What Lauroyl Lysine does

Binds pigment particles together
Helps powder adhere to skin
Adds a soft, silky feel

Lauroyl Lysine is made by joining lysine, a building block of protein, with lauric acid, a fatty acid that is usually sourced from coconut or palm kernel oil. The result is a fine, white powder.

Formulators use it mainly as a binder. In pressed eyeshadows, it helps pigment particles cling together so the product holds its shape in the compact. On the skin, it helps the powder adhere and spread evenly. It also adds a soft, silky feel, so powder products glide rather than feel chalky.

Good for

Well suited to pressed and loose powders, including eyeshadow, where it helps color stay put and feel smooth.

Frequently asked questions

Is Lauroyl Lysine safe for sensitive skin?

Lauroyl Lysine is generally well tolerated and is used in many powder and makeup products. Like any cosmetic ingredient, some people with sensitive skin may react to it, so patch testing a new product is a sensible habit.

Is Lauroyl Lysine the same as lysine?

No. Lysine is an amino acid on its own. Lauroyl Lysine is lysine with a lauric acid chain attached, which gives it a fatty, binding character that plain lysine lacks. It is a different ingredient with a different job.
