Brittney Elko: Chemical Engineer

  • Name: Brittney Elko

  • Education: B.S. Engineering Science, focus in Chemical Engineering, Trinity University, TX
  • Target Audience: Middle School

With all the germs and bacteria out there, what would a world without cleaning products look like? Chlorine bleach, formulated by chemical engineers like Brittney Elko, is one of the only household cleaners regulated by the U.S. Environmental Protection Agency (EPA), which means that it's been tested and shown to kill harmful germs and bacteria. Read on to learn why a job in the household product industry might be the job for you!

What is your job?

I am a Product Development Scientist for Clorox, a company that develops and produces household products. I workimage in the cleaning and homecare division to chemically engineer products on the market like Formula 409, Pine-sol, Tilex and bleach products. Most of my work pertains to the formulation of new products. When formulating a new product, the idea for the product, or the product concept, comes from working with consumers and our company's marketing division.

Why did you choose this career?

I always loved problem solving growing up and chemical engineering was the only subject that really interested me when I entered college. Once I graduated from college I knew I wanted to do work that combined all the skills I learned in college while still allowing me to work with people and see the impact of my work in the world. Going into the consumer product industry allowed me to do all of those things.

Explain what an average day at work is like for you.

My days vary depending on what the team is working on. My days can consist of formulating chemicals in the lab that can be used to clean something specific like mold or mildew. Or, I could be collaborating with our marketing team or consumers to better understand the demands of our customers. I could also be helping with community outreach initiatives, because Clorox takes corporate responsibility very seriously.

What do you like best about your job?

imageSince I work to develop new business and new products, I get to be creative and do a lot of brainstorming with my team to come up with new ideas for products that are not currently on the market. We are always trying to develop products that help consumers with their everyday cleaning or household chores. At the end of the day, it's exciting to see the products I helped develop end up on the grocery store shelves and know that they are helping make peoples' lives easier.

When you were a kid, did you like science, engineering and/or math? If so, what subject did you enjoy most and why?

My dad is a mechanical engineer and he was always encouraging us to explore engineering and math. As a result I was always driven to work really hard at math & science and found myself enjoying those types of subjects over others that were less problem solving (history, etc). I liked that even if I didn't remember the answer, there was a way to figure it out with some thought and work.

Was there a moment when you knew that you wanted to become an engineer? Tell us about it.

There wasn't a defining moment when I decided to become an engineer, but I have always had a strong interest in problem solving, which is kind of the basis of engineering. Growing up I liked Tinker-toys and my favorite TV show was MacGyver, which is a show about a special agent who is armed with so much problem-solving ingenuity.

What was the biggest challenge you faced in your journey to becoming an engineer?

I think the biggest challenge was being a female in an engineering program. Female participation in engineering is definitely growing, but there were not a lot of women in my engineering classes in college. I guess I was really lucky in terms of my support network though. In high school, my parents were really supportive of my pursuit of engineering and in college the department head of the engineering school was very supportive of women.

Was there a person who inspired or convinced you to get involved in your field?

Both of my parents were incredibly supportive of me becoming an engineer. My dad is a mechanical engineer, and while my mom isn't trained in engineering, she works with a lot of engineers. They were able to help me identify that this was something I was really good at and that I could pursue as a career.

Do you have any suggestions for how kids in middle school can get practical experience in your field? Are there any high school courses that you think would be important to take?

There are groups like Girls Inc. that specifically help girls who want to pursue math or science. Also, SWE, the organization I belong to, has so many great resources for kids in middle school interested in an engineering career. Middle school kids should check out any of the engineering association websites, such as, or for fun activities to do. Also, take as much math as possible in high school. Algebra II is required for graduation, but you should also take calculus if your high school offers it. This will help you be more prepared for college if you are pursing engineering. For my specific field of engineering, it would also beneficial to take chemistry before college.

Where do you see your industry going in the future? Are there any exciting changes or innovations that kids pursuing your field can look forward too?

We are always looking for sustainable products, but there will be an even bigger push for this in the future. Things like minimizing product packaging and using safer chemicals or ingredients in our cleaning products are constantly being looked at. As America becomes more health-conscious, consumer product companies will be making product ingredients available to consumers online. You already see a lot of this in the food industry, but it will expand into many other industries over time. Future scientists or chemical engineers will need to keep the product experience good for the consumer, but also integrate the things that people want, such as sustainability.

Do you have closing remarks to encourage students to pursue your field or similar STEM subjects?

Chemical engineering for consumer products is a growing field and is really all about innovation. We're going to need fresh, new ideas and people with different thought processes to execute all of our industry goals. Students pursuing a career in this field can look forward to using their skills for innovation.

Facts to wipe the slate clean...

  • Bleach is derived from sodium chloride, also known as common table salt.
  • French scientist, Louis Pasteur, first used sodium hypochlorite as a disinfectant, which is the active ingredient in bleach. 
  • Formula 409 got its name because its inventors modified their formula 409 times before they were satisfied that it was the ultimate cleaner.
