What Isoamyl Laurate does

Softens hair and makes it easier to comb
Adds slip so strands glide past each other
Leaves a light, non-greasy feel
Helps skin feel smooth and supple

Isoamyl Laurate is an ester, a type of ingredient made by joining a fatty acid with an alcohol. Here the fatty acid is lauric acid, a common fat found in coconut and palm kernel oils, and the alcohol is isoamyl alcohol. The result is a clear, lightweight oil.

Formulators use it in conditioners because it spreads easily and leaves hair smooth without a heavy coat. It helps reduce friction between strands, which makes wet hair easier to detangle. In skin care, it adds a soft, silky finish and helps other ingredients spread evenly across the skin.

Good for

Suits most hair and skin types, and anyone wanting softness without heaviness.

Frequently asked questions

Is Isoamyl Laurate safe for skin?

It is generally well tolerated and is used in many rinse-off and leave-in products. As with any ingredient, a small number of people may react, so a patch test on a new product is a sensible habit. If you have a known sensitivity, check the full ingredient list first.

Is Isoamyl Laurate the same as coconut oil?

No. Coconut oil is a blend of many fats. Isoamyl Laurate is a single, made ester. It uses lauric acid, a fatty acid also found in coconut oil, but the finished ingredient is lighter and spreads differently. Its job in a formula is more about slip and softness.
