Patients with < 10% TBSA burns can be resuscitated orally (unless the patient has an electrical injury or associated trauma). In the case of patients with burns 10-40% TBSA, secure a large-bore IV line; add a second line if transportation will take longer than 45 minutes.

Water is an ingredient that can dissolve soap. Water is a solvent and the the soap is the solute. Solutes are things that dissolve in solvents. I'm not sure what you're asking about an ingredient, but water makes all soap dissolve.
According to Newton, ethanol is added to liquid soaps to serve as a germicide. Ethanol is considered to be insoluble when mixed into a solid soap. Since water and oil are unable to mix, ethanol has the ability to dissolve on a partial level in water and oil. This process assists the reaction of fatty acid and sodium hydroxide to produce water, soap, salt and fatty acids. In essence, ethanol allows for the water and the oil to have better contact. The process of making soap has generally remained unchanged over the years, however, there are various stories as to how soap was originally created.
