TRS Citric Acid is a food-grade, white crystalline powder and a naturally occurring weak organic acid found in citrus fruits, commonly sold as E330. It is highly water soluble, has a clean sour taste, and is widely used as a flavoring, preservative and acidity regulator in cooking and food manufacture. Because it chelates metal ions and dissolves mineral deposits, it is also effective for household descaling and general cleaning of kettles, coffee machines and taps. The powder is hygroscopic so it should be kept in a tightly sealed container in a cool, dry place away from direct sunlight and moisture. While safe for normal culinary use, concentrated powder can irritate the skin, eyes and respiratory tract; avoid inhaling dust, rinse thoroughly if it contacts skin or eyes, and keep out of reach of children. For any cosmetic or pharmaceutical application, follow tested formulations and local regulations.

To use TRS Citric Acid in the kitchen, add a small pinch to sauces, dressings or preserves to brighten flavor and balance sweetness, increasing slowly to taste; only use citric acid in home canning or pickling when a recipe specifically calls for it, and otherwise follow tested acidity guidelines for safe canning. For household cleaning and descaling, dissolve the powder in warm water to make a clear solution, apply to the limescale or deposit, allow it to sit for a short period, then rinse thoroughly and wipe dry; always test on an inconspicuous area first and follow appliance manufacturers’ care instructions. For bath bombs, cosmetics or other personal-care uses, follow established recipes, avoid undiluted contact with skin and perform a patch test to check for sensitivity.
