LAUROYL LYSINE
Lauroyl Lysine is a derivative of L-lysine joined to a lauroyl group, also called a dodecanoyl group. That connection gives the molecule one portion associated with a twelve-carbon fatty-acid chain and another associated with the amino acid lysine, so it is not the same as the lysine found in foods or supplements.
LAUROYL LYSINE: what it is
Lauroyl Lysine is a derivative of L-lysine joined to a lauroyl group, also called a dodecanoyl group. That connection gives the molecule one portion associated with a twelve-carbon fatty-acid chain and another associated with the amino acid lysine, so it is not the same as the lysine found in foods or supplements.
The technical name N6-lauroyl-L-lysine indicates that the lauroyl chain is attached to the nitrogen in L-lysine's side chain. This detail distinguishes Lauroyl Lysine from other lysine derivatives that may look similar on an ingredient list but have a different structure and may serve a different purpose in a formula.
LAUROYL LYSINE: what it does in cosmetics
In skin and hair cosmetics, Lauroyl Lysine is used for conditioning. In everyday terms, that use is intended to contribute to a more pleasant feel and to the appearance and touch a product leaves after application. It can also help adjust viscosity, meaning how fluid or how full-bodied a formula is.
A formulation study examined lauroyl lysine particles for stabilising an emulsion under laboratory conditions and found stability in the tested system. This helps explain its technical interest in formulations, but it does not by itself show that the ingredient treats skin, improves wrinkles, or produces a specific result on hair.
LAUROYL LYSINE: conditions and care
The Cosmetic Ingredient Review assessment covers current cosmetic uses and concentrations and concluded that these derivatives are safe when formulations are nonirritating.
