Cold Cream: Uses, Formulation, Preparation, Tests

Cold cream is a water in oil (W/O) emulsion, Also, it is known as Fatty Cream according to European Pharmacopoeia. Outcomes of this article: Uses of Cold Cream, Formulation of Cold Cream, Preparation of Cold Cream, Tests of Cold Cream, History and Ideal properties of cold cream.   Before the 1st century, many druggists would compound the rosewater cream and keep it fresh on ice, to make it cold as a skin cream. Cold cream was originally described as the Latin word “refrigeran” meaning “making cold” because when applied, the water evaporates and creates a cooling sensation [1].  You may also read: Difference between Ointment, Cream, Paste, Gel, Lotion, and Jelly. 

What Is Cold Cream

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 [3]. 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 Refrigerans [2]. 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. Cream vs Ointment 

According to European Pharmacopoeia, cold cream is known as Fatty Cream.

Uses of cold cream

Uses of cold cream depend on the ingredients of a cream which means functional ingredients define the uses of cold cream. The main uses of cold cream are as follows: 

  1. Medicated cold cream is mainly used as a topical pharmaceutical dosage form for the treatment of skin.
  2. Helps to maintain the skin’s moisture balance and avoid rough skin conditions. It is one of the primary uses of cold cream (non-medicated).
  3. As cleansing preparation to remove make-up.
  4. To provide an emollient effect.
  5. To provide an oily protective layer on the skin.
  6. Also, provide a chemical barrier as with sunblock ingredients.
  7.  As a carrier for drug substances such as diflucortolone valerate in medicated cream.
  8. To remove oil-soluble impurities from the skin.

 Uses of cold cream are less than vanishing cream (oil in water emulsion) as topical pharmaceutical dosage form.

History of Cold Cream Preparation

Cold cream was first invented by Galen, a famous Greek physician-pharmacist in the Roman Empire (who practiced in Rome) of the 1st Century AD. The Galen formula of cold cream has changed but little in proportions or method of preparation throughout many centuries [1].

Formulation and Preparation of Cold Cream

Raw materials and Apparatus

Raw materials as per formula. Cold creams may be formulated with oils, both or either mineral oil and vegetable oil, as well as fatty alcohols, fatty acids, and fatty esters, emulsifying agents, preservatives, and purified water. There should be four main ingredients as follow:

Apparatus required laboratory-scale production as follows:

  • Measuring Cylinder,
  • Beaker,
  • Stirrer/ Glass rod,
  • Thermometer,
  • Water bath.

Why cold cream is called cold cream?

The name “cold cream” derives from the cooling feeling of the cream, when applied the water evaporates and creates a cooling sensation. Besides, in cold cream, the major portion is the oil phase thus cold cream is used especially in cold temperatures or the winter season. On the other hand, vanishing cream is used for summer or hot environments because vanishing cream contains a large portion of the aqueous phase.

Ideal characteristics of cold cream

  1. It should not normally be diluted.
  2. The pH of the cold cream must be optimum from 4.6–6.0
  3. Its consistency should be optimum so that it can be easily put out from the container and apply easily.
  4. Should give a cooling effect on the skin after external application.
  5. It must provide a thin waxy protective layer on the skin to protect the water evaporation from the skin surface.
  6. Should give a faster emollient effect, so that very dry skin can swell up and become soft within a short time.
  7. Less greasy than ointment.
  8. Generally, creams are white to off-white color but may have different colors such as yellow (Nystatin Cream USP).
  9. Easily spread on the skin.
  10. Free from gritty particles.
  11. It should be nontoxic and nonirritant.
  12. Attractive in appearance.
  13. It should be physically and chemically stable throughout its shelf life.
  14. The excipients should be compatible with each other.
  15. It should be more easily washed off using water.
  16. Should be sterile. If any microbial growth is found then stop the use of cold cream.

Sterility, Storage and Labeling information

It should be sterile, it complies with the test for sterility.

Storage

It should not be permitted to freeze.

Labeling information

The label information should contain:

  • Manufacture and expiration date
  • Conditions under which it should be stored,
  • Where applicable,
  • Name of any added antimicrobial preservative.
