COLD PROCESS EMULSION

Cold Process Emulsification

Cold process emulsions are prepared from base raw materials preferably without any external heat—i.e., cold. In an ideal world, this process would simply involve premixing the oil and water phases separately, then bringing them together with an efficient mixing system. To successfully eliminate the requirement for heat in the process, all raw materials must be liquids or soluble within their respective phases at ambient temperature. In fact, any increase in temperature generated would only be the direct result of the mixing process. To some, the separate blending of emulsifiers and low melting of waxes and oils using heat could be considered part of this process; however, this author believes they cannot be considered part of a truly cold process.

Advantages of cold processing include reduced energy cost, manufacturing times and equipment costs; greater flexibility for formulation development; and the absence of deleterious effects on temperature and shear sensitive ingredients. Temperature and shear sensitive ingredients such as fragrances, active compounds, preservatives, etc., can be added to the relevant phase prior to forming the emulsion. Cold processing potentially allows the formulator to construct entire phases separately, and to simply bring them together with a suitable mixing system.

Cold process emulsion allows you to come with different beautiful formulas, especially for oily/acne prone skin.
