Tributyl citrate (TBC) is an organic ester formed by reacting citric acid with butanol. It is a colorless liquid and is primarily used as a plasticizer in various plastic materials, especially in polyvinyl chloride (PVC). TBC is also used in cosmetics and personal care products as a softener and in nail polish as a solvent.
Replacement for DEHP and DINP:
Tributyl citrate is used as a replacement for more problematic plasticizers like DEHP (di(2-ethylhexyl)phthalate) and DINP (diisononylphthalate), which have been criticized for their potential health and environmental impacts. TBC is considered a safer alternative in many applications as it is less harmful and is not suspected to have endocrine-disrupting effects in the same way that some phthalates do.
Use in cosmetics:
In cosmetics, tributyl citrate (TBC) is used as a plasticizer in products such as nail polish and other skincare products. It helps improve the texture and stability of the product.
Acetylation of Tributyl citrate:
The part where you mention that tributyl citrate (TBC) is produced by “acetylation of tributyl citrate” may be a misunderstanding, as tributyl citrate itself is the result of esterification of citric acid and butanol (not acetylation). Acetylation refers to a chemical process where an acetyl group (-COCH3) is added to a molecule, which is a different type of chemical reaction typically not associated with the production of tributyl citrate.
Summary:
Tributyl citrate (TBC) is an organic ester primarily used as a plasticizer in plastics and as an ingredient in cosmetics, especially in nail polish and skincare products.
Tributyl citrate (TBC) is a health-safer alternative to phthalates like DEHP and DINP.
It is produced through esterification of citric acid and butanol.
Tributyl citrate (TBC) is available in bulk, IBC, drums, and cans.
