What’s in hand cream?

There are two main ways in which hand cream works to moisturise your skin. One is by containing ‘occlusive agents’ that form a barrier that traps water, and the second is by including ‘humectants’ that attract more water to your skin.

So what’s in a typical hand cream?

  • 80% Water

This gives the cream volume and dissolves some of the ingredients.

  • 3% Glycerine

A typical humectant used to draw water from the atmosphere, attracting water to your skin.

  • 5% Thickeners

These are long polymer molecules, like PEG (polyethylene glycol) or PAA (polyacrylic acid), which make the cream thicker and easier to apply to your skin.

  • 2.5% Emulsifier

To make oil and water mix (and humectants dissolve in water and occlusive agents dissolve in oil) glyceryl stearate or stearic acid is used.

  • 7% Fats and oils

Coconut oil, petroleum jelly or lanolin (a waxy substances secreted mostly by sheep) can be used as occlusive agents to stop water from escaping, by forming a barrier on your skin.

  • 2.5% preservatives and fragrance

Because you want it to smell and nice and last for a long time…
