Comparing E150C - Ammonia caramel vs E527 - Ammonium hydroxide

What color is caramel?

E150c (ammonia caramel) imparts a brown to deep brown, often slightly reddish-brown, color to foods and drinks.

What is caramel color made of?

Class III caramel color (E150c) is made by heating carbohydrates (such as glucose or sucrose syrups) with ammonium compounds, without sulfites, creating complex brown polymers.

Does caramel color cause cancer?

E150c can contain trace 4‑methylimidazole (4‑MEI), a byproduct linked to tumors in high‑dose animal studies. Typical dietary exposures are low, and regulators like FDA, EFSA, and JECFA consider caramel colors safe at normal use levels (California’s Prop 65 sets a warning level for 4‑MEI).

Does caramel color have gluten?

No—caramel color (including E150c) is gluten‑free; even when sourced from wheat, processing removes gluten proteins, though you can confirm with the manufacturer if needed.

How to lighten dark brown hair to caramel color?

E150c is a food colorant and isn’t intended for hair dye; use cosmetic hair‑color products and consult a professional stylist for safe lightening.
