As demand for silicone-free and reduced-silicone beauty products continues to grow, formulators face a practical challenge: removing silicones is relatively straightforward, but recreating their smooth glide, rapid spread and elegant finish is not.
Without the right emollient system, silicone-free formulations may feel heavy, greasy or slow to absorb. This can create a gap between a natural-positioned product concept and the refined sensory experience consumers increasingly expect.
Ethyl Macadamiate offers a plant-derived approach supported by measurable performance.
Transforming Macadamia Oil into a Lighter Ester
Ethyl Macadamiate is produced through biocatalytic transesterification, transforming macadamia triglycerides into a lighter, lower-viscosity ester.
This structural change influences several properties that consumers perceive during application, including viscosity, spreadability and residual oiliness.
Its surface tension reaches 21.9 mN/m, within the 19–22 mN/m range associated with low-viscosity silicone oils and below the 29.1 mN/m measured for crude macadamia oil.
This lower surface tension supports rapid spreading and smooth glide, helping Ethyl Macadamiate provide silicone-like sensory characteristics while maintaining a plant-derived positioning.
Lightweight Performance Supported by Data
In a comparative evaluation against crude macadamia oil from the same batch, Ethyl Macadamiate demonstrated clear differences across three sensory-related parameters：
● 3.58 times lower viscosity: 35.6 cps compared with 127.5 cps
● 40% lower contact angle: supporting faster and more even spreading
● 67.1% less blotting-paper residue: indicating a cleaner and less oily finish
Together, these results demonstrate how Ethyl Macadamiate can contribute to rapid glide, reduced drag and a lightweight after-feel without relying on traditional silicone oils.
Rather than replacing silicones through positioning alone, the ester provides measurable physical properties that help formulators rebuild key elements of the sensory experience.
Supporting Flexible Oil-Phase Design
Spreadability improvements were observed from an addition level of 2% in meadowfoam and olive oil bases, with performance increasing progressively as the dosage rose.
Compatibility screening also showed compatibility across 21 commonly used oils and emollients under the specified test conditions. This broad compatibility supports flexible integration into existing oil phases and allows formulators to refine sensory performance without completely redesigning the formulation system.
Ethyl Macadamiate can therefore support a range of applications, including:
● Lightweight facial creams and lotions
● Sunscreens requiring smooth and even application
● Silicone-free hair oils and serums
● Facial oils and other anhydrous systems
● Reduced-silicone formulations requiring lighter sensory performance
Rebuilding Sensory Elegance Without Silicones
Silicone-free formulation does not have to mean compromising on elegance.
The next generation of silicone-free products will be defined not simply by what is removed, but by how effectively glide, spreadability and after-feel are rebuilt through thoughtful oil-phase design.
By combining plant-derived positioning with low viscosity, rapid spread and reduced residue, Ethyl Macadamiate provides formulators with a versatile tool for creating lightweight, silky and refined beauty formulations.
Comparative test data, formulation guidance and samples are available for formulators evaluating Ethyl Macadamiate in silicone-free or reduced-silicone systems.
