Part of the mission statement of our company is to educate. In today’s world when there is so much fear of chemistry I love the opportunity to help educate youth about opportunities in chemistry. Yesterday I participated in a presentation for a GEMS group; Girls in Engineering, Math and Science. The day was sponsored by a local high school leadership group and invitations were sent to middle school girls. There were 4 presenters and the girls circulated through the 4 classrooms for presentations. It seemed like the main theme and interest was robotics so cosmetic chemistry was a little different – its nice to let girls know how chemistry applies to their everyday life.
We made bath fizzies and talked about the chemical reaction involved between the sodium bicarbonate (baking soda) and citric acid. In case you are interested, the equation is below:
NaHCO3 + C6H8O7 → CO2 + H2O + Na3C6H5O7
The reaction between an acid (citric acid) and a base (sodium bicarbonate) yields a salt and water; in this case trisodium citrate and water. In this particular reaction, one of the products is also carbon dioxide which is a gas released and is what produces the fizziness in the bath.
Here is the bath fizzy formula we used:
1 cup baking soda
1/3 cup citric acid
1.5 ounce kokum butter (melted)
0.5 ounce rice bran oil (infused with horehound)
6 ml fragrance oil
Melt butter, mix with other ingredients and mold into a muffin tin. Let set for awhile so the butter hardens.
Another important thing we talked about was how to pronounce ingredients in an attempt to discredit the misnomer that ‘if you can’t pronounce it then its toxic’. I want girls to be smart enough to expand their vocabulary rather than be intimidated by new words and assume things are toxic just because they’ve never heard of them. We went over the ingredient list for their bath truffles to make sure they could pronounce everything.
Sodium bicarbonate, Garcinia indica (Kokum) Butter, Citric Acid, Oryza Sativa (Rice Bran) Oil, Marrubium Vulgare (Horehound) Extract, Fragrance.
I ended up having some time left over, so next year I’ll talk more about what a cosmetic chemist does on a day to day basis. I hope I stimulated at least some interest in chemistry. Have you ever taught young students about what you do?
Thank you so much for talking the time out to educate this group of girls. I have always been fond of that group, there are so few woman in math and science. I am sure the girls loved their talk.
I bet they had a great time and learned a lot! Speaking to that age group is so impactful. I hope you get the opportunity again!
I love that you do this. I'm attempting something similar on the elementary school level. It's an after school program and we talk about skin care and chemistry and how it's important to be beautiful on the inside. At the end of each class we make something. Your blog is timely, as just this afternoon we made bath fizzies! I think the more we talk to and listen to young girls, the more confident they will feel about themselves.
I never liked chemistry in school. But if I had someone present it in terms of cosmetics I probably would have been hooked.
I imagine you made quite the impact on the girls! So many of us do run away from chemistry.
