Emollients are substances which soften and soothe the skin. They
are used to correct dryness and scaling of the skin. They are a
key component in the manufacture of lipstick, lotions and other
cosmetic products. The terms "moisturizer" (something that adds
moisture) and "emollient" (something that softens) are sometimes
used interchangeably, as they describe different effects of
these agents on the skin. However, the term emollient is most
often used to describe single ingredients, whereas "moisturizer"
describes finished products. Mechanism of action Emollients have
three basic properties: - Occlusion - providing a layer of oil
on the surface of the skin to slow water loss and thus increase
the moisture content of the stratum corneum. - Humectant -
increasing the water-holding capacity of the stratum corneum. -
Lubrication - adding slip or glide across the skin. There is no
