T. Joseph Lin, Ph.D.
A consulting chemical engineer and pioneering emulsion scientist, Dr. Lin served as Head of Research & Development at Max Factor, one of the world's most iconic cosmetic companies.
In 1976, he introduced the concept of Low Energy Emulsification (LEE) to the cosmetic industry — a breakthrough that reduced manufacturing energy consumption by 30–80% while simultaneously improving product quality. His work has been cited by researchers and manufacturers worldwide for nearly five decades.

03 — The Method
What is Low Energy
Emulsification?
LEE is a manufacturing philosophy that uses the internal thermodynamic properties of an emulsion system — rather than brute mechanical force — to create stable, fine-droplet emulsions.
Use energy only where needed
Instead of heating the entire batch, LEE targets thermal energy only to the pre-selected phase that requires it — the β phase — leaving the bulk of the external phase at room temperature.
Use energy only when needed
Energy is applied at the precise moment in the manufacturing sequence where it produces the most effect, rather than maintaining high temperatures throughout the entire process.
Use only the amount needed
By optimizing the ratio of heated to unheated phases, manufacturers can minimize the total thermal load while maintaining or exceeding conventional emulsion quality.
