Chemical and Product Categories (CPCat) database

The EPA CPCat (Chemical and Product Categories) database was released in May 2014. It maps >43,000 chemicals to a set of terms categorizing their usage or function. We have compiled a comprehensive list of chemicals with associated categories of chemical and product use by compiling publicly available sources. Sources include, but are not limited to: the Substances in Preparation in Nordic Countries (SPIN) database, information provided by companies, trade associations, and regulatory agencies such as the U.S. Environmental Protection Agency (EPA) and Food and Drug Administration (FDA), the DrugBank database of pharmaceutical products, and information mined from the Aggregated Computational Toxicology Resource (ACToR) database developed by the U.S. EPA. Unique use category taxonomies from each source are mapped onto a single common set of ~800 terms. The user can search for chemicals by chemical name, Chemical Abstracts Registry Number (CASRN), or by CPCat terms (i.e. category names) associated with chemicals. See Dionisio et al., 2014 for a full description of the database, sources used, interpretation of chemical categories, and potential applications. The .zip file available at the "Download" tab of this website provides a full copy of the database, available for free download, which can be freely searched and sorted for data analysis. The .zip file includes a list of all chemicals included in CPCat. A list of all sources included in CPCat is provided in the table below.美国环境保护署（U.S. Environmental Protection Agency, EPA）的CPCat（Chemical and Product Categories，化学品与产品分类）数据库于2014年5月发布。该数据库将超过43000种化学品映射至一组用于描述其用途或功能的术语体系。我们通过整合公开可获取的数据源，编制了一份涵盖化学品及其相关化学品与产品用途分类的完整清单。所使用的数据源包括但不限于：北欧国家制备物质（Substances in Preparation in Nordic Countries, SPIN）数据库、企业、行业协会及监管机构提供的信息，例如美国环境保护署（EPA）、美国食品药品监督管理局（Food and Drug Administration, FDA）、医药产品数据库DrugBank，以及由美国EPA开发的综合计算毒理学资源（Aggregated Computational Toxicology Resource, ACToR）数据库中挖掘得到的信息。我们将各数据源独有的用途分类分类法映射至一套包含约800个术语的通用分类体系。用户可通过化学品名称、化学物质登记号（Chemical Abstracts Registry Number, CASRN）或与化学品关联的CPCat术语（即分类名称）检索化学品。有关该数据库、所用数据源、化学品分类解读及潜在应用场景的完整说明，请参阅Dionisio等人2014年的研究成果。本网站“下载”标签页提供的压缩文件（.zip）包含该数据库的完整副本，可免费下载，且可自由进行检索与排序以用于数据分析。该压缩文件包含CPCat收录的所有化学品清单。下表列出了CPCat收录的全部数据源。
