Industrial manufacturing has long relied on petroleum-derived chemicals as processing aids, lubricants and functional additives. Today, manufacturers across the rubber, polymer and lubricant industries are increasingly exploring bio-based alternatives as they respond to evolving regulations, sustainability commitments and customer expectations.
These include palm-based derivatives which have a broad range of functions in industrial formulations, from supporting rubber processing to improving the performance of lubricants and polymers.
For formulators and procurement professionals, these are not new. Stearic acid, for example, has been used in rubber compounding for decades, while fatty acid esters are established components of lubricant formulations. What is changing is the growing focus on the performance, sourcing and sustainability characteristics of these ingredients.
This article explores bio-based palm oleochemicals applications in rubber, polymers and lubricants, and what buyers should consider when sourcing them.
What Are Bio-Based Oleochemicals?
Oleochemicals are chemicals derived from natural oils and fats. Common feedstocks include vegetable oils such as palm oil, palm kernel oil and coconut oil, as well as animal fats.
They include several major product families, including fatty acids, fatty alcohols, fatty acid esters, glycerol and methyl esters. Each has different properties and can be used across a wide range of industries, including home care, plastics, rubber and lubricants.
Palm oil and palm kernel oil are among the leading global feedstocks for commercial oleochemical production. Their availability and fatty acid composition make them important sources of the C16 and C18 fatty acids commonly used in industrial applications.
The versatility of such oleochemicals comes from their ability to be further processed into ingredients with different functional properties. This allows manufacturers to select specific oleochemical derivatives according to the requirements of their formulations.
Oleochemicals in the Rubber Industry
Rubber products such as tyres, seals, hoses, conveyor belts and other industrial components rely on carefully formulated mixtures of rubber, fillers, curing agents, processing aids and other additives. Oleochemicals have long played a role in these formulations.
One of the most established examples is stearic acid, which is widely used in rubber compounding. It supports the vulcanization process, in which rubber is cured to give it the strength, elasticity and durability required for its intended application.
Stearic acid also functions as a processing aid during rubber compounding. It can help reduce friction during mixing and processing, support the dispersion of fillers and other ingredients, and facilitate processing and release during manufacturing. These functions make stearic acid a versatile ingredient across a range of rubber applications.
Other oleochemical derivatives can also be used in rubber formulations. Certain fatty acid esters can be used as plasticisers or processing aids in specialised applications.
The specific oleochemical, grade and dosage depend on factors such as the type of rubber, formulation and desired product performance. For manufacturers, selecting the right grade is therefore an important part of formulation development.
Oleochemicals in Polymer Manufacturing
Oleochemicals can also support the processing and performance of polymers and plastics.
Fatty acid esters can be used as processing aids, lubricants, dispersants and release agents. Depending on the formulation, these ingredients can help improve processing efficiency, facilitate the movement of materials through manufacturing equipment, and support the release of finished products from moulds.
In polymer processing, relatively small quantities of additives can influence how a material behaves during manufacturing. The choice of additive therefore depends on the polymer system, processing conditions and the properties required in the finished product.
Oleochemical-based ingredients offer formulators another option when developing formulations that balance processing performance with sourcing and sustainability considerations.
Oleochemicals in Lubricant Formulations
Lubricants are another important application for oleochemical derivatives. Esters are widely used in lubricant formulations because their molecular structure gives them useful lubricating properties. Their polarity allows them to interact with metal surfaces, which can support lubrication where surfaces come into close contact.
Many bio-based lubricant formulations also offer a high viscosity index, meaning their viscosity can remain relatively stable across changes in temperature. This can be useful in applications exposed to varying operating conditions.
Oleochemical-derived esters can be used in a range of applications, including industrial lubricants, hydraulic fluids, metalworking fluids and environmentally sensitive applications where biodegradability is an important consideration.
Different ester chemistries provide different combinations of properties. Formulators can therefore select and modify ester-based ingredients according to requirements such as lubricity, oxidative stability, temperature performance and biodegradability.
As with rubber and polymer applications, the appropriate oleochemical depends on the formulation and end use. Technical support from an experienced supplier can help manufacturers identify the most suitable ingredient for their application.
The Sustainability Considerations of Bio-Based Oleochemicals
The sustainability case for oleochemicals is one reason they are receiving greater attention from manufacturers and procurement teams.
Renewable feedstocks
Unlike petrochemicals, which are derived from fossil resources, bio-based oleochemicals are produced from natural oils and fats. Plant-based feedstocks originate from biomass that forms part of the relatively short-term carbon cycle.
However, the sustainability performance of an oleochemical cannot be assessed by its feedstock alone. Factors such as agricultural practices, processing, transportation and supply chain management also matter. Musim Mas is a leading sustainable palm oil producer committed to zero emissions by 2050 under the SBTi framework.
Biodegradability
Some oleochemical-derived products, particularly certain ester-based formulations, can offer good biodegradability. This can be an important consideration for applications where lubricants or other industrial products may come into contact with the environment.
Responsible sourcing
For companies with sustainability commitments, the origin and traceability of raw materials are increasingly important. Certification systems such as the Roundtable on Sustainable Palm Oil (RSPO) and International Sustainability and Carbon Certification (ISCC) can provide mechanisms for verifying aspects of sustainable and traceable supply chains. Musim Mas is compliant with leading palm oil certification standards and schemes.
How to Choose Oleochemicals for Industrial Applications
Choosing an bio-based oleochemical is not simply a matter of selecting a bio-based alternative. The ingredient must meet the technical requirements of the application while also fitting the buyer’s sourcing and sustainability objectives. Other considerations can help guide the process such as:
- Technical fit
Different fatty acids, esters and other oleochemical derivatives provide different properties. Buyers should consider factors such as fatty acid composition, purity, physical form and other relevant specifications, as well as how the ingredient will interact with the wider formulation.
- Consistent supply
Reliable supply is important for manufacturers operating at scale. Buyers should consider the supplier’s manufacturing capabilities, raw material sourcing and ability to provide consistent product quality across batches. As a vertically integrated palm oil major, Musim Mas is committed to maintaining reliability through supply chain excellence.
- Technical support
Oleochemicals are used in diverse formulations, and the most suitable grade can vary depending on the application. Musim Mas provides technical guidance, product specifications and application support to help manufacturers evaluate and optimise their formulations.
