Ozokerite and Paraffin Application: Properties, Deposits, and Therapeutic Uses
libre
Ozokerite is a naturally occurring mineral wax whose name means "smelling of wax," from the Greek roots ozo ("I smell") and keros ("wax"). It earned this name because, after appropriate processing, it resembles beeswax in appearance. Today ozokerite is valued both as a medicinal wax and as a versatile ingredient in cosmetics and industry.
What is ozokerite: definition and origin of the name
Ozokerite is a paraffin-type mineral wax formed in the earth's crust, closely associated with deposits of paraffinic petroleum. It occurs in colors ranging from pale yellow through green to dark brown, and once refined it becomes a firm, wax-like solid used in therapeutic, cosmetic, and technical applications.
Etymology of the term "ozokerite"
The word "ozokerite" is built from two Greek elements — ozo, meaning "I smell," and keros, meaning "wax" — a reference to the wax's characteristic odor and its resemblance to beeswax after purification. The mineral is also spelled "ozocerite" in English-language literature.
Paraffin ozokerite: what the name means
The phrase "paraffin ozokerite" reflects the close chemical kinship between ozokerite and paraffin wax. Both are hydrocarbon waxes, and ozokerite is frequently obtained during the processing of paraffinic crude and its by-products. Calling it "paraffin ozokerite" underscores that the material is a mineral hydrocarbon wax rather than an animal or plant wax, even though its refined appearance mimics beeswax.
Chemical composition of ozokerite
Ozokerite is a mixture of solid saturated hydrocarbons — predominantly high-molecular-weight paraffins and cycloparaffins — together with small amounts of resins, mineral oils, and mechanical impurities in the crude form. This hydrocarbon makeup is what links it geologically to paraffinic petroleum deposits and gives it its wax-like consistency.
Chemical properties of ozokerite
Ozokerite is chemically stable, hydrophobic, and inert toward most reagents at ordinary temperatures. It is insoluble in water but soluble in petroleum solvents, benzene, chloroform, and hot mineral oils, which makes it compatible with oil-phase cosmetic and industrial formulations. Its melting point falls in the range of roughly 60–80 °C, and its high heat capacity combined with low thermal conductivity is precisely what makes it effective for heat-retaining therapeutic applications.
Color variations and their dependence on composition
The color of ozokerite depends on its content of resins and residual oils. Purer grades tend toward light yellow, while higher resin and impurity content shifts the wax toward green, brown, and near-black shades. Refining removes mechanical impurities and part of the lighter oil fractions, lightening the color and raising the purity grade suitable for medical and cosmetic use.
INCI naming and classification of ozokerite
Under the International Nomenclature of Cosmetic Ingredients (INCI), the ingredient is listed simply as "Ozokerite," and the closely related refined grade is often marketed as "Ozokerite Wax." Its CAS registry number is 12198-93-5. In cosmetic classification it functions as a viscosity-controlling and structuring agent — a mineral wax used to thicken and stabilize oil phases. This standardized INCI naming lets formulators identify the same material consistently across suppliers.
Deposits and geography of ozokerite mining
Industrially significant ozokerite deposits are concentrated in a small number of regions, historically centered on the Carpathian oil belt and Central Asia. The quality and yield of ozokerite vary sharply between deposits, which is why only a few have ever supported commercial mining.
The Boryslav deposit
The deposit at Boryslav, in Galicia (western Ukraine, in the Carpathian region), has been known since ancient times and ranks first for both the quality and the quantity of ozokerite extracted. Historically, mining there was organized by companies such as the Boryslaw Actien Gesellschaft, financed in part through institutions like the Galizische Kreditbank, which built the infrastructure needed to work the ozokerite shafts.
Deposits in other countries
Ozokerite is also found on Cheleken Island (Cheleken Peninsula) in Central Asia, near the Shor-Su area, and in other countries including the USA — notably in Utah — as well as France and Spain. Outside the Carpathian belt, however, reserves are generally small and the deposits lack industrial significance. The British petroleum chemist Boverton Redwood documented several of these occurrences in early technical surveys of mineral waxes.
Historical decline in mining
Ozokerite mining has fallen dramatically from its 19th-century peak. As petroleum refining expanded, cheaper petroleum-derived waxes displaced natural ozokerite, and the labor-intensive shaft mining of ore that contains only up to about 2.5% ozokerite became uneconomical. Most modern medical ozokerite is now recovered from petroleum-industry residues rather than from freshly mined ore, and dedicated ozokerite mines have largely closed.
Production and extraction of ozokerite
Ozokerite is produced by processing ozokerite-bearing ore mined in shafts, and the method chosen depends on the intended use. The ore is transported to an extraction plant where the ozokerite is separated; because the ore holds only up to 2.5% ozokerite, efficient purification is essential.
The water-boiling method of ozokerite production
For medical purposes the solvent-extraction method is unsuitable, because it strips away some of the wax's biological properties. Instead, ozokerite is obtained by boiling in water, a process that relies on the difference in specific gravity between water and ozokerite and on the wax's relatively low melting point of 60–80 °C. The steps are:
- Ore is loaded into an iron cauldron, covered with water, and boiled for 35–50 minutes.
- The molten ozokerite floats to the surface because it is lighter than water, and is then skimmed off and poured into containers.
- This first product still contains water and mechanical impurities and is known as the crude "millet" fraction.
- It is then transferred to a special wax-melting cauldron and boiled without added water at 110–120 °C, driving off the water and part of the light fractions.
- Remaining impurities settle to the bottom; the dehydrated ozokerite is poured into molds where it cools.
The result is raw ozokerite, which is approved for use in medical practice.
Modern technology for producing medical ozokerite
Medical ozokerite today is obtained by extracting the wax from the residues of the oil-extraction and oil-refining industries, as well as from vein wax mined in ozokerite shafts. The updated process runs in two stages:
- Raw-material preparation. Paraffinic "plug" material is loaded into a cold cauldron with water and heated to about 100 °C. Gases and light petroleum fractions are released, the semi-finished ozokerite floats to the surface and is collected, the residual water is drained, and mechanical impurities are removed. Vein wax is boiled and cleaned separately in the same way.
- Final-product manufacture. The semi-finished materials — vein wax, paraffinic plug, and petrolatum — are loaded into a cauldron, melted, mixed, and pumped at 100–110 °C into the finished-product vessel. After cooling to 75 °C the ozokerite is poured into molds, where it hardens; the demolded blocks are wrapped in paper and shipped to the consumer.
Distillation products and derivatives of ozokerite
Refining and distilling ozokerite yields a family of derived waxes and fractions. Removing the darker resins and lighter oils separates high-melting, harder waxes from softer petrolatum-like fractions. The most commercially important derivative is ceresine, a refined mineral wax produced directly from ozokerite, alongside various grades of purified mineral wax used in candles, polishes, and technical coatings.
Ceresine production and its applications
Ceresine is manufactured by refining crude ozokerite — typically through treatment with sulfuric acid and filtration through absorbent earths — to produce a clean, hard, high-melting white or yellow wax. Ceresine is used as a substitute for beeswax and paraffin in candles, polishes, waxed paper, electrical insulation, and cosmetics, where its firmness and elevated melting point help structure and stiffen formulations.
Beneficial properties and functional characteristics of ozokerite
Ozokerite is prized for a combination of high heat capacity, very low thermal conductivity, and a soft, plastic consistency when warmed. These traits let it hold and release heat slowly, mold intimately to surfaces, and form stable, water-repellent structures. Its main functional benefits include:
- Excellent heat retention, making it effective for prolonged thermal therapy.
- Water resistance and chemical inertness, giving formulations stability and a barrier effect.
- Thickening and structuring power in oil phases, raising viscosity and melting point.
- Plasticity that lets it be shaped, applied, and remolded easily.
Applications of ozokerite
Ozokerite is used across medicine, cosmetics, and industry, drawing on its heat-holding and structuring properties. The same physical characteristics that make it a therapeutic heat carrier also make it a valuable formulation wax and a durable industrial material.
Treatment with ozokerite in medical practice
In medicine, ozokerite is applied as a heat carrier in thermotherapy: warmed to a tolerable temperature and applied to the skin, it delivers a slow, deep, and sustained release of heat used to relieve pain, reduce inflammation, and support recovery in a range of conditions. Its low thermal conductivity means it can be applied hotter than water at the same temperature without burning, which is central to its therapeutic value.
Use in cosmetics and personal-care products
Ozokerite serves as a structuring and viscosity-controlling wax in beauty and personal-care formulations, where it thickens oil phases, stabilizes emulsions, and hardens anhydrous sticks. Typical use levels range from around 3% to 15% depending on the desired firmness, and it is incorporated by melting it into the oil phase. It is commonly found in lipsticks, glosses, creams, and solid deodorants supplied by ingredient specialists such as MakingCosmetics Inc.
Examples of cosmetic formulas with ozokerite
Ozokerite appears as a structuring wax in many finished-product recipes. Representative examples include:
- Lipstick with Red 7 — ozokerite firms the stick and improves payoff.
- Strawberry Gloss Lipstick — the wax adds body and hold to a glossy formula.
- Frosting Cream — ozokerite thickens and stabilizes the cream texture.
- Coconut Charcoal Deodorant — the wax hardens the anhydrous stick base.
Industrial applications: insulation and other uses
Ozokerite and its derivatives have long served as electrical insulators and moisture barriers. Refined ozokerite wax was used to insulate cables — the historic insulating material Okonite took its name from ozokerite — and the wax was also applied as a waterproofing compound. In the shoe trade a wax blend known as heel-ball, containing ozokerite, was used to finish and polish the edges and soles of boots, illustrating its role as a durable, water-repellent coating material.
Commercial use of ozokerite
Commercially, ozokerite is sold as both raw wax and refined grades, with pricing and bulk-ordering options that vary by purity grade and quantity. Buyers typically request product documentation and certifications — including CAS 12198-93-5 identification and INCI listing — from suppliers, and larger formulators source bulk quantities directly. Cosmetic-grade Ozokerite Wax specifications commonly cover melting range, color, and purity, and reputable suppliers publish this data with reference numbers on their product pages.
Sustainability and ethical aspects
Ozokerite raises distinct sustainability and ethics questions because it is a mined mineral wax rather than a renewable plant material, yet it is frequently marketed with GMO-free and cruelty-free assurances. Understanding these claims helps formulators position ozokerite responsibly against alternative waxes.
GMO-free and sustainable production
Because ozokerite is a mineral hydrocarbon wax and contains no biological or agricultural feedstock, it is inherently GMO-free, and suppliers routinely document this. Sustainability considerations center instead on the finite nature of ozokerite deposits and the energy used in refining; recovering ozokerite from petroleum-industry residues rather than fresh ore is one way the supply chain reduces new mining.
Absence of animal testing and vegan certification
Ozokerite is a mineral wax that contains no animal-derived components, so it is commonly certified as vegan, and reputable suppliers state that neither the ingredient nor its processing involves animal testing. This makes it a frequent plant-free, animal-free substitute for beeswax in vegan cosmetic formulations.
Ozokerite and competition from petroleum-based products
Ozokerite competes directly with cheaper petroleum-derived waxes such as paraffin and microcrystalline wax, which offer similar structuring performance at lower cost. This competition, combined with the labor intensity of mining low-yield ore, is the main reason natural ozokerite production has declined and why much of the ozokerite on the market now originates as a refined by-product of the petroleum industry.
