Is Triphenyl Phosphate bad for you?
* Triphenyl Phosphate may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash. * Triphenyl Phosphate may affect the liver and kidneys. * High or repeated exposure may damage the nerves causing weakness, “pins and needles,” and poor coordination in the arms and legs.

Triphenyl phosphate/Formula
Does nail polish contain triphenyl phosphate?
Triphenyl phosphate (TPHP) is primarily used as either a flame retardant or plasticizer, and is listed as an ingredient in nail polishes. Our results indicate that nail polish may be a significant source of short-term TPHP exposure and a source of chronic exposure for frequent users or those occupationally exposed.
Where does triphenyl phosphate come from?
Triphenyl phosphate is an aryl phosphate resulting from the formal condensation of phosphoric acid with 3 mol eq. of phenol. It has a role as a flame retardant and a plasticiser. It derives from a phenol.
Which is triphenyl methane dye?
triphenylmethane dye, any member of a group of extremely brilliant and intensely coloured synthetic organic dyes having molecular structures based upon that of the hydrocarbon triphenylmethane. Crystal violet, the most important of the group, was introduced in 1883. …
What does triphenyl phosphate do in nail polish?
Triphenyl phosphate, or TPHP, makes nail polishes more flexible and durable, and is also used to make plastic and to stop foam furniture from catching fire. It may have been introduced to nail polishes to replace phthalates, which studies have linked to reproductive issues.
Is triphenyl phosphate an endocrine disruptor?
Triphenyl phosphate, or TPHP, a suspected endocrine-disrupting chemical, is commonly used to make plastics and as a fire retardant in foam furniture.

Is pph3 a base?
PPh3 is a weak base. It forms isolable triphenylphosphonium salts with strong acids such as HBr: P(C6H5)3 + HBr → [HP(C6H5)3]+Br.
Is phosphate an ester?
Phosphate has three pKas (2.2, 7.2 (5.8 as an ester) and 12.4) and is highly soluble in water, forming a large hydrated ionic shell. Phosphate is chemically versatile and can form mono-, di- and tri-esters with alkyl and aryl hydroxyl groups, as well as acid anhydrides.
