Valisure, an independent laboratory, filed a Citizen Petition with the FDA in March 2024, raising concerns about ben...
雅诗兰黛等知名护肤品含致癌化学成分 | 美国独立实验室Valisure称,它在多个化妆品牌的一些痤疮(acne)治疗产品中检测到高含量的致癌化学物质苯(benzene)。实验室向美国食品与药物管理局(FDA)提交请愿书,要求FDA召回这些产品,展开调查并审查行业指南。 路透社报道,总部位于康涅狄格州纽黑文的实验室星期三(3月6日)发布化验...
Most benzoyl chloride is used in the production of benzoyl peroxide, and secondly for the production of benzophenone, benzyl benzoate, and benzyl cellulose. Benzoyl peroxide catalyzes polymerization initiator for the monomer plastic, polyester, epoxy, acrylic resin production, self-curing agent, which ...
Benzoyl peroxide was decomposed in benzene in the presence of O 2 at various temp, and the reaction products were determined. The ratio of phenol to biphenyl formed depends on the reaction temperature and shows that phenyl radicals react with oxygen with a greater activation energy than with ...
The mechanism of the benzophenone and 2-acetonaphthone sensitized decomposition of benzoyl peroxide in benzene has been investigated. When benzophenone is the sensitizer, the yield of acid resulting from peroxide decomposition increases as the initial peroxide concentration decreases. We interpret this to...
The addition of benzoyl peroxide (BPO) decreased the melt flow rate (MFR) and increased the impact strength of the recycled polymer blends. Divinyl benzene (DVB) is often used as a cross-linking agent assistant. Compared with BPO modification, the addition of BPO together with DVB improved ...
We observed that pyridine could induce the decomposition of benzoyl peroxide, the reaction of which was first-order with respect to the peroxide and pyridine, respectively, to give pyridine N-oxide and benzoic anhydride. We demonstrated that pyridine cation radicals are not formed in the reaction....
A kinetic study has been made of the decomposition of benzoyl peroxide in benzene. Kinetic data for this study have been obtained from three separate sets of measurements. Rate measurements from evolved carbon dioxide and direct iodometric measurements of peroxide are in good agreement. Alkali-metric...
