Stories: Oleochemicals

“People want better products – but they also want safer, cleaner, and more responsible ingredients. That’s the challenge we help solve every day,” said Christopher Lee, Head of Sales and Marketing for Oleochemicals at GAR.

In today’s world of product development, every formulation is a balancing act. Chemists and R&D professionals are expected to deliver on performance, aesthetics, safety, and sustainability – all at once.

A common tool formulators turn to? Fatty esters.

Found in everything from face creams and food supplements to pharmaceuticals and high-performance lubricants, fatty esters play a vital role in shaping how products feel, function, and behave under pressure. But not all esters are created equal – and not every supplier prioritises traceability or renewable sourcing.

Learn what fatty esters are, how they’re made, and where they’re used – especially for formulators seeking ingredients that are both high-performing and sustainable.

What on earth are fatty esters?

A fatty ester is the product of a simple but impactful chemical reaction:

This reaction transforms the original fatty acid into a compound with entirely different properties. Think of it like customising the ingredient to behave better – absorbing better, feeling lighter, or improving stability in a formulation.

How do they compare?

Fatty esters sit alongside fatty acids and fatty alcohols as part of a larger ingredient toolkit. Each plays a vital role depending on the product’s function, feel, and end-use.

Rather than replacing fatty acids or alcohols, esters complement them. This gives formulators greater flexibility to meet sensory, stability and sustainability needs.

GAR produces all three ingredient types derived from palm – fatty acids, fatty alcohols, and fatty esters – allowing our customers to select the right building blocks for their formulation.

From nature to innovation: How fatty esters are made

Every ester starts with a simple origin: nature.

At GAR, we source our fatty esters from responsibly grown palm oil – a renewable raw material that offers consistency, performance, and traceability.

How do we go from palm fruit to silky emollient in your hand cream or the lubricant keeping machinery running smoothly? We break it down for you.

Fatty esters can also be made synthetically from petroleum. While some components like alcohols are still derived from petrochemical sources, businesses are increasingly turning to bio-based fatty acid inputs. In ester production, fatty acids make up the bulk of the material required, far more than the alcohol portion. This means the choice of fatty acid feedstock is especially important. Here’s why bio-based inputs are gaining ground:

Inside the molecule: Meet our fatty esters range

No two esters are quite the same – and that’s the point. The structure of each fatty ester determines how it behaves: some glide smoothly on skin, some resist heat and pressure. Others carry nutrients where they’re needed most.

At GAR, we’ve developed a range of palm-based esters tailored for real-world performance across nutrition, personal care, pharmaceuticals, and industrial use. Each line is engineered for a specific function, but all share the same foundation: high-quality, traceable raw materials and a commitment to safer, smarter chemistry.

Expert take: What makes a great fatty ester

We spoke with Christopher Lee, our Head of Sales and Marketing for Oleochemicals to talk about what makes a high-performing fatty ester – and why customers are getting more curious about what’s behind their ingredients.

Q: What are the most common things customers ask about fatty esters?

Christopher: Performance and safety always top the list. For personal care, they want to know: “Will it feel light, will it absorb quickly, will it clog pores?” In food, it’s all about digestibility and compliance. In industrial applications, it’s thermal stability and oxidation resistance. What surprises many is how versatile esters can be across these different contexts when designed right.

Q: What trends are you seeing in fatty ester development today?

Christopher: There’s a clear move towards multi-functional esters. Customers want ingredients that offer more than one benefit – like softness and barrier repair in skincare, or flow enhancement and biodegradability in lubricants. There’s also strong interest in plant-based and palm-derived alternatives to synthetic esters, especially in markets prioritising clean labels and sustainability.

Q: What excites you most about the future of fatty esters?

Christopher: Their versatility. We’re only scratching the surface of what esters can do. With the right innovation, they can bridge the gap between performance and sustainability across so many sectors. From bio-based solvents and skincare, fatty esters are going to play a huge role in how we rethink ingredients – not just for what they do, but how they’re made.
