Application

  • Effect of leave-on cosmetic antimicrobial preservatives on healthy skin resident Staphylococcus epidermidis.: This study examines the impact of various antimicrobial preservatives, including 2-Bromo-2-nitro-1,3-propanediol, on the microbiota of healthy skin, particularly focusing on Staphylococcus epidermidis. The findings suggest that such preservatives can influence the skin′s microbial balance, which is essential for maintaining skin health (Zhang et al., 2023).
  • Assessing the residual antibacterial activity of clinical materials disinfected with glutaraldehyde, o-phthalaldehyde, hydrogen peroxide or 2-bromo-2-nitro-1,3-propanediol by means of a bacterial toxicity assay.: This research assesses the residual antibacterial effects of various disinfectants, including 2-Bromo-2-nitro-1,3-propanediol, on clinical materials, contributing to improved disinfection protocols in healthcare settings (Lerones et al., 2004).
  • Development and testing of a microbiological assay to detect residual effects of disinfectant on hard surfaces.: This study developed a microbiological assay to evaluate the residual effects of disinfectants, including 2-Bromo-2-nitro-1,3-propanediol, on hard surfaces, aiming to enhance surface disinfection strategies in various industries (Mariscal et al., 1999).

Compounds slowly releasing formaldehyde, the so-called formaldehyde-releasers, are commonly employed as preservatives in cosmetics instead of free formaldehyde, which is a strong skin sensitizer. It has been long accepted that formaldehyde-releaser sensitization is attributable to released formaldehyde. However, clinical studies

Formaldehyde and formaldehyde releasers are widely used preservatives and represent an important group of skin sensitizers. Formaldehyde is very often suspected to be the sensitizing agent of formaldehyde-releasers; however, many reported clinical cases of contact allergy to these molecules such
