Mono T-butyl Hydroquinone (MTBHQ) is a secondary inhibitor (co-inhibitor) and antioxidant. For nonfood fats, oils and unstable organic solvents, it's a highly effective antioxidant. In unsaturated polyesters, it's used as a storage inhibitor.
Applications:
-Retarder:

Product Description
Mono T-butyl Hydroquinone (MTBHQ) is a light tan solid.
Mono T-butyl Hydroquinone (MTBHQ) is used primarily as a polymerization inhibitor and industrial antioxidant.
Mono T-butyl Hydroquinone (MTBHQ)s higher solubility and increased potency at higher temperartures combine to make it more useful in many applications than unsubstituted hydroquinone. The hindered hydroxyl group also makes Eastman™ MTBHQ an interesting organic intermediate.
Mono T-butyl Hydroquinone (MTBHQ) is a preservative and antioxidant used in various applications. Derived from hydtert-Butylhydroquinone, it is a synthetic organic phenol made by substituting one of the ring hydrogen’s of hydroquinone with a tert-butyl group.
Mono T-butyl Hydroquinone (MTBHQ) has a slightly aromatic scent with an off-white appearance, and usually comes the form of a powder that is highly soluble in water.
Applications:
Most perfume aficionados will tell you that fragrances are dynamic and that they start to change from the moment they touch our skin. When perfumers, referred to as Noses in the industry, aim to create a fragrance they use their expertise to formulate a scent combination that is pleasant, long lasting, and subtly noticeable; this conspicuousness is known as a sillage and refers to the pleasant trail left behind by the wearer. To increase the longevity and sillage of the fragrance, perfumers can reduce its evaporation rate by using Mono T-butyl Hydroquinone (MTBHQ) as a stabiliser, whilst simultaneously postponing degradation. At the recommended concentrations, Mono T-butyl Hydroquinone (MTBHQ) exhibits no odour making it ideal for cosmetics and perfumes alike.
Mono T-butyl Hydroquinone (MTBHQ)s antioxidant properties make it an excellent stabiliser that can prevent evaporation, discolouration, and spoiling of the solvent to which it is added.
In food, Mono T-butyl Hydroquinone (MTBHQ) is used for its preservative properties (E number E319).
Mono T-butyl Hydroquinone (MTBHQ) is used extensively in unsaturated vegetable oils and animal fats to extend the shelf life of products.
Mono T-butyl Hydroquinone (MTBHQ) benefits from a high solubility in both water and oil which makes it suitable for a wide variety of end products. Although Mono T-butyl Hydroquinone (MTBHQ) is FDA approved, some evidence suggests that in large quantities it could cause harmful side effects.
