Yellow 4, also known as Brilliant Yellow or Direct Yellow 4, is an odorless, yellow-orange powder that is most often used as a dye. It is usually utilized as a tint for paper fibers, flax, and cotton. Apart from imparting color onto various materials, Yellow 4 can also be utilized as a water soluble pH indicator.
List of known side effects
Yellow 4 is a skin irritant. Repeated and/or prolonged contact with this substance may result in dermatitis, a skin disease characterized by a rash, itchiness, and red skin.
Should ingestion occur, then Yellow 4 can cause gastrointestinal irritation. This is often marked by bouts of nausea, diarrhea, and vomiting. In the event that this happens, vomiting should never be induced, as it can result in this dye entering the respiratory system or spreading to other parts of the body.
Depending on the route of exposure, Yellow 4 can lead to eye and respiratory tract irritation.
Yellow 4 is a flammable substance, and should never be used in the presence of open flames or sparks.
Body systems affected by Yellow 4
Yellow 4 is a dermal, digestive, ocular, and respiratory irritant, meaning that it’s potentially harmful to the skin, stomach, eyes, and lungs. This substance can be particularly harmful to the skin and stomach if chronic exposure occurs, or if vomiting is induced in the affected person.
