Emulsifying creams do not contain water, but consist mainly of fatty components.

Night creams contain more fatty emulsions than daytime creams. For example, the basis of classical night cream before
included beeswax, mineral oil, borax, water. In modern fatty creams, mineral oil is replaced with vegetable or animal oils, and beeswax - synthetic or semi-synthetic waxes and high-molecular alcohols.
