Parabens are esters of para-hydroxybenzoic acid that have been used as preservatives in many types of products for decades including agrochemicals, pharmaceuticals, food and cosmetics. This illustrative case study with propylparaben (PP) demonstrates a 10-step read-across (RAX) framework in practice. It aims at establishing a proof-of-concept for the value added by new approach methodologies (NAMs) in read-across (RAX) for use in a next-generation risk assessment (NGRA) in order to assess consumer safety after exposure to PP-containing cosmetics.

The aim of the Workshop was to formulate strategic ideas to improve and increase the applicability, implementation and acceptance of modern non-animal methods to determine systemic toxicity. The Workshop concluded that good progress is being made to assess repeated dose toxicity without animals taking advantage of existing knowledge in toxicology, thresholds of toxicological concern, adverse outcome pathways and read-across workflows.

These principles were applied to a hypothetical safety assessment of 0.1% coumarin in face cream and body lotion.

Background And Objectives: Rumination is a form of repetitive thinking that has been associated with both helpful and unhelpful consequences for mood and self-regulation. It has been suggested that the specificity of ruminative thought content may be one factor that determines whether state rumination about personal goals is adaptive. The present study tested the hypothesis that state rumination about unresolved personal goals is associated with unhelpful affective consequences only when rumination is low in specificity.
