In addition to the flavour defects initiated or influenced by damage to the fat globule membrane, such damage also results in a variety of physical defects in milk and especially in cream. The more important of these are oiling-off , cream plug and age thickening . 

A chlorine cylinder design includes three fuse plugs (which melt at 165° F or 74° C) in each end. The heat from steam reportedly melted the plugs and the chlorine escaped through 3/8-inch (0.9 cm) diameter orifices. (See Chapter 3 for details.) (A tragedy also occurred when a steam hose was used on an ice cream refrigeration unit in Chapter 4.)...

A simple deodorant consists of an antibacterial agent in a cream base. Antiperspirant ingredients ( aluminum salts ) such as aluminum chlorohydrate, activated aluminum chlorohydrates, and aluminum-zirconium-glycine (AZG) complexes work by forming superficial plugs in the sweat ducts, reducing the flow of perspiration. Antiperspirants are available in four product types cream, liquid, powder, or stick. They usually include aluminum salts, titanium dioxide, oxyquinoline sulfate, zirconium salt, alcohol, and antibacterial agents. Some liquid forms are propellant dispensed (aerosols). Waxes, soap, and humectants may be present in minor proportion in stick forms. Roll-on types may be added with...

Into the other limb of the H-vessel, a quantity of pure mercury is poured so as to cover the platinum wire and form a layer about i cm. deep, and on the top of this is spread a layer, 3 mm. deep, of mercurous sulphate paste. The latter is made by rubbing together in a mortar, mercurous sulphate and mercury together with a small quantity of cadmium sulphate crystals and sufficient of the saturated solution of cadmium sulphate to form a thin cream. The liquid is then filtered off through a plug of cotton-wool placed in the stem of a funnel, with the aid of a filter pump. The paste is again rubbed up with a further quantity of the cadmium sulphate solution, and again filtered. The process should be repeated a third time. The purpose of this is to remove any mercuric sulphate which may be present.
