Theory –

Cold cream is an emulsion in which the proportion of fatty and oily material predominates, although when it is applied to the skin a cooling effect is produced due to the slow evaporation of the water contained in the emulsion. Cold cream is an example of a Water-in-oil (W/O) emulsion.

In cold cream, the major portion is the oil phase. Simply, the cold cream is an oil-based semisolid preparation. Cold cream is also known as Unguentum or Ceratum Refrigerants. Generally, it contains mineral oil, beeswax, borax, and water [1]. It is a soothing and cleansing cosmetic typically of oily and heavy consistency, used to soothe and cleanse the skin. It can be classified as a form of cleansing cream.
