Abstract:
Resorcinol is a frequently used hair dye, whose quantitative risk assessment (QRA) for hair color products is presented in this review as an example to assess its skin sensitization risk after topical application. Its purpose is to determine the maximum concentration that can be used without expecting skin sensitization to occur. The focus is to prevent the de novo development of a contact allergy. Epidemiological data which are provided via dermatological surveillance, e.g., by the IVDK (Information Network of Departments of Dermatology) in Germany, are an important source of information that help to assess the quality and the effectivity of the QRA.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
