Ozokerite: Petroleum-derived ingredient in cosmetics
Ozokerite is a waxy mineral extracted from underground hydrocarbon-rich deposits. It is a petroleum derivative composed mainly of paraffins and microcrystalline waxes, which give it a firm and malleable texture. Its use has spread across various industries, from cosmetics to the manufacturing of industrial products, thanks to its waterproofing and emollient properties.
In this article, we will explore in detail what ozokerite is, its characteristics, how it is obtained, its main applications, and its benefits in different sectors.
What is Ozokerite?
Ozokerite is a brown, yellow, or black mineral wax found in nature in underground petroleum deposits. Its name comes from the Greek "ozein" (to smell) and "keros" (wax), referring to its origin and characteristics.
This wax is mainly composed of saturated hydrocarbons, similar to those found in paraffin, but with a more complex structure that gives it greater stability and resistance.
After its extraction, ozokerite undergoes a refining process to remove impurities and obtain a clearer, purer wax, used in various industrial and cosmetic applications.
Chemical Composition of Ozokerite
Ozokerite is a complex mixture of long-chain saturated hydrocarbons, predominantly from the paraffin and microparaffin family. Its composition varies according to its origin, but it generally contains:
- Solid and waxy paraffins
- Microcrystalline waxes
- Isomeric and aliphatic hydrocarbons
- Small amounts of aromatic compounds
This composition gives it its unique texture, water resistance, and ability to form protective films on various surfaces.
Physical Properties of Ozokerite
The properties of ozokerite depend on its degree of purity and refinement, but in general, it presents the following characteristics:
| Property | Description |
|---|---|
| Appearance | Solid wax, brown to yellowish |
| Odor | Weak, characteristic of hydrocarbons |
| Melting point | 60 - 90°C, depending on refinement |
| Solubility | Insoluble in water, soluble in oils and organic solvents |
| Texture | Flexible, malleable, and moisture-resistant |
How is Ozokerite Obtained?
1. Extraction
Ozokerite is extracted from underground deposits located in petroleum-rich regions. Its extraction is carried out through mines or by drilling into geological formations where it has accumulated naturally.
2. Refining and Purification
Once extracted, ozokerite contains impurities such as clays and other hydrocarbons. To make it suitable for use, it undergoes:
- Filtration to remove solid particles
- Distillation and hot pressing to separate purer fractions
- Treatment with solvents and bleaching agents to improve its color and remove residues
This process allows for the obtainment of different grades of ozokerite, from crude forms to highly refined waxes.
Uses of Ozokerite: petroleum derivatives in everyday life
The versatility of ozokerite allows its use in multiple industries, notably in cosmetics, pharmaceuticals, and manufacturing.
1. Cosmetic Industry
One of the main uses of ozokerite is in the manufacturing of cosmetic products, where it is used as a thickening agent and texture stabilizer. It is found in:
- Lipsticks and lip balms: Provides firmness and improves product adhesion.
- Mascara: Adds volume and hold.
- Creams and lotions: Acts as an emollient and skin protectant.
- Deodorant sticks: Helps solidify the formulation and improve application.
2. Pharmaceutical Industry
In the medical and pharmaceutical sector, ozokerite is used in:
- Ointments and salves: To thicken and stabilize formulations.
- Capsule coating: As a protective barrier.
- Bases for therapeutic creams: Improves texture and active ingredient absorption.
3. Candle and Wax Industry
It is used in the manufacture of long-burning candles, as its high melting point allows for more controlled combustion. It is also used in waxes for furniture, floors, and automobiles, providing shine and protection against moisture.
4. Industrial Applications
In industry, ozokerite has various applications, including:
- Machine lubrication
- Electrical insulation in cables and electronic components
- Production of waxed paper and waterproof coatings
Ozokerite in Natural Cosmetics
Many brands include this wax in their products and then claim it's natural because it's extracted from the earth. But as we mentioned earlier, this is a petroleum derivative, and therefore neither natural nor a renewable or sustainable raw material.
Is Ozokerite Safe?
Refined ozokerite is safe for cosmetic and pharmaceutical use, as it complies with sanitary regulations that ensure the elimination of impurities. However, its crude version may contain potentially irritating hydrocarbons.
In the cosmetic industry, it is approved by regulatory bodies such as the FDA and the EU, provided it is used in safe concentrations.
Differences between Ozokerite, Microcrystalline Wax, and Paraffin
Although ozokerite, microcrystalline wax, and paraffin are petroleum derivatives, they present key differences:
| Characteristic | Ozokerite | Microcrystalline Wax | Paraffin |
|---|---|---|---|
| Origin | Extracted from mines and petroleum | Refined from petroleum | Refined from petroleum |
| Texture | Hard and firm | Soft and flexible | Hard and brittle |
| Melting point | 60-90°C | 60-80°C | 40-70°C |
| Common Uses | Cosmetics, candles, coatings | Cosmetics, pharmaceuticals | Candles, waterproofing |
Natural Alternatives to Ozokerite
At Maxalli, we opt for natural, ecological, and botanically-sourced options, such as rice bran wax, carnauba, candelilla, cocoa butter, and hydrogenated vegetable oils.
Conclusion
Ozokerite is a mineral wax derived from petroleum, used in various industries due to its unique properties. Its ability to provide structure, stability, and moisture resistance makes it invaluable in cosmetics, pharmaceuticals, and manufacturing.
