Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath , in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.
Subliming dry ice pellet, with white frost on the surface. Dry ice is the solid form of carbon dioxide.It is commonly used for temporary refrigeration as CO 2 does not have a liquid state at normal atmospheric pressure and sublimes directly from the solid state to the gas state.

Dry-ice blasting is nonabrasive, non-conductive, nonflammable, and non-toxic. Dry-ice blasting is an efficient [3] [verification needed] cleaning method. Dry ice is made of reclaimed carbon dioxide that is produced from other industrial processes, and is an approved media by the EPA, FDA and USDA. It also reduces or eliminates employee exposure ...
Ice blasting is a method of industrial cleaning that uses a continuous supply of compressed air to accelerate suspended ice particles to high speeds. The ice particles are ejected from a nozzle toward the surface to be cleaned. The ice particles impact the contaminant covering the surface, breaking it apart and knocking it off.

Anionic surfactants: branched alkylbenzenesulfonate, linear alkylbenzenesulfonate, and a soap. Surfactants are responsible for most of the cleaning performance in laundry detergent. They provide this by absorption and emulsification of soil into the water and also by reducing the water's surface tension to improve wetting.
