1. Beaker 1 was held with crucible tongs just above the surface of the boiling water bath (a 400 mL beaker containing about 200 mL of tap water and a few boiling chips). 2. Beaker 2 was heated in the same way. 3. Into beaker 2, the contents of beaker 1 was slowly added while stirring constantly. After stirring for about 5 minutes, a homogeneous paste of the beauty cream was obtained. Beaker 1- in a 50 mL beaker place 4 g of lanolin, 5 mL of mineral oil, and 5 g of stearic acid. Beaker 2- in a 100 mL beaker place 25 mL of water and 1 mL of triethanolamine. 1. Give the chemical formula of the beauty cream in this experiment. Indicate which end of the beauty cream molecule is nonpolar and which end is polar. 1.
