Uniproma is promoting Ethyl Macadamiate, a plant-derived emollient made from macadamia oil, for silicone-free and reduced-silicone beauty products. In tests against crude macadamia oil from the same batch, the ester had lower viscosity, a lower contact angle and less blotting-paper residue; the company says it is available for formulation evaluation.
Uniproma is highlighting Ethyl Macadamiate, a plant-derived emollient made from macadamia oil, as an option for beauty brands developing silicone-free or reduced-silicone formulas. The company says comparative tests found the ester spread more readily and left less oily residue than crude macadamia oil from the same batch, addressing a sensory challenge for formulators replacing low-viscosity silicone oils.
Ethyl Macadamiate is produced through biocatalytic transesterification, a process that converts macadamia triglycerides into a lighter, lower-viscosity ester. Uniproma reports a surface tension of 21.9 mN/m, within the 19–22 mN/m range it associates with low-viscosity silicone oils. The reported value is below the 29.1 mN/m measured for the crude macadamia oil used in the comparison. The company says this property supports rapid spreading and smooth glide.
In the comparison with crude macadamia oil from the same batch, Ethyl Macadamiate measured 35.6 cps in viscosity, compared with 127.5 cps for the oil. Uniproma describes that result as 3.58 times lower viscosity. The ester also had a 40% lower contact angle, which the report links to faster, more even spreading, and left 67.1% less residue on blotting paper. The company interprets the residue result as evidence of a cleaner, less oily finish.
Uniproma says improved spreadability was observed from an addition level of 2% in meadowfoam and olive oil bases, with performance increasing at higher dosage levels. Compatibility screening under the company’s specified test conditions showed compatibility with 21 commonly used oils and emollients. The supplied report does not detail the individual test protocols or identify all the oils screened.
A Sensory Option for Silicone-Free Formulas
For product developers, the announcement addresses a practical formulation problem: removing silicone does not by itself reproduce the smooth glide, quick spread and refined finish associated with some low-viscosity silicone oils. An alternative emollient may help brands pursue silicone-free positioning while keeping a lighter feel, although the result will depend on the full formula and how the ingredient is used.
The reported figures give formulators physical measures to compare with crude macadamia oil, rather than relying only on broad sensory descriptions. Lower viscosity, a lower contact angle and less blotting-paper residue each relate to a different aspect of handling or finish. These measures can inform early evaluation, but they do not establish how a finished product will feel to consumers or perform across every formulation.
Uniproma lists possible uses including facial creams and lotions, sunscreens, hair oils and serums, along with facial oils and other anhydrous products. Those are potential applications identified by the company, not reported launches or independently confirmed product results. For brands, the ingredient’s relevance will depend on whether testing in a specific oil phase delivers the desired feel, stability and product performance.
From Macadamia Oil to Ester
The report frames Ethyl Macadamiate as a way to retain a plant-derived ingredient story while changing the sensory profile of the source oil. Crude macadamia oil had higher viscosity and surface tension in the company’s comparison. Processing it into an ester yielded a material with lower reported values on those measures, which Uniproma says can support a lighter feel and faster spread.
That distinction matters because ingredient origin and sensory performance answer different formulation questions. A plant-derived emollient can support a particular product positioning, while measurements such as viscosity and contact angle help developers assess how it behaves. The supplied report presents the comparisons as company testing; it does not provide independent replication or results against a named silicone ingredient.
Uniproma says compatibility screening may allow the ingredient to fit into a range of oil phases without a complete redesign. The report also notes that spreadability improvements appeared at 2% in meadowfoam and olive oil bases. That dosage observation is limited to those stated bases and does not establish an effective level for every product type or formula.
““The next generation of silicone-free formulation will be defined not only by the ingredients removed, but by how effectively sensory performance is reconstructed through thoughtful oil-phase design.””
— Uniproma
Questions Before Formulation Trials
The supplied report does not give test methods, sample sizes or independent validation for the comparative measurements. It also does not identify a specific silicone oil tested alongside Ethyl Macadamiate. The comparison described is with crude macadamia oil from the same batch, so the figures should not be read as a direct performance comparison with silicone ingredients.
Details are also missing on how the ester performs in finished products over time, including stability, compatibility across specific formulas and consumer sensory results. Uniproma’s screening found compatibility with 21 oils and emollients under its stated conditions, but the report does not name them or describe those conditions. The company’s potential application list does not confirm commercial launches or product-level outcomes.
Samples and Formulation Evaluation
Uniproma says samples, comparative test data and formulation guidance are available to developers considering the ingredient in silicone-free and reduced-silicone systems. The next practical step for interested formulators is to assess it in relevant bases and product formats, since the reported measurements do not predict every finished formula’s sensory profile.
No launch schedule, named customer adoption or further testing milestone is specified in the supplied report. Further details on protocols, the screened oils and performance in complete products would help developers judge how broadly the reported results apply. Until such information is provided, the announcement remains a company presentation of ingredient data, with application outcomes still dependent on formulation testing.
Key Questions
What is Ethyl Macadamiate?
Ethyl Macadamiate is a plant-derived emollient made by biocatalytic transesterification of macadamia triglycerides, according to Uniproma. The company describes it as a lighter, lower-viscosity ester than crude macadamia oil.
What did Uniproma’s comparison measure?
Against crude macadamia oil from the same batch, Uniproma reports lower viscosity, a lower contact angle and less blotting-paper residue for the ester. The supplied report does not include full test protocols or independent replication.
Which products could use the ingredient?
Uniproma names facial creams and lotions, sunscreens, hair oils and serums, as well as facial oils and other anhydrous products. These are potential applications; the report does not identify finished product launches.
Is it compatible with other oils?
The company says screening under specified conditions found compatibility with 21 commonly used oils and emollients. The report does not list those materials or provide enough detail to establish compatibility in every formula.
How can formulators evaluate it?
Uniproma says it can provide samples, formulation guidance and comparative data. The reported spreadability result at 2% applies to meadowfoam and olive oil bases; developers would need to assess performance in their own formulations.
