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.
1 Cup of water. 2 Teaspoons of Honey. 3 Teaspoons Grapeseed Oil. Cut the soap into shavings so that it dissolves easily. Place the shaving and other ingredients in an applicator or spray bottle. Add warm water to the mixture. Shake well until soap is fully dissolved and use as you would normal shampoo.
