General description

Diazolidinyl urea is urea derivative that is commonly used as a preservative and antimicrobial agent in cosmetics and personal care products.

Application

  • Impact of cosmetic preservatives on skin cells: A study examined the effects of various cosmetic preservatives, including Diazolidinyl Urea, on healthy human skin cells, highlighting the cellular responses and potential implications for skin health (Głaz et al., 2023).
  • Formaldehyde releasers in personal care: An extensive clinical review discussed allergic contact dermatitis caused by formaldehyde and formaldehyde releasers such as Diazolidinyl Urea, providing insights into allergic reactions and safety concerns in dermatological practice (Goossens and Aerts, 2022).
  • Carcinogenic potential of cosmetic ingredients: Research on potential carcinogens in makeup cosmetics included Diazolidinyl Urea, emphasizing the safety and regulatory aspects concerning its use in cosmetic formulations (Balwierz et al., 2023).
  • Patch testing for allergen sensitivity: A study integrated Diazolidinyl Urea in a patch test series to evaluate skin sensitization and allergic reactions in patients, aiding in the assessment of its allergenic potential (Bizjak et al., 2022).
