Sulisobenzone is a chemical substance that has been registered with the European Chemicals Agency (ECHA). It is a benzophenone derivative, commonly used as a UV filter in sunscreens and other personal care products. This article aims to provide a detailed analysis of Sulisobenzone, focusing on its substance details as provided by ECHA.
Sulisobenzone has the chemical formula C15H10O3 and a molecular weight of 234.24 g/mol. It is a white to off-white crystalline solid, with a melting point ranging from 123°C to 125°C. The substance is soluble in organic solvents such as acetone, ethanol, and methylene chloride, but it is not soluble in water. These chemical properties are crucial for understanding the substance's behavior and potential environmental impact.
According to the classification and labeling inventory of ECHA, Sulisobenzone is classified as a hazardous substance. It is labeled with the following hazard statements: H315 - Causes skin irritation, H319 - Causes serious eye irritation, and H335 - May cause respiratory irritation. The substance is also classified as a skin sensitizer (Category 2) and a respiratory sensitizer (Category 2).
Sulisobenzone is primarily used as a UV filter in sunscreens and other skincare products. It helps protect the skin from the harmful effects of ultraviolet (UV) radiation, which can lead to skin damage and an increased risk of skin cancer. The substance is also used in other applications, such as in the manufacturing of plastics and as a stabilizer in certain types of paints.
Despite its benefits, Sulisobenzone is not without risks. The substance has been identified as a potential endocrine disruptor, which means it may interfere with the normal functioning of the endocrine system. This can lead to adverse health effects, particularly in vulnerable populations such as children and pregnant women. Additionally, the substance may accumulate in the environment and pose a risk to aquatic life.
The European Union has implemented regulations regarding the use of UV filters in cosmetics, including Sulisobenzone. The substance is subject to authorization under the Cosmetics Regulation (EC) No 1223/2009. This means that its use in cosmetics is permitted only if it has been evaluated and authorized by the European Commission. The authorization process ensures that the substance is safe for use and does not pose an unacceptable risk to human health or the environment.
Sulisobenzone is known to be persistent in the environment, meaning it does not break down easily. This persistence can lead to bioaccumulation in organisms, particularly in aquatic ecosystems. The substance has been detected in various water bodies, raising concerns about its impact on aquatic life. Efforts are being made to assess and mitigate these environmental risks, including the development of alternative UV filters that are less harmful to the environment.

In conclusion, Sulisobenzone is a chemical substance that is widely used as a UV filter in sunscreens and other personal care products. While it offers significant benefits in protecting against harmful UV radiation, it also poses certain risks to human health and the environment. The European Chemicals Agency (ECHA) provides detailed information on the substance, including its chemical properties, classification, risks, and regulatory status. This article has outlined the key aspects of Sulisobenzone, emphasizing the importance of responsible use and environmental stewardship.
