Students determine percent solids, compare viscosity, and make water-ethanol determinations. Since students use hand lotions from home, an excellent correlation can be made by comparing the lotions chemically to how they are advertised.
Includes: propylene glycol monostearate, oleic acid, mineral oil, cetyl alcohol, lanolin, glycerine, triethanolamine, weighing dishes, student data sheets, medicine cups, BB’s, vial of pH paper, instruction guide with suggestions for lab situations and with special needs students.
