquid paraffin is a mixture of highly refined liquid hydrocarbons obtained from petroleum. After refining and purification, the material normally becomes clear, colorless, stable, and almost odorless.

Its main value comes from its simple performance. It spreads easily, provides lubrication, does not mix with water, and remains stable in many formulations.

This makes it useful in products as different as skin creams, pharmaceutical ointments, rubber compounds, textile oils, polishes, and industrial lubricants.

It is also closely related to white oil. In practice, the names used by suppliers can vary according to country, viscosity, purity, and end use. Therefore, buyers should compare the technical specification rather than relying only on the product name.

Is Liquid Paraffin the Same as Mineral Oil?

This is one of the most common questions about the product.

In many commercial markets, liquid paraffin and mineral oil refer to the same type of highly refined petroleum oil. The term white mineral oil is also widely used for highly refined, clear grades.

However, the name alone does not tell you everything about the material.

Two mineral oils may have different:

• Viscosity

• Density

• Flash point

• Purity

• Color

• Pour point

• Regulatory grade

• Intended use

For this reason, the TDS and product grade are more important than the commercial name.

The term paraffin oil is also commonly used for this family of products, particularly in industrial and regional markets.

Main Properties

A good-quality refined mineral oil normally offers a combination of stability, lubrication, and clean appearance.

Typical characteristics include:

• Clear and colorless appearance

• Very mild or almost no odor

• Smooth oily texture

• Insolubility in water

• Good spreading ability

• High chemical stability

• Good resistance to oxidation

• Long storage life

• Controlled viscosity

• Low reactivity under normal conditions

These properties explain why refined mineral oil products can serve both consumer formulations and industrial manufacturing.

Typical Specifications

There is no single specification that covers every grade. In particular, viscosity can change significantly depending on whether the buyer needs a light or heavy product.

A typical commercial grade may be evaluated using the following properties:

For one commonly supplied viscosity range, a typical analysis may look like this:

These figures should not replace the TDS of the actual shipment. Buyers should always request the specification that matches the grade they intend to purchase.

Available Grades

The easiest way to understand mineral oil is to look at the market it is designed for.

Pharmaceutical Grade

Pharmaceutical-grade material goes through strict refining and quality control.

Depending on the required standard, it may be used as a base or ingredient in products such as:

• Ointments

• Creams

• Topical formulations

• Pharmaceutical preparations

Some markets search specifically for Liquid Paraffin IP, which normally refers to material produced to meet an applicable Indian Pharmacopoeia specification.

Other markets may request USP, BP, or Ph. Eur. requirements.

Therefore, an enquiry for “pharmaceutical liquid paraffin” should include the required standard. The words pharmaceutical grade alone are not enough for final approval.

Cosmetic Grade

Cosmetic mineral oil is widely used because of its smooth feel and ability to form a thin protective layer.

Common products include:

• Body lotions

• Moisturizing creams

• Baby oils

• Cleansers

• Hair-care products

• Massage oils

• Makeup products

• Balms

It can improve spreadability and help reduce moisture loss from the skin.

When a manufacturer requires a thicker, semi-solid material instead of a liquid oil, petroleum-based personal care materials may provide a more suitable texture.

Food-Contact and Food-Grade Applications

Highly refined mineral oils can also be produced for specific food-processing or food-contact applications.

Depending on applicable regulations, suitable grades may serve as:

• Processing lubricants

• Release agents

• Equipment lubricants

• Protective processing materials

However, an industrial grade should never be assumed to be suitable for food use.

The buyer should always specify the intended application and required standard before ordering.

Industrial Grade

Industrial grades serve applications where technical performance matters more than pharmaceutical or cosmetic purity.

They are used in areas such as:

• Textile processing

• Rubber manufacturing

• Plastic production

• Metalworking

• Paper processing

• Polishes

• Leather products

• Cable compounds

• Lubricating formulations

For these applications, buyers often focus on viscosity, stability, flash point, color, and price.

Light and Heavy Mineral Oil

Viscosity is one of the main differences between commercial grades.

Light mineral oil flows easily and spreads quickly. Manufacturers often choose it for cosmetic formulations, light lubrication, carrier oils, and processes that require a thinner fluid.

Heavy mineral oil, on the other hand, has a higher viscosity. It creates a thicker oil film and may work better in industrial lubricants, protective products, and formulations that need more body.

The right choice depends on the process.

A low-viscosity grade is not automatically better, and a heavy grade is not always stronger. The viscosity simply needs to match the intended use.

How Is It Produced?

The production process begins with selected petroleum fractions.

First, refiners separate different components according to their physical properties. Some heavier petroleum streams may later be processed into waxes, lubricants, or base oil products.

The mineral-oil stream then goes through purification steps. Depending on the refinery and target quality, these steps can include:

• Distillation

• Hydrotreating

• Hydrogenation

• Filtration

• Dewaxing

• Finishing treatments

These processes reduce unwanted color, odor, sulfur compounds, and other impurities.

After purification, manufacturers control viscosity and other properties to produce the required final grade.

Uses in Pharmaceutical Products

Pharmaceutical applications are an important source of search demand for this product.

Suitable grades may be used as carriers or bases in creams, ointments, and topical preparations. The oil can provide a smooth texture and help create a protective layer in the finished formulation.

However, pharmaceutical use requires more than simply choosing a clear mineral oil.

Manufacturers should verify:

• Required pharmacopoeia

• Purity

• Viscosity

• Product documentation

• Manufacturing standard

• Local regulations

Internal medicinal applications should only use products specifically approved and formulated for that purpose.

Uses in Cosmetics and Personal Care

Cosmetics represent one of the best-known markets for mineral oil.

Formulators value it because it has a smooth feel, spreads well, and remains stable for a long time.

It may be found in:

• Moisturizers

• Body oils

• Baby oils

• Skin creams

• Hair products

• Cleansing products

• Massage products

• Makeup

The selected viscosity can affect how the final product feels. Light grades produce a thinner feel, while heavier grades create a richer texture.

Industrial Uses

Outside personal care, the product has a broad industrial market.

Textile Industry

Mineral oil may be used in textile processing and lubrication systems where smooth fiber movement is required.

Rubber and Plastics

It can act as a processing oil or formulation component in selected rubber and plastic products.

Metalworking

Suitable industrial grades may provide lubrication and surface protection in selected metalworking systems.

Paper and Packaging

Manufacturers can use refined oils as processing aids or components in specialty formulations.

Polishes and Protective Products

Because the oil spreads easily and repels water, it can be used in selected wood, leather, metal, and surface-care products.

Liquid Paraffin vs Petroleum Jelly

These two materials come from petroleum processing, but their physical form is very different.

Liquid paraffin is a flowing oil, while petroleum jelly is semi-solid.

As a result, they perform different jobs.

Therefore, manufacturers should choose based on the texture and function required in the final product.

Packaging for Bulk Orders

Packaging depends on order size, destination, and grade.

Common export options include:

• 180 kg steel drums

• Flexitanks

• ISO tanks

Drums are useful when buyers need easier handling or smaller volumes. In contrast, flexitanks and ISO tanks can be more practical for large industrial shipments.

Before shipment, buyers should confirm the net weight, loading quantity, drum condition, labeling, and required export documents.

Price and Buying Factors

There is no reliable fixed price for all grades.

The final liquid paraffin price depends on:

• Viscosity

• Grade

• Purity

• Required standard

• Quantity

• Packaging

• Origin

• Freight

• Destination

• Incoterm

• Petroleum market conditions

Small quantities may sometimes be quoted as a price per litre, while international bulk business is more commonly calculated by drum, kilogram, or metric ton.

For a useful quotation, buyers should provide the required viscosity or TDS, quantity, packaging, destination port, and preferred shipping term.

Storage and Handling

Store the product in clean, closed containers and protect it from contamination.

A cool, dry storage area is normally suitable. In addition, containers should remain closed when the material is not in use.

Workers should follow the current SDS and local workplace rules.

Although highly refined grades have a long history of use in sensitive applications, the safety and suitability of a product always depend on its grade, purity, exposure, and intended use.

What Buyers Should Check Before Ordering

A simple request for “mineral oil” may not provide enough information for a correct quotation.

Before ordering, buyers should ideally confirm:

• Intended application

• Required grade

• Light or heavy viscosity

• Target viscosity value

• Required pharmaceutical or food standard

• Quantity

• Packaging

• Destination

• SDS and TDS requirements

This information helps avoid receiving a technically unsuitable grade.
