Carnitine Fumarate, also known by its chemical name 1-Propanaminium, 3-carboxy-2-hydroxy-N,N,N-trimethyl-, (2R)-, (2E)-2-butenedioate (2:1), is a compound that has found its way into the world of cosmetics primarily for its skin conditioning properties. This ingredient is a combination of L-Carnitine, a naturally occurring amino acid derivative, and fumaric acid, an organic acid found in various plants and fungi.
The history of Carnitine Fumarate in cosmetics is relatively recent, stemming from its initial use in the medical and nutritional fields. L-Carnitine has long been recognized for its role in energy production within cells, particularly in the metabolism of fatty acids. Fumaric acid, on the other hand, has been used in various therapeutic applications, including the treatment of psoriasis. The fusion of these two compounds into Carnitine Fumarate leverages their individual benefits, making it a valuable addition to skincare formulations.
Carnitine Fumarate is typically synthesized through a chemical reaction that combines L-Carnitine and fumaric acid. This process involves the careful control of reaction conditions to ensure the correct stoichiometric balance and purity of the final product. The result is a stable compound that can be easily incorporated into various cosmetic products, from creams and lotions to serums and masks.
