WebJul 16, 2024 · Film-forming foam type. AFFF (aqueous film-forming foam) and FFFP (film-forming fluoroprotein) fire extinguishers are rated for use on both Class A and Class B fires. As the name implies, they discharge a foam material rather than a liquid or powder. They are not suitable for use in freezing temperatures. WebClassification based on solubility. The different globular proteins can be classified based on their solubility in different solvents, such as water, salt and alcohol (see: Gluten: definition, structure, properties, containing grains).

WebThis chapter focuses on the nature and scope of suitable nonaqueous solvents for inorganic chemistry. There are two considerations that influence the choice of suitable solvent systems: (1) the possibility of dissociating the solute into ions and (2) the possibility of setting up acid–base systems in which the solvent might participate.
WebTwo options are available when setting limits for Class 2 residual solvents. Option 1. The concentration limits in ppm stated in Table 2 are used. They were calculated using equation (1) below by assuming a product weight of 10 g administered daily.
