Emollient
The term comes from the Latin “mollis,” which means to soften, make supple. In the field of dermatology and cosmetics, the word emollient refers to a set of phenomena aimed at making the superficial layers of the skin softer, smoother, and more supple.

Oily substances are the quintessential emollients: oils and fats of plant, animal, mineral, and synthetic origin (these are insoluble organic compounds, greasy to the touch) which, due to their chemical structure, have many applications in cosmetics. The more emollient a substance is, the greater the sensation of skin softness after direct application. The way this occurs is closely linked to the concept of spreading and the formation of an oil/fat film that determines the lubrication of the skin’s surface.
The greasiest emollients will spread on the skin with more difficulty and will have a more occlusive effect compared to less greasy substances. This is why creams are formulated by adding lipid-rich emollient agents for night creams (which promote occlusion), moderately greasy emollients for day creams, and more volatile emollients for lotions intended for application on large areas (legs, arms, etc.). It should also be noted that emollient ingredients can also have nourishing and moisturizing properties.
