What Everyday Products Contain Corn-Refined Ingredients?

Updated

According to corn.org, the website of the Corn Refiners Association (CRA), corn-derived ingredients show up in far more than food. The site's "Did You Know" series lists laundry detergent, fireworks, cosmetics, shampoo and conditioner, diapers, tires, matches, crayons, frozen pizza, and 3D printing materials as products that rely on cornstarch, corn oil, citric acid, xanthan gum, dextrin, or PLA made through corn refining and bioprocessing. The common thread is that these are refined corn ingredients, not whole corn—each one is produced to serve a specific function like binding, thickening, stabilizing, absorbing, or cleaning.

Why corn ends up in these products

Corn is described on the site as "a versatile resource that can be used for just about everything." Refining and bioprocessing turn the kernel into functional ingredients:

  • Cornstarch acts as a binder, thickener, absorbent, or structural aid.
  • Citric acid, made through bioprocessing, boosts cleaning power and helps soften water.
  • Corn oil works as a conditioner or skin-care ingredient.
  • Xanthan gum, also made through bioprocessing, stabilizes and thickens.
  • Dextrin, a type of cornstarch, serves as an adhesive.
  • PLA, a biodegradable material made from corn bioprocessing, can replace petroleum plastics.

Product-by-product breakdown

Product Corn ingredient What it does
Laundry detergent Cornstarch; citric acid Brightens fabric and removes dirt; increases cleaning power and helps soften water
Fireworks Cornstarch Increases burn time and contributes explosive quality
Cosmetics Cornstarch; corn oil; xanthan gum Found in body powders, skin care, lipsticks, eye and facial makeup; xanthan gum stabilizes and thickens
Shampoo and conditioner Cornstarch; corn oil; xanthan gum Strengthens hair; conditions; stabilizes and thickens
Diapers Starch-based materials; PLA Super-absorbent core; PLA can replace petroleum plastics and outer covers
Tires Bioprocessed cornstarch Rubber reduces rolling resistance and weight for better fuel economy and traction
Matches Cornstarch Binder in match heads and aids ignition; adds rigidity to paper matchsticks
Crayons Cornstarch; dextrin Binds ingredients; dextrin attaches labels
Frozen pizza Modified cornstarch Keeps moisture in the sauce to prevent a soggy crust
3D printing Cornstarch (in some injectable polymers) Being tested as the technology evolves

How to read these claims

Each entry describes a functional role, not a marketing claim—cornstarch in a match head is there to bind and aid ignition, and modified cornstarch in frozen pizza exists to control moisture. The site frames these as examples of how refining "innovates the kernel," and notes that the corn refining industry supports hundreds of thousands of jobs (the excerpt cuts off mid-sentence on economic impact).
