It is most concentrated in: 1. Used when there is a risk of localised corrosion only if crevices are present. Soldering flux. Citrate is a positive modulator of this conversion, and allosterically regulates the enzyme acetyl-CoA carboxylase, which is the regulating enzyme in the conversion of acetyl-CoA into malonyl-CoA (the commitment step in fatty acid synthesis). Citric Acid 50% Solution is a clear or yellow to brown liquid, with a faint sugary odor. Citric Acid 50% Solution is a clear or yellow to brown liquid, with a faint sugary odor. When Acetic Acid is diluted to the concentrations found in Vinegar and used in cosmetic products it is not irritating to the skin. This effect is advantageous: high concentrations of citrate indicate that there is a large supply of biosynthetic precursor molecules, so there is no need for phosphofructokinase to continue to send molecules of its substrate, fructose 6-phosphate, into glycolysis. Its salt, potassium bitartrate, commonly known as cream of tartar, develops naturally in the process of winemaking. The pH of acids range from 1-7. (Used only where there are no actual data to estimate the risk of localised corrosion instead of p or s). Sodium citrate is a component of Benedict's reagent, used for identification both qualitatively and quantitatively of reducing sugars. CITRIC ACID Ingestion May irritate and cause stomach pain, vomiting and diarrhoea. The amount of citric acid added to packaged foods is quite low. High concentrations of cytosolic citrate can inhibit phosphofructokinase, the catalyst of a rate-limiting step of glycolysis. Product dust may cause mild, mechanical irritation. Inhalation May cause irritation of respiratory tract. The corrosion data apply to annealed materials with normal microstructure and clean surfaces, throughout. Citric acid can be used in shampoo to wash out wax and coloring from the hair. Hydrochloric acid and even inhibited hydrochloric acid based products, the corrosion rate is much higher and simply cannot be considered non-corrosive by any legitimate definition. It is used in cosmetic chemical peels. It is corrosive, not a high corrosive, unless it is very concentrated, but a corrosive none the less, it can burn skin and eyes. Even so, it's probably the most dangerous acid in this list because it's the one you're most likely to encounter. Citric acid has also been used in preparations for the treatment of gastrointestinal disturbances and chronic metabolic acidosis caused by chronic renal insufficiency or syndrome of renal tubular acidosis [1,2,4–6,20,21,79].
