Introduction

Chemistry Lab Report-6 Shampoo test Teacher?s Instruction: Investigate the Chemical Properties different shampoo brands and determine the best brand of shampoo manufacturers. Apparatus Required: Beaker Measuring cylinder Boiling tube pH meter Reagents Used: Shampoo Ink Distilled water Procedure: Test A (determination of pH): Take your 1% shampoo solution in a beaker and using the pH meter find the pH value of the shampoo. Information: Most shampoos are neutral or slightly acidic. Acidic solutions cause the cuticle of the hair to shrink and lay flatter on the shaft of the hair. Basic solutions cause the cuticle to swell and open up. Acidic solutions make the hair seem smoother. Basic solutions make their hair seem frizzier. ...read more.

Middle

Test D (Dirt dispersion): Put 2 drops of shampoo in a large test tube. Add 10ml of distilled water and then add 1 drop of ink. Then put a stopper at the mouth of the test tube and shale it well 10 times. Then estimate the amount of ink in the foam as (none, Light, Moderate, or heavy) Information: Shampoos that cause the ink to concentrate in the foam are considered poor quality. The dirt should stay in the water portion. Dirt that stays in the foam will be difficult to rinse away. It will deposit on the hair. Precautions and improvements Make sure you measure the volume of shampoo before mixing it with distilled water to form foam. ...read more.

Conclusion

conclusions of the best shampoo brand: Dove moisturizing is the best shampoo due to its best results during the test.Alberto VO5 is the worst shampoo due to its worst results during the test. Dove forms smaller bubbles, retains the amount of lather and also does not contain dirt in the foam rather than the liquid below. Therefore, Dove moisturizing shampoo passed all the tests. On the contrary, Alberto VO5 forms larger bubbles and disappears with time. It holds the dye on the foam and does not eliminate the dye to the liquid portion below. Therefore, VO5 is the worst shampoo that failed all tests. (Please note): The experiment was conducted with only limited amount of shampoo brands. Therefore the results pertain to only those involved in the experiment). ________________ | Page ...read more.
