Everything You Should Know About High Viscosity Oils

Different types of mineral oils are everywhere in daily life, from baby oil, engine lubrication oils to high viscosity oils and many more. In fact, the United States is the world’s number one producer and consumer of mineral oil, representing an 18% share. However, despite oil being such a constant presence in today’s society, many consumers don’t fully understand oils and where they are used. This beginner’s guide to high viscosity oils will help you understand where they’re used and what makes an oil count as high-viscosity.

What Does High Viscosity Mean?

Generally speaking, viscosity refers to the thickness of a liquid. This quality impacts how the liquid moves and flows, as well as what it can be used for. High viscosity liquids are thicker, such as syrup, while low viscosity liquids are thinner, like water. The chemical makeup of a liquid determines its viscosity, as well as defining potential applications. High viscosity oils refer to higher molecular weight (longer molecules), lower volatility oils that are ‘thicker’ than others.

How Are High Viscosity Oils Used?

While many people think of oils as a cooking ingredient or as motor oils, high viscosity oils are used in more specialized applications. The advantage of high viscosity oils is that they have longer molecules and higher boiling point which means that they stay where they are put. Lighter oils evaporate in high-temperature applications like baking or as automotive soft-touch interior components. Using high viscosity oils mean that the soft-touch parts remain soft because the oil remains in the parts even through years of high-temperature use (think hot summer interiors of cars). Another excellent application for high viscosity oil is as a grease component that can handle heat.

High viscosity white oils can also be used to create food-grade items. The superior stability of the high viscosity white oil and its long molecules reduce migration to the surface of rubberlike plastic parts that can be used for food contact.

Windmill bearing lubricants are a specialty lubricant application that requires high viscosity where normal mineral oils with viscosity boosting additives may not perform as well as naturally higher viscosity mineral oil.

What About Low Viscosity Oils?

Low viscosity oils also play their part in manufacturing and nearly every industry. Mineral oil applications can include acting as a mold release agent, a catalyst carrier oil, dust control, a pigment dispersing agent, and more.

For example, low viscosity oils are essential in metal rolling, oil drilling and manufacturing many food-grade items. However, the potential applications determine what viscosity is needed. While low viscosity mineral oils are an essential part of many operations, their uses differ from those of high viscosity oils.

Understanding the differences between high viscosity oils and low viscosity oils can be helpful in selecting the right oil for your industrial needs.

Base Oil Groups: Understanding Properties and Applications

Lubricants play an integral role in how our world functions. Automobile and truck engines the biggest consumers of lubricants worldwide, using 20 million tons per year, which means that motor oils often help to drive this industry. They’re also used in industrial applications, cooking, the medical field, and virtually any other sector you can imagine. Just about every lubricant begins as a base oil, which is typically produced during the crude oil refining process.

There are numerous types of premium base oils that you can obtain from base oil suppliers. But in order to determine which type of base oil will best suit your application, you’ll want to learn a bit more about what’s available to you. The American Petroleum Institute (or API) has categorized the different types of base oils into five distinctive groups. Understanding these class distinctions will prove essential when conducting business with base oil suppliers to choose the right product.

The characteristics of base oils that are used to determine their performance may include:

  • Pour point
  • Viscosity and viscosity index
  • Purity
  • Volatility
  • Thermal stability
  • Hydrolytic stability (water resistance)
  • Oxidation
  • Sulfur and saturate content

Group I

Generally speaking, Group I base oils are made using solvent extraction or solvent refining processes, which are meant to remove any undesirable aspects of the original oil. When you work with base oil plants to obtain products from this group, these oils will be classified as having less than 90% saturates and greater than 0.03% sulfur. Their viscosity index range will be anywhere from 80 to 120 and their temperature range extends from 32 to 150 degrees Fahrenheit. Although these are among the most affordable base oils available and make up the largest category in the global marketplace, the demand for these oils is on the decline. However, they are still readily used in certain engine oils, industrial applications, and marine lubricants.

Group II

Like Group I base oils, Group II base oils are considered to be mineral oils. They contain more than 90% saturates and less than 0.03% sulfur, while offering a viscosity index range of 80 to 120. They tend to have improved anti-oxidation properties, as compared to Group I oils. That said, they are more expensive and are manufactured in a more complex way (through a process called hydrocracking). But since the vast majority of lubricants used worldwide can be made from Group II base oils, it makes sense that this particular category is the most popular.

Group III

Considered by many to be the best grade of petroleum base oil, Group III oils contain greater than 90% saturates and less than 0.03% sulfur. One of the biggest differences is that their viscosity index range extends above 120. While they’re made in similar ways to Group I oils, Group III oil creation involves higher pressures and temperatures. As a result, these oils are purer and more desirable. Group III base oils are becoming more prevalent, particularly as automobile fuel economy increases in importance.

Group IV

Unlike the first three base oil categories, which are all mineral oils, Group IV base oils are polyalphaolefins — synthetic base oils that are created through a much different process (aptly called synthesizing). As your base oil supplier will tell you, this can be used to create products with wider temperature ranges and thermal stability in challenging conditions. In fact, their viscosity index ranges may reach 140. They also have improved oxidation stability. But while this is the most readily used type of synthetic base oil, it’s important to know that the solubility, lubricity, and strength of these oils can be a detriment. And because of cost and availability, they will never be as widely used as the mineral base oils outlined above.

Group V

This is the group with the most variety, as it’s the catch-all category for all other base oils (including polyesters, diesters, polyalkylene gycols, silicones, naphthenic oils, phosphate esters, biolubes, and more). Essentially, if the oil is synthetic and is not a polyalphaolefin, it’s classified as a Group V oil. In many cases, Group V oils are used as a supplement to other base oils, rather than being used as a base on their own.

3 Industries That Rely On White Oils

White oils are invaluable to our modern day society. Although they’re actually clear, not white, they are extremely pure, stable, colorless, odorless, non-toxic, and chemically inert highly refined mineral oils. As a result of these beneficial properties, they are used in a wide variety of industries. Let’s take a look at three industries that heavily rely on white mineral oils to do their jobs.

  • Pharmaceutical/cosmetic: Unsurprisingly, oils are quite important in the health and beauty business. Because they offer excellent hydration and emollience (or softness), certain white oils are immensely compatible with skin; low irritancy and comedogenicity (which means they have been shown to cause breakouts) make these white mineral oils ideal for cosmetic solutions.
  • Phytosanitary: The phytosanitary industry has to do with the protection of crops, plants, trees, and livestock from harmful insects and pests. White oils play a key role in creating the products — from pesticides to insecticides to fungicides — that are used to do just that. Many white oil manufacturers are held to the high standards of the Pharmacopoeias, an official publication that contains a list of medicinal drugs with their effects and directions for their use, to ensure that the household insecticides, tree-protecting sprays, cattle sprays, crop pesticides, and plant sprays don’t negatively impact the people that will inevitably consume them.
  • Polystyrene: Polystyrene is a type of polymer with thermoplastic properties used for molding and extrusion. The demand of such a vast industry requires its white oil to offer reliable filling of complex molds, good mold-release properties to help control surface finish, easy transforming abilities, and consistent optical and mechanical isotropy in the finished products. Paraffinic oil is often used in the manufacture of polystyrene, explaining why the U.S. produced 29 million barrels of it in 2018.

White oils are held to extremely high standards to ensure compliance with the stringent food and pharmaceutical regulations.  The supply line itself is vital: if white oil manufacturers aren’t sending quality mineral oil to their clients, then their clients can’t produce quality products. Finding the best white oil manufacturer for your needs is one of the best investments you can make for your company.

Mineral Oils – Types Available and Their Applications

Oils are essential ingredients in an extensive range of products. They can be found in concentrations between 1% and 99% in creams, lotions, cleansers, sunscreens, makeup, gels, and vaseline, along with many lubrication products. Therefore, finding quality mineral oil ingredients is paramount for manufacturers.

Base Oils

The quality of base oil depends on the manufacturing process. As an authorized distributor for Chevron, Renkert Oil supplies premium base oils evaluated to be exceptionally stable in oxidation, low in volatility at given grades of viscosity, and essentially free of sulfur. These base oils are ideal choices when it comes to choosing material for a variety of different products, encompassing automotive purposes as motor oils, industrial processes, and feedstock for food grade white oils, amongst other uses.

Renoil White Mineral Oils

Renoil white mineral oils are free of color, odor, and taste – a mixture of saturated paraffinic and naphthenic hydrocarbons with a range of viscosity from 60 to 1700 SUS at a temperature of 100 degrees F.

Applications may include use in products involving direct contact with food, prolonged contact with skin, and minimization of odor and stains.

Renoil Low Volatility Mineral Oils

Low volatility mineral oils are paraffinic and highly refined. Their properties include extremely low volatility, low temperature fluidity, and high viscosity despite the absence of thickeners. These oils are also odorless and tasteless, and colorless.

Applications may include use in products such as low fogging thermoplastic elastomer extenders, grease components, lubricants for high and low temperatures, and oils for heat transfer, compressors, and wind turbines.

Renoil High Viscosity White Mineral Oils

High viscosity white mineral oils are clear and highly refined with low volatility and extremely high stability in oxidation. They are odorless, tasteless, colorless, chemically inert, and UV stable.

Applications often involve the addition of these oils into plastics, either as internal or external lubricants or as polymer extenders or softeners. These food grade white oils are used in mold release agents, pigment dispersing agents, catalyst carrier oils in polymer production, heat transfer oils, and low fogging plasticizers.

Process Oils

Process oils provide high stability in oxidation and low volatility for its viscosity grade. Although they may have slight color, the color remains consistent despite exposure to UV or to heat.

These oils reduce mixing time, generate less heat, and maximize component dispersion. They also increase volume of a product while maintaining original or improving physical properties. Because of their consistent color, these oils are optimal with applications regarding the minimization of stains and discoloration. Since these oils are lower in viscosity for given volatility levels, in processing, less oil is necessary, potentially lowering manufacturing costs.

Top 5 Amazing Benefits of Mineral Oil

White mineral oil is an odorless and colorless liquid that is a highly refined product of the crude oil refining process.  White mineral oil is a key ingredient for various products used in the cosmetic industry, baby oil and medicinal purposes among others.  NF/USP quality is regulated by the FDA and ensures medicinal/food grade purity and safety.

Many people are not aware of the benefits of white mineral oil, which is the main focus of this article.

1. Makeup Remover

The alkanes in mineral oil are quite effective at cutting through makeup oils and chemical mixtures. Gently applying mineral oil to your skin will wipe away the makeup without hurting your skin.  It also keeps your eyebrows and eyelashes healthy and soft.

2. Scalp Conditioner

White mineral oil manufacturers have long been producing mineral oil that is geared towards the cosmetic industry. This is the oil that is used in solving various problems associated with the scalp. It plays a significant role in the treatment of dry skin, dandruff, scalp psoriasis, and cradle cap.

Users are advised to apply the oil on the scalp and leave it overnight for best results. The oil helps loosen dry scales while at the same time reducing inflammation. Repeating scalp treatment two or three times is highly recommended for better results.

3. Nourish Dry Skin

Dry skin is a major problem among many people in the United States and Europe. Some people experience skin dryness in summer while others get it in winter. White mineral oil helps people with drying skin to stay smooth and soft. Skin dryness is a major health concern that if untreated could lead to medical conditions such as psoriasis.

Mineral oil distributors in the United States have highlighted that the oil is an effective emollient, which forms an oily layer on the skin that traps water improving skin hydration.  This moisturizing of dry skin helps it to heal more quickly.

4. Decrease Fine Lines

Premature aging is another major problem that is affecting a considerable number of people around the world. Exposure to sun, frost, ice, and unfavorable climatic conditions has caused many people to appear older than they actually are. Fine lines and scales on the face are one of the characteristics of premature aging.

Although there are several products and medical therapies that have been highlighted as major solutions to premature aging, mineral oil 70 continues to be one of the best solutions to early aging. The long term use of white mineral oil helps in softening the outermost layer of the skin. You may treat dark patches and fine lines with NF/USP white oil as recommended by your doctor.

5. Cutting Board Restorer and Rust Protection

White oils are used extensively in health and beauty applications, however, it is important to highlight that mineral oils have multiple benefits across various industries.  They are also useful in the kitchen renewing wooden cutting boards and of course as rust protection to kitchen knives.

White mineral oil has NF/USP quality for direct food contact and is absorbed quickly into dry wood cutting boards replacing oils that have been washed away over time.

Mineral oil helps in forming a protective shield on metal implements such as garden tools, knives, and lawn equipment thus preventing rust.  Coating metal equipment with mineral oils will extend their lifespan.

All About White Mineral Oil: Features and Applications

Throughout the United States, countless industries rely on white mineral oil suppliers to provide the materials needed for final production. Whether you work in the industrial sector, have your own cosmetics line, or operate a food processing plant, white mineral oil suppliers will likely play an essential role in your operations. But what exactly is white mineral oil and why is it used? We’ll answer some of the most common questions base oil suppliers receive pertaining to this type of oil in today’s post.

What Exactly is White Mineral Oil?

White mineral oil is a tasteless, odorless, and colorless liquid that’s used in a wide array of applications. White mineral oils have different chemical makeups and are generally complex in structures, but typically include mixtures of paraffinic, napththenic, and acrylic saturated hydrocarbons. Renoil White Oils, for example, are a mixture of saturated paraffinic and napthenic hydrocarbons. In general, mineral oil will usually contain between 15 and 40 of these hydrocarbons. Because of its lack of distinctive physical properties, white mineral oil can easily be used as an additive in any number of ways without compromising the color, scent, or flavor of the final product. It’s often used as a lubricating element, but it’s also utilized as a coolant, as a sealant, and as a binder in different applications.

What Are the Features and Benefits of White Mineral Oil?

Generally speaking, white mineral oil density is 0.86 grams per millimeter which is lighter than water at 1.0. The kinematic viscosity at 40°C ranges from 10 to 280 cSt. Alternatively, in Saybolt Universal Seconds (SUS) viscosity range is 60 to 1500 SUS at 100°F. White mineral oils are insoluble in water and are virtually free of oxygen, nitrogen, and sulfur. Because of their high initial boiling point (420°C) and low flammability rating, these oils are not considered to be a fire risk.

One of the obvious benefits of white mineral oils is their versatility. They can be used in a wide range of applications (which we’ll discuss below) and can be added without compromising the quality of a product. Mineral oil has a high degree of purity, making them an attractive option for all kinds of products that require additional lubrication, sealing, binding, or other chemical additions but that cannot be changed by any ingredients that are added into the mix.

Another important advantage to highlight is their safety. White mineral oils are food grade, meaning that they meet standards outlined by the U.S. Food and Drug Administration and can be safely used in food and cosmetic production. In some cases, these oils can even receive kosher and halal certifications. Although all chemicals must be handled using the proper precautions, when mineral oil is utilized as directed, it is safe for use. As a bonus, it’s also non-comedogenic and will not support pathogenic bacterial growth.

How Are White Mineral Oils Used?

As we’ve mentioned, white mineral oils are extremely versatile and are safe for direct contact with food and skin. Therefore, they’re used in countless applications. These are just some of the ways white mineral oil can be used:

  • Food Processing
  • Pharmaceuticals
  • Cosmetics
  • Mechanics and Electronics
  • Automotive Applications
  • Fabric and Rubber Manufacturing
  • Metal Fabrication
  • Biotech and Laboratory Research

Whether you need a reliable dough divider agent and a way to keep food wrappings crisp in your factory or plan to develop a body lotion and a water-resistant makeup product as part of a new line, white mineral oil can be one of the most effective ways to accomplish your goals and to safeguard the quality of your product at the same time.

Now that you understand more about white mineral oil and how it’s typically used, you’ll be in a better position to make a decision pertaining to the products you need from your base oil suppliers.

5 Common Misconceptions About White Mineral Oil

When it comes to lubricants and oils, it’s important to have the right information to prevent unplanned equipment shutdowns and product contamination. And because safety and productivity are both vital in the pharmaceutical and food industries and many others, it’s crucial to eliminate common misconceptions.

That said, consider the following five myths surrounding white mineral oil so you can feel confident the next time you place an order:

  1. White mineral oil is the same as any other oil. No two oils are the same. You wouldn’t choose high viscosity oils when your machines need low viscosity oils, and you wouldn’t opt for mineral oils when you need to order synthetics. Each oil is uniquely formulated for its application and regulatory requirements. White mineral oil, in particular, is designed to be food-safe whereas other oils aren’t.
  2. You can use industrial oils in food processing. There’s a common misconception that it’s okay to use industrial lubricants depending on whether the application is above or below the line. But industrial lubricants are still capable of reaching the food and beverages even if it’s used on the gearbox below the conveyor belt. This can be dangerous because these industrial lubricants can include lithium, barium, and black graphite.
  3. Black or blue oil is better than white oil. The color of the oil you’re using isn’t a key factor in selecting the oil for an application. What you do want to pay attention to is the viscosity, base, and thickener in the oil.
  4. Food-grade oils don’t work as well as other oils. Food-grade oils can be formulated using synthetics, which enables them to work well in high temperatures without compromising safety.
  5. All products are compatible. Just because your oil is food-safe doesn’t mean it’s compatible with other products. Oils are fabricated with various thickeners and there’s never a guarantee that two will be compatible. Always exercise caution when changing oils. Mixing food-grade with non-food-grade oils can create contamination issues.

Where can I find a white mineral oil supplier?

Not all oils are the same and can’t be used for every application. Oils in concentrations ranging from 1-99% are found in skin creams, lotions, body and face cleansers, lipsticks, vaselines, baby oils, and more. This makes white mineral oils safe for food, pharmaceutical, and cosmetic production.

If you’re looking for white oil manufacturers for high viscosity oils or low viscosity oils, Renkert Oil is the place for you. To learn more about our variety of high viscosity oils and performance lubricants, contact Renkert Oil today.
