lotion
A lotion (pronounced either German [ loˈt͡si̯oːn ] or English [ ˈləuʃn̩ ]; from Latin lōtiō "washing, bath", to lavāre "washing, bathing") is an externally applied liquid aqueous or aqueous-alcoholic preparation with suspended or emulsified pharmaceutical active ingredients and excipients .
Lotions are used to cleanse, treat or care for the skin .
Liquid suspensions with 50% solids (zinc oxide, titanium dioxide), also known as lotions or shaking mixes (see graphic), are applied with a brush and have a slightly drying and secretion-absorbing effect.
A lotion or milk (e.g. sun milk) is often colloquially referred to as an oil-in-water emulsion to be used externally . This makes it very light and does not smear.
etymology
Lotions and ointments are very old. How old exactly cannot be determined.
When a bottle from the grave of Hatshepsut (1450 bC) was examined in 2011 , there was a kind of lotion in this bottle. It is believed that the pharaoh suffered from psoriasis and tried to get rid of it with the help of this lotion. She died because the lotion also contained tar. The lotion was her undoing and is one of the earliest deliveries of a lotion to this day.
