Direct exposure to highly concentrated Glucono Delta Lactone solutions may result in burning or tearing.
In powdered form, inhaling Glucono Delta Lactone dust may lead to mild respiratory irritation, coughing, or shortness of breath.
Individuals with asthma or pre-existing lung conditions should avoid inhaling fine Glucono Delta Lactone particles.
Although Glucono Delta Lactone is a food-grade ingredient, consuming excessive amounts may cause stomach discomfort, bloating, nausea, or diarrhea due to its acidifying properties.
High concentrations may lead to acidosis, affecting the body's pH balance.
While Glucono Delta Lactone is generally recognized as safe for consumption and industrial use, improper handling or excessive exposure may lead to certain hazards and adverse effects.
Below are the key safety concerns associated with GDL exposure, storage, and handling across different applications.
Glucono Delta Lactone hydrolyzes into gluconic acid upon contact with water, releasing mild acidity.
In industrial settings, improper mixing with alkaline substances may cause unexpected pH shifts.
Reacts with strong alkalis (e.g., sodium hydroxide, potassium hydroxide), leading to heat generation and possible splattering.
When exposed to high temperatures, Glucono Delta Lactone may degrade and lose its functional properties.
