Clash of the Creams: Which Skin Moisturizer Prevents the Greatest Amount of Moisture Evaporation?

CSEF · 2016 Product Science (Biological) (Junior Division Only)

Will A. Myatt · Mitchell (W.E.) Middle School, Rancho Cordova, Sacramento County

Overview

Objectives/Goals The objective of my experiment was to find out which skin moisturizer prevented the greatest amount of moisture evaporation. Methods/Materials Petri Dishes, Gelatin, Skin Moisturizers, Scale, Ruler, Measuring Tools. I weighed and measured Petri dishes of gelatin and skin moisturizers over the course of one week. Results I applied one tablespoon of each moisturizer to each petri dish. I had three petri dishes for each moisturizer (+ 3 controls). I weighed and measured each dish every day at the same time to calculate the percentage of moisture loss. Conclusions/Discussion After finding the percentage of moisture loss for each moisturizer, I found that Coconut Oil prevented the greatest amount of moisture loss. This shows that a natural moisturizer has the power to be better than human created moisturizers.

Summary statement

After testing various moisturizers, I found that Coconut Oil was the best at preventing moisture evaporation.

Help received

My parents helped me on writing Excel formulas. The rest of the project was done myself.
