The Effect of Select Personal Care Ingredients and Simple Formulations on the Attachment of Bacteria on Polystyrene

The human body is covered with bacteria that are required for health and wellbeing. Additionally, there are pathogenic bacteria that are unwanted. It is therefore important to understand how personal care ingredients interact with these bacteria. To help understand these interactions, a high-throughput assay was developed to study the effect of personal care ingredients on attachment. Seventeen personal care ingredients were assayed singly and in simple alcohol based formulations. Three of the ingredients decreased the attachment of both bacteria tested by 90% singly and in formulation. Personal care ingredients singly and in simple formulations can prevent the attachment of bacteria. Further research is needed to better understand how personal care ingredients affect bacterial attachment and how these effects can be used to create new hygiene products for consumers. View Full-Text
