Octinoxate
Octyl methoxycinnamate or ethylhexyl methoxycinnamate (INCI) or octinoxate (United States Adopted Name, USAN), trade names Eusolex 2292 and Uvinul MC80, is an organic compound that is an ingredient in some sunscreens and lip balms. It is an ester formed from methoxycinnamic acid and 2-Ethylhexanol, 2-ethylhexanol. It is a liquid that is insoluble in water. It is primarily used in sunscreens and other cosmetics to absorb UV-B rays from the sun, protecting the skin from damage. It is also used to reduce the appearance of scars. Uses Octyl methoxycinnamate is the most common active ingredient in sunscreens for protection against Ultraviolet#Subtypes, UV-B rays. It may be combined with oxybenzone and titanium oxide. Studies have evaluated the efficacy of octyl methoxycinnamate in preventing postoperative peritoneal adhesions and determined that octyl methoxycinnamate covering peritoneal surfaces decreases adhesion formation. This effect is more notable when octyl methoxycinnamate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunscreening Agents
Sunscreen, also known as sunblock, sun lotion or sun cream, is a photoprotection, photoprotective topical product for the Human skin, skin that helps protect against sunburn and prevent skin cancer. Sunscreens come as lotions, sprays, gels, foams (such as an expanded foam lotion or whipped lotion), sticks, powders and other topical products. Sunscreens are common supplements to clothing, particularly sunglasses, sunhats and special sun protective clothing, and other forms of photoprotection (such as umbrellas). Sunscreens may be classified according to the type of #Active_ingredients, active ingredient(s) present in the formulation (inorganic compounds or organic compound, organic molecules) as: * Mineral sunscreens (also referred to as physical), which use only inorganic compounds (zinc oxide and/or titanium dioxide) as active ingredients. These ingredients primarily work by absorbing UV rays but also through reflection and refraction. * Chemical sunscreens, which use organic ...

Oxybenzone
Oxybenzone or benzophenone-3 or BP-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound belonging to the class of aromatic ketones known as benzophenones. It takes the form of pale-yellow crystals that are readily soluble in most organic solvents. It is widely used in sunscreen formulations, plastics, toys, furniture finishes, and other products to limit UV degradation. In nature, it can be found in various flowering plants (angiosperms). The compound was first synthesised in Germany by chemists König and Kostanecki in 1906. The use of oxybenzone as sunscreen ingredient is currently under scrutiny by the scientific community due to controversies about the molecule's environmental impact and safety profile (see section below). As a result, sunscreens containing oxybenzone have been banned from sale in Hawaii, Palau, and Thailand. Structure and electronic structure Being a conjugated molecule, oxybenzone absorbs light at lower energies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii State Legislature
The Hawaii State Legislature ( Hawaiian: Ka ‘Aha‘ōlelo kau kānāwai o ka Moku‘āina o Hawai‘i) is the bicameral state legislature of the U.S. state of Hawaii, consisting of the Hawaii State Senate (upper house with 25 senators) and the Hawaii State House of Representatives (lower house with 51 representatives). Each lawmaker represents single member districts across the state. The powers of the legislature are granted under Article III of the Constitution of Hawaii. The legislature convenes at the Hawaii State Capitol building in the state capital of Honolulu, on the island of Oahu. History The legislature is a descendant of the two houses of the parliament for the Kingdom of Hawaii, the Legislature of the Hawaiian Kingdom, created in the 1840 Constitution of the Kingdom and continued in the subsequent 1852 Constitution as the Legislature of the Hawaiian Islands, consisting of the House of Representatives (Hawaiian Kingdom) and the House of Nobles.

Cinnamate Esters
Cinnamic acid is an organic compound with the formula C6H5-CH=CH- COOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants. It exists as both a ''cis'' and a ''trans'' isomer, although the latter is more common. The ''cis''-isomer is called allocinnamic acid. Occurrence and production Biosynthesis Cinnamic acid is a central intermediate in the biosynthesis of a myriad of natural products including lignols (precursors to lignin and lignocellulose), flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and phenylpropanoids. Its biosynthesis involves the action of the enzyme phenylalanine ammonia-lyase (PAL) on phenylalanine. Natural occurrence It is obtained from oil of cinnamon, or from balsams such as storax. It is also found in shea butter. Cinnamic acid has a honey-like odor; and its more volatile ethyl est ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
