Tartaric acid (CAS 87-69-4)
Tartaric acid (CAS 87-69-4)
Tartaric acid is a white, crystalline organic acid that occurs naturally in many fruits, most notably in grapes, but also in bananas, tamarinds, and citrus. Its salt, potassium bitartrate, commonly known as cream of tartar, develops naturally in the process of fermentation. It is commonly mixed with sodium bicarbonate and is sold as baking powder used as a leavening agent in food preparation. The acid itself is added to foods as an antioxidant E334 and to impart its distinctive sour taste. Naturally occurring tartaric acid is a useful raw material in organic chemical synthesis. Tartaric acid is an alpha-hydroxy-carboxylic acid, is diprotic and aldaric in acid characteristics, and is a dihydroxyl derivative of succinic acid.

Tetrasodium edetate (CAS 64-02-8)
Tetrasodium edetate (CAS 64-02-8)
Tetrasodium edetate is the salt resulting from the neutralization of ethylenediaminetetraacetic acid with four equivalents of sodium hydroxide (or an equivalent sodium base). It is a white solid that is highly soluble in water. Commercial samples are often hydrated, e.g. Na4EDTA.4H2O. The properties of solutions produced from the anhydrous and hydrated forms are the same, provided they are at the same pH.
It is used as a source of the chelating agent EDTA4-. A 1% aqueous solution has a pH of approximately 11.3. When dissolved in neutral water, it converts partially to H2EDTA2-. Ethylenediaminetetraacetic acid is produced commercially via the intermediacy of tetrasodium EDTA.

Thiourea (CAS 62-56-6)
Thiourea (CAS 62-56-6)
Thiourea is an organosulfur compound with the formula SC(NH2)2. It is structurally similar to urea, except that the oxygen atom is replaced by a sulfur atom, but the properties of urea and thiourea differ significantly. Thiourea is a reagent in organic synthesis. “Thioureas” refers to a broad class of compounds with the general structure (R1R2N)(R3R4N)C=S. Thioureas are related to thioamides, e.g. RC(S)NR2, where R is methyl, ethyl, etc.

Tocopheryl acetate (CAS 58-95-7)
Tocopheryl acetate (CAS 58-95-7)
Tocopheryl acetate, also known as vitamin E acetate, is a synthetic form of vitamin E. It is the ester of acetic acid and α-tocopherol. The U.S. Centers for Disease Control and Prevention says that vitamin E acetate is a very strong culprit of concern in the 2019 outbreak of vaping-associated pulmonary injury (VAPI), but there is not yet sufficient evidence to rule out contributions from other chemicals.
Tocopheryl acetate is often used in dermatological products such as skin creams. It is not oxidized and can penetrate through the skin to the living cells, where about 5% is converted to free tocopherol. Claims are made for beneficial antioxidant effects. α-Tocopheryl acetate is used as an alternative to tocopherol itself because the phenolic hydroxyl group is blocked, providing a less acidic product with a longer shelf life. It is believed that the acetate is slowly hydrolyzed after it is absorbed into the skin, regenerating tocopherol and providing protection against the sun’s ultraviolet rays. Tocopheryl acetate was first synthesized in 1963 by workers at Hoffmann-La Roche.
Toluene (CAS 108-88-3)
Other names: Phenyl methane, Toluol, Anisen, Methyl benzene
Toluene, also known as toluol, is an aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a CH3 group attached to a phenyl group. As such, its IUPAC systematic name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent.

Triclosan (CAS 3380-34-5)
Triclosan (CAS 3380-34-5)
Triclosan (sometimes abbreviated as TCS) is an antibacterial and antifungal agent present in some consumer products, including toothpaste, soaps, detergents, toys, and surgical cleaning treatments. It is similar in its uses and mechanism of action to triclocarban. Its efficacy as an antimicrobial agent, the risk of antimicrobial resistance, and its possible role in disrupted hormonal development remains controversial. Additional research seeks to understand its potential effects on organisms and environmental health.

Triethanolamine (CAS 102-71-6)
Other names: 2,2′,2”-Nitrilotriethanol, Tris(2-hydroxyethyl)amine, Triethylolamine, 2,2′,2″-Trihydroxytriethylamine, Trolamine, TEA, TEOA
Triethanolamine aka Trolamine (abbr. as TEOA to distinguish it from TEA which is for triethylamine) is a viscous organic compound that is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Triethanolamine is a strong base.[3] Approximately 150,000 tonnes were produced in 1999.[4] It is a colourless compound although samples may appear yellow because of impurities.

Turpentine (CAS 9005-90-7)
Turpentine (which is also called spirit of turpentine, oil of turpentine, wood turpentine, terebenthene, terebinthine and (colloquially), turps) is a fluid obtained by the distillation of resin harvested from living trees, mainly pines. It is mainly used as a solvent, and as a source of material for organic syntheses.
Turpentine is composed of terpenes, primarily the monoterpenes alpha- and beta-pinene, with lesser amounts of carene, camphene, dipentene, and terpinolene.
