Popular questions
Is tricalcium phosphate the same as calcium citrate?
No—tricalcium phosphate (E341iii) and tricalcium citrate (E333iii) are different calcium salts; citrate is more soluble and mainly used as a sequestrant/stabilizer and calcium fortificant, while phosphate is often an anti-caking agent and fortificant.
Is tricalcium citrate bad for you?
No—tricalcium citrate (E333iii) is approved in the EU and generally recognized as safe in the U.S. at typical food levels; excessive calcium from any source can cause GI discomfort or contribute to kidney stones in susceptible people.
What is tricalcium citrate used for?
It’s used as a sequestrant and stabilizer to control acidity and bind metal ions, helping preserve color and texture, and it’s also used to fortify foods and supplements with calcium.
Which is better calcium citrate vs tricalcium phosphate?
For calcium supplementation/absorption, calcium citrate is often preferred because it’s more soluble and can be taken with or without food; tricalcium phosphate is less soluble but useful in foods as an anti-caking agent and when added phosphorus is desired.
Which is easier to absorb tricalcium pjosphatw or calcium citrate?
Calcium citrate is generally easier to absorb than tricalcium phosphate, especially on an empty stomach; phosphate salts are better absorbed when taken with meals.
Why is triacetin bad for you?
It isn’t generally considered bad for you—regulators (e.g., EU as E1518; JECFA/EFSA) regard it as safe at permitted food-use levels and it’s metabolized to glycerol and acetate. Large exposures can cause mild gastrointestinal upset if ingested or irritation on skin/eyes from the neat liquid.
What is triacetin made from?
Triacetin is the triester of glycerol and acetic acid, typically produced by acetylating glycerol with acetic acid or acetic anhydride.
What is triacetin used for?
In foods it serves as a carrier/solvent for flavors, humectant, and emulsifier (and plasticizer in gum base); it’s also used in pharmaceuticals and cosmetics as a solvent and plasticizer for capsules and topical formulations.
How to make triacetin?
Industrially it’s made by esterifying glycerol with acetic acid or acetic anhydride in the presence of an acid catalyst, then removing water and purifying (e.g., by distillation) to obtain glycerol triacetate.
How triacetin acts as penetration enhancer?
As a lipophilic solvent/plasticizer, triacetin partitions into stratum corneum lipids, increases their fluidity, and improves drug partitioning and diffusion; it can also raise the solubility of actives at the skin surface.
