Croda recently highlighted its sustainable ingredients that contain less than 1ppm of the compound 1,4-dioxane. The trace contaminant is found in some cosmetic products that form it as a byproduct during the manufacturing process.
Although 1,4-dioxane is not used as an ingredient in cosmetics, it may be present in extremely small amounts. These ingredients include certain detergents, foaming agents, emulsifiers and solvents.

Croda products that have been tested by a third party and verified to contain less than 1ppm 1,4-dioxane include:
Enriching Body Butter —This body butter can help the skin bounce back from the effects of persistent washing and dehydration.
Botanical Bubbles Baby Shampoo — This sulfate-free and fragrance-free shampoo is formulated to be delicate enough for a baby’s scalp while also providing clean and refreshed hair.
Ingredients featured in these formulas include:
ECO Brij S2 MBAL (INCI: Steareth-2) — A polyoxyethylene fatty ether derived from stearyl alcohols designed to emulsify and produce stable dispersions of cosmetic materials.
Crodasinic LS30 (INCI: Water (Aqua) (and) Sodium Lauroyl Sarcosinate) — A mild anionic surfactant produced from a natural fatty acid and that generates a rich, creamy lather.
Crodamol ISIS (INCI: Isostearyl Isostearate) — A naturally derived emollient with demonstrated skin moisture-barrier effects that also protects the skin.
The FDA considers 1,4-dioxane a potential human carcinogen and is listed as an animal carcinogen. Limits on the amount of the compound are being established for a variety of products. New York State passed a law that will only allow <1 ppm of 1,4-dioxane in personal care products.
