LOTION By: Olga Prots

Q UESTION Which type of lotion will keep hands moisturized the longest?

H YPOTHESIS As we put the three different type of lotions(Fresh water-Cucumber, Pink and Miracle Forever by Lancôme) and test which one will keep hands moisturized the longest on a 13 year old then the Cucumber-rain will last longer because it is a lot thicker than the other lotions

B ACKGROUND I NFO Lotion was invented a long-long time ago, even when people opened the Ancient Egyptians tombs they had small jars of animal fat and olive oil substances which spices were added to. In the Biblical times it says that it was a luxury to anoint your feet with oil and massage them with other oils. In the 15 th century people started adding oils that smelled good to the other oils. Then people started adding plant juice to their lotions. And that’s how now we have so many different types of lotions. Usually lotions improve each year. Lotion is mostly used to heal dry skin or broken skin. There are different types of lotions. Most lotion has oils in it. Different ages use different types of lotions. Like for example Johnson's makes lotion specifically for little babies and small children. Other lotion is not even allowed for the use of children. Water makes up the biggest percentage in lotion. You can make a moisturizing lotion with only three ingredients; all you have to have is ¼ cup of olive oil, 1 ¼ cup of water, and ¼ cup of emulsifying wax. Lotion is made pretty easily. That’s why you can buy them really cheep. Most lotions have different ingredients and most of them smell differently. Better companies make lotion that’s more expensive. Most lotions are made from these ingredients; purified spring water, sesame oil, vegetable glycerin, Vitamin E and sodium tortberate. Lotion could be not just in bottles, but also in tissues. Oils also fall into the category of lotion because most lotion that is made has plant or flower oil in it. Lotion is helpful in some occasions and in some not. For example it can heal dry skin and can cure broken skin, but some people have allergic reactions to lotion.

P ROCEDURE See Diagram. Set up. Put lotion #1 (1/4 of a teaspoon) on hands of the 13 year old tester. Let the tester do everything they do normally but try their hands every 15 minutes to see if they still are moisturized Repeat steps 1-2 three times for lotion #2 and #3 Record the time it took each lotion to moisturize your skin StepsDiagram Lotion #1- Freshwater-Cucumber by: Bath & Body Works Lotion #2- Pink by Victoria’s Secret Lotion #3- Miracle Forever- by Lancôme Paris And a 13 year old student to test the different lotions

C ONCLUSION I thought that if I tested the three different lotions on the 13 year old then the freshwater- cucumber one will last longer because it is thicker. My results showed that the Freshwater- cucumber lotion did keep the hands moisturized the longest. I can prove this because the highest average was from the Freshwater-cucumber lotion and it was 2 hours and 15 minutes. The lowest average was from the Lancôme lotion and it was 20 minutes. This supports my original hypothesis. Therefore if we test which brand of lotion will keep hands moisturized the longest it would be the Freshwater-cucumber one from Bath & Body Works.

A BSTRACT The purpose why I did this project was because it seemed very easy to do. I believed that the Freshwater-cucumber lotion would keep hands moisturized the longest At the end of my experiment I found out that my prediction was correct First of all I would change my topic and do something that wouldn’t involve testing so long, because when I was testing the 13 year old we had to look every 15 minutes and the freshwater-cucumber lotion lasted 2 hours and 30 minutes for the longest so we had to test for a long time. Next time if I do a science experiment I am not going to use people in it, because the first person that we tested had an allergic reaction to the Pink lotion. We didn’t know this. This was a challenging experiment for me. The most important things I learned while doing this project was to be very accurate. Also I learned a lot from the background information
