| Description | Benzophenone is a combustible, white,crystalline solid with a rose-like odor. Molecularweight=182.23; Specific gravity (H2O:1) = 1.085 at 50℃;Boiling point = 305℃; Freezing/Melting point = 48.5℃;Latent heat of vaporization=2.93 3 105 J/kg; Heat ofcombustion= -358 3 105 J/kg. Hazard Identification(based on NFPA-704 M Rating System): Health 1,Flammability 1, Reactivity 0. Insoluble in water.Diphenyl ketone [119-61-9], benzophenone, C6H5COC6H5, C13H10O, Mr 182.22. The stable form of diphenyl ketone consists of colorless rhombic prismatic crystals. Several unstable forms with lower melting points also exist. Diphenyl ketone is insoluble in water and readily soluble in organic solvents. Diphenyl ketone and substituted diphenyl ketones in particular are used mainly as photoinitiators for UV-curable printing inks and coatings. Diphenyl ketone is also used as an intermediate for pharmaceuticals and agricultural chemicals. It is employed in the perfume industry as a fixative and as a fragrance with a flowery note. |
| Application | Sunscreen cosmetics is the hot new products of cosmetics, almost all sunscreens contain benzophenone compound on the current market. Benzophenone compounds that protect the skin from harm, often is used to produce high product. In recent years, the cosmetics consumption of benzophenone grows continuesly. Recent studies suggest that fluorescence is also a harmful ultraviolet light source, so benzophenone expands the range of applications in the field of cosmetics, it has been extended to hair conditioners, lotions and lipsticks. In addition, the perfume fixative agent also can give spice sweet flavor, is used in many perfumes and soap flavor.
Banana Boat company has developed a UVA ultraviolet-absorbing technology called AvoTriplex, which is benzophenone-based, adding a stabilizer to prevent the benzophenone from breaking down in the sun. Enhancer is also added into the formula, and stabilizer may act synergistically, to optimize benzophenone sunscreen capacity. |
| Uses | Benzophenone Mainly used for the preparation of vanilla, butter and other flavor，It can be used as a fixative agent. Its weak sweet bay leaves fragrant , can be widely used in low-grade flavors, such as roses, bay leaves, sweet curd, shy flower, lily of the valley, sunflower, orchid, hawthorn flowers, incense and Wei Oriental flavor and other flavors. It is also used as an antioxidant in soaps, and occasionally used for almonds, berries, fruit, butter, nuts, peaches, vanilla beans and other food flavors in trace amount.Uses for photosensitive resins, coatings and adhesives.Benzophenone is an intermediate of UV absorbers, organic pigments, pharmaceuticals, perfume, insecticide . It is used for the production of bicyclic Piperidine Benztropine hydrobromide, diphenhydramine hydrochloride in the pharmaceutical industry . The product itself is a styrene polymerization inhibitor and a perfume fixative. Giving sweet taste to flavors, it is used in many perfumes and soap flavors.It is commonly used in soap flavor, used in ultraviolet absorbers, pigments, pharmaceuticals and reagents production, and also is low temperature fast curing agent for fluorine rubber. It serves to manufacturers to package the product in clear glass or plastic.Benzophenone is widely employed as a photo initiator in UV-curing applications such as inks, imaging and clear coatings in the printing industry. It acts as a UV blocker to prevent photo-degradation of the packaging polymers or its contents.It is light initiator for UV products, pharmaceutical intermediates, fragrances, light stabilizers etc.It is light pigment, medicine, perfume, pesticides intermediates, it can also be used for UV-curable resins, inks and coatings initiator.Benzophenone is used as a synthetic intermediate for manufacture of pharmaceuticals and agricultural chemicals. It is also used as a photoinitiator in UV-curable printing inks, as a fragrance in perfumes, as a flavor enhancer in foods. Benzophenone can be added as a UV-absorbing agent to plastics, lacquers, and coatings at concentrations of 2–8%. |
